I’m trying to switch from Arch Arm to openSUSE Tumbleweed, to see how the support for aarch64 is. But I’m not getting any graphics acceleration working.
I’m using QEMU on macOS via UTM. Having said that, I don’t think the issue is from the setup, as acceleration works in both Arch and Fedora Rawhide with no configuration / extra packages outside of the DE.
I’m running Plasma X11, which was installed with
sudo zypper install \
patterns-kde-kde_plasma \
plasma6-session-x11
But kwin-x11 can’t start its compositor:
$ kwin_x11 --replace
kwin_core: Configured compositor not supported by Platform. Falling back to defaults
Here’s some logging info I hope is relevant:
KDE Support Information:
$ qdbus6 org.kde.KWin /KWin org.kde.KWin.supportInformation
KWin Support Information:
The following information should be used when requesting support on e.g. https://discuss.kde.org.
It provides information about the currently running instance, which options are used,
what OpenGL driver and which effects are running.
Please post the information provided underneath this introductory text to a paste bin service
like https://paste.kde.org instead of pasting into support threads.
