Hi Dan Can you attach (plain/text) the dmesg output of 3.3.0 and 3.2.12 Cheers Emil Created attachment 58989 [details]
dmesg from 3.3.0
Created attachment 58990 [details]
dmesg from 3.2.12
dmesgs attached as requested... having just compared them myself, I think the interesting bit is around line 396 in 3.3.0... but I'm not the expert :) Cheers Dan A quick look indicates * VGA switcheroo: detected Optimus DSM method \ handle The above should not be relevant to your issue * 0xE4DC: Parsing digital output script table Most likely causing the problem Would you mind attaching your vbios [1] and providing more information regarding your display/setup eg. * Primary - connected via the VGA (card), DVI to VGA converter used - xxx monitor * Secondary ... Have you tried booting with the secondary monitor only (unplug the primary) ? Cheers Emil [1] cat /sys/kernel/debug/dri/0/vbios.rom > vbios.rom Note: assuming that you have debugfs mounted on "/sys/kernel/debug" Uh oh, that DSM message possibly comes from a bug fixed by the patch at http://lists.freedesktop.org/archives/nouveau/2012-March/010056.html Since the value is uninitialized, there is a chance that is_optimus == 1. This should not be a problem here though since it only signals the switcheroo module that switching is possible. Running on NV34 [GeForce FX 5200] (rev a1) and upgrading from 3.2.10 to 3.3 (both mainline, ie not gentoo-sources) I experience the same symptoms, but in this case it is the primary (and only) VGA monitor that turns black when drm initializes during boot. Just as in Dan Goodliffe's bug report in Gentoo's bug tracker everything seems to work normally except that the console stays black, my monitor reports a valid graphics mode, and DPMS turns off the monitor after the expected idle interval. In contrast to Dan Goodliffe I have had better luck during bisecting and end up with dea7e0ac45fd28f90bbc38ff226d36a9f788efbf as the culprit: dea7e0ac45fd28f90bbc38ff226d36a9f788efbf is the first bad commit commit dea7e0ac45fd28f90bbc38ff226d36a9f788efbf Author: Jerome Glisse <jglisse@redhat.com> Date: Tue Jan 3 17:37:37 2012 -0500 ttm: fix agp since ttm tt rework ttm tt rework modified the way we allocate and populate the ttm_tt structure, the AGP side was missing some bit to properly work. Fix those and fix radeon and nouveau AGP support. Tested on radeon only so far. Signed-off-by: Jerome Glisse <jglisse@redhat.com> Reviewed-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Signed-off-by: Dave Airlie <airlied@redhat.com> Regards, Frej Primary display is an Acer X221W connected to the DVI port with a VGA adapter. Secondary display is an Aver AL702 connected to the VGA directly. vbios coming soon... just need to boot into a kernel with support for it. Created attachment 59043 [details]
vbios.rom
Does this issue persist with newer kernels/DDX's (e.g. kernel 3.10, ddx 1.0.9)? I'm afraid I'm no longer in a position to test this, the motherboard died and the graphics card is no longer in use. Sorry. And the user who did the bisect didn't add himself to the CC list. Oh well. I'll mark it invalid then, as no one is availabe to test. It can be reopened should there be renewed interest. |
