(Get the code!)
Thanks - if you can't boot RC2 that's fair enough, the rest of the info is useful anyway!
Your "random full screen flashes" - are you now getting
"(EE) intel(0): underrun on pipe A!" messages in the log? If so could be worth a look at https:/
Doesn't work that way with GLXgears, but yes, the currently suggested fixes mostly lose you some performance but gain you some stability. The only way to extract true performance is to get UXA and DRI2 stable, but as you know we're not there yet, we'll have to keep slugging away at the UXA bugs. At least we can: the first set of Windows drivers for my netbook were appalling and there was nothing I could do but wait for an update from the Microsoft gods.
Frame rates in games are a slightly better indicator, so if performance in your favourite game has dropped by half that's more meaningful that GLXgears dropping by half. I bet your game FPS hasn't come down quite so far though?
You are correct,
Option "EXAOptimizeMig
Option "MigrationHeuri
will be ignored if you have turned on UXA.
"(WW) intel(0): drmDropMaster failed: Unknown error 4294967295" is just a known warning you will see with kernels before 2.6.29 (it's to do with enabling DRI on multiple X servers on multiple VTs, which I therefore assume doesn't work on the .28 kernel, in fact I think I remember a bug complaining about that...)
