Kernel 4.14, Xfce.
All fine: I had to do the usual system maintenances to check pac files and rebuild AUR packages; however, now in the journal logs, I see a new warning: systemd: -.slice: Failed to migrate controller cgroups from /firstname.lastname@example.org, ignoring: Permission denied
I had a small issue, the bpython interpreter got uninstalled for some reasons, so I tried to reinstall it, there was a few file conflicts but removing them was enough to solve it, everything is back to normal now.
Also there is something I find weird :
I had nvidia 450 driver installed so far, and when I run mhwd -l, it’s not listed anymore in the avaiable drivers, which means it should have been uninstalled, but nvidia-smi tells me that 450 is still here, I also did a short test with pytorch and everything works fine, any explanation ?
Firefox is unbearably slow and is consuming 100% CPU, I can barely type this post
games are running at slide show speed
GUI is noticeable slow(ish), too
(glxgears reports 400 fps, though)
So… I have no idea what to do now to fix or revert everything as it was before the update (previous 5.4 + nvidia-390xx). What I tried:
Removed nvidia-390xx and switched no Nouveau just to see if it’s usable these days (it is not - way faster than my current situation, but still, like, 3 times slower than Nvidia before the update)
Switched back to Nvidia drivers (sudo mhwd -a pci nonfree 0300) - everything is slow again.
Any advice? I’m in serious trouble now, sorry for begging, but I really, really need an advice
