How to solve this?

How to solve, first do a search for Failed to read display number from pipe and you will see it’s a graphics problem. My next question is what happened to cause this? And for sure someone is going to ask you to provide more info as outlined here [HowTo] Request support

BG405 · 31 July 2025 17:40

Indeed! inxi -zv8 usually being the first one.

@MaMicha Have you tested with Wayland? It seems x11 is having more and more issues lately, since it’s not really being actively supported any more.

MaMicha · 31 July 2025 17:57

Thank you @BG405 ,

No, I did not and as I don’t reach the graphic screen, I have no idea how to switch (and how to switch back).

Good point; I’d somehow overlooked that little nugget this time.

Thanks for posting inxi info.

You could try setting SDDM to temporarily skip the login screen and autologin you into a Plasma Wayland session. This can be done by editing a file via a TTY session:

Open a TTY session & login as your normal user
Open the relevant text file in an editor as root:

sudo nano /etc/sddm.conf.d/kde_settings.conf

Make the following changes:

[Autologin]
Relogin=false
Session=plasmawayland
User=your_username

As an example, this is my /etc/sddm.conf.d/kde_settings.conf file - I have autologin active

[Autologin]
Relogin=false
Session=plasmawayland
User=scotty

[General]
HaltCommand=/usr/bin/systemctl poweroff
Numlock=on
RebootCommand=/usr/bin/systemctl reboot

[Theme]
Current=breath
CursorSize=28
CursorTheme=Bibata-Rainbow-Modern
Font=Noto Sans,10,-1,0,400,0,0,0,0,0,0,0,0,0,0,1

[Users]
MaximumUid=60513
MinimumUid=1000

Make sure you save the changes (Ctrl+X & then Y to confirm, or you can save before exiting with Ctrl+O & then exit with Ctrl+X).

After making the changes and saving the file, reboot. Hopefully you will now successfully enter a Plasma Wayland session.

Once you have a graphical desktop available, you might want to disable autologin & re-enable the login screen. The following is pre-prepared advice I often use when advising how to change Plasma from X11 to Wayland:

You can change your Plasma session from X11 to Wayland by selecting the session type at the login screen (Wayland is now KDE’s default for Plasma).

If you have set up autologin to skip the password screen, you can change to a Wayland session by opening System Settings → Colors & Themes → Login Screen (SDDM) → Behavior.

Note: As you had problems initially loading the SDDM screen when logging in, when on the System Settings → Colors & Themes → Login Screen (SDDM) page, you should make sure that your Login Screen is set to either “Breath” or “Breeze”. Custom themes, especially older ones, can cause problems.

Thank you @scotty65, your very detailed description is very helpful!
This is my actual /etc/sddm.conf.d/kde_settings.conf:

[Autologin]
Relogin=false
# ACTUAL Session=
# ACTUAL User=
Session=plasmawayland
User=myusername

[General]
HaltCommand=/usr/bin/systemctl poweroff
RebootCommand=/usr/bin/systemctl reboot

[Theme]
Current=breeze

[Users]
MaximumUid=60000
MinimumUid=100

I’m wondering, why there is no entry for Session=. Is it worth, to try X11 there first? If so, which syntax?
If not, I would modify the file as described above; any objections?

scotty65 · 1 August 2025 07:39

Because you are not using autologin. That entry only applies to autologin, which is normally set using the System Settings procedure I described earlier.

Probably not. There is no reason for you to be using X11, as you do have an Nvidia card. Wayland is now the default setting for Plasma, and where all the development at KDE is being focused on. You will likely find that your AMD system runs much better on Wayland than X11.

I can’t see any issues with using that file, but make sure you remove the commented lines from it:

The comments probably won’t affect SDDM, but I have occasionally seen config files where extra comment lines caused problems, so best to leave them out.

Edit: I should add that, if you are able to successfully get into a Plasma Wayland graphical environment using autologin, and then want to disable autologin, after doing so via System Settings → Colors & Themes → Login Screen (SDDM) → Behavior you should just log out (no need to reboot).

When the SDDM login screen (hopefully) reappears, make sure that you select Plasma Wayland (it could just be called Plasma as it is now KDE’s default) at the bottom of the screen before logging back in.

MaMicha · 1 August 2025 08:21

Thank you @scotty65, modified the file but same issue during boot:
Process core dumps and /var/log/Xorg.0.log having Fatal server error
Caught signal 11 (Segmentation fault). Server aborting, ref. my original posting.
What can I do?

scotty65 · 1 August 2025 11:00

Okay. For some reason it is still trying to start an X11 session. Let’s see if this works:

Log into a TTY session and run the command:

startplasma-wayland

Does that get you into a graphical environment?

MaMicha · 1 August 2025 15:34

Thanks a lot @scotty65!

This results in:

I’m starting to feel a little stumped on this one, so I’m not sure how much more assistance I will be able to provide.

However, this comment had me looking at your inxi output again:

Something I’ve just noticed is this part of the Graphics section:

You should have something there, even when running inxi in a TTY session.

Could you please log back into a TTY session & provide the output of:

inxi -G --display

Would you recommend to try sudo mhwd -r pci video-vesa?

brahma · 2 August 2025 15:47

when did this issue started? after an update/uninstall/install of something etc…?
you dont have vesa installed, its just listed as available…

MaMicha · 2 August 2025 16:31

Thank you @brahma!

After the last UPdate (2025-07-20).

You’re right but the colleagues there had the same facts (available, priority=0 etc.) and solved it by removing video-vesa …

brahma · 2 August 2025 16:59

so chroot:
manjaro-chroot -a
rerun update:
pacman-mirrors -f 5 && pacman -Syyu
if there are errors post the output here, if there are no errors and you are up to date, post output from:
ldconfig - (this should return nothing, if there are more than lets say 20 lines, dont bother to post, just let me know)
ls /etc/X11/* /etc/modprobe.d
pacman -Qm
mhwd -l && mhwd -li

MaMicha · 2 August 2025 17:33

Thank you @brahma,

Just to avoid a mistake: I can mount a drive in our network to write the output into a txt-file;
Which option: pacman -Syyu > '/media/drive/log.txt OR pacman -Syyu | tee ...

brahma · 2 August 2025 17:35

why would you do that?
you are in chroot, just copy the output here

MaMicha · 3 August 2025 07:13

Thanks a lot @brahma,

Sorry, I never used chroot before …
Now I tried manjaro-chroot -a from a virtual konsole and got: command not found.
Then I run MANJARO from a live-USB, these are the results:
