i've installed mandrake 9.1 on a thinkpad 390 - very straightforward installation by the way. everything works great so far, except i can't change the screen resolution - i want to increase the screen area. if i go to mandrake control center - hardware - change screen resolution - i have three options, 640x480, 800x600, or 1024x768 (where it is currently set). if i choose one of the other options, it tells me i have to reboot for the changes to take, effect. but after rebooting, the screen looks exactly the same, even though the new settings appear in the control center.
I don't know if mandrake has xvidtune (i'm on FC3), but you should give it a try from console.
If it does have it, make all the necessary changes, and then press 'show'.
A line with some parameters will be shown. Copy/paste this line to your /etc/X11/xorg.conf (or xfreeconfig/xfreeconfig-4) in the section "Monitor" and put the word Modeline in front, like:
hi - i tried your suggestions of editing the x configuration manually and xvidtune, but they didn't have any effect. the screen resolution is stuck on 640x480 or so - too small to be useful for browsing, word processing, etc.
i looked around the web and found that a lot of people have problems with screen resolution, both with mandrake and other distributions. any other suggestions?
