Hi!

How is VT switching normally handled when a DRI client is active?
Meaning, for example, switching from the X display to a virtual text console?

Looking in the i810 driver, it seems like the ringbuffer is flushed and
disabled until the X server calls EnterVT again, and AGP memory is
unbound. How is the client generally notified about this?

In the unichrome case, there seems to be a Z buffer problem, if not a
crash when the X display is restored. XvMC clients mostly likely to
hardlock the machine, or crash if they send their commands over AGP.

I'd much appreciate some advice or points to documentation how to handle
this.

Regards
Thomas
