RE: USB-C dock - JaceAlvejetti - 01-24-2020

I looked at the Compatibility list and I see the one from deviantgnome, any one got more then one output, I am not expecting miracles but would love to get this to output to 3 displays, four if you count the PBP display, likely not doable but hey a guy can dream.

To add to the list (NON-USB-C) I tried an old HP display link model HSTNN-S02x, on the default Debian, It blanked the screen and I would assume crashed as even after unplugging it, attempting to get to a terminal, nothing working until a cold boot.

RE: USB-C dock - Arwen - 01-24-2020

@JaceAlvejetti, I really doubt you can get 3 external displays using the USB-C alternate mode Display Port. I think the max is 2. If a third works, it's likely a mirror of one of the other external displays. There simply is not enough bandwidth, if I understand correctly.

That said, it's possible you can get a 3rd external display working with a standard USB to video adapter, (aka non-USB-C alternate mode Display Port). I knew someone at work that did something similar with 2 x USB video adpaters. And 2 displays driven from his x64 laptop, plus the built in LCD. For a grand total of 5 displays.

If you want the highest resolution / refresh rate, with dual video, then you have to drop any external USB 3 speed devices in the dock. Basically when USB 3 is wanted on a dock, it drops the Display port lanes from 4 to 2. But, if you don't mind USB 2 speeds, (480Mbps), then you can use a USB C alternate mode Display Port dock that supports 4 lanes. I've even seen some that have a switch.

Last, even if you get 2 external displays working independantly, that's alot of video for our poor RK3399 SoC's graphic controller. This is not a high end, (and not expensive), laptop. So any graphic work will likely be slower than you would prefer.

RE: USB-C dock - JaceAlvejetti - 01-26-2020

@Arwen I appreciate the response, I knew what the pine book was when I bought it thus my dream statement,

Your five displays for the guy at work brings me back, for a short time me and a guy at work a few years back got into a who can get more screens on their desk war, I won out solely because I had a more powerful laptop, running Linux, which had dual video cards(intel integrated and Nvidia quatro), I managed to get both working simultaneously, which when docked allowed me to run 4 screens including the laptops lcd, then I started adding the displaylink "docks" I mentioned above, I got to six, where the two on the display links weren't good for anything but text, yay email, multiple office Messengers and the like having their own space but anything faster would clip horribly, I still use that laptop, it's an hp zbook, I think g2, but it's back down to only four screens.

So is there consensus on what the "best" multifunction (ethernet, power and video) USB c dock is currently?

RE: USB-C dock - Arwen - 01-26-2020

@JaceAlvejetti, It's still earlier days, so I don't see a consesnus on the best USB C dock.

It also matters exactly what is desired. I wanted at least 2 x USB 3 pass through ports. Some people are fine with USB 2 speeds on the dock. Others insist on HDMI ports, (and I wanted Display Port, since I went with a monitor with Display Ports).

So in the end, their may not be a "best" multifunction USB C dock.

My ideal one would cost too much, thus, basically pricing it's self out of mass production.

Anker USB C Adapter, Classic 3-in-1 USB-C Hub (https://www.amazon.com/dp/B07RN6RTXD/ref=cm_sw_r_other_apa_i_LlIkEbSBKG247)
- HDMI connection worked well. No configuration needed - plug and play
- USB-C power in worked fine
- USB-A did not work, solo or in combination with USB-C power in. Tried mouse and storage, neither being recognized, but both work when used in the PBP USB-A ports.

Aukey USB C ultra slim 4 USB 3.0 Ports (https://www.amazon.com/AUKEY-Adapter-MacBook-Chromebook-Pixelbook/dp/B0772TXG3H/ref=sr_1_1?crid=31I4D41BCWDPH&keywords=aukey+usb+c+hub+ultra+slim+usb+c+adapter+with+4+usb+3.0+ports&qid=1579819982&s=electronics&sprefix=aukey+usb+c+hub+ul%2Celectronics%2C379&sr=1-1)
- Nothing worked. Light came on showing it was drawing power, but no USB peripheral was recognized.

Personally I am keeping the Anker because I bought it for the HDMI and power in. The extra USB port was a bonus if it had worked.
The Aukey is going back as it makes no sense for any other device I own.

Anyway, posted for reference if it will help anyone.

Update: After applying MrFixIt's latest update both of the above hubs worked perfectly.

RE: USB-C dock - notthetup - 02-05-2020

Hi folks,

Just got my hands on the PBP. Starting to play around. I'm on the default Debian image.

I have a UGreen USB-C Dock (HDMI+VGA+ETH+SD+3xUSB3+USBC) https://www.ugreen.com/product/1324-en.html

I am able to get the Ethernet and USB3 connections no problem, but I can't seem to detect my external monitor.

Looking at dmesg I see the following when I plug in the dock.

Any ideas what could be causing this dpcd read failed?

RE: USB-C dock - wingmanjd - 02-07-2020

I have the Anker Power Expand 7-in-1 (Model A8352). I had to do a little work for Ubuntu Mate's netplan to properly configure the ethernet, but the other things worked immediately. I like the device.

2x USB3 A ports
1x HDMI port
1x SD card slot
1x microSD card slot
1x USBC power passthrough
1x Ethernet

RE: USB-C dock - Der Geist der Maschine - 02-10-2020

Do direct pinebook pro -> monitor connections work out of the box, e.g. a simple usb-c to hdmi, dvi or vga cable? Does that work with any hdmi, dvi and vga monitor?

RE: USB-C dock - xmixahlx - 02-10-2020

yes. early on i tested usb-c to hdmi and was working at tested 1080p 30fps with audio.

I'm running the default Debian install (updated) on my PBP, and I have two basic VGA 22" widescreen 1080p monitors connected via simple DP > VGA cables.

I can't verify that the ethernet or usb 3.0 works as I haven't used either of those yet, but I can say that it charges and displays on both monitors just fine. However, the two monitors act as one secondary monitor (they are mirrored) with the PBP screen as primary. Not sure at this point if it's a limitation on the PBP's ability to drive three 1080p monitors, compatibility with the dock (it is billed as Mac/Windows, but that never explicitly means it won't work with Linux), or if moving to Ubuntu-Mate will help (as seems to help with a variety of things).

Hey deviantgnome, were you ever able to get them to display independently?

For that matter, has anyone been able to get the PBP to have 2 external monitors? I need a machine at work that is able to run dual 1080p monitors....and that's about it. Most of my work is remoteing into other computers. I was thinking the PBP would be a perfect fit, good price and runs Linux natively, but I haven't been able to confirm it can drive 2 monitors.

Thanks

I wish! I've finally got back to playing with these (have a PinePhone that hasn't got as much luck as I'd like either!). Unfortunately, the situation is the same with both my PBPs (one is one of the early ones with an ISO keyboard, must not have been paying attention when ordering, and the other arrived back in December/January with an ANSI keyboard, both fully updated on stock OS).

I think I'm going to try installing Ubuntu, just to see what happens. Will let you all know what I find.
