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 Touch seeded packages, which is subscribed to policykit-1 in Ubuntu. https://bugs.launchpad.net/bugs/1713313 Title: Unable to launch pkexec'ed applications on Wayland session Status in apport package in Ubuntu: New Status in apt-offline package in Ubuntu: New Status in backintime package in Ubuntu: Confirmed Status in budgie-welcome package in Ubuntu: Invalid Status in caja-admin package in Ubuntu: New Status in cinnamon package in Ubuntu: Invalid Status in ettercap package in Ubuntu: Confirmed Status in gdebi package in Ubuntu: Confirmed Status in gnunet-gtk package in Ubuntu: Confirmed Status in gparted package in Ubuntu: Invalid Status in gui-ufw package in Ubuntu: Confirmed Status in guidedog package in Ubuntu: New Status in hplip package in Ubuntu: Confirmed Status in italc package in Ubuntu: New Status in laptop-mode-tools package in Ubuntu: New Status in lightdm-gtk-greeter-settings package in Ubuntu: Confirmed Status in nautilus-admin package in Ubuntu: New Status in needrestart-session package in Ubuntu: Confirmed Status in nemo package in Ubuntu: Confirmed Status in policykit-1 package in Ubuntu: Invalid Status in scanmem package in Ubuntu: New Status in scap-workbench package in Ubuntu: Confirmed Status in sirikali package in Ubuntu: New Status in synaptic package in Ubuntu: Confirmed Status in thunar package in Ubuntu: New Status in tuned package in Ubuntu: New Status in ubuntustudio-controls package in Ubuntu: New Status in ubuntustudio-default-settings package in Ubuntu: Invalid Status in update-notifier package in Ubuntu: New Status in xdiagnose package in Ubuntu: Confirmed Status in xubuntu-default-settings package in Ubuntu: Invalid Status in zulucrypt package in Ubuntu: Fix Released Bug description: Posting here what gnome says about porting to wayland, and their tests: GNOME Applications under Wayland GTK+ has a Wayland backend. If it was enabled at compile-time, you can run a GTK+ application under Wayland simply by: GDK_BACKEND=wayland gnome-calculator Applications that use Clutter or clutter-gtk also need the Clutter Wayland backend enabled: GDK_BACKEND=wayland CLUTTER_BACKEND=wayland cheese https://wiki.gnome.org/Initiatives/Wayland/Applications ======> so hope the settings are well set at compile time; maybe a rebuilt to get sure all apps are ok. ******************************************************************************************************************************************** Steps to reproduce: 1. Install Ubuntu 17.10 2. Install backintime-qt4 or gparted application from above list (full may be acquired from https://codesearch.debian.net/search?q=pkexec+filetype%3Adesktop+path%3A*%2Fapplications%2F*&perpkg=1&page=4 ) 3a. Try to launch backintime-qt4 from shortcut "Back In Time (root)" (located in /usr/share/applications/backintime-qt4-root.desktop, it uses pkexec ($ cat /usr/share/applications/backintime-qt4-root.desktop | grep Exec Exec=pkexec backintime-qt4) 3b. Try to launch Gparted from shortcut "GParted" (located in /usr/share/applications/gparted.desktop, it uses gparted-pkexec) 4a.1. Back In Time does not start from GUI. 4a.2. Back In Time shows error message in console: 4b. gparted-pkexec does not start, reports error $ gparted-pkexec Created symlink /run/systemd/system/-.mount → /dev/null.
