Ubuntu

screen resolution max at 800x600

Asked by edno99

I'm running 8.10, fully updated, but I can't get a resolution higher than 800x600. In my monitor resolution settings, the display is set to unknown, but I'm using a Sony SDM-S75A TFT with a maximum resolution of 1280x1024.
I have a feeling that the driver for the video card may not be right - SiS recommend going to this place to download something... http://www.winischhofer.eu/linuxsispart4.shtml#download
but I'm unsure what to download! Hopefully these terminal command outputs will help:

Video card:

lspci | grep -i vga
01:00.0 VGA compatible controller: Silicon Integrated Systems [SiS] 661/741/760 PCI/AGP or 662/761Gx PCIE VGA Display Adapter

Hi

Try the following:

1: cp the file /etc/X11/xorg.conf to /etc/X11/xorg.conf.bak
2: Edit the file /etc/X11/xorg.conf: sudo gedit /etc/X11/xorg.conf
3: Change the screen section as follows:

Section "Screen"
 Identifier "Default Screen"
 Device "nVidia Corporation NV5M64 [RIVA TNT2 Model 64/Model 64 Pro]"
 Monitor "Generic Monitor"
 DefaultDepth 24
        SubSection "Display"
                   Modes "1280x800" (choose your resolution)
        EndSubSection
EndSection

4: Save the file
5: Restart the system

Hope it helps
Peter
