XBMC Freezes when I connect tv by vga in the laptop (logs inside)

Hi everyone.

I write here because im having problems with xbmc...

I have the htpc in a acer aspire one zg5 (atom n270, 1.5gb ram and 945gse chipset)
OP: Ubuntu 12.04 lts
Xbmc: eden version.

Xbmc works very fine in the laptop everytime, the problem appears when I connect a tv by the vga port, then always the laptop freezes and blocks, always same.

I add 3 logs, in them i just connect the tv by vga connection and then the laptop freezers at less than a minute:
