Currently the algorithm for video mode selection prefers the highest resolution. Would it be possible to change it to prefer the highest refresh rate? Also, I know that I can use systemsettings to change the resolution in KDE, but what do I do in a twm session? Chris
The most basic way to do this is the file /etc/X11/xorg.conf If you don't have such, create it by calling from the console X -configure ... when Xorg is _not_ running. You may do a »init 3« to deactivate a running Xorg (and activate it later again by »init 5«). Move the newly created file /root/xorg.conf to /etc/X11/
Edit the file and change the »Section Screen«, which looks like this in my case:
Section "Screen" Identifier "Screen0" Device "Card0" Monitor "Monitor0" SubSection "Display" Viewport 0 0 Depth 24 Modes "1600x1200" "1400x1050" "1280x960" "1152x864" "1024x768" "800x600" "640x480" EndSubSection EndSection
You see, the first resolution to select is 1600x1200. If I wanted 1024x768 to be the first, I just would change the order here. You can search in the file /var/log/Xorg.0.log for lines containing the word »Modeline« to see which resolutions are supported by your monitor. Usually for every supported resolution Xorg takes the highest possible frequency.
Okay, this was very short now; don't hesitate to ask again. ;-) Werner
This is all good and well, except that it takes us several years back. If I change the monitor attached to the graphics card, I have to repeat the process. I think it would be reasonable to expect the X server to pick the highest resolution for the highest frequency, not the other way round. Or at least to be configurable to do so.
