I've been fighting this exact same bug. I normally get to work and plug in a USB hub with two external keyboards, a mouse and a printer. I also plug in my external monitor. Only after plugging everything in, do I typically boot the laptop (Lenovo X220, i5). I upgraded to help test and have been fighting this bug ever since. I rather like using my external monitor so I continued to test various permutations. I have discovered that XFCE does not trigger this bug, although Unity and Gnome Shell do. Surprisingly, this is true even when I havexfwm set to use compositing.
Today, I discovered that if I don't plug in my external mouse/keyboards/printer stuff, I CAN successfully launch Unity with my external monitor, which is great because not using it was really annoying. (Hence my use of XFCE which I don't really like as much.) I attached my xorg.log from before my discovery. I will attach my xorg.log tomorrow from when I boot the system at work with my work around. Perhaps the difference will help figure out this bug. ** Attachment added: "Xorg.log" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/921236/+attachment/3124195/+files/Xorg.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/921236 Title: [12.04 Xorg, xserver 1.11.3] Dual monitor, after entering password, mouse pointer stuck on LHS of screen, no desktop.
