When installing the KDE version of Fedora 41 and then using RPMFusion and installing the following packages, the install completely bricks itself and is stuck on a black screen. I am not able to access any other TTY. SSH does not respond.
This might be the issue, then. But I don’t know how to recover the existing install?
I could do a livecd and then chroot, since the old kernel image isn’t working either. But this seems like something that should be more user-friendly IMO.
When there are issues with the nvidia driver you can always get into a system with ssh to investigate and fix. Many people are using KDE with nvidia without issue.
The fact that you cannot suggests that there is a deeper issue then nvidia drivers.
I wonder if there is a hardware issue that the KDE install is triggering that Gnome does not.
You might want to install memtest and run it overnight to check that you do not have an intermittent RAM problem.
Plymouth is used on all fedora spins and editions.
Kde or gnome does not start until a long time after plymouth has started.
But the exact set of services maybe different and change the timing of the boot sequence.
