For example:

$ cd ~/code/someFolder
~/code/someFolder$ gitk --all& # launches a gtk window of gitk
[1] 9335 # what is this in the first place

now I go do some work inside the gtk window, then close it

~/code/someFolder$ echo 'foobar'
foobar
[1]+  Done                    gitk --all # this extra output

I have an inkling that the ampersand is somehow 'holding' the process and closing it in gtk ends the process resulting in the output... but that's a very unscientific explanation.

PS: Sorry about the unwieldy question, I couldn't think of a better way to express it.

I was trying to run yeoman under my user, when I got errors when it tried to access /home/adityamenon/tmp. I checked the permissions and it turns out ~/tmp/ belongs to root.

So I changed the user and group to myself, but was this the right thing to do? Who should ~/tmp belong to?

Also, when I'm booting, I get an error message about /tmp/ not being mounted... if that info helps.

I ran:

%> sudo add-apt-repository ppa:chris-lea/zeromq
%> sudo aptitude update
%> sudo aptitude install zeromq3 php-zeromq # result: zeromq3 - no such package found

I tried restarting my system, running sudo apt-get update, restarting again, but in all cases I get the same package not found result.

I have verified that these packages exist for 12.04 by filtering for Precise from the "Published in:" dropdown at the Launchpad.net page.

What do?

12.04

I installed Bumblebee following the instructions on the wiki: https://wiki.ubuntu.com/Bumblebee#Installation

It is working! I checked out glxspheres and then optirun glxspheres, and I got 55fps and 133fps respectively. Hot.

I also got the "Unity 3D" Ubuntu interface working after I installed Bumblebee. However, here's the output of /usr/lib/nux/unity_support_test -p:

adityamenon@jaguar:~$ /usr/lib/nux/unity_support_test -p
OpenGL vendor string:   Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Mobile x86/MMX/SSE2
OpenGL version string:  3.0 Mesa 9.0.3

Not software rendered:    yes
Not blacklisted:          yes
GLX fbconfig:             yes
GLX texture from pixmap:  yes
GL npot or rect textures: yes
GL vertex program:        yes
GL fragment program:      yes
GL vertex buffer object:  yes
GL framebuffer object:    yes
GL version is 1.4+:       yes

Unity 3D supported:       yes

So it appears I'm still on the Intel card for my 3D-effects interface. I'm sure running on the nVidia card instead would make the experience faster... how do I do that?

This is my laptop: http://www.samsung.com/in/support/model/NP300V5A-S0CIN-techspecs

Pertinent specs being:

Processor    Intel® Core™ i7 Processor2670QM (2.20GHz, 6MB L3 Cache)    
Graphic Processor    NVIDIA® GeForce® GT 520MX Graphics, Optimus™ technology
Main Chipset     Intel HM65

EDIT: Just read this question from the sidebar: Can I set my Optimus Nvidia card to run Unity3D with bumblebee?

I didn't think of optirun /usr/lib/nux/unity_support_test -p... so I did that, and here's the output:

OpenGL vendor string:   NVIDIA Corporation
OpenGL renderer string: GeForce GT 520MX/PCIe/SSE2
OpenGL version string:  4.2.0 NVIDIA 304.88

Not software rendered:    yes
Not blacklisted:          yes
GLX fbconfig:             yes
GLX texture from pixmap:  no
GL npot or rect textures: yes
GL vertex program:        yes
GL fragment program:      yes
GL vertex buffer object:  yes
GL framebuffer object:    yes
GL version is 1.4+:       yes

Unity 3D supported:       no

So unfortunately, it says Unity 3D isn't supported on this... the answers on the other question only advise selling this laptop and buying a new one with discrete graphics :D Is there any other way?
