Monitor: Samsung SyncMaster 172x (LCD) XFree86 4.3.0.dfsg.1-1 (Debian Sarge) nVidia nForce 220D xfree driver: nvidia
Initial problems: 1. Desktop too large for screen. 2. Unable to get 1280x1024 mode (max 1024x960)
Initial XF86Config-4 settings (from monitor manual): Horizontal sync.: 30-81 Vertical sync.: 56-75
Solution (after much tinkering):
1. Reduce horizontal sync. range to 30-79.
2. At one point I had to use a default screen depth of 16 to enable X to get 1280x1024, but at the last it seems be working even with 24.
Here are some snippets from my XF86Config-4 file:
