Lost a lot of graphics capability

A software change on my computer (I'm not sure what caused it) has caused me to lose a lot of graphics ability on my Compaq Presario C306US running Ubuntu 8.04 Hardy Heron.  Before, I could use the "Extra" setting in Visual Effects without suffering a performance hit but can now only use "None" to get good performance.  Also, some games I play now require lower graphics settings or I get under 10FPS, where I used to get 30.  I have confirmed this is a software problem by booting with a LiveCD, and everything worked the way it used to there.  Also, possibly related, the 2.6.24-19-openvz kernel could use my graphics card without a problem, but 2.6.24-21-openvz will only start in low graphics mode.  For now, I have to use 2.6.24-21-generic.

According to google, the 306US has an Intel 950 GMA graphics adapter (probably a 945GM / GME chipset)

I am not familiar with any recent changes/updates to Ubuntu Hardy that would have a negative impact on the performance of the GMA 950. However, you might check the xorg log ('less /var/log/Xorg.0.log' on the command line or Administration | System Log | Xorg.0.log in the gui) and syslog to see if there are any error messages related to "dri" "glx" "i915".

Hmm. What is the output of the command 'glxinfo'?

"direct rendering: No"

Not good. drm/dri is probably failing to load for some reason. Can you find anything else in the logs related to that?

Do 'lsmod', do you see "i915" and "drm" listed? If not, look through the logs and see if you find any error message indicating that they failed to load for some reason.

Also, this problem seems to have started when I first started playing Sauerbraten.  It caused my computer to hang and require a restart twice.  Could it be related?

Update: tried a friend's suggestion of adding this to the Device section of xorg.conf, to no avail:

Can you give the output of 'LIBGL_DEBUG=verbose glxinfo'?

I think I might finally have found what the problem is.

Do a
sudo apt-get remove xorg-driver-fglrx

Then try
LIBGL_DEBUG=verbose glxinfo

and tell me if the LibGL errors disappeared and if "direct rendering: No" changed to Yes.

That did put direct rendering back to yes and fix the LibGL errors.  How was that package causing the problem anyway?

Did it fix your performance problems?

As for the exact reason why, I'm not sure. Some people having the same problem/symptoms that you have managed to fix it by removing the fglrx package. From the discussions I could find on the problem, the cause is probably that either a kernel module (i.e. a driver) or a background deamon included in the fglrx package interferes with loading the proper _dri.so for your graphics chip.

That fixed the performance problems in all kernels except 2.6.24-21-openvz.  It still boots into Low Graphics mode there, but everything else is fine.

That's one down, one to go. ;-p

Do you see any obvious differences in lsmod, /var/log/syslog and /var/log/Xorg.0.log when running 21-openvz compared to other kernels? i915, dri/drm would probably be the things to look for but there might be other causes.

"agpgart: disagrees about version of symbol struct_module"

This usually means that the agpgart.ko you are trying to load is built/compiled for a different version of the kernel. The "Unknown symbol" errors are follow-on errors caused by agpgart not being loaded.

Now to figure out why we don't have the correct agpgart.ko for -21-openvz...

'find /lib/modules/2.6.24-21-openvz' says what?

Also for each of the files the above command lists, could you do:
dpkg -S full-path-to-file

Sorry. 'find /lib/modules/2.6.24-21-openvz -name agpgart.ko'

Tried your second one, and also did it for all 4 of the kernels:

$ find /lib/modules/2.6.24-21-openvz -name agpgart.ko
/lib/modules/2.6.24-21-openvz/kernel/drivers/char/agp/agpgart.ko
/lib/modules/2.6.24-21-openvz/ubuntu/char/intel-agp-ich9m/agpgart.ko
$ find /lib/modules/2.6.24-21-generic -name agpgart.ko
/lib/modules/2.6.24-21-generic/kernel/drivers/char/agp/agpgart.ko
/lib/modules/2.6.24-21-generic/ubuntu/char/intel-agp-ich9m/agpgart.ko
$ find /lib/modules/2.6.24-19-openvz -name agpgart.ko
/lib/modules/2.6.24-19-openvz/kernel/drivers/char/agp/agpgart.ko
/lib/modules/2.6.24-19-openvz/ubuntu/char/intel-agp-ich9m/agpgart.ko
$ find /lib/modules/2.6.24-19-generic -name agpgart.ko
/lib/modules/2.6.24-19-generic/kernel/drivers/char/agp/agpgart.ko
/lib/modules/2.6.24-19-generic/ubuntu/char/intel-agp-ich9m/agpgart.ko
$

Got this from dpkg -S commands:

$ dpkg -S /lib/modules/2.6.24-21-openvz/kernel/drivers/char/agp/agpgart.ko
 
linux-image-2.6.24-21-openvz: /lib/modules/2.6.24-21-openvz/kernel/drivers/char/agp/agpgart.ko
$ dpkg -S /lib/modules/2.6.24-21-openvz/ubuntu/char/intel-agp-ich9m/agpgart.ko
linux-ubuntu-modules-2.6.24-21-openvz: /lib/modules/2.6.24-21-openvz/ubuntu/char/intel-agp-ich9m/agpgart.ko
$

Also, doing dpkg -S for the other listed files yielded the same result, except for the different kernel in the package name.

That looks perfectly normal.

Could you try uninstalling/reinstalling the packages and see if that helps?
  sudo apt-get remove linux-image-2.6.24-21-openvz linux-ubuntu-modules-2.6.24-21-openvz
  sudo apt-get install linux-image-2.6.24-21-openvz linux-ubuntu-modules-2.6.24-21-openvz

Then reboot and see if the agpgart symbol struct_module error goes away.

If that doesn't fix it, it might be that the 21-openvz packages somehow managed to include bad versions of agpgart.ko. I looked in the ubuntu bug system, but didn't find anything specific for the GMA 950 (did however find a fglrx/agpgart problem reported in 21-openvz). I can test this on a machine here too, but it will take some time.

Just tested -21-openvz on a machine here that has GMA 950 gfx. I get the exact same problem. This pretty much proves that the Ubuntu folks managed to ship the -21-openvz kernel with a bungled agpgart driver. I'll write up a report on it in their bug tracker so that it can be fixed in -22 or -23.

In the meantime, I guess you will just have to use -21-generic or -19-openvz.
