I am feeling a little brave, so I decided to try another DE instead of KDE. Right now I am playing with XFCE, it seems nice, but I can't for the life of me find the option to change the screen resolution, and also my normal mouse buttons don't work anymore, only the two left and right buttons, even though I have a total of 5 , left, right, the left and ride side buttons, and the wheel. I looked at the xinitrc, but it is completely different, since I chose XFCE, and I don't even know where to start on how to map my buttons.


I want to also try blackbox, but right now I am just trying to get the resolution and mouse working correctly, and I appreciate the help.

If you change between window managers using xwmconfig, this will replace your xinitrc for one designed for that window manager (this files can be found in /etc/X11/xinit/)
I would recommend you to copy one xinitrc from there to your home folder, like /home/youruser/.xinitrc and edit it to add the buttons again. After that when you want to change window manager just edit that file and replace the line that calls a window manager to call another.

try to edit your xorg.conf or XF86Config-4 file in /etc/X11 directory.
