Yes, thats the problem! xrandr gives me only one resolution: "1280x800 58.5", in LVDS. I added two resolutions; "800x600_58.50 58.5", and "640x480_58.50 58.5", I made them with "58.5" refreshrate as the original one. Here's how I did: > anton@anton ~ $ gtf 800 600 58.5 > > # 800x600 @ 58.50 Hz (GTF) hsync: 36.33 kHz; pclk: 37.20 MHz > Modeline "800x600_58.50" 37.20 800 832 912 1024 600 601 604 621 -HSync +Vsync > > anton@anton ~ $ xrandr --newmode "800x600_58.50" 37.20 800 832 912 1024 600 601 604 621 -HSync +Vsync > anton@anton ~ $ xrandr --addmode LVDS 800x600_58.50 > anton@anton ~ $ xrandr > Screen 0: minimum 320 x 200, current 1280 x 800, maximum 1280 x 1280 > VGA disconnected (normal left inverted right x axis y axis) > LVDS connected 1280x800+0+0 (normal left inverted right x axis y axis) 261mm x 163mm > 1280x800 58.5*+ > 800x600_58.50 58.5 > TV disconnected (normal left inverted right x axis y axis) > anton@anton ~ $ gtf 640 480 58.5 > > # 640x480 @ 58.50 Hz (GTF) hsync: 29.07 kHz; pclk: 23.26 MHz > Modeline "640x480_58.50" 23.26 640 656 720 800 480 481 484 497 -HSync +Vsync > > anton@anton ~ $ xrandr --newmode "640x480_58.50" 23.26 640 656 720 800 480 481 484 497 -HSync +Vsync > anton@anton ~ $ xrandr --addmode LVDS 640x480_58.50 > anton@anton ~ $ xrandr > Screen 0: minimum 320 x 200, current 1280 x 800, maximum 1280 x 1280 > VGA disconnected (normal left inverted right x axis y axis) > LVDS connected 1280x800+0+0 (normal left inverted right x axis y axis) 261mm x 163mm > 1280x800 58.5*+ > 800x600_58.50 58.5 > 640x480_58.50 58.5 > TV disconnected (normal left inverted right x axis y axis) > anton@anton ~ $ And now it works in fullscreen, without Virtual Desktop! Theres one some minor problems though: 1. When the game replaces the mouse pointer the original gets stuck at that position, while i can only move the "game pointer", so I have to push the pointer to the egde of the screen so it isnt visible when the switch occurs 2. I can not tab out of the game. Well, I can but then I cant get back into the game. But its alright now. Thanks.
