Comment # 1 on bug 987900 from Wolfgang Bauer

Please don't change the priority, this is for the developers/maintainers to
prioritize the bugs they are working on.

Regarding your problem:
I don't think Plasma/Wayland can work with the nvidia driver.

NVidia did add Wayland support to their driver a few months ago, but AFAICT
from Google it seems to only work with Weston as compositor and requires
special patches to Weston (provided by NVidia).
See
http://www.phoronix.com/scan.php?page=news_item&px=NVIDIA-Wayland-Discussion,
that's from April, but I don't think much has changed since then.

Please try again with nouveau.

If you don't want to uninstall nvidia, you can use a Krypton LiveCD instead:

In any case, Plasma/Wayland is still more or less experimental and unfinished.
I don't think we (openSUSE) really accept bug reports about it.
It should start though, and did here when I last tried (on Krypton) if the
graphics driver supports it.
