Since upgrade 9.10->10.04 dual screen does not work anymore

[telmich]

Binary package hint: xorg

When xorg is started and both VGA-0 and LVDS are connected, the screen is pink / screwed up. Removing VGA-0 and restarting xorg or disabling the second output via xrandr makes LVDS work. Switching to VGA-0 only also screws up the screen.

This used to work with ubuntu 9.10 and stopped to work precisely after the update.

Works fine when reloading radeon with radeon.agpmode=-1:

/etc/init.d/gdm stop
echo 0 > /sys/class/vtconsole/vtcon1/bind
rmmod radeon
modprobe radeon agpmode=-1
/etc/init.d/gdm start

Update: Two screens work, also next to each other, but mplayer still chooses x11 instead of xv, which should be usable.

Upstream bugzilla entry: https://bugs.freedesktop.org/show_bug.cgi?id=28393

Not sure, which is the better place for documentation now...

[telmich (nico-launpad-net)]

with agpmode=1: Same as radeon.agpmode=-1.
with agpmode=2: Same as radeon.agpmode=-1.

with agpmode=4: Computer freezes...

[telmich (nico-launpad-net)]

Btw, each time i reload radeon, the index of VGA and LVDS increase: VGA-0 -> VGA-1 -> VGA-2.
Not sure whether this is thought to be.

[telmich (nico-launpad-net)]

Found another way to "fix" it:

kobold# echo 0 > /sys/class/vtconsole/vtcon1/bind
kobold# rmmod radeon
kobold# modprobe radeon modeset=0
kobold# /etc/init.d/gdm start

[telmich (nico-launpad-net)]

Btw, loading radeon without KMS also makes xv work with mplayer.

telmich, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xserver-xorg-video-ati REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.
