Description Phil Long 2008-04-18 18:08:37 EDT
Description of problem:

The hardware is the ATI Radeon 3200 in the 780G chipset driving a Westinghouse
24" 1920x1200 monitor.  All of which is properly detected by X via PCI discovery
and EDID.

However, X chooses to drive the monitor at 1600x1200 resulting in distortion and
2D performance that is lacking.  Well, lacking does not even come close; 2D
reminds me of the days when people loved the imagine #9 because it could do 2D.

Further, Fedora top menu bar->System->Preferences->Hardware->Screen Resolution
includes things like 1600x1200 and 1440x1050 but not the EDID detected 1920x1200.

3D is also lacking (240 fps glx gears compared to 2k fps glxgears using ati's
driver), but that's unsurprising. 

Version-Release number of selected component (if applicable):

How reproducible:

Install Fedora 9 Preview

Steps to Reproduce:
1. Assemble a 780G system
2. Install Fedora 9
Actual results:

Expected results:

.... *sigh*

Additional info:

EDID line from /var/log/Xorg.0.log:

(II) VESA(0): Modeline "1920x1200"x0.0  154.00  1920 1968 2000 2080  1200 1203
1209 1235 +hsync -vsync (74.
0 kHz)

Workaround is obviously to go find ATI's unfree catalyst drivers or, figure out
how to help Novell finish the radeonhd driver ..

can you attach the xorg log?

There is no acceleraton for this hardware available, granted it shouldn't be
unuseably slow but it is all being rendered by the CPU so it won't be that fast.
Comment 2 Phil Long 2008-04-28 07:31:24 EDT
I blanked F9 preview in favor of Mythdora 5 beta2 and am testing that at the
moment so I don 't have more of the log than I posted.  I *smacks forhead* I
shouldda done that.
