Hey,

I am a beginner of Linux and stuff like that, but i have the following problem:
I am using Debian und i can not see the complete KDE-Desktop in the VM Window, so i have to scroll down to be able to see the taskbar, because KDE is "higher" then the VM window.

How can i change the resolution of Debian? Can i change it in VM or are there any kind of options in Debian? because i cant find them...

Thanks for help

Have you installed the guest additions?

well my problem is , if i click on "guest additions" nothing happened. you know i am a complete beginner, dont know anything about it

This should help Howto: Install Linux Guest Additions + Xorg config

i tried to do it but i received an error message: "user is not in the sudoers file."

hope that there is somebody who can help me

Debian does things differently.

Type su then press enter. Then your password and enter.
You should then be at # where you can run the commands.
Once at this prompt you can skip the sudo that is in the HOWto.
