Have you tried without compiz/unity? Since ubuntu removed unity2d, they make it not very nice to test without compiz. I've installed an lxde desktop for it anyway. And the answer is no compositing, no trouble. Conversely, with compiz on: .xsession-errors is literally flooded with Mesa: User error: GL_INVALID_OPERATION in glReadBuffer(buffer=0x405) even without attaching the external monitor. Attaching the external monitor, I get failed to create drawable compiz (core) - Warn: glXCreatePixmap failed compiz (core) - Warn: Couldn't bind background pixmap 0x4c00001 to texture (gnome-settings-daemon:2024): color-plugin-WARNING **: unable to get EDID for xrandr-LVDS1: unable to get EDID for output On the other hand, the xorg log seems OK, just reporting the setting of the mode on the output pipe. Ok, back to the age old problem of mesa providing limited support for the extreme limitations of gen3. *** This bug has been marked as a duplicate of bug 42605 *** Thanks for the reply and for looking into this. As a matter of fact, I do not know if this is really a duplicate of 42605. That bug mentions problems with window sizes > 2048, which is not my case. I was aware of the limitations of gen3 with window sizes > 2048 since I had already been biten by them. Indeed when using 2 screens on gen3, I never put them side to side (e.g. with left-of, right-of), but I always put them one above the other (above, below), exactly to work around such limitation. If you look at my previous example, you will see that I have the VGA1 at 1024x768 below the LVDS1 which is 800 pixels high. This stays well within 2048. Furthermore the gen3 with two screens was working OK with unity/compiz before the upgrade to ubuntu 12.10. Now I do not know if the current issue is due to some change in compiz, or some change in mesa, or some change in the xorg infrastructure. I was trying to find an earlier bug which explicitly mentioned a hang with a >2048 GL composited desktop, the one I linked to was not the one I was looking for, but looked a reasonable subsitute. Definitely something has changed in the behaviour recently (last year or so) that has made the issue much worse. X, and the DDX, should work fine, it is a scenario that I irregularly test - and will happily fix any corner case you may find in the plain X setup. It's only when you throw a GL compositor into the mix that thinks break badly. yes, but my point is exactly that I do not have a desktop exceeding 2048 points in any dimension. the eeepc screen alone is 1024*600. when I add the external monitor at 1024*768 below it, I should get a virtual desktop as wide as 1024*1368 well inside the gen 3 limits. Ok, so not a duplicate of the 2k bug, sorry. I have no idea then. My first inclination is that since the basic mechanics work without compiz, is that it is still the DRI path screwing up. Is it possible for you to test with gnome-shell? (I don't have a ubuntu install on a gen3 platform so testing unity locally is a bit of a pain.) A look at a full debug log with sna would be useful to see what is happening during the freeze. Another issue that you also need an uptodate kernel to be sure you have the fix for the most recent pageflip-versus-modesetting display freeze.
