@arighi and @kleber-souza the issue persists in the test kernel. i915 error log attached.

The workaround in #82 helps with Jetbrains, and oibaf's ppa's mesa with KMS seems to make gnome terminal happy. Removing either lets me test this out. Still happy to test any proposed kernels :) ** Bug watch added: gitlab.freedesktop.org/mesa/mesa/issues #2026 https://gitlab.freedesktop.org/mesa/mesa/issues/2026 ** Attachment added: "/sys/class/drm/card0/error" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872001/+attachment/5367154/+files/i915.error.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872001 Title: 5.3.0-46-generic - i915 - frequent GPU hangs / resets rcs0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872001/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
