Are you using Wayland?
If yes, login using the option “Plasma / X11” and see if that works.

[hoiatl]

I did try that and same results

[hoiatl]

will look at thx

[arvidjaar]

You forgot to describe how you run YaST.

[hoiatl]

It doesnt matter if I start it from the command line or app launcher, its the same result

[hoiatl]

Also one of the “solutions” i found online was to boot to the tumbleweed dvd and run the repair option and reinstall the system files. This also did not work

here is another crazy issue I can run Qt programs as a normal user but whenever it needs root elevation it fails:

SuSE-Tumbleweed:/home/hoi # wireshark
** (wireshark:144402) 21:40:55.512396 [GUI CRITICAL] – This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: dxcb, xcb, eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx.

SuSE-Tumbleweed:/home/hoi # transmission

(transmission-gtk:146035): Gtk-WARNING **: 21:46:03.494: Failed to open display

what would cause root elevation to fail to open a gui app???

@hoiatl

How exactly you do “root elevation”?

P.S. Use preformatted text when posting computer output. Your posts are barely readable.

[panorain]

@hoiatl

root elevation

Elevated Privaledges

-Seasons Greetings

[hoiatl]

not sure what you are asking , but I put in the root password to elevate to root

[hoiatl]

I found this thread, now when I do what badshah400 advises it works. The yast2 gui appears. Im not sure why this is or how to fix. any help would be appreciated and may help other users

Help! Cannot start any apps from terminal!

Or do: kdesu kwrite /etc/sysconfig/themes and you will be prompted for the password.

(now my issue is that when i try to launch the program, in this case yast2 from the desktop as normal user I get the dialog box for the root password, after I put in the password the yast2 gui fails to appear)

also when do use su from command prompt and then launch the program, after I close the yast2 gui I get this message:

SuSE-Tumbleweed:/home/hoi # yast2
QStandardPaths: runtime directory ‘/run/user/1000’ is not owned by UID 0, but a directory permissions 0700 owned by UID 1000 GID 475

I am seeing exactly the same error when trying to run yast2 in Hyprland. There are some suggestions out there but didn’t tried. There is a command that one of the guru here posted not long ago and it works in hyprland. If I see the thread I will post it here.

@hoiatl

when do use su from command prompt

su keeps your user’s session environment which is what the error is about. Always use su - to switch to root user environment. If you also need to run Wayland programs:

su -w WAYLAND_DISPLAY -l root

@conram

I am seeing exactly the same error when trying to run yast2 in Hyprland.

And exactly like OP you do not explain how you run yast2 so it is impossible to guess what goes wrong.

[conram]

Hi, I used

su -c yast2, kdesu yast2, /usr/bin/xdg-su -c /sbin/yast2
su (root password) then as root yast2 with no joy

That’s in Hyprland, then I found your post in this thread:

How to run YaST GUI modules as native Wayland windows?

I tried the command you provided in a Plasma 6 Wayland session, and the GUI that opens for YaST as a result is still blurry and not Wayland-y: su - root -c sh -c "WAYLAND_DISPLAY=$XDG_RUNTIME_DIR/$WAYLAND_DISPLAY /usr/sbin/yast2" [image] Also xeyes is able to track my cursor when it passes over that window and it is the one in focus, so it’s an X11 window

That was the one that worked in Hyprland.
On a side note in wayfire the yast2 launcher doesn’t work. The command under the launcher is /usr/bin/xdg-su -c /sbin/yast2
but running su -c yast2 in the terminal, yast2 works.

[arvidjaar]

Does Hyprland have Xwayland (or any other X11 support)?
