For what it's worth I'm getting a very similar issue on Linux Mint Cinnamon after the update from 19.1 to 19.2. The error is:
cinnamon: ../src/gallium/drivers/radeonsi/si_state_viewport.c:239: si_emit_guardband: Assertion `left <= -1 && top <= -1 && right >= 1 && bottom >= 1' failed. I've found that the positions of monitors in a dual monitor setup dictates whether or not the DE crashes on startup. See this thread: https://github.com/linuxmint/cinnamon/issues/8754 Hopefully the problem is identical for you guys and a patch can fix both issues at once. ** Bug watch added: github.com/linuxmint/cinnamon/issues #8754 https://github.com/linuxmint/cinnamon/issues/8754 ** Also affects: cinnamon (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1837087 Title: gnome-shell crashed with assertion failure ../src/gallium/drivers/radeonsi/si_state_viewport.c:239: si_emit_guardband: Assertion `left <= -1 && top <= -1 && right >= 1 && bottom >= 1' failed.
