YaST Installation via ssh
If you have another machine (a laptop, for example), you can use the traditional YaST installer with the default Tumbleweed ISO for a remote installation via ssh.
For that, boot the machine that you want to install with these additional boot parameters:
ssh=1 sshpassword=root
(or choose another root password that you like)
To get to this point, select “Installation” from the boot menu, then hit e to edit the boot command line and add ssh=1 sshpassword=root. Get out of that editor with F10, then boot with that entry.
The ISO will then boot up to the network setup, where it tells you the IP address that it received from your local DNS. You need that IP to log in via ssh:
Once it gets to this point, log in from your laptop or other machine; you can do that from the comfort of your KDE session that has all the accessibility features that you need. Use that password that you set with sshpassword=....
In my example, I started it from an Xfce4 terminal window, and I supplied the QT_SCALE_FACTOR directly:
I.e.
ssh -X root@192.168.178.189
Then accept the ssh fingerprint. Ignore that message “/usr/bin/xauth: file /root/.Xauthority does not exist”.
Now set the scale factor that you need:
export QT_SCALE_FACTOR=2.0
Fractional numbers like 1.5 or 1.75 may or may not work. 2.0 or 3.0 etc. are a safe bet.
Now start the installer:
yast.ssh
And you’ll get a really huge YaST window:
Notice: The keyboard layout from here will be temporarily (until the X11 or Wayland session restart) applied to your host system (the laptop) as well, so make sure you select the one that you are comfortable with.
Now click through the installation as usual.
