Comment 3 for bug 1825709

Hello Mr. Daniel for your quick reply.
Unfortunately, I do not have a video recording of the issue. I have even
roll back my system to a previous back up since the issues was too
burdersome that i was not able to use my laptop correctly. That was
because, each reboot, I needed to go to tty and change the permissions (
owner) of the file .Xauthority and .ICEauthority, then recall 'startx' from
the tty. and even so the the graphic issue persist. now with the roll back
since last night things are seem fine.

Thanks for your help
