I haven't really had time to investigate but I've had an issue like |
| 14 |
this with my radeon card (using KMS) for a few weeks now. I'm on the |
| 15 |
4.4 upstream kernel. |

|
| 17 |
sddm and X11 in general work just fine, but if I try to switch to |
| 18 |
another virtual console the mouse cursor disappears but the X11 |
| 19 |
display otherwise remains in place. |

I suspect some kind of regression for radeon ended up in the stable |
| 22 |
queue. I'll have to take a closer look at my kernel config to see if |
| 23 |
perhaps it is now using a newer driver, but that seems unlikely as |
| 24 |
usually there aren't configuration changes in the middle of a stable |
| 25 |
series (and I've been on 4.4 for months now). |
