Default Samsung SyncMaster U70

Hi,

I'm trying to get SyncMaster U70 working with Manjaro distribution, and I have managed to do so once by following Arch DisplayLink Wiki. With some messing and USB reconnect xrandr --listproviders returned 2 providers and it worked well until reboot. I couldn't make it work again since. If I try to reload the udl module, machine often hangs. I'm not sure if U70 is DL-1xxx device?

Code:
/etc/modprobe.d/blacklist.conf
blacklist udlfb
Code:
uname -r
4.10.12-1-MANJARO
Code:
lsusb
Bus 001 Device 002: ID 17e9:0103 DisplayLink
Code:
lsmod | grep udl
udl                    28672  0
drm_kms_helper        126976  2 udl,radeon
drm                   303104  9 udl,radeon,ttm,drm_kms_helper

Code:
dmesg | grep udl
