Hi list,
on SuSE10.1 AND the new SuSE10.2 (rc1) I've noticed that on my IBM ThinkPad R50 with an ATI Radeon RV250 Lf display (1400 x 1050), the installation sets the refresh rate to 75Hz.
This causes the driver circuit in my machine to go mad in about 30 minutes from power on. The screen will gradually degrade with horizontal flashing lines and eventually become completely useless.
If I (YaST) set down the refresh rate to 60Hz the screen will stay on just fine. But when moving windows around, it doesn't really look good, all vertical lines are distorted with small pieces of "horizontal noice" to them.
On SUSE10 this never happened.
Any ideas?

First, make sure that you really have an RV250 Lf. Just because some Suse app says it is, doesn't mean that it is. Suse reports that I have this ATI card, but my card is quite different.

You can set VertRefresh in /etc/X11/xorg.conf

Have you changed the "HorizSync" in xorg.conf? If not, it m will cause a problem.

Hi list
- thank you for the answer. I actually don't know if I really have such an ATI card in my IBM Thinkpad R50....Don't know really how to find out...
- I just did another thing....in YaST(sax), I selected the one and only IBM LCD display adaptor that there is to choose. This proved to be very good. Actually excellent. No distortions, all is just perfect.
- so conclusion: SuSE10.2 somehow suggested a slightly wrong driver and thus wrote a "not so good" config file for it. Once corrected, SuSE10.2 is displaywise on an R50 - just excellent.

To all in this thread...thanks again.
This is my ThinkPad card: VGA compatible controller: ATI Technologies Inc Radeon R250 [Mobility FireGL 9000] (rev 02). Everythings works like a breeze.
And the ThinkWiki is bookmarked, it's a gem!
