Last time I had trouble with monitor resolutions, I dealt with it using `xrandr'
[rocketmouse@archlinux ~]$ grep modeli /etc/X11/xorg.conf modeline "1152x864" 128.42 1152 1232 1360 1568 864 865 868 910 [rocketmouse@archlinux ~]$ cvt 1152 864 90 # 1152x864 89.80 Hz (CVT) hsync: 81.99 kHz; pclk: 127.25 MHz Modeline "1152x864_90.00" 127.25 1152 1232 1352 1552 864 867 871 913 -hsync +vsync And how can the depth be set? http://www.x.org/archive/X11R7.5/doc/man/man1/xrandr.1.html I didn't read it, I just searched by Ctrl+F.
