I have to login into my machine 2 or 3 times when the machine went to sleep mode, after installing/removing the unity desktop
I thought it could be due to lightdm acting weird, but removing lightdm and installing different display manager (lxde, slim, cdm) wouldn't fix this problem
The first lock screen looks like the default ubuntu mate, but the second looks more like gnome(?) (see pic) even though I had gdm installed, but it didn't work at all so I removed it completely.
I really appreciate any help that be can provided.
