with last update (yesterday, March 11 2014) I had a problem with display management.
I have a macbook pro with sabayon installed (gnome + cinnamon) as a primary os for several months; I've always used a Samsung external monitor and everything has gone well.
As I said, after the last update (executed without the external monitor), after a reboot and after stopping the system with the external monitor active: now I can not see anything on mac display.
Sabayon boots regularly, but the screen of the mac is turned off. Switching on tty01, the system is on and everything is running but I can not see anything from x server.
If I connect the external monitor, the image returns (always and only on the external monitor), the picture during login is totally decentralized but I can log in using the keyboard (enter + password + enter). Once into session images are ok.
I did several tests using cinnamon-settings to execute the display manager but there is nothing to do.
Please give me some help
Thankl in advantage
