Mint 10 live CD won't boot in normal mode. Hard lockup with a black screen after GUI starts to load. Boot-up options have no effect on the point of lockup. The backlight remains off but half the LCD keeps cycling on&off;, horizontally split.
In failsafe mode it only boots to CLI. boot options like vga=773, vga=791, xforcevesa don't help either. startx reports an error along the lines of
(EE) VESA: kernel modesetting driver in use, refusing to load
(EE) No devices detected
Fatal server error: no screens found
....
xinit: No such file or directory (errno 2): unable to connect to X server
xinit: No such process (errno 3): Server error
