Comment 0 for bug 1483276

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 it could gain superuser privileges.

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/questions/659762/unable-to-launch-xdiagnose-through-gui-in-normal-way
