Yesterday my pc crashed during a system update and I had to reboot, which caused a problem in loading the kernel that I already figured out.
But when the system booted to the login screen and I thought it would be ok, after logging it only shows a black screen with the cursor.
The thing is, if I press F12 I get the shell terminal from which I can open firefox, and I’m using it right now to make this post, only the desktop is not showing, so I figure it may not be a problem in Nvidia’s driver
I don’t know where to begin solving this as I never tinkered with desktop environment, how can I begin to troubleshoot?
rerun update first:
sudo pacman -Syyu
Already did it
says there is nothing to do
so post output from:

formatting got weird for some reason but I guess it’s okay
Couldn’t my problem be with the desktop packages? How can I reinstall them?
could be some messed up plasma conf… can you enter system settings?
I don’t know the name of the program so I can start it with the terminal 
type systemsettings
I’m in it, the appearance selected configs are the same as before
so under global settings, click default, check also desktop layout, click apply - this will reset your theme
Theme changed from breath dark to breath
I think I may have to reinstall my DE packages
that will not probably help …open dolphin and rename the .cache folder to .cahce.bak then reboot
did you mean .cahce or .cache?
What it’s supposed to do?
yes cache.bak …
there are issues with plasma after update, like buggy plasma and what you have, so deleting cache could help with it
Still the same
What if I reinstalled plasma? Is that difficult?
you can do it:
sudo pacman -S plasma kio-extras sddm manjaro-kde-settings plasma5-themes-breath sddm-breath-theme
reboot
Everything was followed with “exists in filesystem”
And the last line was
Errors occurred, no packages were upgraded.
Can’t scroll up enough to see what happened the terminal was flooded with the packages that it tried to install
it should have reinstalled it …
run that command with overwrite:
sudo pacman -S plasma kio-extras sddm manjaro-kde-settings plasma5-themes-breath sddm-breath-theme --overwrite '*'
You did it my man
Took some time to load, probably because it was the first time loading after reinstall, but it’s all good now
thanks a lot for your time and patience!!
lets hope that it is fixed … but these exist in filesystem errors - you may have more of them …
try to install something, doesnt matter what, just to test if you can do it without issues …
