I installed Loki over an older installation (prior version of Elementary) where I only saved my home partition (everything else was wiped clean). What is the best way to reset the desktop so it is back to the default? I tried copying in the files from /etc/skel, but that didn't seem to work (menu sort of appeared but standard apps in the launch bar did not).
Do you want to reset only desktop settings or all programs settings?(including desktop)
If you want to reset all settings run this command and reboot:
sudo rm -rf .*
Be sure to run this in your home directory
If you want to reset only desktop you should delete only some of this files, but i do not know which, you should wait a reply from a developer.
