[Solved] Wrong lightDM resolution

Hello guys.

I can't figure out this bug... After an update, from a couple of months, the screen resolution of my laptop has changed and it is now wrong, to the point that i see a very stretched, greenish screen.
I changed the resolution using the XFCE settings and now it's ok after i do the login, but the wrong resolution is still present at the login and shortly before (i can distinguish the moment, during the boot phase, when the resolution changes).
The resolution is always good on the external display.
I use XFCE and lightDM.

What can i do to solve this little bug?
Thanks in advance for the help

Re: [Solved] Wrong lightDM resolution

Ok I found the mode to solve it.
Don't know why this bug happened in the first place, but inserting a xrandr command with the correct resolution into "display-setup-script" of the [Seat:*] part of /etc/lightdm/lightdm.conf solves it.
Hope this can help someone.
