Raised https://bugs.launchpad.net/ubuntu/+source/x11-xserver- utils/+bug/1724748 which I think is actually a dup of this existing bug. Here's what I'm seeing:
All (most?) gui apps fail to launch when using sudo, out-of-box, desktop 17.10 install. For example, gparted and virt-manager, which both require sudo, are not usable without a work-around. #### Out-of-box experience rbeisner@vistula:~⟫ sudo gedit No protocol specified Unable to init server: Could not connect: Connection refused (gedit:32146): Gtk-WARNING **: cannot open display: :0 rbeisner@vistula:~⟫ xhost access control enabled, only authorized clients can connect SI:localuser:rbeisner #### Work-around: rbeisner@vistula:~⟫ xhost si:localuser:root localuser:root being added to access control list rbeisner@vistula:~⟫ xhost access control enabled, only authorized clients can connect SI:localuser:root SI:localuser:rbeisner rbeisner@vistula:~⟫ sudo gedit rbeisner@vistula:~⟫ # (it launches ok) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xdiagnose in Ubuntu. https://bugs.launchpad.net/bugs/1713313 Title: Unable to launch pkexec'ed applications on Wayland session To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1713313/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
