There is a monitor (vga port) and a beamer connected (HDMI) to it - both using full HD resolution.

When i use the monitor the system is running stable without problems.
But when the beamer on the HDMI port is active, the system is crashing after a while!
This can end up in a reboot loop!
Everytime the system activates the graphic mode it crashes again.
Disconnecting the HDMI the system can boot normal.

I only found this error messages in the syslog:

console-kit-daemon[1810]: console-kit-daemon[1810]: GLib-CRITICAL: Source ID 44 was not found when attempting to remove it
console-kit-daemon[1810]: GLib-CRITICAL: Source ID 44 was not found when attempting to remove it

I will try to make a copy of the running system to another parition and upgrade it to testing.
