How do I increase the terminal border size in xfce?
Solution 1:
Alternatively, use <Alt+Left Click> to move windows and <Alt+Right Click> to resize windows, which doesn't require that you click on the edge at all.
Solution 2:
Some of the other themes provide a border that is easier to grab. For example, I use Daloa on one of my Xfce systems. So unless you really need Greybird for some reason, I recommend trying a few of the window manager themes to find one you like.
