I haven't verified this yet, but it looks from the XOrg log like these systems are booting into dual head (with the SVideo out on head 2), 2128x800 total. That width over 2048 is probably what's causing the problem. I did "lose the mouse" on one, and suspected a "phantom head." I went to System Settings -> Display, it didn't show a second head but the whole desktop flickered (I suspect it turned the superfluos head off then.) I suspect it stored this in .config/monitors.xml, I'll check tomorrow if it'll now log into compiz, and if it's got some hotkey that may toggle that on and off.
I guess if that works out, then there's no real X bug; perhaps compiz should fall back to llvmpipe if it sees an an otherwise-working opengl implementation, but asks for a large texture and has it fail. Kudos to the compiz, Xorg, and llvmpipe developers btw... the CPU and RAM use were already decent in 14.04 but much lower now, and llvmpipe's actually reasonably fast too. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1643239 Title: Xorg crash on compiz login, with Intel 945 Status in xorg package in Ubuntu: New Bug description: I went to install Ubuntu (via systemback) onto some Dell D620s, and found "Gnome Flashback (compiz)" crashes back to login prompt, while "Gnome Flashback (Metacity)" does not. The attached logs reflect booting up, (attempting to) log in with Flashback (compiz) then logging in with Flashback (Metacity) to file a bug report. This may be chipset-specific, as I have several other rather antiquated systems: Intel 865-based (Compaq DC5000): Works. (Using LLVMPipe -- this chip is missing a few OpenGL features compiz requires.) Intel 915-based (Dell Inspiron 2200): Works. Intel 945-based (Dell Latitude D620): Crashes to login prompt (this is the machine in this bug report.) Intel 965-based (Dell Latitude 755?): Works. Intel G35-based (slightly newer Dell Latitude 755): Works. I can rule out software differences; since I knew Compiz worked on a 915, I assumed I'd screwed up my systemback LiveUSB somehow, and test- ran it on the D620, 2200, and one of the 755s, and it worked on the 2200 and 755. Left up to me, I'd categorize this as severity "low", I'm just setting these to Flashback Metacity and then stability seems fine.
