OP reported in https://lists.fedoraproject.org/archives/list/kde@xxxxxxxxxxxxxxxxxxxxxxx/thread/2NYJPSIU4NQU2JY72RBILFKEIUUOLVQI/ that he removed the nVidia drivers, but not how. > Have a look in /var/log/Xorg.0.log for error (EE) messages. Indeed there could be a clue there. AFAIK, proprietary nVidia drivers have no effect on the vttys. Since I never use proprietary drivers, I have no knowledge whether vttys for such users are any different from the others. AFAICT, all Intel, ATI/AMD and nouveau users depend on /dev/fb0 existing for expected behavior on the vttys. If the vttys also do not behave as expected, it's hard to believe OP's problem doesn't begin before SDDM or Plasma try to start. Maybe some other clue might be found by OP comparing one of mine to his, even though mine is not UEFI: # uname -a Linux big31 4.14.8-300.fc27.x86_64 #1 SMP Wed Dec 20 19:00:18 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux # lsmod | sort | grep veau drm 372736 4 nouveau,ttm,drm_kms_helper drm_kms_helper 167936 1 nouveau i2c_algo_bit 16384 1 nouveau mxm_wmi 16384 1 nouveau nouveau 1638400 1 ttm 98304 1 nouveau video 40960 1 nouveau wmi 24576 2 mxm_wmi,nouveau # ls -l /dev/fb* crw-rw---- 1 root video 29, 0 Jan 8 19:03 /dev/fb0 # fbset mode "1440x900" geometry 1440 900 1440 900 32 timings 0 0 0 0 0 0 0 accel true rgba 8/16,8/8,8/0,0/0 endmode # inxi -c0 -G # run from vtty3 Primary display adapter: #22 Graphics: Card: NVIDIA GT218 [GeForce 210] Display Server: X.org 1.19.5 drivers: modesetting (unloaded: fbdev,vesa) tty size: 180x56 Advanced Data: N/A for root out of X # hwinfo --gfxcard 22: PCI 100.0: 0300 VGA compatible controller (VGA) [Created at pci.378] Unique ID: VCu0.krMl9Oq+G5C Parent ID: vSkL.EAE6plTnV02 SysFS ID: /devices/pci0000:00/0000:00:01.0/0000:01:00.0 SysFS BusID: 0000:01:00.0 Hardware Class: graphics card Model: "nVidia GT218 [GeForce 210]" Vendor: pci 0x10de "nVidia Corporation" Device: pci 0x0a65 "GT218 [GeForce 210]" SubVendor: pci 0x3842 "eVga.com.
