Your display driver might not support that resolution. Look in your X log file to see if X is able to use all the resolutions defined in your X config. ----- Original message ----- From: "Randy Clarksean" <rclark at lakesplus.com> To: "tclug" <tclug-list at mn-linux.org> Date: Thu, 02 Nov 2006 15:15:53 -0600 Subject: [tclug-list] LCD Monitor - 1440x900? I finally hooked up the Acer monitor AL2016W. I can get it to work, but only at certain resolutions. I have attached my xorg.conf file below. I made changes to it ... and the 1680x1050 works fine. The 1280x800 works fine as well ... but it is a bit course. I was hoping to get 1440x900 to work When I go into system-config-display ... i do not get any other options with the 16:10 ratio that this wide screen LCD has. In the Modes Section, the only line that is truly right (stolen off the internet someplace) is the 1680x1050 at 60 Hz ... all the others are just guesses pretty much Assistance would be greatly appreciated as the 1680 setting is too tall vertically and I can not adjust the monitor to get the lower edge to fit on the screen.
