XMir 1.0 (the old Xorg extension) is now deprecated and is not being maintained or fixed. It is replaced by the new 'Xmir' binary (package 'xmir') introduced in Ubuntu 15.10 wily.
Is there any way to reproduce this bug without the old Xmir? ** Changed in: mir Status: Triaged => Incomplete ** Changed in: xorg-server (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1217821 Title: Xmir doesn't start with MUXed Intel/ATi hybrid graphics Status in Mir: Incomplete Status in xorg-server package in Ubuntu: Incomplete Bug description: I've an Acer 4820TG notebook with MUXed Intel + ATi cards, and I can select which card to use via BIOS setting or somewhat dynamically using vgaswitcheroo. In case I set the notebook in dynamic mode on the bios, so that I've both the VGA cards available, XMir doesn't start, and I'm getting the X fallback session instead of lightdm. If I instead add an upstart job to force one of the cards to turn off early on the boot, it works instead.
