Hello. I've been having an issue with Fedora on my Dell Precision M4800 Laptop that my colleagues using the same hardware have not been having. This is a fresh format and install of Fedora 26 with upgrades in place. If I have a monitor plugged into the display port, each time I login it does a couple of things. 1: It logs in, but the monitor on the display port is not functional, but I can see the mouse on it. In this scenario I adjust the display settings to rotate the monitor and put it back, it will either crash back to the login page, or start working. 2: It tries to start, and cycles back to the login screen. Sometimes there are artifacts on the dell port monitor. I've had my laptop hardware swapped out for a completely different machine, and my co-workers use it with the same model to no issue. If I try over and over, I can get it to long and then start using the second monitor. It's getting frustrating as one might imagine as I try to move in and out of meetings, if I leave it in place it works fine but if I have to unplug and reconnect it's back to cycling.

How do you do this, to re-attach the second monitor? Some xrandr command? I have similar Hardware like you, and I never got my external monitor attached to my computer via minidisplay port on F26. https://bugzilla.redhat.com/show_bug.cgi?id=1470845 F24, after a little bit of tuning, worked like a charm in that regard ...

I type my password in over and over until it just finally works.
This message is a reminder that Fedora 26 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 26. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '26'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 26 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Dell's switchable graphics in the bios, once disabled cleared this issue up. Leaving crumbs in case someone else comes across this issue.
