Compiz running ...but not "running"

chadefa1 · 11-17-2007, 06:01 PM

I'm puzzled: I have compiz installed, and it used to work perfectly: the cube, compizconfig... perfect.

But then I rebooted, and it stopped working. I tried to de-install and reinstall it, but to no avail.

If I click on compizconfig, the computer seems to be looking for something (a crrr noise), but nothing happens.

Here is the output in my console (note that compiz appears when I ps, at the end):

This is a guess if using ATI. Post output of the following commands.
uname -r
fglrxinfo

... or the nvidia driver didn't load

Did you do a kernel update or anything significant before the reboot?

Which distribution are you using?

You may have to reinstall the nvidia drivers. If you have a nvidia graphics card, of course.

Thanks for the help!
I am running Ubuntu 7.10, sorry for not specifying it.

All I did before this mess happen was follow the instructions of this guy:
http://ubuntuforums.org/showthread.php?t=470160

Since then, I have reverted the file to its original status.

As for Brian's questions:

thomas@ubuntu:~/Documents/Latex$ uname -r
2.6.22-14-generic
thomas@ubuntu:~/Documents/Latex$ fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: Tungsten Graphics, Inc
OpenGL renderer string: Mesa DRI Intel(R) 915GM 20061017 x86/MMX/SSE2
OpenGL version string: 1.3 Mesa 7.0.1

Thanks for helping me. Compiz is not necessary, but it sure is fun and will help convince many to switch to Linux...

looks like using the Mesa which is not what you want. What is in your xorg.conf file?

I assume this is the relevant section?

Section "Device"
Identifier "Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller"
Driver "intel"
BusID "PCI:0:2:0"
EndSection

Actually there should be a section for loading modules and DRI is one of them.

I don't have an Intel or have used one but in my xorg.conf I have a section like this.

Code:

Section "Module"
	Load  "dri"
	Load  "extmod"
	Load  "dbe"
	Load  "glx"
EndSection

I would make a backup of your current xorg.conf file and add the changes. If something goes wrong you can easily restore the saved file back from a runlevel 3 mode.
