I have just upgraded from Fedora-21 to Fedora-22 and am now unable to
control the GUI of applications based on GTK, namely evolution and (I
think) firefox. There was a function to do this in KDE as released
under Fedora-21 (KDE-4, I think), but under Fedora-22 (KDE-5), there
doesn't seem any way to set fonts, scrollbars, window decorations, etc.
How do you do it? Pointers to web pages are very welcome.
Many Thanks - jon
