compiz stopped working

[AndyOsi]

Binary package hint: compiz

I'm using a Thinkpad Z61T with integrated Intel i945 graphics card. Two days ago compiz effects stopped working on my machine for no apparent reason. When I attempt to enable them on the 'Appearance' menu, an error message pops up saying that desktop effects could not be started.

Starting compiz from the CLI reports:

Checking for Xgl: not present.
Detected PCI ID for VGA:
Checking for texture_from_pixmap: not present.
Trying again with indirect rendering:

Please note that previous to this compiz had never had any sort of issue.

Update: Problem was resolved by removing the "Virtual" section on Xorg.conf. Nontheless a regular user who had no idea about this file wouldn't have known about this. The "Virtual" section was added when I attached another monitor and extended my desktop with it.

Could a feature request be included for Desktop Effects so that the user may know when the virtual resolution of a desktop is too large to be supported by the video card?

Thank you for taking the time to report this bug and help make Ubuntu better. Please attach your /var/log/Xorg.0.log, /etc/X11/xorg.conf and ~/.xsession-errors to this bug report after attempting to enable desktop effects.

Thanks in advance

I'm attaching the requested files.

I am having similar problems on an msiwind with compiz returning same complaints up to

Software rasterizer detected, abortingaborting and using fallback: /usr/bin/metacity

I used an extra monitor yesterday and everything was working fine so it is not a graphics card issue. Any ideas? I think there was only one update since yesterday and I didn't think it was anything important.

mathtick - please provide the information that AndyOsi provided earlier

Attached is an archive of the three files:

It seems that things are working after today's updates (which I just ran).

So apparently running "compiz --replace" or "compiz" in the terminal is not same as enabling desktop effects in the gui?

Some of my settings were lost (I had to reenable various options) but it looks like it's working.

oh, well. I guess I should learn to wait at least a day before hitting launchpad when compiz breaks :).
