Actually I think I've seen this before. One of the graphics drivers has run out of memory:
[ 198.184944] semiauto gnome-shell[2341]: Failed to allocate onscreen framebuffer for /dev/dri/card1: Failed to create dumb drm buffer: Cannot allocate memory [ 198.209428] semiauto gnome-shell[2341]: Failed to allocate onscreen framebuffer for /dev/dri/card1: Failed to create dumb drm buffer: Cannot allocate memory ...

But certainly gnome-shell shouldn't keep trying to run in this situation. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/2026790 Title: Slow refresh rate (5-6hz) on Display managed by gnome-shell To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2026790/+subscriptions -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
