Black screen with a cursor after today's update

I just run the cachy os updater today. After the update I end up with a black screen with just cursor. The system goes through the boot loader, displays the CachyOS splash screen and then instead of showing the login window ends up just showing black screen with cursor.

I did upgrade to plasma-login-manager when the initial announcement came in, so it looks like today’s update is breaking something in plasma. Any help or advice? Is this being tracked somewhere else that I can follow along.

It’s been fixed. do an update.

not fixed for me I’ve updated twice now and had to roll back twice…

Not fixed for me, I fixed it by going to a newer version of the login manager: 6.6.1 via paru

CTRL+ALT+F3, login, paru -S cachyos-extra-v3/plasma-login-manager (or cachyos-extra-znver4)

(I had removed all the sddm stuff before, Thx Greatpj for the link)

I haven’t figured out a solution yet, but I did narrow it down to the plasma login manager, failing to load.. if you use Ctrl+Alt+F2 on that black screen it’ll open a terminal, login with username and password, and then type this to get to your desktop, /usr/lib/plasma-dbus-run-session-if-needed /usr/bin/startplasma-wayland which should get you to your desktop, and then you can figure things out. Not a fix, just a work around for now, I guess.

Me too. I’ve same problem. And I’ve to rollback to previous version.

Seems to be that for some reason the plasma-login-manager update to 6.6.1 isn’t being detected and therefore not being offered automatically for those who have it explicitly installed… when you check the current version it shows there being a newer version available, but it doesn’t seem to want to install it alongside the rest of the Plasma 6.6.1 packages for whatever reason.

So it’s not just me…

I just made an account just to comment about this issue. Ran an update in TTY and still not fixed.

I can’t even boot into my desktop session even with a snapshot or lts kernel. Not a great feeling as a new CachyOS user

Ran the ‘update’ plus the suggest paru -S cachyos-extra-v3/plasma-login-manager in last stable snapshot before reboot and now everything is good to go!

This is still not fixed, same issue. Had to roll back.

I did try sudo pacman -S plasma-login-manager it showed there is an update but the version numbers were same.

I am on R7 9800 platform so plasma-login-manager is installed from zen4 repos. I hope that helps.

for some reason pacman doesn’t have the upto date version of plasma-login-manager, after your update before reboot throw paru -S cachyos-extra-v3/plasma-login-manager into a konsole and it will get you the updated version.

This fixed it for me!!

i have to do that? im new, today i recently make the change from windows to cachyOS but i have the same problem: black screen with cursor

You can restore and just wait, it will be fixed.

You actually have a fully functioning system, just not a desktop manager. You can run from a terminal If you (ctrl atl f3) a terminal will launch…log in, then just type the name of the app you want to launch… steam for steam…. etc. It’s not a crashed system. It’s part of the fun?

Is it because option number 1 is older than option number 2?

If you run this command in the tty terminal, you can get to the desktop.. until this is fixed..

/usr/lib/plasma-dbus-run-session-if-needed /usr/bin/startplasma-wayland

i write your command, but send me again to a black screen with cursor

hehe i delete windows from my disk so i have to wait when they drop an update what fix this problem

i think this is quite common problem with rolling distro IMO

and it seems, the package (plasma-login-manager or something else) is not yet reached to your nearby mirror

my best advice for this (to prevent something like this again in near future)
avoid update your cachy if you find this kind of package in the list (and kinda know it’s need another core package that need to be upgraded as well)

qt related
plasma related
python related

it’s better to wait until several days, until all mirror repo synced with the latest package,

and the solution that i can think of is, roll back to your working snapshot, then wait a bit until all the package (atleast the important ones) listed in your arch-update list

this is kinda happens to me when we’re moving from qt5 to qt6 few months ago, so yeah just my little bit advice

hope it will resolved for everyone else soon :folded_hands:

thanks bro, i take ur advice, but how could i roll back a working snapshot? because i literally install today at 8pm in my country :sob:
