Description Tom Kincaid 2006-11-20 19:52:44 UTC
Description of problem:

I have a T41 system, a docking station and an external DELL Monitor. When I boot
in this configuration, the external monitor does not get the naitve screen
resolution and things large and fuzzy. 

Also: System -> Preferences -> Screen resolution only had a few low resolution
choices. Far fewer than the resolution choices that I had in RHEL 4.4.

I had Ajax come over and take a look. His explaination, which I am not going to
do justice to was that we optimized for the external device being a projector
for RHEL 5. 

He had me put the following in my /etc/X11/xorg.conf file to work around the
problem.

Section "Device"
        Identifier  "Videocard0"
        Driver      "radeon"
        Option "MonitorLayout" "NONE,CRT" # This being the key line.

Unfortunately, this means that in order for me to boot my laptop with out an
external monitor, I need to comment out the following line:

 Option "MonitorLayout" "NONE,CRT" # This being the key line.

I am not sure what the right solution is here but I don't think the current
situation is acceptale for GA. One thought I had was to have a menu pick along
the lines of:

Choice 1: Optimize desktop for external desktop monitor
Choice 2: Optimize desktop for external projector monitor.

As this is critical for laptop use - especially at Red Hat. PM ACK

The bug as written isn't workable.  I've discussed the multihead strategies and
support status with rousseau and jneedle.  As they find issues they will open
individual bugs for them.

In particular, the semantics you really want here are which monitor among many
to give preferential treatment to, which is not the same thing as
monitor/projector, so exposing that as the UI is completely the wrong thing to do.

Marking as NOTABUG, for lack of INVALID status.
