Public bug reported: Ubuntu 14.04.1
What I expected to happen: To be able to log in What happened instead: Login manager crashed and I was not able to use it. Background: The affected machine is a Asus Q501LA laptop with no discrete graphics card. CPU is a i5-4200U and the on-die graphics is an Intel HD 4400. External monitor is a PB278Q connected via the HDMI port on the laptop; it's resolution is 2560 x 1440. Description of the problem: The machine recognizes the monitor, flashes black for a moment, and then displays a tiled copy of the log in screen across both monitors. Bluetooth touchpad is functional, but clicking any copy of the "gear" power management icons does nothing, and I cannot type in the password prompt. Only workarounds are hard restart, or drop to tty and restart lightdm. Misc. Additional information: Monitor is set up to the right of the laptop, with the monitor adjusted so that it's bottom edge is flush with the bottom edge of the laptop- that's mirrored in software. The monitor's vertical resolution is taller, so there's "empty space" above the top of the laptop's screen. In screenshots it's black (example attached.)
