Hi, To another bug whilst the problem existed only on experimental, I already had posted the problems regarding the XDG_SESSION_ID detection. Actually, after being merged into unstable, the nature of the problem changed:
Doing an "mkdir -p /run/user/0" "chmod 777 /run/user/0" before gdm script is run, helps so that the login window is displayed, and nothing stays blank. However, now 2 different problems occur: 1) when timed login is enabled, the input switches to the "sign in" button after each letter of the password. The problem is gone, when timed login is disabled 2) when I log myself in, I see each gnome-related process start, like gnome-shell and children, however the screen stays blank, and nothing is shown except mouse pointer; however it has my own pointer style. Maybe, someone knows a solution to make gdm log me in "correctly"? Regards, Yusuf.
