Arch Linux

Hi, bug created from forum page - https://bbs.archlinux.org/viewtopic.php?id=248155


Hello,
I have Dell XPS 9550 laptop and eGPU AORUS GTX 1080 (for multiple 4k display usage).
After power loss external gpu can't be used again untill laptop reboot and seems laptop hang (keyboard didn't worked and any Ctrl-Alt-Fx too).
In anotherwords if I disconnect power cord from eGPU while laptop ON the X-server crushed immediately (it's OK) and after plugin power cord back to the eGPU the X-server starting again but no video at any screen connected and laptop don't respond to keyboard.

eGPU BIOS and laptop BIOS updated yesterday to the latest versions. Also I have 9560 and 9570 laptops with same behaviour.
Just for enshure that eGPU is OK I've tested this under Windows 10 and everything is fine and reboot not required to continiue eGPU usage.
