Programs unable to open display via sudo or pkexec (linssid not working)
#1
Linssid would be a useful tool for wireless network survey (at least 2.4 GHz) but although it installs it aborts on an error when run, apparently a problem with connecting to the display. This then precipitates additional errors, however the inability to connect to the display seems to be the actual issue. (Linssid uses pkexec to run with root privileges.) This appears to be a generic problem running any program as root via pkexec or sudo , for example a similar error occurs running "pkexec nemo" or "sudo nemo". I'm really not very familiar with Wayland, is there a way around this?

Code:
Invalid MIT-MAGIC-COOKIE-1 keyqt.qpa.xcb: could not connect to display :0
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

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

Zeb, I ran into this last night with gedit. It seems to be a deliberate policy of Wayland. I found these two links:
https://beamtic.com/sudo-and-guis
https://www.reddit.com/r/Fedora/comments...h_sudo_in/

Instead of sudo gedit, I'm using sudoedit as a workaround to edit my sources.list file.

Zeb, I found that sudo -EH gedit lets me open gedit as root. It is likely to work for most everything, I think.

Interesting. It works with gedit, but unfortunately does not work for linssid - the latter is invoked with the executable "linssid-pkexec" so it seems that program invokes pkexec internally, which clobbers the environment variables saved by sudo -EH. There is no option I can find to change that behavior.
