I'm not sure what you mean by missing information - I tried the other four boot options in the article:
* noapic Same as before, except that IRQ #11 was disabled instead of 16. Same problem occurs with windows disappearing, seemingly random (works sometimes, doesn't work other times). * pci=routeirq Same as before, IRQ #16 was disabled. Same problem occurs with windows disappearing, seemingly random (works sometimes, doesn't work other times). * pci=noacpi Same as before, except that IRQ #11 was disabled instead of 16. Same problem occurs with windows disappearing, seemingly random (works sometimes, doesn't work other times). * acpi=off Second screen didn't appear and the single screen that did had very poor resolution. No bug because I didn't have dual screens. * irqpoll As I described before, the same as without it - the windows appear sometimes correctly and disappear at other times. Sometimes the windows stay across multiple locks, sometimes they don't. Let me know if you want something else - also, I'll note that I'm not experiencing any of the IRQ problem symptoms described in the article, like hardware devices not working, multiple hardware device problems, or system hangs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1257327 Title: Ubuntu 13.10 dual monitor screen lock causes windows to disappear off- screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1257327/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
