 |
|
Hello,
i like to give wayland a try.
Operating System: Gentoo Linux 2.15
KDE Plasma Version: 5.27.11
KDE Frameworks Version: 5.116.0
Qt Version: 5.15.14
Kernel Version: 6.6.38-gentoo (64-bit)
Graphics Platform: X11
unfortunately, my sddm "greeter" only shows Plasma X11 on the bottom left corner. There isn't even a "wayland" to choose that i could try.
| Code: | cat /etc/sddm.conf

It is really hard to say what is going on without more information about your system.
You need to verify that Wayland is actually installed.
Can you verify whether or not the following packages are installed?
| Code: | * dev-libs/plasma-wayland-protocols
Latest version available: 1.13.0
Latest version installed: 1.13.0
* dev-libs/wayland
Latest version available: 1.22.0

Latest version installed: 5.27.11
* x11-base/xwayland
Latest version available: 23.2.6
Latest version installed: 23.2.6 |
Also, switch to a virtual terminal and see if you can run a plasma wayland session manually:
| Code: | | /usr/bin/startplasma-wayland |

Please post your "emerge --info".
SDDM sets environment variables when logging in. To make sure none of those are set from the x session, creating a conflict (i.e. XDG_SESSION_TYPE=x11, etc.) disable the SDDM service.
Reboot.
When you are in the virtual terminal, log in as your user.
There are two things you can test. See if kwin is working:
| Code: | | XDG_SESSION_TYPE=wayland dbus-run-session kwin_wayland --exit-with-session=konsole |
You will see a black box in the middle of the screen. This will also give you some output.
The other command is similar to the one that you already tried, but will launch a dbus session first and set environment variable:
| Code: | | XDG_SESSION_TYPE=wayland dbus-run-session startplasma-wayland |
(You can save the above commands in a bash file in your home directory and run them that way rather than trying to type them.)
If you are using grub, make sure /etc/default/grub has the option "nvidia_drm.modeset=1". Example:
| Code: |
GRUB_CMDLINE_LINUX_DEFAULT="quiet loglevel=0 nvidia_drm.modeset=1" |
Update grub and reboot. |
