Comment 18 for bug 570151

Today it happened three times in under an hour. The first two between displays one and two, the third - for the first time ever for me - between two and three. The only difference on the third occurrence was that I was attempting to play a Flash video (SWF) in VLC. I'm sure it's completely irrelevant, but since it happened (as I pressed Play) simultaneously with the first freeze between the second and third displays, it may be worth mentioning.

Well, after the last crash, I'm fed up. The loss of work is nearly rivaling the decrease in productivity I'll have if this keeps crashing versus giving up a display.... but I'm trying one final thing: KDE.

This evening I converted from Ubuntu to a bastardized version of Kubuntu (I just overlayed KDE, leaving everything else - including GDM - in place). I'm unsure it will be any better, but at the very least, the triple-head display worked right off the bat. And for me, coming from Mandr(ake|iva) after the better part of a decade, where it didn't work at all, I'm already impressed.

I'll give it a week and come back with my findings. If it repeats, I'll drop GDM in favor of KDM. If it doesn't, it may at least narrow it down to something in the upper-level DM layer.
