Compiz problems

[dave11980]

Got a bit of an odd problem I'm hoping you guys can help out with. I recently installed 9.04 and had it working wonderfully with full desktop effects enabled on two users, mine and my wifes. After about 2 days I am now only able to get it working on 1 user at a time, which ever user logs in first after reboot. The other user gets the desktop effects could not be enabled error. I've tried starting compiz from the cli as well and get the below output.

compiz cli output:
Checking for Xgl: not present.
xset q doesn't reveal the location of the log file. Using fallback /var/log/Xorg.0.log
Detected PCI ID for VGA:
Checking for texture_from_pixmap: not present.
Trying again with indirect rendering:

Checking for non power of two support: present.
Checking for Composite extension: present.
Checking screen 1Comparing resolution (1024x768) to maximum 3D texture size (2048): Passed.
Checking for Software Rasterizer: present.
Software rasterizer detected, abortingaborting and using fallback: /usr/bin/metacity



This is all running on a dell dimension 4700 with intel graphics.

I'm not sure I follow you there. Can you elaborate?

One thing I did find out on the tubes is that when a second X server is started on intel graphics cards it doesn't get DRI support. I indeed have two X servers running when both users are logged in.

root 2596 2593 3 14:18 tty7 00:00:22 /usr/bin/X :0 -br -audit 0 -auth /var/lib/gdm/:0.Xauth -nolisten tcp vt7
root 3847 3842 1 14:24 tty9 00:00:03 /usr/bin/X :20 -br -audit 0 -auth /var/lib/gdm/:20.Xauth -nolisten tcp vt9


I couldn't be certain without reinstalling but I am close to certain that this did work a week ago when I first installed and stopped working sometime a couple days later. I also read that the guest session starts a separate x server and that xnest does as well, both things i have done. I've uninstalled xnest but I think there may be some setting from either the guest session or from xnest that is lingering and forcing new users to spawn new xservers. Anyone have any ideas on this? Or am I full of crap? I am fairly new to 'desktop' Linux.

I did a full apt-get purge on all compiz packages, restarted computer, and then apt-get install. I'm still seeing the same problem.

From the other things I've been reading this has to do with intel drivers not providing DRI to any x servers after the first. I've confirmed in my /var/log/Xorg.20.log that the second xserver doesn't have DRI. The question now is this, is it possible to configure multiple users to share a single xserver instance in ubuntu 9.04, and how?

Im not an expert but i had a similar problem and what i did was start up in kernel mode (i think thats what its called) then i chose to "automatically fix display errors" (once again i think thats what it says or at least something similar) after that it worked fine as well as fixed my other problem with my Xorg.conf (i was editing it and i did something wrong, when i rebooted my display wasnt working all i got was a black screen = = )
