There is a strange problem with my fresh Ubuntu installation. I installed it to my laptop which also has an external display connected via hdmi cable. If I unplug the hdmi cable, after 1-2 seconds, the laptop powers off (not normal shutdown). Do you have any ideas where to search for the problem? Thanks, Mike
UPDATE:
This is the content of syslog:

It is quite long, so i wanted to make a shorter one. I deleted syslog file and created again with touch. I started a tail -f syslog and unplugged the cable again, but nothing happened.
I stopped the tail process and tried again, but the laptop didn't power off.
After reboot, the problem came back. The new syslog is empty.
UPDATE2:
I've reinstalled the whole system without external monitor. At first the installer quited, but for the second time I could install the system again. I've found a similar issue here (System does not boot up without connected to external monitor via HDMI). I also have an i7 processor, but every other hardware is different. I think I will just choose Win7 again.
UPDATE3:
I decided to use Ubuntu inside a virtual machine, because it solved my problem and a good option for me.
