I have done a new installation of opensuse11.3 on a HP Proliant 350ML G5.
The video card is an ATI ES1000 515E

In Opensuse 11.2 I used a dedicated xorg.conf for the video and the radeon driver; The Screen is a Benq monitor with a maximum resolution of 1900*1200
In opensuse 11.2 I only could define the screen with a resolution up to 1600*1000.

Now in Opensuse 11.3 the installation finished with a configuration using fbdev with a maximum resolution of 1024*768. I followed the guide openSUSE Graphic Card Practical Theory Guide for Users
and created a xorg.conf with command
Code:
 Xorg -configure
This didn't give a correct xorg.conf : still using fbdev .
I tried the next things
1) I overwrote the new xorg.conf by the xorg.conf from Opensuse 11.2 but this ended in a black screen and I needed to kill the X server.
2) with point & still present I added the command nomodeset by starting Linux: the X server started but KDE colors where very dark and mostly all were dark green but the resolution was at 1600*1000
3) I removed the xorg.conf and inspected the /etc/X11/xorg.conf.d/50-*.conf files. Therein I found the driver radeon but as comment (prefixed by #). I activated the radeon driver and could start KDE but the maximal resolution was 1280*1024
4) I added then the different modeline from my opensuse11.2 xorg.conf in file 50-monitor.conf
and I can see some of it in Configure Desktop ( up to 1440*900) but the 1600*900 and 1600*1000 are not shown

They are defined in 50-monitor.conf
Code:
Section "Monitor"
  Identifier "Default Monitor"

In the Xorg.0.log I found this remark
Code:
(II) RADEON(0): Not using mode "1600x1000" (mode requires too much memory bandwidth)
Can I add some info in the 50-*.conf files about the monitor?
Any idea how going to resolution 1600*1000 or 1600*900?
Why was this working with Opensuse11.2?

Many thanks in advance
