Over here you can post issues and tips regarding XFCE.
There are a couple of issues i have with the Xfce desktop. The lock screen does not function and i’m not sure why as it works in other distros that i have tried. The second thing that i’m seeing is my video now goes wonky when the desktop loads to the final background screen since updating to Xfce 4.14. It never did this before.
how lightweight is xfce compared to lxde/lxqt
