It was Intel GPU driver issue. I have to upgraded to Ubuntu 14.10, because Intel has deprecated their driver for 14.04.
Upgrage to 14.10, and install their latest gpu driver, then issue disappeared.
Interesting thing is, the sudden logout happened only when I'm using Pd. Strange.
Thanks for the clew Claude!

hi list,
i have strange behavior using Pd.
When I do some patching in Pd, Ubuntu suddenly logouts, and I loss my current data.
I don't know what causes this problem.
Strange thins is, this unexpected sudden logout occurs only when I'm using Pd. Another application doesn't occur this problem.
I attached the Pd patch.
thanks, akntk ====================
