Compiz crashes in Ubuntu 12.04 official release

Asked by ursaminor on 2012-04-27

On fresh install, Ubuntu 12.04 ran Compiz alright. I ran the Update Manager, rebooted and Compiz was good. After installing Additional Drivers, i.e. Nvidia, Compiz crashed and nothing but wallpaper appears. Right-click on screen works and I clicked on Change Desktop Background, then All Settings. I went to Additional Drivers and uninstalled Nvidia. Rebooted and all is well again. Seems like a bug.

I have the same problem, which only arises when the proprietary nVidia drivers are installed. With the open-source nouveau drivers, the problem does not occur.

I am happy to supply additional information, such as hardware information/debug information/system logs if necessary.

Can you give the output of:

sudo lshw -C display; lsb_release -a; uname -a; dpkg -l | grep nvidia

Output of "sudo lshw -C display; lsb_release -a; uname -a; dpkg -l | grep nvidia" (bear in mind that I do not currently have the binary driver installed -- I am using nouveau):

Some extra information: with the binary driver installed and active, the lightdm login screen displays fine, but when I try to open an Ubuntu session, compiz throws an error as mentioned above. Also, when I try to open an XBMC session, I get only a blank screen, though the session is clearly working, since I can hear navigation sounds when I press the arrow keys and am able to exit the session using the normal menu options.

Question 195022 discusses the same problem


sudo dpkg -P nvidia-173
sudo apt-get --purge remove nvidia-cg-toolkit nvidia-settings nvidia-settings-updates
sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install nvidia-current

Then reboot

James Womack (james-c-womack) said : #7

Okay, I'll try that.

Further information: It seems to be specific to the 7050 integrated graphics chip. I tried a spare PCI express graphics card (Geforce 8400 GS) and the system functioned without the problems described above.

James Womack (james-c-womack) said : #8

The fix suggested by actionparsnip makes no difference. The system still runs fine on the PCI express GPU (Geforce 8400 GS) and has the same problems with the integrated GPU (Geforce 7050).

Bertalan Fodor (fodber) said : #9

Tried the suggestion on an nforce360a based motherboard with integrated geforce 7025. Compiz still crashes, so I can log in only with Unity 2d.

Bertalan Fodor (fodber) said : #10

This seems to be a problem with nvidia 295.40 driver.
You must downgrade to 295.33 or wait for the fix from nvidia.
It's a pity that ubuntu release went out with such a widespread issue.

mr. Ed (mred) said : #11

how can i doing the downgrade?

Bapf (bugs-ubuntu-bapf) said : #12

@mr. Ed

Download and install (or the corresponding 32bit package).

You then also may prevent ubuntu from updating it via apt-pinning.

Solved the problem for me.

Can you help with this problem?
