Unable to open certain applications (Display :0)

Hi there, I updated some packages this afternoon and when I try to open some applications (like quartus and mysql-workbench) I get errors related to display :0, like on quartus:

 quartus: cannot connect to X server :0 

 
and on mysql-workbench:

 (mysql-workbench-bin:17296): Gtk-WARNING **: 01:50:27.620: cannot open display: :0 

When I try to run any xhost command I simply get

 xhost:  unable to open display ":0"`

even though the output of $DISPLAY is :0.

Any ideas of why this is happening, how to fix it and why it broke so suddenly? I`m running hyprland and already tried reinstalling it to no avail.
Thanks in advance.

Re: Unable to open certain applications (Display :0)

Does setting DISPLAY explicitly in hyprland.conf fix things?

Re: Unable to open certain applications (Display :0)

I updated some packages this afternoon

What packages and how, did you conduct a partial update?
This sounds as if xwayland cannot be started.
=> Check your xorg log

Re: Unable to open certain applications (Display :0)

A log from 4 months ago isn't so useful.

Re: Unable to open certain applications (Display :0)

https://wiki.archlinux.org/title/Xorg#General
The relevant log is likely in ~/.locale/share

Nothing in that list looks super-prone to break xwayland, though…

Re: Unable to open certain applications (Display :0)

I`ve got no log related to xorg on .local/share, however after a few reboots and tries the one on /var/log updated to this https://pastebin.com/a6cdzBtY

Re: Unable to open certain applications (Display :0)

That's from an X11 server that ran for ~40s w/o any problems - possibly your DM?

https://github.com/hyprwm/Hyprland/issues/6949 is related to the attached outputs…
I suspect the last time this works was w/ hyprland 42 and it broke w/ the last aquamarine and hyprland updates?

Re: Unable to open certain applications (Display :0)

I tried downgrading my entire system a month and still didn`t work, there is a workaround I found that if I start a xwayland window and then try to open the program they do open inside this window, although kinda poorly.
