I am having a really annoying bug.
I am using mint13 x86_64 with cinnamon, nvidia graphics cards using oficial nvidia drivers and a dual screen setup. When I lock my screen and inmediatly unlock it works ok but if I go away from my computer for a while and my screens go to sleep (the system don´t suspend or sleep) then when I try to login again I don´t get the password prompt but just a blue screen where I can´t do nothing . I can´t login again without restarting mdm so I lose all my current work.
It´s a really important bug for me as I can´t work this way
Is anyone else having this problem? It´s a pain because everything else in cinnamon is working great for me.
many thanks for any help.
