Unable to set screen resolution to higher than 1024x768 in Ubuntu LivsCD

[sanjeevdas at yahoo.com]

Hi All,

I am using the Ubuntu 4.10 Livd CD on my machine.
Although the monitor (21 inch Dell Sony Trinitron,
Matrox Millennium G400 AGP graphics card) is capable
of higher resolutions, the gnome screen resolution GUI
allows me to use 1024x768 as the highest. Is there a
way to use a higher resolution. Maybe by changing the
X11 config files manually?

thanks

Sanjeev
