PC freezes after login after installing KDE

Hello, I just installed the desktop-kde bundle and rebooted my PC. Now I am welcomed by the login screen but when I enter my password and try to login whether on Plasma or Gnome the laptop just shows me the login screen again and freezes completely (cannot even access the terminal). Something must be conflicting but what is it?

I remember that you had NVIDIA Optimus but have you configured that for KDE?

Oh no, I didn’t do anything, I just installed the bundle and restarted the PC. :slight_smile:

Well aside from the NVIDIA driver, you may need to disable gdm and enable sddm in systemd.

Could you elaborate on that please? I run systemctl disable gdm and systemctl enable sddm. I have the exact same behaviour.

But have you configured sddm as you configured gdm with Optimus support?

@Qushy I’ve experienced something similar with Intel graphics + kernel 5.2 and plasma. I’m not sure if it’s the same issue, but if you’re running the Plasma session powered by Intel graphics, please try adding i915.enable_psr=0 to the kernel command line. There was an i915 bug in kernel 5.2 with fix already merged, but it seems Plasma can trigger a different one quite easily.

OK I wrote the following in /etc/sddm.conf and now the PC boots into Plasma randomly without asking for a password:

[Autologin]
Session=plasma.desktop
User=<username>

But I think I’ve pinned down the problem to startx looking in /usr/share/X11/xorg.conf.d and not finding the correct .conf files so it can’t find a screen. /usr/share/X11/xorg.conf.d contains some AMD conf files but I’m on NVidia Optimus. How can I fix that? I’ve looked online and haven’t found a solution yet.

EDIT: Ok, I’ve tried a lot of things, the problem is that startx completely freezes the PC with “Screens found but none have a usable configuration” and Xorg -configure fails with “Number of created screens does not match number of detected devices”.

Post the files you mentioned here

I’m afraid I can’t do that, I only have a Manjaro Deepin Live USB and it won’t connect to the internet. There is a line also reading “Failed to acquire modesetting permission”. I think this is causing all the fuss.

Did you update the system first before adding bundle?
and I am running plasma didn’t have to enable or disable anything , just install kde bundle and reboot

Oh no I haven’t updated the system before adding the bundle, however I managed to boot in Plasma randomly one time and updated then.

Ok the system randomly booted in Plasma again. Here’s the /var/log/Xorg.1.log:

Hello my friend.
Something like that happened to me in linux mint. The problem was that when I installed an app, there seemed to be corrupt and uninstalled dependencies and this was the problem. The solution was to enter console mode (not desktop) and execute the following command:

apt-get dist-upgrade

It is worth trying the following commands later:

apt-get autoremove

apt-get autoclean

apt-get update

apt-get -f install

I think these commands have to do with Debian and not Clear Linux, but thanks for the suggestions anyway. :smiley:

So what I meant by configuring sddm as you configured gdm is to modify /usr/share/sddm/scripts/Xsetup instead of creating /usr/local/share/optimus.desktop.

According to the guide, this is what it’s needed for sddm, which is the default desktop manager for kde.

So have you done this?

I’m trying to setup KDE Plasma as well, and got exacttly the same issues (laptop with Nvidia card). While following the Medium guide works for GNOME, in KDE it shows the login screen but when entering the password it just kicks me out.

UPDATE
I tried following the Arch Linux NVIDIA Optimus guide to setup Plasma, using SSDM, but got no luck. Only solution has been removing the desktop-kde bundle at once, since I couldn’t even use GNOME anymore

UPDATE 2
So, the problem I have now is this: the KDE graphical login screen shows up, and I can choose a bunch of DEs (GNOME, Plasma, Weston, on Xorg or Wayland). I tried to launch all of them but the same thing happens with every one: you enter the password, the screen goes black for a split second, then it kicks you back again to the login screen. Here are the errros from the Xorg log:

@doct0rHu any ideas to solve this?

UPDATE:

It looks like that, with the latest CL build and the latest Nvidia drivers, everything is working as it should. Plasma is very cool, although it seems quite bugged (themes won’t install and stuff like that). But this seems more of a problem on Plasma side

Hey.

I’m seeing a lot of the above mentioned issues on a pure intel machine so some of your issues may not be entirely Nvidia related.

For me to get a stable KDE experience I had to remove everything gnome including gdm (had both display managers running) AND NOT select the wayland session.

[edit] typo

Sorry for the late reply. I was very busy since my school started.

Recently Gnome cannot starts with NVIDIA driver, so I’m wondering it might also affect you.

Let’s wait until this is fixed and then try Optimus.
