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
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
