Unsupported Video Chipset - How do I force Low-Graphics mode?

Solution 1:

You could try adding one or more grub boot options such as "nomodeset" and "xforcevesa" - see my linked answer for help on how to do this.

You can try to use one of the following combinations:

nomodeset

xforcevesa

nomodeset xforcevesa

If you boot into recovery-mode you could create a file call xorg.conf:

sudo nano /etc/X11/xorg.conf

copy and paste the following information:

Section "Device"
    Identifier  "Configured Video Device"
    Driver      "fbdev"
EndSection

Section "Monitor"
    Identifier  "Configured Monitor"
EndSection

Section "Screen"
    Identifier  "Default Screen"
    Monitor     "Configured Monitor"
    Device      "Configured Video Device"
EndSection

This is the very basic framebuffer driver that fail safe uses.

Possibly if you change the text Driver "fbdev" to Driver "vesa" this should give you slightly better VESA type graphics.

This wiki page refers to the "trident" video driver. Since your card is a trident you may possibly be able to change the driver to "trident".

This wiki page refers to the "SiS" video driver which contains the "XGI Volari" name of your graphics card - possibly your card is this type in disguise and you may be able to change the driver to "SiS"
