Hi Boris. I think the tool you're looking for is xrandr. For example, on my machine, I can get a list of possible resolutions as follows: [EMAIL PROTECTED]:~$ xrandr SZ: Pixels Physical Refresh *0 1280 x 1024 ( 342mm x 271mm ) *75 60 1 1280 x 960 ( 342mm x 271mm ) 60 2 1024 x 768 ( 342mm x 271mm ) 75 70 60 3 800 x 600 ( 342mm x 271mm ) 75 72 60 56 4 1280 x 800 ( 342mm x 271mm ) 60 5 1152 x 864 ( 342mm x 271mm ) 75 6 1280 x 768 ( 342mm x 271mm ) 60 7 832 x 624 ( 342mm x 271mm ) 75 8 640 x 512 ( 342mm x 271mm ) 75 60 9 720 x 450 ( 342mm x 271mm ) 60 10 640 x 480 ( 342mm x 271mm ) 75 73 60 11 640 x 400 ( 342mm x 271mm ) 60 12 576 x 432 ( 342mm x 271mm ) 75 13 640 x 384 ( 342mm x 271mm ) 60 14 512 x 384 ( 342mm x 271mm ) 75 70 60 15 416 x 312 ( 342mm x 271mm ) 75 16 400 x 300 ( 342mm x 271mm ) 75 72 60 56 17 320 x 240 ( 342mm x 271mm ) 75 73 60 Current rotation - normal Current reflection - none Rotations possible - normal Reflections possible - none and then choose a different resolution by running: [EMAIL PROTECTED]:~$ xrandr -s 800x600 The xrandr command makes use of the "rotate and resize" (i.e. RandR) extension of X which is relatively new (so I'm not sure whether your Redhat 9 system will have it without additional upgrades). A fairly good introduction to xrandr can be found here: http://www.debian-administration.org/articles/201 Hope that helps.
