Jorge just put this question from Jeff Atwood on twitter looking for someone to help: askubuntu.com/questions/761031/…

hbdgaf

"
I faced the same issue but now every thing works fine.

The main issue is with gdm not the nvidia driver so just install lightdm & make it the default dm then install the nvidia driver.
"

Might be a thanks. Might be a "bug wasn't the driver" separate answer.

Videonauth

apt-get nuke-from-orbit 127.0.0.1

Thomas W.

@hbdgaf I interpreted it as the second one

because it proposes a solution

and isn't just "Thanks"

Zacharee1

@hbdgaf well, I think that could be an answer, but like my comment says, there's no one issue to have there

It's a solution, but we don't know what for

chaskes

00:02

I read it as a separate answer

Thomas W.

"just install lightdm & make it the default dm then install the nvidia driver. " <-- that could be an answer

@chaskes Same

Zacharee1

I think they had an issue with login loops, but idk

Thomas W.

@hbdgaf So I think there's only been the one true "Thanks!" without anything else added here

hbdgaf

@ThomasW. fair enough

Zacharee1

Yay, I can accept my answer now!

hbdgaf

00:03

@chaskes That's a tough one.

maybe he could install 16.04 then boot live 14.04. chroot. and update-grub

TheXed

Sup?

chaskes

@hbdgaf Yeah but despite what he said, I'm not sure he's getting the bootloader to /dev/sdc, although I haven't read super closely.

Q: How to configure Bluetooth Tethering (Smartphone/Laptot) to autostart automatically when I turn on the computer?

I would like to know the way I turn on my computer and it active automatically my Bluetooth Tethering connection (my Internet connection). Now every time I turn on I have to do it manually. Do I have to modify my Bluetooth configuration or my network configuration? My knowledge on this subject ar...

But do you want it automatic?

TheXed

00:06

@hbdgaf hows life treating you?

Nathan Osman

I'm having one of those "the idea seemed simple on paper" moments.

TheXed

@Zacharee1 why not green?

hbdgaf

@TheXed well enough

Zacharee1

because

Videonauth

Congratulations!

This was only a test, designed to make sure you were paying attention. You passed. This post has already been removed, but thanks for considering leaving feedback for its author.

lol 4 tests in a row

Zacharee1

00:06

noice

TheXed

@NathanOsman does it involve my store link? :-P

Zacharee1

You must have done something O_o

TheXed

@hbdgaf good to hear.

Nathan Osman

@TheXed I don't want to install any packages until my APT cache script is up and running.

TheXed

and what does the script do @NathanOsman?

chaskes

00:07

@hbdgaf I just noticed that Braiam is working with him, so my two cents aren't needed.

Zacharee1

@TheXed starts the Armageddon

Nathan Osman

@TheXed It acts as an HTTP proxy, caching packages.

@Zacharee1 Shhhhhh!

hbdgaf

@chaskes Yep. He has been notably absent from chat for a LONG time.

Zacharee1

:)

TheXed

So it caches packages? for what?

chaskes

00:08

I think he got tired of arguments, but I miss having him around.

Zacharee1

@TheXed I told you, the Armageddon

TheXed

@Zacharee1 lies...

Nathan Osman

@TheXed Reducing Internet bandwidth?

I've got three or four machines (plus countless chroots) all pulling the same packages.

That's not good.

Enter script.

Now a package only needs to be fetched once.

Zacharee1

@TheXed le trooth

hbdgaf

And you're not using something like apt-cacher and pointing it to your local repo because?

TheXed

00:10

@NathanOsman Oh I see...

Videonauth

@Zacharee1 O_o askubuntu.com/a/762123/522934

Nathan Osman

@hbdgaf apt-cacher doesn't properly handle mirrors.

Videonauth

shudders

Nathan Osman

I was using squid-deb-proxy but it was still duplicating stuff.

hbdgaf

@NathanOsman ah, ok.

TheXed

00:11

@NathanOsman probably faster that way too...download once, distribute many times...via your LAN

Nathan Osman

And it really wasn't all that easy to configure.

Thomas W.

@NathanOsman apt-cacher or apt-cacher-ng?

Nathan Osman

@TheXed Exactly.

@ThomasW. I think he meant *-ng.

Thomas W.

ah

hbdgaf

I meant ng

Nathan Osman

00:12

Yup, when my little app is complete, it will be a single binary with a single parameter - the directory to cache files to.

chaskes

Does anyone know offhand how the textual installer chooses the drive for grub? Does it automatically offer the same drive as /, or does it default to /sda? In the second case if the hard drive came up as /sdc, you would definitely have to switch the grub target.

Nathan Osman

Then I just point all the machines to it (by setting an HTTP proxy) and presto!

TheXed

I am thinking about shutting down my minecraft server...

hbdgaf

@NathanOsman And it will be written in Go. Free of dependencies. - guessing

Thomas W.

@NathanOsman on that bug, I marked it 'Incomplete" as we are missing info :P

Zacharee1

00:12

@NathanOsman presto! apt issues :p

Nathan Osman

@hbdgaf Of course.

@Zacharee1 Issues?

TheXed

I don't think anyone has logged into it for over a year...

hbdgaf

I find your fascination with Go and reliance on Qt/C++ concurrently a little odd.

Zacharee1

@NathanOsman all those questions about apt-get * trouble through a proxy? :p

@TheXed gimme teh IP

TheXed

joshuapbell.com

Nathan Osman

00:14

@Zacharee1 Never had a problem like that.

The proxy is on the LAN.

Zacharee1

@TheXed thx

Zacharee1

Videonauth

i guess that the equivalent of saying jehova just on linux lol

lets stone him

hbdgaf

geez. people can complain about anything. Example here - the negative review was "It is a combination alarm clock and timer that tucks away neatly in your appindicator dock, but it's limited to a 99 hour timer. Boo. Uninstalling" <-- really?

Videonauth

00:23

:p

Zacharee1

@hbdgaf haha

Nathan Osman

I think when you need to time something longer than 99 hours, it's time to use a calendar app, not a timer.

Zacharee1

seriously

hbdgaf

Yes. Or increments in days, and you set your timer to a "work-day"

@Zacharee1 I'm serious by the way. That's give or take what the negative review said.

Zacharee1

I saw it

When you're bored...

Aren't these great?

hbdgaf

00:30

Must have been timing how long he could keep a plant alive or something... I don't know.

Videonauth

@hbdgaf lol

Zacharee1

@hbdgaf But that would need a stopwatch

hbdgaf

@Zacharee1 "My neighbor bet me I couldn't keep this plant alive for 999 hours" is the only scenario I could come up with.

Zacharee1

lol

hbdgaf

It would fit with the derp jewelry you posted. Shaved head for losing the bet and all.

Also, if we get release names after pirates, I may die of a heart attack.

Toow for making flowcharts

Nathan Osman

@RPiAwesomeness that is so cool.

@RPiAwesomeness did you ever get Hectane up and running?

Videonauth

@RPiAwesomeness indeed very neat tool (bookmarked it)

RPi Awesomeness

Would any mods be able to edit my link above and make the text a bit more useful (describe what it is)

Zacharee1

cool'

RPi Awesomeness

@NathanOsman I think so. I haven't had a chance to test it out yet, but I plan on doing so soon

Nathan Osman

@RPiAwesomeness what language are you calling to it from?

RPi Awesomeness

@NathanOsman Going to be JS

Probably via a jQuery AJAX request

Nathan Osman

00:51

Cool.

Do you want an example?

Or do you want that to be part of the challenge? :D

One thing to keep in mind - the same-origin policy may block the AJAX request unless you're serving from the same host:port.

RPi Awesomeness

I'll try it myself :)

Nathan Osman

Hectane doesn't do CORS, which, come to think of it, might not be a bad idea for a feature.

RPi Awesomeness

For now anyways

Nathan Osman

Cool.

btw guys, Jeff Atwood asked us a question:

Q: Ubuntu Server 16.04 installs on /sdc but fails to boot

I am doing a clean install of Ubuntu Server 16.04 LTS on a machine with a single internal SSD. After completing the install, the system fails to boot and prints a single line fsck output, with the rest of the screen entirely blank. This very same server installs Ubuntu Server 14.04.4 LTS just ...

grub2 system-installation 16.04

Mateo

holding the home key on the mx4 brings them up too

Seth

we should answer it

@Mateo sweet!

Mateo

not that you have numbers on there... but it does give you a quick way to tap something over there

Zacharee1

@TheBrownOne you're too late again :p

Mateo

01:08

@Seth hrm, picture text. is this a test?

Seth

@Mateo can't copy text off a console... :/

@Fabby @cl-netbox @Rinzwind any ideas --^

Mateo

yeah, on install

Seth

(sorry, mass pinging on this one :P)

Mateo

so, we will let him off the hook ;)

chaskes

@Seth Yeah, Jorge put the Jeff's question on twitter a little earlier. I suspect its's either incompatible firmware or unsigned firmware with secure boot, but I don't know for sure.

Seth

01:12

@chaskes that's interesting, since it worked on 14.04.

Mateo

didn't something similar come up in chat

Seth

(Jorge also posted on G+, where I saw it)

chaskes

14.04 didn't enforce the signed firmware. that's causing a lot of people trouble with realtek wireless

Mateo

yeah, basically you could install with grub, then boot anything with that effectlivly geting around secure boot

chaskes

the fact that 14.04 worked is what makes me think it's a signing issue. but there's no reason a regression in the kernel couldn't cause new incompatibilities in 16.04 that weren't in 14.04

Seth

01:15

you should comment about that @chaskes

Mateo

Solution, don't buy something made for windows...

chaskes

@Seth I was just re-reading the comments in order to do that

Nathan Osman

@Seth I retweeted it.

That's about the best I can do.

Seth

@NathanOsman I pinged Fabby :P

Nathan Osman

Every SSD I've used (and that includes USB installs) shows up as /dev/sda.

So I have no idea why it's showing as /dev/sdc.

To be fair, I've only done one 16.04 install so far though...

Mateo

01:17

1 hour ago, by chaskes

Does anyone know offhand how the textual installer chooses the drive for grub? Does it automatically offer the same drive as /, or does it default to /sda? In the second case if the hard drive came up as /sdc, you would definitely have to switch the grub target.

Going to post some chat searches, don't know if revelant

Nathan Osman

It shouldn't boot at all if Grub isn't installed to the right drive/partition.

chaskes

@Seth Ok, commented.

Seth

@chaskes cool! Learn something every day :)

chaskes

@NathanOsman I've had several installs show the usb as /dev/sda and the hdd as /dev/sdb. If I have a 2nd usb in there (say, for debian non-free drivers) all bets are off on which is a,b, c. From what I've read, it's a race condition,

@Seth That's about the sum of my knowledge on that issue, though. If he askes a follow-up, I'm out.

Nathan Osman

@chaskes Yeah, that makes sense.

The installer should default to an internal drive (SATA) if present.

Mateo

01:21

Oh, that was just eariler about the same thing huh..

chaskes

Yeah, but it doesn't make an difference form an installation point of view so they prob figure why bother, but it would help with user experience.

Mateo

I wonder if fastboot is on or something

chaskes

I just commented that he should make sure secure boot is off.

Mateo

Yeah all that stuff turn it off, maybe disable some of the other boot devices, put the disk on top

Nathan Osman

Something doesn't look right. The second partition is of type 5 (DOS 3.3+ Extended Partition) which doesn't support partitions larger than 8.4 GB. According to this page, "Using type 05 for extended partitions beyond 8 GB may lead to data corruption with MSDOS." — Nathan Osman 14 secs ago

^--- a clue?

Oh wait.

Never mind.

I see what's happening there.

On a side note, I don't think he needs 16 GB of swap.

chaskes

01:27

What is happening there? It looks look a normal auto created layout

user139252

@Zacharee1 what happened?

chaskes

He must be testing some heavy, swapable server stuff

Mateo

lol link him the swap guide ;p

Nathan Osman

@chaskes I don't think you want a server using that much swap. You would want to install more RAM.

Zacharee1

@TheBrownOne I wanted someone to proofread my thesis paragraph, but I sent it already

Mateo

01:29

but yeah, swap on a sSd would be fast, and you don't want to thrash it moving things in and out

chaskes

@NathanOsman I'm just suggesting he probably has a reason to want that much swap or to think he does. :) but @Mateo you're right, I forgot about the no swap on an ssd

Nathan Osman

I've got 8 GB of RAM and only 1 GB of swap. I have yet to need more than that.

chaskes

True, but he's only asking for help on getting it to boot, not the partition layout. :)

Nathan Osman

I know :D

Mateo

Well, wasn't there something about having some swap on your primary drive?

Nathan Osman

01:32

I wonder what swap would be like on this guy? accessories.us.dell.com/sna/…

chaskes

just saw lubuntu 16.04 for R Pi is out

Williams Abraham Perez Crazut

Great! :)

Nathan Osman

Whoa...

Anyone have $18,000?

accessories.us.dell.com/sna/…

Why on earth is that so expensive?

Williams Abraham Perez Crazut

That's a monster :0

Nathan Osman

I could build a RAID 0 array with the same amount of space and similar performance for at least half that.

Williams Abraham Perez Crazut

01:34

You're right!

And could have a better perfomance!

Mateo

hm, maybe special application

chaskes

@NathanOsman Because it's designed to work with only 1 model of server, which lowers the number of units they can sell and so dramatically increases the unit cost for the break even point.

Mateo

maybe a space limited application - only 1 drive bay to use

heat, power, ect...

Videonauth

Anyone who can me in detail what this line (dont run it in terminal it wil clog down your computer) does

:(){ :|: & };:

Nathan Osman

amazon.com/Intel-P3608-Internal-Solid-SSDPECME040T401/dp/…

Still expensive but about half the price.

something like that anyway ;)

TheXed

Hi.

Serg

Thank you for all the suggestions, but . . .nothing works. I've been up and down the stty and screen manuals, i've used putty, i've changed mcu source code, baud rate, individual config bits. Basically the result is the same: nothing works and no one know why — Serg 54 secs ago

TheXed

@Serg what did you break this time>

?

Nathan Osman

Serg

01:41

@TheXed that's the whole point - i didn't break anything

Nathan Osman

Uhhh....

Slow and lacked space?

Nice try, troll.

WHO ARE THE 19 IDIOTS WHO FOUND THAT HELPFUL???!?

Serg

My MCU works with windows, receives ascii chars from keyboard alright, but on linux it's not working

TheXed

@NathanOsman what was that for?

Serg

I get now . . . C1 for 61 , C2 for 62 and so on

Nathan Osman

@TheXed The review I posted a screenshot of.

Videonauth

01:42

@NathanOsman if you browse through amazon you will dinf many of those, and people voting it helpfull because they think it is funny

Nathan Osman

That isn't even close to funny.

Seth

me either.

now you made my message make no sense -.-

Nathan Osman

Sorry :/

Seth

:P

TheXed

@NathanOsman No I meant what was the review for?

Nathan Osman

01:45

The Intel SSD I linked to above.

Videonauth

4TB internal SSD

TheXed

Oh!

Nathan Osman

When 5000 MBps is "a bit slow", that's a good sign someone is a troll. That's 40 Gbps folks.

TheXed

@NathanOsman or they don't know what they are doing with it...

Videonauth

well i would be more concerned that it laks the space to store minesweeper

:p

Nathan Osman

01:46

It's 4 TB.

Williams Abraham Perez Crazut

What you guys recommends to me, I recently installed Ubuntu 16.04 x64 but I have a couple of bugs that screw up my Linux experience (haha). Like black screen at boot, no battery status icon, and so on. It's better to downgrade to Ubuntu 14?

Serg

now if i print hex values to 1 to 7 it prints 11 , 21, 31, 41 and so on . . .so MSB gets set correctly

i am so confuzed

TheXed

Don't you know that the newest version of Minesweeper takes 40 TBs?

Mateo

@Serg does any of this make sense: forum.arduino.cc/index.php?topic=44444.0 just googled some relavant words

Nathan Osman

@WilliamsAbrahamPerezCrazut It might be a better idea to downgrade. Quite a few things have changed in 16.04. Do you have an AMD graphics card?

@TheXed That's gonna take a hefty RAID array.

TheXed

01:49

Yeah Minesweeper doesn't mess around...

Serg

@Mateo reading

Williams Abraham Perez Crazut

No, I'm a noob here, have a Intel Integrated Grafics Card

Nathan Osman

(I'm waiting for someone to point out that "RAID array" is redundant.)

@WilliamsAbrahamPerezCrazut Hmm... the black screen issue is a bit strange then. I don't often hear of those on Intel graphics.

Videonauth

@WilliamsAbrahamPerezCrazut i would go at least for the next 3 months for 15.10, this was rock stable

Nathan Osman

Oh wait - do you mean it is black during boot but everything works fine afterwards?

TheXed

01:51

@NathanOsman it depends on the how the RAID is configured....

Williams Abraham Perez Crazut

No, after grub the laptop looks like suspended, but there's nothing on screen. I have to press power button to continue with the boot and then appears the desktop.

TheXed

@NathanOsman it could be RAID 0

Mateo

@Serg good thing you have a usb one, I had a touchscreen computer that had the screen attached to ttys6 :/

Williams Abraham Perez Crazut

Which version do you recommend?

Serg

@Mateo I've got a board that can use either usb or rs232

and none of those things did the trick by the way

:( I'm out of my wits for today

I've tried changing anything and everything

user139252

just cant remember who asked this

TheXed

@TheBrownOne right...

02:31

@Videonauth I answered one of those. My answer: You don't. You either use tar archives, and wget those and extract, or scp/rsync.

A: how to make file keeps it's permissions even it got copied

A pure combination of webserver + wget cannot do this. You'll have to try other options. You can: Provide a tar archive of the file On the server: tar cf puppetconf.sh.tar puppetconf.sh On the client: wget 10.1.5.128/puppetconf.sh.tar -O - | tar x Use scp/rsync to copy the file You will...

@muru no it was somone who wanted to make a repo of scripts he wrote for AU

and he wanted the files to run out of the box

Q: Download executable script from GitHub preserving +x permissions

I want to make a GitHub repository of all relevant scripts I posted here as answers. But to keep it ultimately simple for the users, I would like to give them a single command to download the script file from my repository directly, without having to install git first to git clone the entire rep...

permissions git wget curl github

Videonauth

wow howd you find this so fast ?

Third result (and the date helped)

Videonauth

ah ok i was trying the site internal search which isnt quite helpfull

just had a heureka moment for a solution

@Videonauth you did see @kos and my comments below the question?

Videonauth

narf no, well sighs

if i ever see someone write that ubuntu has aprotection against forkbombs im gonna kill lol

just managed to kill my computer this way

Mateo

lol, everyone also says don't try it ;p

Videonauth

well i dont mind rebooting but i saw some peopple write that theres a protection in ubuntu

to prevent them

i.e. here

Mateo

possibally, but why launch a nuke even if you think you are in a bunker

Videonauth

A: Using a Fork Bomb to prevent interactive shell on root

It would not do anything as any modern linux distro, Ubuntu included, has been patched so this fork bomb will not work (unless you change the default security settings). Go ahead, run it ;) See: Fork bomb protection not working : Amount of processes not limited http://superuser.com/questions/...

to test its integrity :)

i should have done that test in a vm

but ok so i have a freshly started laptop

it was anyways running since about 5 days

Mateo

02:56

Well, still could fry the processor

Videonauth

na that cant happen

far before the modern boards would shutdown

believe me i seen that here already with a clogged airflow on the laptop

it simply shut down from alone as it turned to hot

Mateo

Happens all the time, fan speed could be detected wrong

Videonauth

its not about fan speed its about temperature detectors directly inside the cpu

and if they would fail the cpu wont even startup

Mateo

ubuntuforums.org/…

anway, lets just agree that running it hot constant is a bad thing

Even if you don't see immediate effect, or it protected you that time

Videonauth

yeah its not something id advise to do constantly i had it run twice like that till i decided its time to take the laptop apart and clean the airpipes

since then no problems anymore :)

but i have to day i have set the temperature when it has to shutdown in bios to about 25% lower than default

default for cpu was around 90° C and its now set to 75°C

silizium melts at 128°C so it should be very safe

Serg

@muru askubuntu.com/a/762164/295286

@Videonauth

Not sure why you deleted your answer , but the idea was alright

except it's python, not sh

Videonauth

well it doesnt matter if the python script has the right shebangs

Nathan Osman

@Mateo @RPiAwesomeness This has got to be the greatest song ever.

Serg

Sort of does matter . . . there's difference between python3 and 2.7

Videonauth

sh works in this case only as interpreter

yeah thats right but then you can aswell have the shebang say python3

muru

If you tell sh or python3 to read commands from a file, the shebang is just a comment.

Videonauth

well doesnt matter i deleted my answer
