--- Comment #3 from Paulo Dias <paulo.miguel.dias at gmail.com> ---
when i jumped from plasma to tty2 (alt-f2), the radeon dedicated card kicked in

the intel gpu reseted (error attached above)

Jan 28 03:06:12 hydra kernel: [drm] GPU hangs can indicate a bug anywhere in
the entire gfx stack, including userspace.
Jan 28 03:06:12 hydra kernel: [drm] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
Jan 28 03:06:12 hydra kernel: [drm] drm/i915 developers can then reassign to
the right component if it's not a kernel issue.
Jan 28 03:06:12 hydra kernel: [drm] The gpu crash dump is required to analyze
gpu hangs, so please always attach it.
