Thought I tried that, which means there must be some locking / register restoration bugs around. /Thomas > Keith > --- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?

DRI and vt switching?
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.
