Graphics driver timeout in Linux
In Windows, when the graphics (driver) crashes, there is a mechanism that allows for the graphics driver to recover and not take the OS down with it. I've read that there is a timer or a timeout for the graphics 'kernel' so that a graphics-crash does not result in having to reboot the machine to recover. I've seen this in action and the Windows OS stays up and running while the graphics gracefully restart and recover from a graphics crash. My question is: what is the Linux counterpart of that Windows mechanism? I've seen my Ubuntu_12.10 (with the fglrx-updates driver for the HD7770) lock up (the screen/UI) from time to time when the machine is crunching work-units using the GPU (via BOINC_v7.0.44) and I do not see Ubuntu_12.10 able to recover from the lock up, leaving me with no choice but to pull the plug. In doing the same thing under Windows7, the machine is spared from having to do that dirty re-start and I simply resume the interrupted work-units after the graphics (driver) recovers. I can safely attribute the lock up to a crashed graphics (driver) because the machine never have the lock-ups when not crunching work-units that use the GPU. Also, are instances of that graphics crash get to be handled by apport for crash reporting? Thanks.
