Bug Description
Description:
Both in Live CD Ubuntu system and in freshly installed Ubuntu system the only display resolution I was allowed to choose was 640x480@60Hz.
System specs:
PIII-866Mhz, 512MB Ram, Voodoo 3DFX 5000 64 MB, 40 GB HD.
Ubuntu 6.06 LTS (with GNOME)
Reproducing steps:
1. Start Ubuntu from live CD or fresh install.
2. Ubuntu is started with resolution 640x480@60Hz
3. Try to change resolution and freq. using System-
4. You won't be able to choose any other value for resolution and freq.
Work around:
1. Open /etc/X11/xorg.conf as root.
2. Go to section "Monitor"
3. Add following lines:
HorizSync 30-70
VertRefresh 50-160
4. Restart X11 or Ubuntu. You should get better default resolution and ability to change it to all allowed resolutions, color depths and frequencies.
You can fix this with Alternate+ Backspace
