Notebook won't boot anymore after executing ./displaylink-debian.sh #908

Closed ReneNyffenegger closed 2 months ago

ReneNyffenegger commented 3 months ago

When using wget to download displaylink-debian.sh and executing this script, I get an error message about a missing patch file (see https://github.com/AdnanHodzic/displaylink-debian/issues/907). I don't encounter this error when cloning the github repository and executing the script in the repository. However, with this approach, the notebook won't boot anymore. So, is there a possibility to revert the changes of the script?

After removing /etc/X11/xorg.conf.d/20-displaylink.conf in recovery mode, the notebook does boot again. Of course, I am not sure if the install script messed up other parts of the OS as well.

If you run the script it asks you, if you want to install or uninstall the driver. This way you can revert the changes.

I'm having the exact same problem. After installing and rebooting, the computer get a black screen.

My laptop has hybrid graphics, with a integrated Radeon GPU and a dedicated NVIDIA GTX 1650, not sure if this is the problem.

It looks like it is working, although I haven't tested yet. I'm getting this message DisplayLink service status: up and running

Here is the output of my --debug command:

Okay, I've managed to make it boot (kudos to chat GPT). I've changed the conf file to

  1. List my radeon device instead of an intel one
  2. Select the radeon as the device for screen 0

    Identifier "layout"
    Screen 0 "radeon"
    Inactive "nvidia"

What I don't understand is what difference this conf file is supposed to make. Looks like it is pretty much the same configuration as the system default. No evdi errors are being shown on dmesg anymore, though.

Tomorrow I'll test it against a DELL UD22 dock and a WAVLINK ‎WL-UG3501HPDX adapter.

Okay, I've tested the adapters that I've mentioned earlier

The funny part is that if I connect the WAVLINK into the dock, it works

It's a known displaylink bug, but unrelated to this project. You'll have to take it up with them.
