low res video mode

[glenn]

I have been hoping someone will solve the video config problem on FC6.

The problem does NOT occur prior to FC6. Since then, it has random 
started in 800x600x24 mode (a useless mode), or my selected mode 
(greater than 1024x768x24).  Until this last yum update, the video would 
randomly choose one of the above modes.  But with this latest update, it 
will only come up in SVGA (useless mode).

The modes beyond 800x600 are not available so I am shut down, and forced 
to use this alternate host what is limited to 1024x768.

My host has the following:

AMD 2000+ CPU
1 GB of DDR DRAM
Nvidia 5200 video
19 inch KDS monitor

Does anyone know how you can modify the grub command, or the 
/etc/X11/xorg.conf to select video res that is above 1024?

I would have written a BZ long ago, but I assume this is a common 
problem in the test community.

Your X log will tell you why the modes are being rejected.

Tnxs for the suggestion.  I have compared Xorg.0.log vs Xorg.0.log.old. 
In both cases the system has detected I have a CRT monitor.

In the good case, the monitor is detected as a "KDS visual-sensation" 
model, while in the alternate case it does not recognize the monitor and 
thus assumes it is a generic monitor.  This latter result limits the res 
offered to either VGA or SVGA ONLY.

This is NOT a problem with any distro prior to FC6.  If I swap hard 
drives to an FC5 (or FC4), the monitor is always detected correctly and 
the full set of modes are offered.

I suspect the reason you never saw this prior to FC6 was that your 
xorg.conf always had sync ranges written out for your monitor, so even 
when DDC failed it still gave you more or less the range of modes you 
expected.

I'm working on caching the DDC info though.

I have a bugzilla entry in for a similar issue where my LCD monitor wasn't
detected. I used system-config to set the appropiate monitor and then I
could select the native resolution in my user preferences.
