Public bug reported:
Binary package hint: xorg
Applies to:
Ubuntu 10.04 LTS
xorg 1:7.5+5ubuntu1
fglrx 2:8.723.1-0ubuntu3
1. Loaded 10.04 using Wubi on an Alienware M17 laptop (also called OCZ
Whitebook, based on the Arima W840D Chassis).
2. Testing showed system worked correctly out of the box with RADEON
xorg driver.
3. Switched to ATI FGLRX driver using menu item
"System/Administration/Hardware Drivers".
4. Multiple functional errors found with FGLRX.
- xorg provides no output to the Internal LCD, but external VGA and HDMI both
have output.
- xorg outputs to virtual terminal 8, no other virtual terminals display
anything on any screen.
- Catalyst control center recognizes the existence of the LCD, but thinks it is
a 1400x1050 panel (It is actually 1920x1200).
This is probably very specific to fglrx on the Alienware M17. The log
files do not show any real errors, which makes it hard to understand the
issue. Searching the Internet uncovered a small number of forum posts
from lost souls with the Alienware M17 that have been having this
problem for quite a while, but as there are no obvious faults, community
response was close to zero.
I have also verified (by doing clean Wubi installs, and updating to the
latest updates) that the issue also existed in Ubuntu 9.04 and 9.10 on
the same Alienware M17.
I do not really understand the xorg architecture well enough to know
whether this is a problem with an xorg component, or solely the ATI
fglrx driver. If I understand it correctly, xrandr is supposed to probe
for screens and resolutions and does so properly when using the default
radeon driver. The xorg log files suggests that the fglrx driver uses
its own version of xrandr, which sees the hardware, but complains a bit
about not recognizing hardware or not supporting it.
If there are any suggestion that I could try to resolve this, or
anything I can do to provide further information, not already provided
by ubuntu-bug, please let me know.

No display on LCD panel when the fglrx driver is installed. Display on external
VGA still works.
