The problem is that there is more than one .desktop file to start the hp-toolbox:
---------- [EMAIL PROTECTED]:~/printing/foomatic/lporg-site$ dpkg -S .desktop 2>&1 | grep '/hp' hplip: /usr/share/applications/hplip.desktop hplip: /usr/share/applications/hp-fab.desktop hplip: /usr/share/applications/hp-toolbox.desktop hplip: /usr/share/applications/hp-sendfax.desktop app-install-data: /usr/share/app-install/desktop/hplip.desktop hplip: /usr/share/applications/hplip-kubuntu.desktop [EMAIL PROTECTED]:~/printing/foomatic/lporg-site$ less /usr/share/app-install/desktop/hplip.desktop [EMAIL PROTECTED]:~/printing/foomatic/lporg-site$ ---------- in total my installation (Ubuntu standard + KDE) contains 4: ---------- [EMAIL PROTECTED]:~/printing/foomatic/lporg-site$ grep -i Exec `dpkg -S .desktop 2>&1 | grep '/hp' | cut -d ' ' -f 2` /usr/share/applications/hplip.desktop:Exec=/usr/bin/hp-toolbox /usr/share/applications/hp-fab.desktop:Exec=/bin/sh -c 'STARTED_FROM_MENU=yes /usr/bin/hp-fab' /usr/share/applications/hp-toolbox.desktop:Exec=/usr/bin/hp-toolbox /usr/share/applications/hp-sendfax.desktop:Exec=/usr/bin/hp-sendfax /usr/share/app-install/desktop/hplip.desktop:Exec=/usr/bin/hp-toolbox /usr/share/applications/hplip-kubuntu.desktop:Exec=/usr/bin/hp-toolbox [EMAIL PROTECTED]:~/printing/foomatic/lporg-site$ ---------- where 2 are already in the hplip package, and assuming that app-install- data makes also part of a Ubuntu live CD there are 3. Only the following files are deactivated with a "NoDisplay=true" directive: ---------- [EMAIL PROTECTED]:~/printing/foomatic/lporg-site$ grep -i nodisplay `dpkg -S .desktop 2>&1 | grep '/hp' | cut -d ' ' -f 2` /usr/share/applications/hp-fab.desktop:NoDisplay=true /usr/share/applications/hp-toolbox.desktop:NoDisplay=true /usr/share/applications/hp-sendfax.desktop:NoDisplay=true [EMAIL PROTECTED]:~/printing/foomatic/lporg-site$ --------- This means for fixing the bug two more .desktop files need to be removed or need the "NoDisplay=true" added: /usr/share/applications/hplip.desktop (package hplip) /usr/share/app-install/desktop/hplip.desktop (package app-install-data) It should also be taken care of /usr/share/applications/hplip-kubuntu.desktop in the hplip package. This file is there for Kubuntu (KDE-based) and should not generate an icon in Ubuntu, Xubuntu, or Edubuntu. As one of the candidates for the unwished icon is in the app-install- data package, I add this package to this bug report. -- HPLIP failed to start PyQt/Qt missing https://launchpad.net/bugs/67892 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
