  Works perfectly
What works:

Worked perfectly till the laptop hardware failed in various small ways. (Unrelated to the software. Backlight burnt out and my backspace key wore out. The laptop saw a lot of use.)

Additional notes:

Can't really test much more on this since the laptop is about dead, or at least unusable as a laptop. Worked great up till then, though.
