Description Markus Heinz 2010-01-10 05:26:37 UTC

PC: Lenovo ThinkCentre with Intel onboard graphics and DVI connector card
Chipset:
00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express
Integrated Graphics Controller (rev 10)
00:02.1 Display controller: Intel Corporation 82G33/G31 Express Integrated
Graphics Controller (rev 10)
Monitor: Asus VW222U flat panel connected with a DVI cable
System architecture: 32-bit
xf86-video-intel: 2.10.0
xserver: X.Org X Server 1.7.4
mesa: 7.6.1
libdrm:2.4.17
kernel: 2.6.32.3
Linux distribution: Crux 2.6

I have upgraded the Intel xorg driver to version 2.10.0. This driver requires KMS. I have used UMS before because KMS has not worked for me so far. UMS hat its problems too (see https://bugs.freedesktop.org/show_bug.cgi?id=24282)

When booting my system with a KMS enabled kernel 2.6.32.3 the screen becomes dark and the monitor is switched into standby ("no signal"). I neither get a text console nor a xdm login.

After applying this patch https://bugs.freedesktop.org/attachment.cgi?id=30610 to the 2.6.32.3 kernel the text console and xdm login become available in the native resolution of the monitor (1680x1050).

Created attachment 32557 [details]
dmesg output with 2.6.32.3 vanilla kernel

This output has been generated with an unmodified kernel 2.6.32.3.

Comment 2 Gordon Jin 2010-01-10 05:42:10 UTC

So the patch https://bugs.freedesktop.org/attachment.cgi?id=30610 fixes your problem.

Yakui, is that patch committed?

Comment 3 Markus Heinz 2010-01-10 05:47:21 UTC

Created attachment 32558 [details]
dmesg output with 2.6.32.3 patched kernel

This output has been generated with a modified kernel 2.6.32.3 including the patch mentioned in the description.

Comment 4 Markus Heinz 2010-01-10 05:58:09 UTC

Yesterday I have tried a recent kernel from the Intel drm-next tree (2.6.33-rc3) and it failed the same way as described with the linux 2.6.32.3 vanilla kernel.

Comment 5 ykzhao 2010-01-10 17:05:18 UTC

Hi, Markus
    The patch in comment #2 is only a workaround patch and it is not shipped. Now we have a correct patch to fix this issue.
    Will you please try the following two patches in:
    >http://lists.freedesktop.org/archives/intel-gfx/2010-January/005362.html
    >http://lists.freedesktop.org/archives/intel-gfx/2010-January/005363.html

Thanks.
