Description
In our SUSE's SLE 15 beta tseting, we received quite some GNOME issues caused by Wayland + mgag200 combination. Quote:
"SLES 15 Beta 5. The gnome desktop keyboard and mouse on the server is extremely slow responding with all Lenovo systems I have tried. (The most recent systems I have tested are ST550 and x3650 M5). This includes several new purley-based systems and older broadwell/haswell systems as well. All of these system use Matrox graphics controllers. "
"With sles15 beta4 I am observing both functionality and performance issues on the HPE ilo graphical console when graphical.target is chosen. Interaction is very sluggish, mouse very slow to follow physical mouse movement, keyboard is subject to rapid, repeated keystrokes. For example, I noticed the sluggishness, opened a terminal window, intending to type "ps" and got "pppppppps". The first character typed after a pause seems most likely to repeat. "
"sles 15 beta 5 gnome keyboard and mouse are extremely slow with Matrox graphics controllers"
So it should make sense to disable wayland by now on those chips using similar code path in:
bgo#789081 gdm should never try wayland on Cirrus chipset
