Video card not detected (loads vesa)

[Piotr Morgwai Kotarbiński]

Binary package hint: xserver-xorg-video-intel

After manual upgrade to xserver-xorg-video-intel 2.7.99.1+git20090602.ec2fde7c-0ubuntu1 and libdrm 2.4.11-0ubuntu1 enabling UXA in xorg.conf doesn't have any effect (see Xorg.0.log file) and I can't enable compiz anymore.

Thank you for submitting your bug report!

No, actually in 2.7.99.1, no other accel mode except UXA is available (EXA and XAA are stripped out) so by definition if -intel loads you're using UXA. The setting no longer needs to be specified in xorg.conf.

Rather, your problem is that for whatever reason the xserver is not detecting your card as supported by -intel:

 (II) Scanning /usr/share/xserver-xorg/pci directory for additional PCI ID's supported by the drivers
 (II) No matches found for this device in /usr/share/xserver-xorg/pci

You may be able to work around the bug by specifying your driver as "intel" in your xorg.conf.

Piotr, could you attach the file /usr/share/xserver-xorg/pci/intel.ids ?

(I'm wondering why X wasn't able to find your pci id in that file, since it is definitely there for me.)

[Piotr Morgwai Kotarbiński (morgwai)]

That's probably the reason: after upgrade I don't have this file any more. It was included in 2.6.3-0ubuntu9.2 but 2:2.7.99.1+git20090602.ec2fde7c-0ubuntu1 doesn't have it as patch 01_gen_pci_ids.diff was removed from the sources. Is it a bug that it was removed or were pci ids files moved to another package that I have to install?

Many thanks

ah. 01_gen_pci_ids.diff was a debian-specific way to identify what driver to load based on pci id's. That functionality has been taken upstream and is now done in the xserver itself. We'll have to check out why it's not detecting your card now.

[Piotr Morgwai Kotarbiński (morgwai)]

I see. Please let me know if you need more assistance from my side (like testing with some specific options, installing packages with more debugging info, etc).

Cheers

I tried the new driver also on another notebook with an older intel graphic chip and the results are exactly the same. I'm attaching logs and output of `lspci -vvnn' from this machine.

It seems that this auto detection in the driver doesn't work reliably, so maybe it would be good idea to consider adding patch 01_gen_pci_ids.diff back until this issue is resolved?

Cheers

This bug 379504 resurfacing because you are mixing karmic and jaunty packages. In Jaunty there is a patch (01_gen_pci_ids.diff) that generates intel.ids in /usr/share/xserver-xorg/pci and a corresponding patch in xorg-server (143_default_to_vesa.patch) that has the effect of only looking for these files to determine which driver to use.

In Karmic, as Bryce said 01_gen_pci_ids.diff is removed in xserver-xorg-video-intel, and because of this, 143_default_to_vesa.patch is disabled in xorg-server.

Thanks for trying the newer driver and helping to identify problems. In this case, however, since it is the test case itself that is broken, I'm closing this bug.

[Piotr Morgwai Kotarbiński (morgwai)]

Sure, many thanks for clarification! I'm glad it's my ignorance and not another bug ;)

Cheers
