Hi, libgtk-3-dev is stated as containing the headers and libs for gtk developers. On my Debian Mint system it has made a really bad mess of the system. I guess it installed and updated all the packages and on my return to the system hitting any key would illuminate the screen for half a second. I rebooted okay but now, well Firefox is okay Thunderbird and Libre Office too, opening most other stuff, terminal, file, package manager etc open and close in half a second. What to do now? restore? Regards Ian.
