Description g.puneet 2009-10-08 12:23:40 UTC 
Description of problem:

There are few issues I observed with r500. 

1. If user switches to 640x480 using xrandr and wants to come back or to some other resolution. It is not possible. System will always throw a black screen. 

2. If user switches to 1440x900 resolution using gnome-display-properties. system will safely come to said resolution but display will keep blinking. 

Version-Release number of selected component (if applicable): 5.3

Comment 4 David Batson 2009-11-29 05:31:39 UTC 
I believe I ran into the same problem.  I tried to change the default resolution on my T42 ThinkPad with the ATI mobility Radeon 9600 SXGA+ display using System > Preferences > Display.  Everytime I changed the resolution to from the native SXGA+ to XGA, I would get a black sceen.

I discovered adding nomodeset to the kernel line in /boot/grub/menu.lst resolved this problem for me.

<code>
default=0
timeout=5
splashimage=(hd0,4)/grub/splash.xpm.gz
hiddenmenu
