I have a Dell P1110 21" Trinitron monitor and a IBM Thinkpad X23 running Redhat 7.3. My problem is that I cannot get X to go above a resolution of 1280x1024 at 85Hz. Here is an excerpt from my XF86Config-4 file: Section "Monitor" Identifier "Monitor1" VendorName "Unknown" ModelName "Unknown" HorizSync 30.0-121.0 VertRefresh 48.0-160.0 Option "dpms" Modeline "1400x1050@75" 176.64 1400 1432 2096 2128 1050 1070 1083 1103 EndSection The Modeline wasn't working correctly. I want my monitor to be a 1400x1050 resolution. In Windows XP this computer can drive the monitor at a much higher resolution 1600x... Any ideas as to how to get the monitor to run at a higher refresh rate, as I am out of ideas. The Thinkpad is running an ATI Radeon Mobility M6.
