do remember, I had them with F25.
Nevertheless, I have now removed all \*nvidia\* packages and I have
now 2 issues:
1. screen resolution is wrong in sddm
2. I still cannot open a plasma session with the following error in
[ 113.938502] sddm-helper: segfault at 0 ip 00007f3f74b96b6e sp
00007ffca1ba7300 error 4 in libc-2.26.so[7f3f74b1f000+1da000]
I could be wildly off base here. Are you UEFI/GPT booting? Is the resolution
wrong in both SDDM and in the vttys?
If yes to both, I'm suspicious these might actually be Grub trouble at the root.
I have only one system using UEFI/GPT, and it has no Fedora installations. And,
it's using Intel gfx, not NVidia or nouveau, and neither SDDM, nor even Plasma.
Here's the bug I reported:
video= on kernel cmdline ignored when loaded by grub2
If you don't read closely and think about it, you might not see the defective
kernel/bootloader relationship I suspect exists.
Can you avoid both problems by booting rescue media and choosing "boot from HD"
or "boot installed system"? If yes, it would seem to me to confirm bootloader
the root of the trouble.
I do have multiple F27 installations working fine with Plasma/KDM (all upgrades
from F26 from F25 from F24, etc. back to around F20 or so; none with SDDM IIRC;
on various incarnations of Intel, AMD & NVidia gfx), but they're all BIOS/MBR
booted from Grub Legacy.
