Ubuntu: Black screen - random log out [closed]


I've installed Ubuntu 17.10 on my new Dell XPS 13 (a machine dedicated for Linux) and I already experience some kind of trouble. Let me describe the situation: I'm working, suspending the computer by closing the lid, continue working etc. The bug I'm experiencing occurs several times a day and somehow seems to be related to ALT + TAB, especially when switching to the pdf reader but only every third time or so. Ubuntu shows a black screen with one row of @@@@@@ and logs me out. I can then log in without any trouble but all my applications are of course closed. Does anyone know a solution?


It seems like the newest system update for XPS 13 fixed the problem. I haven't experienced it yet after updating.
