Comment 38 for bug 1766137

Not on first login but on switch user after entering correct password I get purple screen and mouse.

Sometimes after a long delay I can get back to the login screen. I can usually force it back to the login screen by hitting a few random cycles of ctl+alt + F1, ctl+alt F2 and ctl+alt + F3.

At this point, if I click on the the user that failed it shows a message about authorization problem (but the password was correct). At login of this user it then allows access.

I know on subsequent logins it is going to fail as soon as I see the purple screen. If I see initial black, I know it is going to work OK.

I noticed this issue on an initial clean build on erased disks. Concerned about my hardware, I rebuilt again from clean and the problem is the same. I do not have a graphics card. I have: Intel® Core™ i7-4790 CPU @ 3.60GHz × 8. Ram = 24g.
