I have an H-P laptop Pavilion DV4, and an external monitor Samsung SynchMaster 2253LW, connected to the HDMI port of the computer. The graphics is nVidia GeForce 9200M GS.
Strange is, that when I run the live DVD it works perfect, and I can run any of the screens, the laptop internal or the external, or both of them, and with individual resolution. The settings via the program "Monitors" is working perfect. But after installation of Mint LMDE 2 64 bit only the internal screen is showing anything.
After looking around on different forums on the internet, and when checking my system, I notice that the file /etc/X11/xorg.conf is lacking. However I have also seen on the forums, that it is normally not needed. However after a hint from someone I let create a new one:

Running xrandr without parameters is giving this:

Finally, after restarting X11 (via ctrl+alt+<baackspace>) I get this output from dmesg:
Code: Select all

Sorry for being so spacious because of all the printouts. However I wanted to be as complete as possible when asking.
