[PATCH v2] xfree86: after VT switching back, only enable previously enabled devices

[Peter Hutterer]

If a device was enabled before the VT switch, re-enabled it. Otherwise leave
it as is, there was probably a reason why it was disabled.

Changes: 
- set a flag in the pInfo struct instead of using a static array
