low resolution w/ radeon 9800 pro

KillerRoY · 05-01-2005, 05:03 AM

I just installed Slackware 10 (kernel 2.4.26), and I noticed that the highest resolution I can choose is 1024x768. How can I get a higher resolution? I tried installing new drivers (ati-fglrx-8.10.19-i486-1tsu.tgz) but then X would'nt start

You could use the gtf program to generate a mode line.
It should be at /usr/X11R6/bin/gtf

Here is how I could generate a mode line myself for 1280x1024 at 60 Hz.

Code:

jschiwal@matrix:~> gtf 1280 1024 60 -x

  # 1280x1024 @ 60.00 Hz (GTF) hsync: 63.60 kHz; pclk: 108.88 MHz
  Modeline "1280x1024_60.00"  108.88  1280 1360 1496 1712  1024 1025 1028 1060  -HSync +Vsync

Be carefull that you don't choose to high of a refresh rate or resolution. You don't want to damage the monitor.
