Ja, bedankt, ik had het net gevonden.
1. open a console window and at the prompt type the following to change the file permissions and hit enter
chmod 644 ~/.dmrc
2. type the following command to change the ownership of the file and hit enter
sudo chown your_login_name /home/your_login_name/.dmrc
3. The final step is to assign permissions on the home directory such that it is accessible only to you ( this step is very important)
sudo chmod 700 /home/your_login_name
Hoe ontstaat zoiets nu zomaar?
