Description T. Scott Talbot 2004-08-24 20:06:39 UTC
After install of xorg-x11-6.7.99.902-4, X is having even more problems.  When I
change screen modes, I get a portion of the entire raster showing in the upper
left of my monitor.

The change is now, with kernels > kernel-2.6.8-1.524 and rhgb running, vga
screens show up the same way, i.e. changing to a console yields a "screen"
approximately 1/3 of full height of monitor, which shows 5 "columns" analogous
to the single left hand input of the console screen.

only fixes are to use kernel <= .524 (no good as there's no CD-Rom support,
remove rhgb from kernel args (no problem, but Red Hat might not like that!

in case you need it I use ATI Radeon 7200 gfx card
Comment 2 Jim Cornette 2004-09-15 14:45:57 UTC
I filed a bug against the radeon driver - bug 1384 - I tried the server version
with an i810 driver and it experienced a refresh problem without DRI active.
This might give some insight into where the driver and server departed ways.

Also, while using the vesa driver, I get the below for mtrr (32 MB). This seems
correct.

 cat /proc/mtrr
reg00: base=0x00000000 (   0MB), size= 512MB: write-back, count=1
reg01: base=0x1ff00000 ( 511MB), size=   1MB: uncachable, count=1
reg02: base=0xe8000000 (3712MB), size=  32MB: write-combining, count=1
