Bit of an odd one here and I’m not really sure if this is the right place to post it.
I recently installed Arch on one of my laptops with gnome and gdm and came across a problem with the authentication dialog.
When an application needs to request administrative privileges, usually, an authentication dialog should pop up prompting for authorization, however, this does not appear and whatever action the application was performing seems to go ahead without confirming authentication.
However, if I lock the gnome session with Super + L and then unlock it again, I can see the authentication prompt, but clicking either the authenticate or cancel buttons does nothing and the dialog remains open and stuck above all other content.
This seems to be an issue with any application that requires administrator authentication to perform an action. e.g. Changing the system keyboard layout in gnome settings or opening the pamac preferences window.
Today I’ve installed Endeavour OS on the same laptop and installed gnome and gdm and it does not have the same issue.
I’ve had a look at the /etc/sudoers file and the only difference is that the group with sudo enabled is wheel on Endeavour, but I set it up as sudo on the Arch install.
I’m guessing the Endeavour installer does something which I didn’t do when installing Arch manually, but I’m scratching my head as to what it could be and was wondering if this is a known problem which the Endeavour installer deals with?
I’ve also put a post up on the Arch forums (https://bbs.archlinux.org/viewtopic.php?id=248382) because at the end of the day, it’s a problem I have with Arch and not Endeavour, but I thought I’d post here to see if anyone had any ideas on why Endeavour does not present this problem.
