Press Ctrl+Alt+F3 to log in to shell


enter ls -lA. If you see the line
do chown username:username
you might need to do sudo chmod a+wt /tmp
try to log in again at this point.


You can also try to uninstall and install lightdm
restart.

I hope this help

i tried
chown name:name ./Xauthority
sudo chmod a+wt /tmp

and relogined, but it still in infinite loop.

next, i tried uninstall lightdm

sudo apt-get purge lightdm

but it doesnt work.
it prints

some packages could not be installed. this may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of incoming.

....

the following packages have unmet dependencies:
libcheese-gtk23 : Depends: libclutter-gtk-1.0-0 but it is not going to be installed
Depends: libcogl15, same upper
libcheese7 : Depends:libclutter-gst-2.0-0 same upper
Depends: gstreamer1.0-clutter same upper
libclutter-1.0-0 : Depends: libcogl-pango15
Depends: libcogl15 are also not going to be installed.

E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

so i can't remove it
autoremove also doesn't work with same errors, and i tried apt-get -f install, but also has same problem.

I think graphic drivers can cause these problems.
because it outputs LOWER resolution(i think 640x480).

now, what should i do? please help me friends. :(

hanana; Hello; Welcome to the forum.

Let's look and see where the package manager reports the failure;
Post back - Between Code Tags - the outputs of terminal commands:


sudo apt update
