- Do not allow openning /dev/sysmouse multiple times. When there are
multiple instances of moused(8) and Xorg mouse driver
opens /dev/sysmouse multiple times, Xorg server gets confused badly,
e.g., losing input events, waiting for already processed events, etc.
- Really fix laptop brightness control. The previous commit didn't
fix IBM and Sony laptops. Pointyhat to me, again.
