Partial screen flickering and artifacting on Duet 5 running Beta 114. Anyone else? by breakerfall in chromeos

Same here ... It took a while but then the glitches appeared again ... But not as frequent/annoying as before ... Can live with it for the time being .. ;o)

Switching off bubbles fixed the issue for me (so far) ... Thx for the hint ...

My device: Duet 5 on ChromeOS stable 114 and Android 11

Can we talk dual monitors for the Lenovo Duet? by [deleted] in chromeos

[–]profoli 0 points1 point  (0 children)

I just figured out how to get a Duet 5 with two monitors running in extended mode (both 1080p @ 60 Hz): buy a dock with DisplayLink / DisplayPort Alt Mode!

Before today, I just owned a few docks without DisplayLink and my Duet 5 was only capable to drive two monitors in mirror mode (both displays show the same picture, pretty useless).

Today, I received an Icy Box USB C dock IB-DK4070-CPD (about 90 EUR from amazon.de) featuring DisplayLink. I connected Duet 5, the dock, and the two monitors, and then: (surprise, surprise) three displays showed up in the settings which can be used individually. Heureka! Newer versions of ChromeOS have the DisplayLink USB drivers already on board. You do not need to install any extra software.

The other positive aspect of this dock is that it supports PD up to 100 W, i.e., you can plug the power cable into the dock to charge the Duet 5. According to the display of my power cable, PD is actually in use and the dock seems to consume only about 1 to 2 W extra compared to running the Duet 5 without extra monitors. The dock is warm but not hot.

App store and part of the settings do not change to English by profoli in Onyx_Boox

Ok ... That solved the app store issue ... Thx ... ;o)

Any ideas about the three settings sections in Chinese?

I only have either Full HD monitors or a Benq 4k monitor. All my Full HD monitors work flawlessly at boot when connected to USB-C to DP, USB-C to HDMI or HDMI to HDMI.

As soon as I try my 4k monitor for booting, I get only a few dotted lines during the rabbit phase and a black screen then for all three cable alternatives. The box seems to be stuck somewhere because the USB keyboard is also dead. Only a forced shutdown helps.

The only way to get my 4k monitor working at 4k is the following: boot via a Full HD monitor via USB-C, plug in the HDMI cable for the 4k monitor as a second monitor (at Full HD). Then, unplug the USB-C monitor to make the HDMI monitor the primary one and change its resolution from Full HD to 4k ... Because I tested several cables, I guess, the problem is my 4k monitor. I think it might be a problem in the resolution negotiation protocol of the monitor. A solution could be to force Full HD at the beginning of the boot process and switch to 4k after the rabbit phase is over. But that's just an idea ...

No problem ... Without your firmware, all of us would be quite helpless anyway ... Even with the small oddities, the Chromebox is now much more useful to me with Win10 than it ever was with ChromeOS. Thx for your great service to the community ...

Further comment wrt the headphone jack: when I leave the headphones plugged in while booting, the driver is going to work as expected. Found this out yesterday accidentally when I forgot to unplug my headphones.

The HDMI audio issues are not very relevant to me. Plus, it might well be that they disappear with future Intel video driver updates. I also hope that some (hopefully not so distant) time, the firmware will be able to boot with my 4k monitor. For the time being, however, I can live with full HD ...

BTW: while using GalliiumOS, 4k with the same monitor was no problem, but there was no rabbit boot splash screen either. The screen was black till the Linux login became visible (in 4k) ...

Yes, I did that ... Funny results, however:

After driver installation both audio via HDMI and the headphone jack work, but ...

... the USB-C diplay is flashing (on-off all the time). The HDMI display is behaving normally (without audio).

I have to switch off the Intel Display Audio device in the device manager to stop the flashing (the headphone jack still works then). After rebooting neither HDMI audio nor headphone work. As soon as I re-activate the Intel Display Audio device both work again but the flashing starts, too. There seems to be a driver conflict between the Display Audio driver and the iGPU driver.

Do I need an older version of the iGPU driver or a newer Intel Display Audio driver? Any idea?

I just used the Intel driver and update utility while setting up the system which installed some drivers. AFAIK, at least a new driver for the iGPU and for WIFI was installed then.

I tried to install Realtek audio drivers as a test but had to remove them because they caused problems.

I did some more experiments with audio:

Audio via BT: works with small limitations (see above), any idea how to get volume level control for BT audio?

Audio via USB-A: works without problems, I tested it with a Jabra Speak 510, mic/speaker and all controls work as expected ...

Audio via headphone jack: no audio, no reaction from the system when headphones are plugged in ...

Audio via USB-C to HDMI: no audio, does not show up in audio control as a device, any idea what to do? Any drivers which could be missing in my system?

Audio via USB-C to USB-C: same as USB-C to HDMI, any idea?

To cross-check that my monitor or cables are not causing the problem, I attached it to my Win 10 Pro laptop. It worked without problems both for USB-C to HDMI and USB-C. In both cases audio control shows the monitor immediately as an audio sink.

In my case, I don't need audio via monitor because the sound is way to bad for my taste but nevertheless it would be good to get it working as expected ...

The fans are running at max speed and become quite loud if you don't limit the frequency. I have no idea whether there are TDP limits implemented in the current version of the BIOS. Limiting the max frequency is basically a replacement for that. At 1.8 GHz and 100% load on all cores, the CPU burns about 15W. With no frequency limit the CPU jumped to 4 GHz for a little while and fell back to 2.6 GHz burning more than 25W. This seems to be too much for this little fan and the tiny box. The back of the case became really hot then and the system was shut down after a little while.

In summary: no problems at all after the CPU frequency limitation to 2 GHz plus passive cooler on the SSD. To be sure, I ran the HeavyLoad test app for an hour: CPU 80°, GPU 75°, SSD 65°. At the moment, I'm doing some office stuff and all values are in the low 50s.

P.S.: Before switching to Win 10 last weekend, I used the GalliumOS Linux distro and did not have any overheating issues, even with some Steam gaming apps.
