Description Martin Mokrejš 2010-01-03 12:05:40 UTC
During startup of xdm the "Xserver" turns off&on my LCD display few times but in the end the screen is black although with some backlight enabled instead of the big X mouse pointer being show by X and later the xdm-login window should have appeared.

in var/log/xdm.log I see:
do_ioctls: Failed to get GB pipe count, error number -22
xdm error (pid 8913): server unexpectedly died
xdm error (pid 8913): Server for display :0 can't be started, session disabled

I looks it could be an old bug or something new?

My hardware is ASUS L3C/S laptop with and old radeon 7500M PCI card.

BTW, have no /etc/X11/xorg.conf, I rely completely on autodetection as the upgrade from 1.6 series xorg-server to 1.7 somehow did not work with my xorg.conf.

Comment 3 Martin Mokrejš 2010-01-03 14:59:28 UTC
This has to do with my upgrade away from x11-base/xorg-server-1.7.3 to x11-base/xorg-server- (I cannot revert as the original ebuild is now gone from portage), or x11-libs/libdrm-2.4.15 to x11-libs/libdrm-2.4.17 transition or lest likely with app-laptop/radeontool-1.5-r3 to app-laptop/radeontool-1.6. upgrade.

Recompilation of x11-drivers/ libdrm, xorg-server, mesa does not help. I will re-try downgrade of libdrm although I did that without any luck.

BTW, I have x11-drivers/xf86-video-ati-6.12.4 for about two months so that cannot e the cause.

So, I tried downgrade of libdrm, xorg-server to 1.7.3-901-r1, recompiled x11-drivers/, mesa-7.7-r1, no luck.

I finally have a functional system (getting xdm login) after downgrade to media-libs/mesa-7.5.2. I will attach xdm.log and files for this working situation.

Comment 7 Martin Mokrejš 2010-01-03 17:19:19 UTC
And, decent upgrade of mesa to media-libs/mesa-7.6.1 did not break my system so I conclude the bug got introduced between 7.6.1 and 7.7.
Comment 8 Corbin Simpson 2010-01-03 19:52:31 UTC
You are using Radeon Gallium without KMS enabled. This will never work.

Not sure how to properly close this. Please file Radeon Gallium bugs upstream and keep in mind that it is testing-quality and not meant for production use.

Also, if the ebuild is enabling Radeon Gallium by default (without USE="gallium") then I would consider that a bug on the ebuild.
Comment 9 Martin Mokrejš 2010-01-03 22:26:16 UTC
If you mean the nomodeset kernel options I can drop then. I was just hoping they they would help. See ArchLinux nice wikipages. They disabled KMS for the whole distro recently until it stabilizes.

Yes, I believe this is an ebuild issue as I do not alter any USE flag for the KMS/gallium stuff. It must come from my profile.

# emerge -pv mesa

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild     U ] media-libs/mesa-7.7-r1 [7.6.1] USE="gallium* motif -debug -nptl -pic (-selinux) -xcb" VIDEO_CARDS="radeon -intel -mach64 -mga -none -nouveau% -r128 -radeonhd -savage -sis (-sunffb) -svga% -tdfx -via (-s3virge%) (-trident%)" 0 kB


Nevertheless, would you please comment on the "do_ioctls: Failed to get GB pipe count, error number -22" problem? In which version of what package should be the fix. Any clues when was that problem introduced, if it did not exist since e.g. KMS support started to accumulate in that package. Is that really in mesa? 

So "USE=-gallium emerge mesa" should work for me? Does it have to do with the modeset kernel options at all? Thanks.
Comment 10 Corbin Simpson 2010-01-03 23:21:34 UTC
The error is in Mesa, in src/gallium/winsys/drm/radeon/core/radeon_drm.c, and it means that either your video card isn't a Radeon, or that you don't have KMS enabled.

This is not a bug. I explicitly did not write DRI1/UMS/legacy support into the Radeon Gallium code. You must be using KMS and a DRI2-capable Xserver.

To resolve the error, go kick the ebuild and/or profile maintainers, and notify them that there is no good reason to enable Gallium yet, since no Gallium drivers are production-quality at this time.

Also, the version of the Radeon Gallium drivers in Mesa 7.7 is not very stable; even if the USE flag remains on, I would highly encourage removing --enable-gallium-radeon from the configure line for that version of the ebuild.
Comment 11 Martin Mokrejš 2010-01-04 09:12:26 UTC
Thanks for clarifications. I do see some DRI2 messages in the Xorg.log and do not think I asked for that. The chip is from 2001 or so, probably DRI1 only. Maintainers are now CCed so they should have received already their copies. Thanks once again.
