** Also affects: linux (Ubuntu)
Importance: Undecided
Status: New
** Description changed:
I was trying to diagnose a bug with workspaces and moving around from
desktop to desktop when the screen suddenly froze (no corruption, just
stopped updating). Could not vt switch, but could ssh in and file this
bug report from the console. Looking at dmesg appears to be a drm
fault.
