Ran

systemctl list-unit-files --type service -all | grep -i scr

To find the name of the process

image

Then ran

systemctl start KlipperScreen

to start the process

image

Still does not appear to work

image

I restart the computer, nochange

Ran kiauth.sh again, this time did the update (it wasn't very old but I don't update unnecessarily because updates break things)

Removed klipperscreen

image

re-Installed klipperscreen

Still the error

[✓ OK] KlipperScreen successfully installed!

Further investigating this today

I've completely wiped this computer with fresh debian 12 and re-installed Kiauth

So it seems the X server is not starting when run

Here's the journalctl -f

So both KlipperScreen-start.sh and xinit run as user

and user has the permission to tty / dialout / video

Searching for "xf86OpenConsole: Cannot open virtual console 2 "

Leads to this reddit post about someone trying to install KlipperScreen

https://old.reddit.com/r/klippers/comments/uly2j6/cannot_open_virtual_console_2_and_any_commands_to/

They suggest running this command

root@klippa:~# cat /etc/X11/Xwrapper.config | grep allow
allowed_users=anybody

Ok, doesn't help, next the consensus of that thread is to add

needs_root_rights=yes

to

nano /etc/X11/Xwrapper.config

And immediately after saving this file klipper starts

Yet again, not running as root was the cause of all the problems !!

Problem solved for me thanks

(Well, touchscreen's not working but that's going to be a separate issue !)

Further notes:

As for the touchscreen, it was a bad microusb cable.

There is a permission somewhere that is wrong, I don't know where but

needs_root_rights=yes

which launches the x server as root

does fix it !

Further notes: As for the touchscreen, it was a bad microusb cable. There is a permission somewhere that is wrong, I don't know where but `needs_root_rights=yes` which launches the x server as root ![image](https://github.com/dw-0/kiauh/assets/10621885/07d6834d-beda-4b9f-87f2-cca58d6e5ce7) does fix it !

Can confirm. Have to do this every time when installing KlipperScreen on Ubuntu Server.

sudo bash -c "echo needs_root_rights=yes>>/etc/X11/Xwrapper.config"

That needs to be added to the install script.

It looks like this issue has to be fixed by KlipperScreen. In case of KlipperScreen KIAUH is just executing KlipperScreens own install script: https://github.com/dw-0/kiauh/blob/master/scripts/klipperscreen.sh#L60

So please head over to the KlipperScreen repository and open an issue there, if there does not exist one already.
