Comment 184 for bug 132716

I have an Asus a8v, athlon with an "ATI Technologies Inc M10 NQ [Radeon Mobility 9600]" and I'm experiencing the "black screen" on startup of the X server. I've done the "dpkg-reconfigure -phigh xserver.xorg", tried the xserver-xorg-video-ati_6.7.195+git20071020tv_i386.deb, and 'Option "LVDSBiosNativeMode" "false"', and I'm still getting the black screen. Here is a more detailed description:

Start with running system using vesa driver.

dpkg-query -W 'xserver*ati*'
xserver-xorg-driver-ati
xserver-xorg-video-ati 1:6.7.195+git20071020tv
xserver-xorg-video-ati-dbg
xserver-xorg-video-atimisc
dpkg-reconfigure -phigh xserver-xorg
Ctrl-Alt-Backspace

Result:
  Monitor goes into power save.
  Xorg starts consuming CPU, is not able to be killed (even with -9).

Reboot.
  Results unchanged.

ed xorg.conf s/"ati"/"vesa"
reboot.

  Works fine.

ed xorg.conf s/"vesa"/"ati"

apt-get install xserver-xorg-video-ati
dpkg-query -W 'xserver*ati*'
xserver-xorg-driver-ati
xserver-xorg-video-ati 1:6.7.195-1ubuntu2
xserver-xorg-video-ati-dbg
xserver-xorg-video-atimisc

Ctrl-Alt-Backspace
Result:
  black screen, xorg max cpu, unkillable.

Add Option "LVDSBiosNativeMode" "false"
reboot
Result:
  black screen, xorg max cpu, unkillable.
