After I tried to install swift on my Debian 9 machine, Suddenly I faced a big problem (I couldn't access Debian GUI) I solved this issue by some terminal command like
sudo apt-get install gdm3 and
apt-get install firmware-misc and more.
Now I can access my GUI normally but,
- I cannot open my user account (on login screen I can insert my user name and password but I cannot login, The two text boxes become empty after I hit login) when I logged in with root I can get access to my user name via terminal.
- I cannot open Firefox browser.
- I cannot open Opera browser.
The message file on
Error reading existing Xauthority: Failed to open file “/home/amraly/.Xauthority”: Permission denied
I think that number 2 and 3 can solve by install them again but number one is my main problem.
