My gnome-system-tools menu items use gksu, as described above. However, this stops them from working. I get the same problem that is described in https://launchpad.net/distros/ubuntu/+source/sudo/+bug/5100 - it tells me that my password is invalid. Running, for example, disks-admin from a root shell gives me exactly the same error. However, running disks-admin from a normal user shell works perfectly - it asks me for my password, and then runs fine.
This would seem to indicate that disks-admin does its own sudo'ing, and doesn't require gksu or gksudo to elevate its permissions for it? This would explain the problem, too - gksu becomes root, and runs disks- admin, which then tries to use the root user's password, which of course does not exist. Should these desktop files be altered to remove the 'gksu' from the launch command? -- menu launcher (gksu.desktop) still uses gksudo instead of gksu https://launchpad.net/bugs/30057 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
