I just got a Samsung SyncMaster T260HD monitor. It works straight out of the box with Windows but I can't seem to get it to work with Linux, which is my primary OS for day to day work.
The computer boots up but when going into graphical mode on Linux the monitor gives me a "Mode not supported" error and doesn't display anything.
I booted up windows and, using PowerStrip, grabbed the exact ModeLine that should be used to get the equivalent setting in Linux and added it to my xorg config file but it doesn't seem to help. the ModeLine is:
ModeLine "1920x1200" 153.9 1920 1984 2016 2080 1200 1203 1209 1235 +hsync -vsync
This is the modeline for the working display settings in windows but it doesn't seem to work in Linux My complete entry in the xorg.conf file for the monitor is
Section "Monitor" Identifier "Monitor0" ModelName "SyncMaster" DisplaySize 518 324 HorizSync 30.0 - 81.0 VertRefresh 56.0 - 75.0 Option "dpms" ModeLine "1920x1200" 153.9 1920 1984 2016 2080 1200 1203 1209 1235 +hsync -vsync EndSection
I'm running Scientific Linux 5.4 (clone of Redhat Enterprise Linux 5.4) but I've tried booting with a recent Linux Mint Distro as well as Ubuntu 9.04 and had the same problem. Any suggestions on other things I should try or might be missing? If anyone's gotten this to work I'd love to know. Thanks.
