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:
If you boot into recovery-mode you could create a file call
sudo nano /etc/X11/xorg.conf
copy and paste the following information:
Identifier "Configured Video Device"
Identifier "Configured Monitor"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
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"
