Q: I need help booting in to GRUB. 13.04

I need help booting in to grub in 13.10. I cant get to grub. I didn't exactly install Ubuntu. It was preinstalled for my specific pc (its a smart book from Taiwan) and I copied it to my SD card (because it only boots from SDcard by default) and when I press shift, nothing happens it just goes int...

Hello, I am not sure why nohup doesn't save a process from its parent shell process terminating?

Q: Why is chromium-browser killed when I close the terminal despite nohup?

This question is old, and I am still not clear about why. In a Gnome Terminal tab, I ran $ nohup chromium-browser & But when I close the terminal tab, chromium-browser also exits. Isn't nohup supposed to prevent that? Gilles said: nohup and disown both can be said to suppress SIGHUP, but ...

chrome nohup

This is one of the better forum comments I've read:

> "I got it all back to gether okay, but now I have to figure out where the printhead possision sensor is, as I keep getting a print head jammed error afer the print head trys to slam itself through the right side of the printer. *Sigh"

> - Source

There's something funny about trying to picture the printhead slamming itself repeatedly against the side of the printer.

Seth

@Mateo ok, so I see it got called 3 times.

That's not supposed to happen.

What kernel version do you have?

Mateo

3.16.0-33-generic

Seth

12:11 AM

huh, actually newer than me.

Mateo

oh, and I just installed virturalbox kernel headers...

hm....

Seth

lemme see if I'm behind and can reproduce.

huh, no kernel update.

@Mateo You on 15.04?

Mateo

14.10

Seth

same..

I wonder why you have a newer kernel.

Mateo

what version are you on?

Seth

12:17 AM

3.16.0-31-generic.

major typo there ;P

@Mateo Can you add a line to the script echo "1" >> /home/Mateo/Documents/testing.logto the bottom of the script? I'm pretty sure the event is being called 3 times but best be sure.

Then plug it in and see how many 1s you get in the file.

Mateo

oh, check this out -

paste.ubuntu.com/10721427

Seth

@Mateo That's one unplug and then one plug back in?

Nathan Osman

This is a bad sign:

Seems to be common.

Seth

@NathanOsman indeed. Welcome to the wonderful world of HP Printers.

Mateo

the three ac events?

Seth

12:23 AM

@Mateo There's actually 4.

I'm guessing 1 for remove and 3 for plug in.

Nathan Osman

@Seth I've had it up to here with HP printers.

Actually, I've had it up to here with printers :P

Seth

There's a reason I use Epson ;)

joshumax

@Mateo what does running udevadm monitor --environment --udev show when you remove the AC adapter?

Seth

2 mins ago, by Mateo

http://paste.ubuntu.com/10721427/

Nathan Osman

@Seth Thanks for the recommendation. They may just have a new customer.

joshumax

12:24 AM

@Seth Thanks

Seth

The only problem is their ink has gotten a good deal more expensive of late..

Nathan Osman

Do they still work if you refill them yourself?

Seth

@Mateo So, looks like the event is indeed being triggered 3 times when you plug in..

Nathan Osman

Or is it like HP where the printer yells and screams when you insert a "non-genuine" cartridge?

Seth

@NathanOsman Haven't tried, but I really do not recommend doing that.

Mateo

12:25 AM

well, I got to go

Nathan Osman

I've never refilled a cartridge, just curious.

joshumax

@Mateo Wait

Nathan Osman

Which is why I get frustrated by HP - we've always bought genuine cartridges and it still breaks down... right after the warranty ends too :(

joshumax

It does the same thing on mine

(not the popping up three times, but it shows the same output from udevadm)

Seth

@NathanOsman Almost positive this will happen, but I have no references other than most cartridge manufacturers embed a special chip into the cartridge..

Nathan Osman

12:27 AM

Yet another case of DRM :P

Seth

huh @joshumax @Mateo, I only get two AC events as expected.

@NathanOsman yep.. Can't say I blame them exactly buuuut... yeah.

joshumax

I get 18

Seth

o_O

joshumax

But I only get two from AC0

Seth

well I was already working on a dbus solution that doesn't require an infinite loop in bash.. I guess I'll just work harder?

joshumax

12:29 AM

Which should only come up twice

Seth

Or we could look into a few other udev flags.

Nathan Osman

@Seth Well, I have no problem with them saying "your warranty is invalid" if I use non-genuine cartridges. They just had better not prevent me from installing and trying to use them.

Seth

but this method doesn't seem to be as reliable as I had hoped.

joshumax

I'd need to see @Mateo's result from udevadm with the --environment flag set then

Mateo

ok here it is @Seth

paste.ubuntu.com/10721459

joshumax

12:29 AM

As if on cue

Seth

Thanks @Mateo! I guess we'll catch you later?

Journeyman Geek

@Seth: IIRC canon can be refilled but won't keep track fo how much ink you have.

Mateo

here and there...

joshumax

strange, three POWER_SUPPLY_ONLINE=1's

Seth

@JourneymanGeek Interesting. If I didn't get an Epson I'd probably get a Canon.. although HP just reuses Canon parts usually.

Journeyman Geek

12:31 AM

Dell (which resells lexmark or samsung iirc) makes you clock through 3 menus, and tells you your warranty is void.

@Seth: well, the older canon we had just worked ;p

Seth

Actually, I'd prefer a Brother, but they don't make many small printers and I am unsure about their linux support.

@JourneymanGeek older == better :D

Journeyman Geek

thinks we switch printers every 4-5 years ;p

and maybe 2 carts in that time per colour, not counting refills

Local ink store does sell a modded, CIS epson IIRC

Nathan Osman

Let's crowdfund a printer. It'll be compatible with Linux out-of-the-box, have easily-serviceable parts, and last for a good long time.

joshumax

Okay great

Nathan Osman

Amirite?

Seth

12:32 AM

Along with 3 ACTION="change" @joshumax.

joshumax

I found something else to compare against

Look at the bottom of this diff -- diffchecker.com/kdfozz1p

POWER_SUPPLY_STATUS=Charging vs POWER_SUPPLY_STATUS=Unknown

When do you want the notification popping up?

Seth

Doesn't really matter within the time frame we're discussing IMO.

Mateo

just once on plugging in the ac adapter...

joshumax

Ah, yes

The problem was my original udev script was for unplugging the adapter

s/script/rule/

Mateo

it does that one fine ;)

Seth

12:35 AM

I'm still not having any issues :P

joshumax

Here, I'll make a new one real quick

Seth

I'm going to (hopefully) replace all this with a python script.. but I still haven't figured it all out yet.

Mateo

maybe just a strange quark of the hardware...

joshumax

Hmm

Actually, it seems that POWER_SUPPLY_STATUS isn't very trustable

I can't actually find anything to discern between the triggers

Seth

yeah I was thinking the same thing.

joshumax

12:41 AM

hmm

Let me think...

Mateo

would have to write some kind of catch?

like only show once for so many hits on a change within 20 sec?

joshumax

does adding OPTIONS+="last_rule" help at all?

Mateo

dosn't look like it, but I could be doing it wrong

joshumax

lemme try it

Fixed it for me

Your udev rules?

Mateo

deleted ;p

joshumax

12:48 AM

can you paste them?

Mateo

where did you put the options at in the rule?

joshumax

After the ENV and before the RUN

Works consistently on my end

Mateo

I'll give it a go

joshumax

@Seth, if this works can I update your answer?

Seth

@joshumax Go for it.

joshumax

1:07 AM

@Mateo Any news on if it works?

hbdgaf

1:19 AM

@NathanOsman - I think your ping logic is broken.

Nathan Osman

Huh?

Oh!

hbdgaf

look at flackbot. he's floundering around with the numbers.

Nathan Osman

I didn't see him replying in this room!

I was testing him in the Sandbox.

My bad. Sorry.

hbdgaf

it's okay. was just letting you know

Mateo

@joshumax nah :/

hbdgaf

1:26 AM

@Mateo - I tell you I actually tried that food? Totally delicious.

Not so good as leftovers though. Grilled cabbage as a part of a food gets really disgusting when you let it sit for a day. totally takes over the whole plate.

Mateo

hm? play on words?

hbdgaf

no, i was totally serious.

Mateo

I guess I forgot something then...

:/

was it the egg dish I linked awhile back?

hbdgaf

no it was something like this

norecipes.com/recipe/okonomiyaki-recipe

think egg, protein, cabbage, crepe, and suped up ketchup + mayo as a sauce on top

Mateo

oh, that reminded me of crab cakes, looks good with the bacon

hbdgaf

1:32 AM

yeah, i totally used bacon.

didn't pair well with busch ice, but it was good food.

Mateo

maybe something more like tecate or Franziskaner Hefe-Weissbier

hbdgaf

with it to do again, i would probably choose something sweet. like a newcastle.

Mateo

awesome logo:

hbdgaf

Nice. I think if you disagree with that you're either drinking the wrong beer, eating the wrong food, or both.

RPi Awesomeness

@ByteCommander Not sure if being mean and showing off your amazeballs internet, or if you legitimately think that's bad. 'cause 1GB would take somewhere upwards of 3-4 hours on my internet.

Whoa.... Flackbot has dat fancy new logo!

hbdgaf

1:47 AM

@RPiAwesomeness just said amazeballs.

RPi Awesomeness

@hbdgaf o.O I did....yes

Is that an issue?

hbdgaf

no, i just found it amusing.

RPi Awesomeness

Okay :)

Seth

ok, internet speed warz going on? We'll just call in @jrg and that'll silence everybody ;p

hbdgaf

well we can't all live in a datacenter...

RPi Awesomeness

1:54 AM

@Seth I take it he has the super amazingness over-9000 internet speedz?

Seth

See @hbdgaf's comment above ;)

@hbdgaf made me smile, have a star.

hbdgaf

think fiber to home * 2, and you're almost there.

Seth

maaan, fiber is coming in like 20 miles away from me :(

I can't complain about my internet other than it's outrageously over priced..

hbdgaf

well, living in a camper, i could just back the truck up to where the internet feeds are. so...

just sayin'

Nathan Osman

@Seth If yours is overpriced, think of how bad mine must be.

30mbps for $70/m

Mateo

2:03 AM

which is about 55 of our $

Nathan Osman

Or $50/m for 5mbps, which is a worse deal, IMHO.

Mateo

woah, that is quite a jump

RPi Awesomeness

@NathanOsman Brah. $70 a month for 30 mbps? That's like, pocket change compared to what we could get for that around here. For $70 month you can get, like 3-5 mbps maybe.

Nathan Osman

@Mateo $55.49, not bad. Good guess.

RPi Awesomeness

That's being generous :P

Oh wait. Canadians.

Nathan Osman

2:04 AM

@RPiAwesomeness Wut.

That's practically robbery.

RPi Awesomeness

That's actually friggin amazing. $50 for 30 mbps. I'm movin to Canada.

Nathan Osman

Waits for @Rinzwind to say something about $10 Internet...

RPi Awesomeness

@NathanOsman Indeed :P

Seth

@NathanOsman I get phone and 20Mbps internet for $70 a month (US)

RPi Awesomeness

@Seth if @Rinzwind so much as peeps about his amazing European ISP, he is to be ban hammered. Okay?

Nathan Osman

2:05 AM

That's roughly our home phone + Internet bill except we get 1mbps.

@RPiAwesomeness Agreed.

Seth

oh I didn't say I got 20Mbps.

Nathan Osman

Oh...

Seth

I said I paid for 20Mbps ;)

Nathan Osman

When services get bundled, it's hard to figure out the cost of each individual utility.

RPi Awesomeness

@NathanOsman Yeah. From one provider (granted, its local and a fairly recent startup) you can get 3-5 Mbps for $80/month. I have yet to look at Comcast.

Nathan Osman

2:06 AM

Ouch. Ouch. Ouch.

Seth

@NathanOsman That's where it gets really bad.. If we took phone off of our bill it'd still be $60/70 bucks a month.

RPi Awesomeness

Best we can get from AT&T is 1.5 Mbps down for ~$40-$50 IIRC.

Seth

I'm getting 17 download right now which is fairly normal.

RPi Awesomeness

I gave up on them a while back

Seth

Practically never get 20.

Mateo

2:07 AM

must be out there in the woods somewhere ;)

Seth

The next step down on the scale is ~$50 for 2Mbps.

RPi Awesomeness

@Mateo That's just it. We're ~5 minutes from a decently big town.

Nathan Osman

So far we've also been lucky in that the company hasn't forced us to use their router. They just give us a really dirt-cheap modem that I plug into this bad boy‌.

RPi Awesomeness

Funny thing is, AT&T keep sending us these letters trying to get us to upgrade and they include some form of "bonus" for doing so. However, there's two problems.

Nathan Osman

I suppose if they did send us one I could just disable the wireless radios and set up another router as a DMZ.

@RPiAwesomeness (1) they're a bad company (2) they don't offer better service.

RPi Awesomeness

2:09 AM

#1 We can't even get their Cable internet near us. #2 The deals have got worse every single letter we've got (at least 1 per month for the ~6-8 months)

@NathanOsman ikr. I've heard Comcast is worse though

Seth

@NathanOsman What were you saying your ping to Germany was?

Nathan Osman

Lemme check.

Seth

@RPiAwesomeness I'd say 9/10 chances ;)

that'd be your router/modem no @NathanOsman?

Nathan Osman

Sorry, I meant the next one.

The 192.168.1.1 is my router.

From here to 10.31.250.1 is 35ms - I'm guessing that's my ISP's network gear.

So your packets are taking a completely different route. And a shorter one at that.

(Shorter by number of hops.)

It's kind of fun to try and guess which of those is the trans-Atlantic hop.

Seth

@hbdgaf can't say, but you'll notice the URL's change from .us to .de on 10-11.

@RPiAwesomeness Part of it might be that you're closer to the east coast than we are, but that's pretty cool.

hbdgaf

8-9 and 10-11 are both much more expensive than the rest of them for sure though...

Yeah, that's probably it.

I'm making the same guess but no one else's output has it so it is kinda weird.

I get that too when I try it from a server in Dallas.

huh, nope.

woah what would cause gdm to display over lightdm where you have to unlock twice...

Nathan Osman

Heh. Oh well. I added an extra 5 GB of premium data to my phone plan, so I get 10 GB per month before they slow it down now.

It sounds better than it is - I get about 1-2mbps during the day.

Overnight, when few people are using the network, I've got as high as 8mbps.

@Mateo Unlock-ception.

@Mateo o.O

Mateo

so, I turned off unity's lock screen, and the gnome one is still there, something pulled in a dependency i guess...

@Mateo huh, I had that happen to me today too.

Mateo

strange...

Actually it started a few days ago I think..

there it is

something installed "gnome-screensaver"

uninstalled and done ;)

Seth

that's a default package @Mateo..

hmm.

Hi @Mitch!

huh

gdm isn't actually installed..

So what was that?

ohhh.. I guess it could be gnome-screensaver misbehaving.

Nathan Osman

I used to have a different issue with the GDM lockscreen - it constantly lost keyboard focus.

My password would get typed into the window beneath the lockscreen.

Seth

That's.. bad.

Nathan Osman

Uh-huh.

LightDM hasn't done that to me, though it doesn't play nice with Synergy when the cursor is on the other screen.

Hello

Nathan Osman

3:23 AM

Whoah... why is there only 3 GB left on /home...

Hrm... why is my Win7 VM taking up 14.9 GB...

Time to move the VMs to my other hard disk.

Seth

@NathanOsman Think you could answer a question about dbus for me?

I'm trying to listen for a signal in python.

Nathan Osman

I can try.

I recently tried to do something in Python with D-Bus. Let me see if I can find what I wrote.

Seth

The api says add_signal_reciever() take an argument signal_name:, the thing is I'm not sure what the signal name is. I know the interface and path it will come from though..

Nathan Osman

One thing that will prove to be very helpful when working with D-Bus is a tool named d-feet.

It lets you browse the current interfaces on both the system and session bus.

Seth

cool, I'll check it out.

I was using dbus-monitor to get the information I do have, but it doesn't have a signal name.. Unless the name is a piece that I just don't recognize ;p

Nathan Osman

3:37 AM

I'll see if I can find an example.

There's an example from Sublime 3.

Seth

ok.

I think I found what I'm looking for. Apparently the signal is in the member= part of the signal..

Nathan Osman

I'm assuming the signal name is "FileClosed" in that example.

Seth

Lemme see if I can get a test version running. Thanks @NathanOsman!

d-feet looks super userful :)

Nathan Osman

No problem.

Seth

3:57 AM

@NathanOsman If you're on a laptop can you do one last thing for me? In /sys/class/power_supply is there an AC or ACAD folder?

Nathan Osman

Sorry, I'm on a desktop.

:(

Seth

That's ok! I'll go ask in IRC then :)

now that is weird.

ohhhh

Mitch

@Seth

Seth

huh.

what's up @Mitch?

Mitch

Seth

4:06 AM

@Mitch ah cool. Thanks!

That's very helpful.

I wonder why mine just has an AC folder..

@NathanOsman 18 mbit for 15 euro but for that price you also need to take up TV and Phone in a 3 in 1 deal.

(where TV is 30 euro and Phone 10 euro a month)

Hi, everybody

I compared the speed of enlightenment & compiz & mutter.

As result, enlightenment is the fastest.

I could not understand it.

why? Who knows about it?

Oli

8:31 AM

@xiaodongjie Speed? Doing what?

xiaodongjie

speed!

Oli

I understand the word, I just don't understand what it is you've been comparing between the desktop environments... How long it takes to load? How fast menus and effects feel? Something else?

Danatela

hi guys!

does anybody know how to turn on autoscrolling for chat? It turned off occasionally

Oli

@xiaodongjie Either way, it's probably because the Enlightenment desktop started in the 90s and has always put as much focus on code quality and speed as looking good. Compiz and Mutter both require heavier graphics engines to achieve their looks which take time to load. And they're far less mature projects.

xiaodongjie

yes. i think so

Anyone here updated to Firefox 37? I think I found a minor bug, want to see if anyone can reproduce

When using YouTube HTML5 player, a black box occasionally appears on top of the player timeline, covering parts of it such as the pause button

Firefox 37 bug on YouTube HTML5 Player (Ubuntu)

►

Oli

@ace I think it's probably flickering rather than a black box being rendered over the top, but yes, I see the same here in FF37.0

It seems (complete guess) to be related to the buffer progress. The length of the box over the progress bar expands a lot faster than the progress and doesn't flicker at all near the end (when it's completely loaded).

I don't get any flickering from my Watch Later queue.

ace

@Oli I wonder if I should file a bug report, and if yes, where

Oli

@Danatela Why? (I'm open to suggestions - but I can see "Ubuntu" several times which usually makes something on-topic)

Danatela

@Oli with all my respect, but did you read it carefully?

Oli

@Danatela Not at all

Danatela

It's about POST keyboard check

and speaking POST I mean Power-On Self Test

Oli

@Danatela Something in the very corner of my mind feels like there's been a legitimate issue with the Linux kernel not leaving keyboards in a safe state at shutdown.

But that might have all been a dream.

Here is something similar: superuser.com/questions/727950/…

Which links back to one of ours (where I probably read it) askubuntu.com/questions/410596/…

Danatela

9:40 AM

@Oli may be. But it's not the issue. I usually try to exclude simpliest things first. For example, I will not dig into pulseaudio settings if my speakers are not plugged to the sound card's out.

Oli

10:12 AM

@Danatela Having-re-read it (some could argue I'm only reading it for the first time), yeah, that looks like a very silly question. I thought a keyboard was plugged in but now see the significance of Synergy.
