WHOA. I have close votes and flags again!!

I know what I'm doing tonight.

(can't tomorrow, i'm busy)

tomorrow, i got school.

What time UTC would work for another marathon for you then?

same time like earlier today for you?

1:59 AM

its 10AM your time, 2AM UTC right now

What time was it earlier? That time is good enough for me.

Nope, that won't work for me. I've gotta leave almost an hour before we started.

Well then, we can do it tomorrow!

Or now.

Now works. digs up that query

"I want to become a power user, where do I begin. Which free documentation is available to me."

basically I need a list of keyboard shortcuts... how to optimize a multi-desktop environment... how to utilize apt package manager.. ect..

I personally think a solid list of reference guides on these areas would be useful to myself, but I am trying to push some family members to try out ubuntu and they're only complains so far is that they do not know how to use its features and functions... which is to say; they (like me) has lived a life trapped behind windows, and the mystical beast which is linux intimidates.

anyways... night all (hopefully someone reads this whilst I slumber)

hmm what are you doing?

does Ubuntu use init scripts?

What changes does Unity's HUD offer http://askubuntu.com/questions/98285/what-changes-does-unitys-hud-offer #hud

I got my answer here help.ubuntu.com/community/UbuntuBootupHowto

@Joset I believe so, though quite a few applications have switched to upstart.

How do I use Unity-3d in a virtual box? :S

Do you have 3D acceleration enabled?

5:32 AM

For Virtual box? I am not sure.

@GeorgeEdison, yes, the only thing the traditional init scripts do is to call upstart. Thanks George.

OK that option is greyed out.

@jokerdino How much video memory do you have assigned to the machine?

That option is greyed out. Meaning I can't select it..

12 MB

you can't change it if your maching is running is it?

I have shut it down and now I can select it.

Right.

If your machine is running, you can't change it.

You'll have to shut it down (not just save its state) and then change the setting.

5:35 AM

Thanks. :)

BUT...

A word of caution... Unity3D is incredibly slow in VirtualBox.

yes? :S

Ah.

I use Unity2D and it's the difference between night and day.

wow. good luck to me then

It should still work, it will just be very slow.

5:41 AM

i just see a black screen :/

I see the lightdm now.

See - it's slow :)

It's very slow. I have now disabled 3d acceleration.

:)

Ah much better.

I have now shut down the virtual box.

My laptop fans are crying.

I take it your CPU doesn't have hardware virtualization?

5:53 AM

I have no idea about that. I am guessing that is the case.

You can check by going to the machine's settings and looking for a hardware acceleration checkbox.

If it is greyed out, you don't have it.

Where do I look that up?

In virtual box?

Yes.

It's under system settings, IIRC.

Both of them are ticked.

Enable VT-x/AMD-v and Enable nested paging

Hmm... then maybe you do have hardware virtualization.

It must be your video card that's causing the slowdown.

6:04 AM

I think I don't have any video card.

That would explain it then.

6:24 AM

@jokerdino: You might be interested in this.

Oh my. what game is that?

@GeorgeEdison, that's a cool one

@jokerdino TrackMania Nations Forever.

@Joset Thank you.

I am now downloading the installer.

:)

6:54 AM

It's time for you to say good night. :P

LOL!!

I was literally about to say that :)

So... good night then.

good night @GeorgeEdison

You can try running unity --replace

any ideas why my unity borked out like that...

or how to fix it without rebooting?

You did a unity --replace?

yup

@jrg I know the SO PHP room uses " pl-cls link-to-question " format, then you can just search the chat for pl-cls i guess and you have your archived list

nvm... you can search for "pl-cls" but not pl-cls

@jokerdino 3d

I was in 3d, want to switch to 2d whilst logged.

I don't think that is possible right now.

1:30 PM

if you read some of the other 'questions' related to mine and the 'answers' posted, the posters claim their solutions work... i dunno.

@AmithKK What's wrong with that?

and re: the posted question, not quite like that.. i'll see if i can get a pic of what happens.

ok so i think i've got the 'figured out how to restart unity' answered

CTRL+ALT+F1
login....
"unity"
CTRL+ALT+F7

so far no problems....

so no problems?

this is what i see after running unity --replace

here is the console dump

paste.ubuntu.com/816423

i think all of those WARN's are when I took a screenie

ignore the warnings. i get them when i setsid unity as well.

1:39 PM

but you can see in the terminal there I currently have 'unity' running - soo CTRL+C gives me back the terminal window but kills unity

setsid unity

good luck.

what does setsid do?

run a program in a new session.

ahhh... so it wont take over that terminal session

yeah kinda

1:41 PM

would say...sudo setsid gedit /path/to/rootonly/file open gedit as root but keep my terminal window free

i don't know about that.

i only used it for unity.

DISCLAIMER: don't take my advice for granted.

my global menu is gone

not in chrome but in gimp at least

wtf

LOL

you opened gedit?

reboot!!!

that is what i'm talking about with the 'keeping the terminal locked'

@jokerdino lol.. i will i will. :P i'm trying to learn more about the system and how to fix these things without just rebooting..

why dont you open a new tab?

Ctrl + shift + T

1:47 PM

i want to become "power user" ... i get annoyed at myself because I knew windows inside and out.. Linux (And specifically ubuntu) is a foreign beast.

if you don't want to reboot, you can just restart X...

sudo service lightdm restart

@jokerdino blushes i did not know the terminal supported tabs.

that will log you out

you have to bare with me... never used linux or any x-windows based systems, also have only been on ubuntu for ~60 days.

i totally understand you.

i only started using linux / ubuntu last year.

1:49 PM

I apologize if my questions seem remedial .. i do promise you all I am absorbing it all and learning quite a bit... but there is still so much more to go.

don't need to apologize :D

you can use multiple windows in terminal as well.

and set titles to each window / tab in terminal

i've been trying to find vids on 'power user guides' (after watching the one by jeorge on SCaLE site)

hmm power user videos? O.O

FYI, jrg is the leader of Ubuntu power users community. You should be nagging him.

when I type it does nothing :(

It doesn't like me cause I'm an alien D:!

you should be on firefox, that's why!

2:35 PM

I am on Firefox

AHA!

it was one package that didn't get upgraded (should have been a dependency)

guis!! I am trying to install the new HUD on 11.10

more like discrepancy

@rlemon You can't do that.. :p

but you can hack it in

:P

strange, it doesn't show the close tab option in HUD in Firefox

so basically I tried hacking it in.. but now I cannot remove it. :P

paste.ubuntu.com/816487

2:45 PM

Good luck :p

how come I cannot change the distribution in "Software Sources"

i change it to 'precise' but when I click ok it just reverts back to 'oneiric'

not sure about that..

solution if anyone is interested was going to /etc/apt/sources.list.d/ directly and editing the unity-team-hud-oneiric.list file contents then renaming it to unity-team-hud-precise.list

then running sudo ppa-purge ppa:unity-team/hud works.

so you installed hud or removed it?

this is also the 'hack' to put hud on the system.

2:57 PM

oh removed it.

now I can install and remove it.

it's buggy as hell on 11.10 but you can see it.

now that I am confident I can remove it i might play around a bit more with it.

you should rather get it on 12.04 :P

I know... I just haven't gotten around to setting up a 12.04 system or VM

... Anyone know the Linux way of doing netstat /n ... basically want to see what ports are currently open

4:30 PM

@WilliamHilsum nmap -sS -O 127.0.0.1

or

sudo netstat -nap

Doesn't Nmap basically do a local scan through ports rather than an actual network level detection of what is open?

sudo netstat -lnptu

i guess that's what you want?

yeah, that's exactly what I wanted! great, thanks!

yw :)

didn't know netstat was a linux command! doh

netstat - Print network connections, routing tables, interface statistics, masquerade connections, and multicast memberships

4:35 PM

Netstat prints information about the Linux networking subsystem. The type of information printed is controlled by the first argument, as follows: (none) By default, netstat displays a list of open sockets. If you don't specify any address families, then the active sockets of all configured address families will be printed. --route , -r Display the kernel routing tables. See the description in route(8) for details. netstat -r and route -e produce the same output. --groups , -g Display multicast group membership information for IPv4 and IPv6. --interfaces, -i Display a table of all network interfaces. --masquerade , -M Display a list of masqueraded connections. --statistics , -s Display summary statistics for each protocol.

oh, chat does ubuntu manpages? :-o

It is somewhat well stable and also you can run it without risks in 11.10. In case something goes wrong, use the command ppa-purge to revert back.
