Ubuntu 20.04 Boot Fail after DisplayLink Driver Installed ASUS TUF

omegatheta · 10-18-2021, 05:49 AM

What worked for me was removing nomodeset.

Context being - after removing nomodeset, I could get past the hdaudio hdaudio C0D3: unable to bind the codec error onto the login screen and could log in, but my HP laptop would shut down abruptly - which is why I had nomodeset in the first place.

My NVIDIA drivers were messy. They wouldn't function, nor would they get installed properly.

After some forum reading, it turned out that nomodeset isn't a necessity if nvidia drivers are installed properly. I installed a fresh copy of Ubuntu 20.04 LTS, booted in keeping nomodeset, apt installed nvidia-utils-470, rebooted. Now NVIDIA drivers don't boot with nomodeset. Rebooted into a root shell in recover mode, verified NVIDIA drivers are working with nvidia-smi. Removed nomodeset from grub, and rebooted.

Everything was working fine now. Could install Display Link drivers and could reboot without any errors.

I have installed the latest firmware of display link USB with version displaylink-driver-5.4.1-55.174.run and start or reboot of machine fails.

During boot there is no error and boot stop as following:

[ OK ] Started Snap Daemon. Starting Wait until snapd is fully seeded„.
[ OK ] Started Daemon for power management.
[ OK ] Finished Wait until snapd is fully seeded, Starting Load/Save Screen Backlight Brightness of becklight:intel_backlight...
[ OK ] Finished Load/Save Screen Backlight Brightness of becklight:intel_backlight. Starting Save/Restore Sound Card State...
[ OK ] Finished Save/Restore Sound Card State.
[ OK ] Reached target Sound Card.
[ OK ] Finished Network Manager Wait Online.
[ OK ] Reached target Network is Online. Starting Docker Application Container Engine...
[ OK ] Starting Tool to automatically collect and submit kernel crash signatures...
[ OK ] Started crash report submission daemon.
[ OK ] Started Tool to automatically collect and submit kernel crash signatures.
_

If i remove driver with: sudo displaylink-installer uninstall Ubuntu start correctly.

I'm not able to open a ticket because there is no error. Do you have some idea to see where could be a log to see the problem?
