I guess even with a single display, multi-threaded apps like the web browser could still trigger this nouveau crash or similar by rendering from multiple threads.
There's a comment here suggesting the same crash might also happen in some processes like webbrowser-app even under Unity7: https://bugs.launchpad.net/ubuntu/+source/unity8-desktop-session/+bug/1595238/comments/15 which further supports the theory. Based on upstream's comment https://bugs.freedesktop.org/show_bug.cgi?id=92438#c39 I would expect nouveau to continue to crash under both multi-monitor and other multi- threaded rendering conditions (like webbrowser-app?). ** Summary changed: - Mir crashes on nouveau (nv50) in pushbuf_kref() especially with multiple monitors + Mir/Unity8 crashes on nouveau (nv50) in pushbuf_kref() especially with multiple monitors -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1553328 Title: Mir/Unity8 crashes on nouveau (nv50) in pushbuf_kref() especially with multiple monitors or opening the web browser app To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1553328/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
