[SOLVED] ATI + 19" CRT resolution problem

heksagon · 2010-02-19 08:55:02

I have 19" CRT monitor and it's capable to display 1600x1200 resolution. In windows I can normally set resolution to 1600x1200 but in linux, xrandr allows me to set it only to 1280x1024. Actually only linux distribution wich has allowed me to set maximum resolution is debian lenny. ATM I use free ATI drivers. I can't find out what's the problem, so i tought if you coud help me.

[samu@gon ~]$ xrandr

I managed to change resolution simply by running 'cvt 1600 1200' to get correct modeline and 'xrandr --newmode "1600x1200_60.00" 161.00 1600 1712 1880 2160 1200 1203 1207 1245 -hsync +vsync' to add new mode to xrandr
