RHEL4 and Dell D600 Latitude graphical nightmares persist

SteveInTallyFL · 05-04-2009, 11:33 AM

Has anyone EVER successfully gotten X under RHEL 4 on the Dell D600 to work in anything other than pure native resolution (1400x1050)? Every time I try to adjust to a lower resolution (oh, the eyes of the aged grow dim. . .) it kills the X environment completely.

This is the 2003-era model with the ATI Radeon M9 onboard adapter and the generic TFT laptop display (SH1398).

Any magic bullets for the xorg.conf or otherwise will be appreciated.

I haven't used exactly your hardware setup, but I have had issues with ATI cards and resolution issues. I also got results installing the proprietary ATI drivers under Fedora. Have you ever tried that? http://support.amd.com/us/gpudownload/Pages/index.aspx

Is it possible that the issue is less with the ATI driver than it is with the modeprobe for the screen? In the xorg.conf for this radeon driver there is a long list of modeline statements with a variety of settings. It is as if these settings are incompatible with the frequency ranges assigned to the display itself.

Hos would I discover the appropriate freq ranges for this screnn? Dell provides no assistance in their documentation.

Many thanks, zQUEz. This installation has performed flawlessly. I now have 1024x768 resolution and can read everything on screen comfortably.
