I am trying to get my Ubuntu laptop to work with my new docking station, with passthrough of everything via just thunderbolt.
The docking station is working with everything except the external displays. I'm running into two separate issues.
- The monitor attached via HDMI to the hub is showing up in displays and is able to be enabled. When enabled my computer does function like the display is enabled but it remains blank.
- The monitor attached via DP to the hub is recognized by Ubuntu but when trying to enable it I get a "could not set configuration for crtc 64"

Originally when attaching the hub with either monitor plugged into it the entire system would black screen and freeze until it was unplugged at which point it would give me a "could not set configuration for crtc 64". After googling around I ended up updating my kernel from 5.3.0 to 5.19.17 which put me in the state I mentioned above (so I can now try to debug a bit). This did not fully install correctly so I do plan/hope on being able to revert back to my original kernel version once I figure this out.

to make sure that you have the latest version.
Since the kernel upgrade lshw
is throwing a segmentation fault
when run. Looking into how to resolve this but I can't get any info out of that command currently.
As another note I am still running Unity7 and not gnome, I don't believe this makes a difference since they both use X for the display server but thought I'd mention it in case.
I'm pretty sure that my laptop should be able to support dual monitors through its thunderbolt (looking at the external display section in the linked specs) so I am hoping this can be resolved. Any help would be super useful, please let me know if there is any additional information I can provide that would help debug this.
