Fedora 25 and Display Link
Hi Guys,
Before I attempt to update my Fedora 24 to the latest version, has anybody already figured if the displaylink drivers are still working after the upgrade? I barely was able to get it to run on FC 24 after the kernel 4.8 update and I need a stable platform before I try the upgrade. Especially since FC25 seems to now completely move over to Wayland window system. Regards Albin |

Last weekend I upgraded from fedora 24 to 25. Because Fedora 25 switched to wayland the driver broke (package is still installed though). I don't want to start debugging because I have to start working :-)
However the good news is that on the login screen you have the possibility to switch from wayland to old Xorg. With old Xorg the displaylink driver works just fine. |

Please don't assume it will just work by picking a legacy desktop environment. That was not the case for me, even though the driver appears to be loaded without error. If a DisplayLink device is crucially important to you, you may want to hold off for a few days before upgrading.
EDIT: It was working for me after changing USB ports, but now it is not. It is apparently intermittent but mostly NOT working. This could be due to my external monitor, which is an ASUS MB169B+. However, I will say it has worked reliably in the past. The only thing different is the upgrade to F25. EDIT 2: Today, on a different laptop running Fedora 25, it is working well. This is running GNOME on X11 at login. Curiously, this machine does not allow me to log in at all after selecting the default "GNOME" session (Wayland). But that is another issue. It is more important to me to have functional DisplayLink than to have Wayland. Last edited by Marlin Whitaker; 11-30-2016 at 01:26 AM. |

I upgraded last night and sadly, it's not working for me
It detects the monitors, and seems to load them just fine. I can even see the mouse when I move it on to those screens, and if I connect it while my lockscreen is up, I can even see the background for the lockscreen stuck on the monitors once I log in. However, I can't see any windows, or when I go into overview I don't see any motion. It almost seems like an issue with the config on Gnome. Needless to say, this is with switching the session to Xorg. |

Btw, I'm seeing the following in my journalctl:
evdi: [D] evdi_crtc_cursor_set:238 evdi_crtc_cursor_set unlock |

I wish I had something more useful to say, but I really didn't do anything in particular to fix it. It just started working. What driver are you using, and where did you get it? |

I've tried restarting, reinstalling the driver, and restarting the service in various combinations to no avail... still same exact problem. Even updated kernel today and that didn't help either. I also tried disabling all Gnome shell extensions in case that had something to do with it, but nothing |

The cursor lock/unlock messages are unnecessarily logged on debug level, and will be moved to verbose. Meanwhile, you can reduce the default log level for evdi...

Ahh nice. Out of curiosity I enabled level 6 logging and did not see anything strange (not that I know what most of those things mean though).
What's really strange is that the mouse moves perfectly in my screens, and now I've also see what's on my laptop screen stuck on the external monitors occasionally. |
