I have just had similar issue two days ago with dual setup of 1920x1200 displays on Radeon driver. For some silly reason login X chooses to default to 1280x720 (!). This is on Fedora 11. I have yet to file a bug. Here's how I sorted it out: Use cvt command to get modeline data, e.g.: $ cvt 1920 1200 60 # 1920x1200 59.88 Hz (CVT 2.30MA) hsync: 74.56 kHz; pclk: 193.25 MHz Modeline "1920x1200_60.00" 193.25 1920 2056 2256 2592 1200 1203 1209 1245 -hsync +vsync Now edit your ~/.bash_profile and add: xrandr --newmode 1920x1200 193.25 1920 2056 2256 2592 1200 1203 1209 1245 -hsync +vsync xrandr --addmode DVI-0 1920x1200 xrandr --output DVI-0 --mode 1920x1200 Note: if the xrandr --new mode complains something about X resources, change the name of the mode to something like 1920x1200_1. Note 2: In your case, s/1920x1200/1280x1024/g in above examples. Hope this helps! Cheers, Dariusz
