Comment 5 for bug 1841661

Actually, I'm not certain it is a duplicate of that one - this bug I think is a regression in eoan due to some change in the kernel between disco and eoan. Perhaps they are related though.

When I'm back from travelling I'll try to do a little bit of investigation (but I don't know anything about the DRM subsystem so bisecting is probably the best that I'm going to be able to achieve).
