Yes it is. I've been looking for someone to help out here and when I saw that someone had a Mint problem, I was like "Yes! Something I can surely help someone out with!" As it turns out though... it was quite a struggle to figure this out. I did eventually manage to make it happen on my machine though, so hopefully it will work for you. It turns out that it is actually hard coded into the mintMenu program. Ready to get your hands dirty?
First, you need to find where mintMenu is installed. On my machine, it was at:
If you don't find it there, open up a terminal and type:
find -name "mintMenu"
Hopefully you should find the directory that it is installed to by then. Now, cd into that directory by typing something like this into the terminal:
or wherever your installation may be. Then type in:
gksudo gedit ./plugins/system_management.py
That should prompt you for the root password and then open up a text editor with some python code in it. You will want to hit Ctrl-F and look for "mintInstall" (without the quotes of course) and in my case, I found the following lines of code:
Button1 = easyButton( "/usr/lib/linuxmint/mintSystem/icon.png", self.iconsize, [_("Software manager")], -1, -1 )
Button1.connect( "clicked", self.ButtonClicked, "/usr/lib/linuxmint/mintInstall/frontend.py" )
self.systemBtnHolder.pack_start( Button1, False, False )
self.mintMenuWin.setTooltip( Button1, _("Browse and install available software") )
All you want to do is comment out those lines by simply putting a # at the beginning of each line. Then simply log out and log back in and that part of the menu should be gone. Let me know if you have any problems or if nothing at all is working and I can try to assist you further.
