well. for a start I'd suggest keeping these two seperate. Not that it would matter much. Second, you want to run amdcccle GUI program, not amdxdg-su, which does EXACTLY what pkexec does, but amdxdg-su appears to invoke gksu/gksudo. Saying so, you need to change this in the file above: >> key="org.freedesktop.policykit.exec.path">/usr/bin/amdxdg-su -c >> amdccle</annotate> to the full path to amdcccle executable. key="org.freedesktop.policykit.exec.path">/usr/bin/amdcccle</annotate> This means you want to drop amdxdg-su everywhere in the instructions here which would make: > This is the same file I created the other day to get gparted to run from > menu.
