Hallo zusammen,
ich habe ein HP Elite Book 840 G7 (das gleiche Problem existierte früher mit einem HP Elite Book 830 G5) mit Ubuntu 18.04. Ein Upgrade ist leider aus beruflichen Gründen (Toolchain) nicht möglich. Backports wären möglich. An diesem Notbook betreibe ich per USB-C DP Alt mode ein ThinkVision P27h-20. An dessen DP-out hängt ein aktiver DP auf HDMI Addapter von Benfei. Von dort geht es dann auf den DVI Eingang meines alten ViewSonic Monitors. Dieses Daisychain-Setup funktioniert auch im Prinzip.
Allerdings wird das letzte Glied, der ViewSonic, bei jedem Neustart nicht erkannt. "DP-2-1 disconnected". Stecke ich den zweiten Monitor jedoch ab und wieder ein (irgendwo in der Diasychain - Powercycle reicht nicht), wird er erkannt. "DP-2-1 connected 1920x1080+2560+0". Und alles ist bestens. Stecke ich jetzt den Laptop per USB-C wieder ab und wieder an, dann geht das Spiel von vorne los. Das ist aber auf Dauer kein Zustand, da ich mehrmals täglich den Laptop an- und abstecke.
Zusatzinfo: an einem zweiten HP 840 G7 (Fimren-E-Mail-Laptop) und einem Thinkpad (beides Win10) funktioniert das Setup tadellos. Ich nehme deshalb an, dass die Hardware im Prinzip richtig konfiguriert ist und es sich um ein Software/Treiberproblem handelt.
Anbei die entsprechenden Ausgaben.
Nach dem Boot, bzw. nach dem Eisntecken des USB-C Steckers:

Habt ihr eine Idee? Was ich bisher gefunden hab, waren Nvidia-Treiber-Probleme, aber das fällt bei mir weg. Ist ja ein Intel-Chip.
Besten Dank und viele Grüße
