Bug Description
1. The login manager works but as soon as I log in, the screen is filled with colored vertical stripes and is unusable. I found that if I change the screen resolution to the maximum (1920x1080), then the screen is ok. Any other resolution that I've tried (eg (1440x900 used to be my preference) causes the unreadable display and it does not revert back, requiring a reboot.
2. Coming out of suspend, the password entry screen is displayed, but there is no response to keyboard or mouse, requiring a reboot.
