第一種解決思路

第二種解決思路

Launch a tty terminal by pressing ctrl + alt + f1. Once in that terminal, run the following set of commands in the same order as listed here:

sudo rm -rf ~/.cache/compizconfig-1
sudo rm -rf ~/.compiz
sudo rm -rf ~/.Xauthority
sudo dconf reset -f /org/compiz/
setsid unity
sudo reboot

If the first solution didn’t work, then this one should definitely work. In case you used a different solution to resolve such an issue, share that with us in comments below.linu
