Opensuse Leap 15.5 – KDE Plasma on Wayland – Nvidia driver, Opera, Chromium, Libreoffice, StandBy

Some days ago I wrote a post on Eclipse and discussed fractional scaling of a selected monitor-screen in a Wayland-session. A reader has written to me and asked whether Wayland works on my system (Opensuse Leap 15.5) reasonably well otherwise.

Frankly, it is a bit like in the early days of KDE4. Wayland works, basically – and compared to Leap 15.4 the situation has improved significantly. But I wouldn’t use Wayland on Leap 15.5, yet, for any professional work under time pressure. During periods of hard work you need to trust your work environment to do what it is supposed to do. You should be able focus a 100% on your tasks – and not loose time with some unexpected glitches in your desktop environment.

However, I use Wayland these days when the risks are low. E.g. when writing blog posts or doing some information gathering on the Internet. Just to become prepared for the day when KDE Plasma switches to Wayland as the standard server for graphical applications. With this post I want to share some experiences with Wayland on a Leap 15.5 system – and give some hints regarding potential problems and workarounds.

Upgrade to Opensuse Leap 15.4 – I – a look at repositories, Nvidia, Vmware WS, KVM, Plasma widgets

we saw that an upgrade from Leap Opensuse 15.3 to Leap 15.4 is a relatively smooth operation. After the basic upgrade I wanted to look a bit at an interesting detail – namely (X)Wayland. And got surprised – positively and negatively. This post summarizes some of my experiences.

Nvidia and Wayland

For a long time it was almost impossible to use Wayland in combination with Nvidia and KDE. Which mostly was the fault of Nvidia. See an Heise article on this topic here. See also the experience of a Gnome user here – although I do not share his bad experience with a X11-based KDE Plasma on Nvidia. For years I have not seen a realistic chance for a productive use of Wayland on my PCs and laptops with Nvidia-cards. KDE PLasma did not work at all on Wayland. Also with Gnome I experienced terrible difficulties. But Nvidia has improved its support for Wayland significantly in 2022, starting with driver version 470. For Nvidia driver version 525 we would expect some stability.
