I've been a big Xubuntu fan for quite a while myself. I recently put 18.04 on a VM to give it a test drive, and found that they've tweaked XFCE so that you have to be ridiculously precise at moving the mouse to a lower corner if you want to resize a window. The margin for getting a lower-corner drag cursor seems to be one pixel at best.
Argh. I've seen this problem over and over on a variety of Ubuntu versions over the years, as if they don't want me resizing windows.
Is there any way to tweak this? I'm not at all liking it. My 16.04 installations are much better in this regard.
This isn't a solution but `a just in case you are not aware` You can press alt+right click and hold then drag near the corner of the window to resize it (alt+left drag moves it).
I understand that there are times when that isn't work so it's nice to have both options. ( I wrote a browser based windowing system and have experimented with having the bezels on the windows be quite large and/or auto-expanding when the mouse nears them to make resizes as easy as possible since hard to hit pixel thing annoys me so much)
"Apparently this problem has been around for years, and one bug report has been closed "won't fix". The issue has been reopened with Bug 11808 - Xfwm: Increase the resize border of window.
The width of the grab area is controlled by the theme." 1
Most people appear to circumvent the problem by using another means of resizing windows.
"As soon as your keyboard-shortcut (in Xfce upstream its Alt+F8) is hit, you can then resize the window by either moving your mouse (no need to click or drag) or use your keyboard arrow keys." 2
The tweak I found was essentially learning a new way to resize windows. Hold ALT and right-click-drag from anywhere inside the windows at the lower right corner and it'll grab the window and resize it as you move the mouse.
I know it's not a fix, and it is still cumbersome if all you have at the moment is a laptop trackpad. But it beats having to update your destkop environment's chrome and all that jazz. I find XFCE's window chrome pleasing and minimal, the only issue is exactly that, you only have 1px of hot area at the borders.
Doesn't this depend on the theme you choose in Window Manager settings? Kokodi or Moheli might give you more pixels to grab than whatever theme you're using now.
