ul30vt graphics problem

I have ul30vt. With 11.3 compositing didin’t work but now with 11.4 it works out off the box. Only bromlem is that display goes black after five lines after grub(no plash). If I continuously tap esc and touchpad, it doesn’t do that About 50% boots. Pictures two first lines are seen before black screen, and when (if) the black sreen disappears firs five lines are there instantly.


After my system gets to doing fast boot, Creating device nodes with udev it hangs for several minutes.

Then it starts with a repeating error message: Modprobe 102
