It's with a Samsung Q35 with VGA Output. Before I used Gentoo and I didn't have any problems connecting the external monitor. In the beginning it works, just after a while it starts flashing every few minutes until finally the monitor becomes black. I can still switch to TTY1 to reboot the system (restarting gdm doesn't help, afterwards the monitor still stays black). I'm using the external monitor only, switching of the laptop monitor.
