wayland session and KDE still not working?

English Applications
1

Hello,

I have a system with a nvidia quadro K4200 graphic card using it with nouveau and DE is KDE.
I have two screens one on the DVI port and the other on the DP-1 port of the Nvidia card. (both at 1920*1080 extended to on virtual screen 3840 *1080).
Works perfectly with Xorg plasma KDE.
Kernel is

uname -a
Linux hpprol2 5.1.10-1-default #1 SMP Mon Jun 17 14:44:35 UTC 2019 (ad24342) x86_64 x86_64 x86_64 GNU/Linux

with xen.
When I try in the login the option plasma(wayland) or

  • it freezes immediately with a black screen (error in nouveau)
  • session opens but freezes after some seconds.(dumped cores + error in nouveau)
    Thereafter I need to to a hard reboot.
    In journalctl I have different dumped cores (in ksplashqml, thereafter in drkonqi and then the error in nouveau).

I wonder if wayland can work with this video card and the xen kernel?

Are you talking about running in a Guest or the HostOS?
Although AFAIIK Wayland should be supported in both environments, it will make a big difference what gpu driver is used.

also,
Although in this case wouldn’t likely make much diff, typically you’ll find more posts related to Xen in the Virtualization forum.

It is on the host. Not the VM. I cannot start it ==> the system freezes before

Yes but not sure if XEN has an impact. I plan to test without XEN after a backup.

Many thanks

I haven’t checked recently if there have been any changes, it used to be possible to boot to a non-Xen kernel in the standard Grub bootup menu.
If that’s still the case, no need to make major changes to your system.

I did some test with the standard kernel but the result are the same

  • sometime I can login but receive after few seconds a small window about a crash in ksplashqml. I can still then exit via Alt-Ctrl backspace
  • most times the screen goes black an all freezes and I need to to a hard reset.

in journalctl

there are thousands lines with same errors in nouveau. >:(

Is it possible that this card is not supported by wayland?
I have also see on thing: in plasma the primary screen is the DVI but in plasma wayland (when it works for some seconds) it is the DP-1 (display port)

For me it seems that wayland is still far to be ready.
