With F28 on my P50, I was able to detect a second display and at least mirror the contents of the P50 on it. It was never able to work as an extension to the P50 display, but I could live with that.
Upon installing F29, however, the second display cannot even be detected, so I only have the laptop display. That's not bad, unless you've spent good money to have a nice large display, and even worse if you need to give a presentation and mirror the display on another display device.
Bluetooth does not work, either. The Bluetooth device connects for a few seconds, and then disconnects. New attempts to connect to the device return, "Connection Failed: Protocol not available."
These are pretty bad failures to have on an OS desktop, so I'm somewhat surprised not to see them on the "Common F29 bugs" page.
I can't be the only one using F29 on a P50, so perhaps there are BIOS or X settings that I need to implement.
