I had been using KDE 6 with some success until KDE 6.2 (and later) releases arrived. Now, I can logon and everything seems to start OK until after about 5 minutes when the log message tailer dies and Nagios sends me an email saying the desktop is down. Looking at the system messages I see:

etc...
I searched on Wayland, Nouveau and loops and discovered a mountain of grief. So is there any solution to this? (My current one, using XFCE + Kvantum is working worryingly well!) I saw some posts about people blocking the load of Nvidia and Nouveau drivers and using the Intel ones, but when I tried it nothing loaded but maybe I should have specified an Intel module somewhere? KDE 6.2 with the Xserver does start, but Plasma refuses to stay up; it works with a fresh user but it is too much work to reconfigure everything.
Any advice would be welcome. In November 1997 two things happened (amongst others): KDE Beta 2 was released, and I badly sprained my ankle and couldn't go to work for a week. The rest is history!
