cannot change resolution Rh9.0


Hello,

i use redhat 9.0 with gnome. when i first installed, i could change the resolution. But for fixing an optical mouse slowness problem today, i first mess with xf86config and it gave an error and resolutin changed to 800x600). after that, i fixed the mouse issue but this time i am unable to change resolutin to 1024x768 from anywhere, i tried all the applications but no luck. One problem is i use a new KDS monitor, which linux could not detect. But it was fine with it anyway. What could be the problem? My craphics card is radeon 8500LE , and it works fine .

thanks for any help.

is 1024x768 an option in your xf86config file??
and are you saying you went to the display properties in kde and selected 1024x758 and upon restarting X it didn't change?

exactly. i changed from system settings, and it makes the options in xf86config only 800x600 and 600x480 no 1024x768. even if i add the 1024x768 by myself, screen resolution does not change. i start x, changed to root, reboot, but no luck.

ok manually set it in your config file and then try it, and then when it does go back into x post anything suspicious in your /var/log/xfree86.0.log file

Many thanks, problem is solved.
i did as you said, then i saw that monitors scan frequencies are way too low. Because RH9 could not recognize monitor after i messed XF86config file. Now i tune them with the information i have found in net about the monitor, works like a charm
thanks again.

If you want to do it with the GUI sometime you can go to the Display settings / Advanced, click the Configure button. If your monitor is not listed choose the right max res under generic, and set the freq ranges.
