/* XF86DGA:
|
||||
* When DirectVideo mode is enabled you can no longer use 'normal' X
|
||||
* applications nor can you switch to a virtual console. Also, enabling
|
||||
* only works, if you have switched to the screen where the application
|
||||
* is running.
|
||||
* Some ways to debug this stuff are:
|
||||
* - A terminal connected to the serial port. Can be bought used for cheap.
|
||||
* (This is the method I am using.)
|
||||
* - Another machine connected over some kind of network.
