I have also tested it in Ubuntu GNOME 16.04 with GNOME 3.19 and the issue is still present.
** Tags added: xenial ** Summary changed: - Unable to launch xdiagnose through the GUI in the normal way + Unable to launch xdiagnose through the Activities Overview in the normal way ** Description changed: I am in need of doing some diagnostics work with "xdiagnose", however when searching for it in the Activities Overview, and then clicking on it, absolutely nothing happens, when in the past it would ask me for my password so that I could run it as root. I looked further into this and tried running it in Terminal: xdiagnose And this was the output from the command: Error: Must run as superuser There was no output from the command: grep -r 'xdiagnose' ~/.local/share/applications And the output of this command "grep -r 'xdiagnose' /usr/share/applications" was: /usr/share/applications/xdiagnose.desktop:Name=xdiagnose /usr/share/applications/xdiagnose.desktop:Exec=pkexec xdiagnose /usr/share/applications/xdiagnose.desktop:Icon=/usr/share/xdiagnose/icons/microscope.svg /usr/share/applications/xdiagnose.desktop:X-Ubuntu-Gettext-Domain=xdiagnose The contents of the file is this: [Desktop Entry] Name=xdiagnose GenericName=Diagnose Graphics Issues Comment=X.org Diagnostic and Repair Utility Exec=pkexec xdiagnose Icon=/usr/share/xdiagnose/icons/microscope.svg Terminal=false Type=Application Categories=System;Settings; X-Ubuntu-Gettext-Domain=xdiagnose I have reinstalled it with "sudo apt-get install --reinstall xdiagnose", however this seems to have made no difference at all to anything. I have also attempted to launch another application via the Activities Overview that uses pkexec to start, and it works fine as normal. - This has been adapted from this AskUbuntu question (which I asked): - http://askubuntu.com/q/659762/364819 - --- **OS Information:** No LSB modules are available.
