# SVGAlib driver

This is a driver for Linux SVGAlib. I really like this driver, because I much prefer full screen zooming instead of a small 320x320 window in X11. It was one of the first drivers for XaoS and is fully featured. The following problems can occur:

XaoS doesn't initialize graphics mode
  when started under users other than root SVGAlib requires root privileges to directly access the hardware. When you really want to start XaoS as a normal user, enable the suid bit (`chmod +s`) at XaoS executable. note that I take care to disable all security holes caused by this bit so I believe it is safe.
Mouse doesn't work
Screen is blank at higher resolutions
  Both this problems are probably caused by misconfiguration of SVGAlib. Please configure it in `etc/vga/libvga.cong` or `/usr/local/lib/libvga.conf` GPM can also cause problems. Try to kill it before starting XaoS.
When I switch console I can't switch back
  This is another typical SVGAlib bug. Try to hold `F` key longer than `alt`. It helps on my computer. On older SVGAlib there was a famous "enter bug" that caused a crash after pressing enter. Try to update to a newer release.

SVGAlib driver was written by Jan Hubicka, 1997.
