I made some more tests and disabled ppas from this thread, first mesa -> same problem, then I tried mainline kernel -> same, then I revert to original ubuntu -> same and finally removed grub option to find that the problem is still there ! The problem do not append with vesa driver ...
So I looked around at xorg bugzilla and found that the bug is reported : https://bugs.freedesktop.org/show_bug.cgi?id=60389
I am waiting for my bugzilla account to confirm the bug. I will also make a clean install of saucy to be sure that the bug is present at the beginning, If yes will maybe try 13.04 and 12.04 to see if they are also affected, but it will be in one week at least as I'm going to be very busy next week.
