low resolution, new install of ubuntu 8.04, sis661 graphics chips


i have just installed Ubuntu 8.04 into an asus with p5s800-vm mother board, the graphics are by sis 661 chip set. the screen resolution cannot be set higher than 720x400. as i am using a 19inch monitor, 1024x768 would be better resolution, but this is unobtainable. it is as if drivers aren't loaded, when i look in "system-administration-hardware drivers" i get a message that there are no proprietary drivers in use.
if i need drivers, where do i find them and how do i install them?

Welcome to LQ gnome181!

Not sure if you can get that res
but, I dont think there are any proprietory drivers for sis?

anyway, go to system/admin/software sources and make sure you have all repos enabled

also, see here for other stuff to add to your repos
http://repogen.simplylinux.ch/

also, maybe you should try 9.04?
much more up to date

NOTE, my HP desktop a810n has sis 760 graphics and I cant even install ubuntu/debian as the screen locks up.

hopefully, others here can help too

try in a terminal dpkg-reconfigure xorg-xserver; probably needs root permissions (sudo)

Specify the correct refresh rates in /etc/X11/xorg.conf

Code:
Section "Monitor"
    Identifier     "Generic Monitor"
    HorizSync       27.0 - 96.0
    VertRefresh     50.0 - 160.0
    Option         "DPMS"
EndSection
Note that the numbers are examples and must match your monitor's capabilities (check the manual).

If you don't have a xorg.conf, you can create one and add the above. I'm however not sure if that will work without other additions to the file.

If you're in the graphical environment, enter the command gksudo gedit /etc/X11/xorg.conf in a terminal
If you're in a console, enter the command sudo nano /etc/X11/xorg.conf or sudo vi /etc/X11/xorg.conf; nano is probably the easier to use editor for a newbie.

As you've found out, you need root permissions to edit the file and sudo elevates your normal permissions to root permissions.

Problem solved. I couldn't get the refresh rates from the TV manual, but did some research on the net and found some one who had to edit his xorg.conf to get higher resolution with a new graphics card. He had added an extra mode, so I tried this:

Section "Screen"
Identifier "DefaultScreen"
Monitor "ConfiguredMonitor"
SubSection "Display"
Mode "1024x768"
Virtual 1024 768
EndSubSection
EndSection

Which is a combination of both answers, and it worked.

Thank you for your assistance.
