You shouldn't have vga installed, it might be removed from the archive soon anyway. The error is from the poulsbo driver, which doesn't seem to be rebuilt against the new xserver..

[Oliver Grawert (ogra)]

this is on a ltsp client which simply installs the xorg metapackage (depending on xserver-xorg which in turn pulls in xserver-xorg-video-all).

[Timo Aaltonen (tjaalton)]

x-x-v-all doesn't depend on -vga anymore, so I'm not sure why it would be pulled in this case.

[Oliver Grawert (ogra)]

removing the vga driver helps a bit, but it chokes on the -nsc driver now (same error message), removing that one as well makes Xorg -configure work as expected again.

[Timo Aaltonen (tjaalton)]

ok, so now the -nsc driver is broken..

[Loïc Minier (lool)]

How come there aren't provides/conflicts to prevent installation of old drivers with xservers with a different ABI?

I had the same problem with an network upgrade from hardy to intrepid

I have a geforce FX5500 connected to a VGA CRT and an HDTV with a DVI to HDMI cable. Hardy xorg.conf was set up with separate x servers, configured with nvidia-settings.

On first reboot after upgrade, x-server crashed and I was set back to command prompt ( no bulletproof x ?? )

Xorg -configure also crashed with the following error message: Xorg: symbol lookup error: /usr/lib/xorg/modules/drivers//vga_drv.so

I fixed it by doing the following:
 - renamed /usr/lib/xorg/modules/drivers/vga_drv.so to /usr/lib/xorg/modules/drivers/vga_drv.so.off
- then renamed /usr/lib/xorg/modules/drivers/nsc_drv.so to /usr/lib/xorg/modules/drivers/nsc_drv.so.off after seeing the same error message as for vga_drv

Xorg -configure then wrote a working xorg.conf

Hi,
I have a ltsp client system that actually uses the NSC driver, so removing it is not an option for me. I was planning on /using/ it.....

[rew (r-e-wolff)]

On or around (I've been debugging the code a bit) line 520 of src/nsc_driver.c is the call to xf86GetPciVideoInfo .

It is intended to detect wether or not PCI is available at all. I changed this to if (1).

If PCI is NOT available, the xf86MatchPciInstances calls in the following lines will silently return "no devices found". I actually tested that because I cut out too much of my machine's bootsequence, so that PCI wasn't available anymore.

   /* PCI BUS */
   if (xf86GetPciVideoInfo ()) {
      numUsed = xf86MatchPciInstances(NSC_NAME, PCI_VENDOR_ID_NS,

becomes:

  /* PCI BUS */
   if (1) {
      numUsed = xf86MatchPciInstances(NSC_NAME, PCI_VENDOR_ID_NS,

More info needed? Mail me... :-)

Hi ogra,

Please attach the output of `lspci -vvnn` too.

Ogra is the original reporter for this bug report.

The automated script processes bugs in state New. It looks for certain information, such as lspci or Xorg.0.log, that is needed 95% of the time. Some bugs like this fall into that last 5%, but it is often very hard to programmatically detect these cases.

[rew (r-e-wolff)]

Apparently the suggestion to drop nsc was followed for jaunty. I can't say I'm thrilled: My openbricks need the module to display anything....

[Bryce Harrington (bryce)]

Support for -nsc has been merged into xserver-xorg-video-geode, and so we no longer support the -nsc driver on Karmic.

Please test this bug with -geode, and if it still occurs you should re-file it against the geode package via the following command:

  ubuntu-bug xserver-xorg-video-geode
