I recently installed XFCE and I noticed that it doesn't use the entire screen. Instead it leaves empty spaces around and the visual margins of my desktop view are rounded. When I maximize for example Firefox the edges are not rounded anymore, but still Firefox fits in the sub-desktop space instead of the entire desktop space.
Sorry, but I can't provide a screenshot right now, but I hope you understood my problem.
Can anyone help me?
Just to clarify: the problem is that XFCE desktop doesn't fit the whole screen size, it leaves rounded margins instead.
I figured it out - it seems that my CRT monitor frequency was dynamically switched from 75h to 70h, which caused the problem. I switched back the original value and now it works fine.
