A week ago I had updated my KDE Neon Testing without problem to 6.6.5.
Today May 31 I updated again: booting then took a long time and autologin didn’t work and left me at the login screen.
I entered my password and after a while the login screen appeared again.
I did ctrl-alt-F6 to go to tty: I logged in as my user with my password. I did some simple commands. Then I did a sudo command and it didn’t accept my password.
I rebooted in recovery and with root I reset my password.
In normal mode in tty then I could run the sudo command.
But I still can’t get past the login screen.
In recovery mode I did the dpkg check.
I did “pkcon refresh; pkcon -v update” but no new updates.
Then on the login screen I changed from wayland to X11 and then I was able to login into plasma!
But it’s X11!
Apparently I am now on 6.7 beta 2.
Anybody that can fix wayland now?
If I have time I will file a bug.

with command “journalctl -xe | less” I see a lot of coredump lines and unit services getting dead.
“journalctl -xe” also shows lines like
org.kde.powerdevil.discretegpuhelper[3318]: Detected locale "C" with character encoding "ANSI_X3.4-1968", which is not UTF-8.
Qt depends on a UTF-8 locale, and has switched to "C.UTF-8" instead.
But command locale in my terminal doesn’t show C nor ANSI_X3.4-1968.

After trying various changes to let my system run only with opengl and not
vulkan, Gemini concluded that my gpu card is too old for the latest kde
wayland.
"your GeForce GT 630 simply lacks the hardware architecture required to
run modern Wayland protocols via the open-source nouveau driver.When you
forced KWin to look at card0, it still threw the Device or resource busy
error.
This happens because the legacy nouveau driver lacks modern atomic
mode-setting capabilities for your older chipset. When kwin_wayland
attempts to query the card, the kernel module cannot fulfill the
request, locks up, and marks the device as busy.Remaining on Plasma
X11 is the correct and most stable choice for your hardware setup."
In the near future I will need a lot of time to buy a new computer to
install KDE Linux on it and to configure it.
