Betreff: Blank screen on Radeon Mobility HD 4650

Hi,

I am experiencing a problem with my new laptop :
Dell Studio 17'3 with Radeon Mobility HD 4650
running opensuse 11.2 or Ubuntu 9.10

When xorg invoked, the screen becomes blank and is deadlocked this way
until the next reboot, and then KDE4 crashes.
It occurs both with "radeon" and "radeonhd" drivers.

For information :
http://88.191.15.45/RVRV/xorg.conf
http://88.191.15.45/RVRV/Xorg.0.log
http://88.191.15.45/RVRV/xsession-errors

Actually it seems to be a combination of two distinct problems, may be
related :

1/ Once Xorg invoked, the laptop panel is deadlocked blank, but with no
apparent errors in xorg.conf. Except for a VGA output initialization,
despite no monitor ever being attached to the VGA output.
Maybe the flat panel isn't correctly probed / detected ?
What surprises me is : if I plug the HDMI output to another monitor, I can
see KDE4 loading before it crashes (see below).

2/ KDE4 appears to crash due to some errors, see xsession-errors :
kdeinit4: preparing to launch /usr/lib64/libkdeinit4_kglobalaccel.so
WARNING: Application calling GLX 1.3 function "glXCreatePixmap" when GLX
1.3 is not supported!  This is an application bug!
WARNING: Application calling GLX 1.3 function "glXQueryDrawable" when GLX
1.3 is not supported!  This is an application bug!
drmRadeonCmdBuffer: -22. Kernel failed to parse or rejected command
stream. See dmesg for more info.
kded4: Fatal IO error: client killed


When running "vesa" or the proprietary "fglrx", it is working quite
alright, except for the horrible 2D performance.

Any advise welcome,

Damien
