Thanks for your report. It seems like modesetting is enabled by default on this kernel? Please see https://wiki.ubuntu.com/X/RadeonKMS and see if you can boot with radeon.modeset=0, then reenable it after boot as explained there. Or if loading fbcon early enough makes it work.

[abujafar (abujafar)]

I forgot to say that i was already forcing the kernel to use KMS (this is indeed what i was testing), so it is not enabled by default.
I ran several test and the ONLY way to get DRI2 working is from console:
1 boot with KMS off
2 close X
3 reload radeon module with KMS on
4 and restart X

Putting fbcon in /etc/modules won't help.

[abujafar (abujafar)]

And by the way I am stressing DRI2 because it is the only way for me to watch Flash Video smoothly with compiz enabled.

[Tormod Volden (tormodvolden)]

I did not see radeon.modeset=1 in the kernel command line, neither in dmesg nor Xorg.0.log, that's why I thought it was default.

Did you try putting fbcon into the initrd? I was pretty sure /etc/modules is loaded before the autoloading of radeon, but with the new boot order this might be different.

I have the same problem with a Radeon Mobility 9000 (RV250). When booting on ubuntu kernel ppa 2.6.32-rc7+ or 2.6.31-drm-next with modesetting enabled via "options radeon modeset=1", dri can't be enabled, and X is switching back to Software Rasterizer. I have tried the stock drivers/mesa, the ubuntu-x, and the xorg-edgers ppa. All these packages work fine on 2.6.31-14. After some research, I ended up trying the ideas tormod suggested on #radeon (fbcon loaded earlier) : http://www.radeonhd.org/?page=archive_display&c=radeon&m=10&y=2009&d=2009-10-28, but none of them fixed the problem.

I need recent KMS because of #444139 and other freezes/crashes when using DRI1, and #413259 which was fixed in 2.6.32 as far as I can see. Anything I can post/try ?

[bjaglin (bjaglin)]

After reading https://wiki.ubuntu.com/X/RadeonKMS, I tried to remove the splash boot option, without any success. However, starting without KMS and reloading radeon does work for me as well. So I guess I am just experiencing a known loading order issue?

[abujafar (abujafar)]

i have some good news to share. I get a working configuration using kernel 2.6.32rc8, drivers from https://launchpad.net/~xorg-edgers/+archive/drivers-only and modified gdm.conf file from https://wiki.ubuntu.com/X/RadeonKMS
Everything else to karmic's default (even the splash option at boot time).

OT question: Is it possible to specify somewhere the boot video resolution? it starts with 1280x1024@60 and then modified after login by gnome to 1280x1024@75.

[Tormod Volden (tormodvolden)]

It all works very well with lucid + xorg-edgers + the above gdm.conf on M26 (X700 Mobility). Finally suspend and hibernation works, there was one issue but it got solved as soon as I reported it on https://bugs.freedesktop.org/show_bug.cgi?id=25336

I don't think there is any way to select mode yet. When there is, I will expect it to show up in "modinfo drm" or "modinfo radeon".

[bjaglin (bjaglin)]

Using 2.6.32-6 taken from the Lucid repository on Karmic, with Ubuntu X SWAT packages, the workaround described there https://wiki.ubuntu.com/X/RadeonKMS in gdm.conf is not required anymore, KMs loads fine.

[abujafar (abujafar)]

As far as i can see, packages of X-swat are older than karmic ones. Am I wrong?

[Tormod Volden (tormodvolden)]

Use xorg-edgers, not X-swat. Yes, I don't need the gdm.conf hack either. BTW, there is also http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-next/ which has KMS bits newer than in 2.6.32 final.
