I have now prevented Xmir from turning the physical display off under Unity8:
https://git.launchpad.net/~xmir-team/xorg- server/+git/xmir/commit/?id=9a508dc77fd68f8ba321e82ed0d7c36df1ddf745 However it appears Xmir will still blank the Xmir window to black. Sounds like we need to launch Xmir with additional options to prevent that... -p # screen-saver pattern duration (minutes) -s # screen-saver timeout (minutes) v video blanking for screen-saver -v screen-saver without video blanking ** Also affects: xorg-server (Ubuntu) Importance: Undecided Status: New ** Tags added: xmir ** Changed in: xorg-server (Ubuntu) Importance: Undecided => Medium ** Changed in: xorg-server (Ubuntu) Assignee: (unassigned) => Daniel van Vugt (vanvugt) ** Changed in: xorg-server (Ubuntu) Status: New => Fix Committed -- 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/1521403 Title: Unity8 crashes on suspend/standby with SIGSEGV in Screen::makeCurrent (./src/platforms/mirserver/screen.cpp:406) Status in Canonical System Image: In Progress Status in qtmir package in Ubuntu: In Progress Status in unity8 package in Ubuntu: Invalid Status in xorg-server package in Ubuntu: Fix Committed Bug description: The Ubuntu Error Tracker has been receiving reports about a problem regarding unity8.
