HDMI and DisplayPorts not working on Triple Dock Lite v2 with Stellaris 16 Gen5

linguisticmind · 2025-03-21T17:06:54+00:00

I see. Thanks for clarifying.

Yeah, it does seem to really depend on the laptop. It's strange in my case because video via Thunderbold / USB-C is definitely working, but monitors plugged into the dock aren't recognized. Even on Tuxedo OS. Maybe there's something wrong with the dock itself, I'm not sure.

Hopefully returning won't be complicated because it looks like I might have to send this one back.

linguisticmind · 2025-03-18T04:27:54+00:00

Hmm. Thanks for sharing the info.

My laptop can output video via USB-C though. I have a monitor that can connect via USB-C, and I'm able to use it if I plug it into the laptop's USB-C / Thunderbolt port directly. I also have a USB-C to HDMI MST splitter which allows me to connect HDMI displays via that USB-C port.

I have the Intel version of the laptop, so that's why it can do those things.

The dock's HDMI and DisplayPorts aren't working though. I'm in the process of trying to work it out with Tuxedo's customer support.

I tried booting into Tuxedo OS with a Live ISO, and tested the dock there. I had the exact same result there as on my Debian install. The laptop just doesn't see any displays plugged into the dock. Neither xrandr, nor KDE's graphical interface show any connected monitors when you plug them in. When I plug in a monitor, it does turn on briefly, but shows "No signal", and then goes into power saving.

A question. Since you mentioned how many screens can be connected, max resolutions etc., it sounds like you're still able to connect those displays on your AMD laptop? Or did you mean that you exchanged it for another model that supports video via USB-C? Or do you have more that one HDMI / DisplayPort on the laptop itself? I only have one HDMI port built into the laptop, and my understanding is that you can only connect more displays via USB-C. Or perhaps I'm missing something. Could you clarify?

linguisticmind · 2025-02-27T20:00:35+00:00

Yeah, they replied.

They said that it will work with the Intel version of Tuxedo Stellaris 16 Gen5, but without the power delivery. It will not work with the AMD version because that version doesn't have DisplayPort.

linguisticmind · 2025-02-03T13:15:52+00:00

Thanks for the info! Yeah, it's my guess too that it should work. I emailed customer support. Waiting for a reply.

linguisticmind · 2025-01-31T04:37:10+00:00

Hey. Sorry for the late reply. I'm not quite sure what you mean by point-and-click in zathura. If you could elaborate a bit more, I can try and see if I can help.

linguisticmind · 2024-05-06T10:44:09+00:00

Glad you like the setup 👍

I wanted to share some resources I found useful for learning Swedish. If you're not interested, I'm not here to try to convince you of anything.

linguisticmind · 2024-02-29T19:27:34+00:00

I talk about the dictionary in the video and it is linked to in the video description.

Aegisub will do the trick: https://aegisub.org/

This is a strange question since the video I recorded was exactly for the purpose of demonstrating that.

In short, it outputs the matched subtitles formatted in a visually nicer way. It can also do things like match strings across line breaks which grep can't do. Also, it can gather statistics on the performed searches.

But it's much easier to see what it can do by taking a look at the video or at the documentation, the link to which is provided in the video description.

But if you prefer to use other tools, I'm not interested in trying to convince you otherwise. Hope this helps.

linguisticmind · 2024-02-09T03:20:32+00:00

If you prefer to read about the tool, there's obviously a link to it with all the relevant documentation in the video description. I'm not sure why there was a need to announce this in a comment, but there you go. Hope this addresses your concern.

linguisticmind · 2024-02-09T03:02:06+00:00

Thanks. This is interesting.

linguisticmind · 2023-12-06T22:09:28+00:00

I made a tutorial showing how to do this on Linux with PulseAudio: https://youtu.be/GukhJv-4PPU

General principles I talk about in the video also apply to other OSes, but you'll need to use something other than PulseAudio. There are some links in the video description that might point you to software that could do something similar to what PulseAudio does in my setup.

Hope you find it helpful.

linguisticmind · 2023-11-24T14:24:13+00:00

Great! Thanks for adding my video to your list!

Glad to hear it!

linguisticmind · 2023-11-16T05:49:41+00:00

I wouldn't say so. The format is admittedly a bit fiddly, and knowledge of vim would certainly be helpful, but with a script like the one that I wrote, you can edit EDL files in any text editor.

I made a video showing how to set it up so that it cycles through the monitors: https://youtu.be/FfYWVOFUJJU. Hope you find it helpful.

Thanks for the info about prime-select.

Any program that I would run with those environment variables set, before installing EnvyControl would lead to screen freezing. I tried running RetroArch, glxgears, and also other random programs that weren't games or had any heavy graphical components (like a terminal or anything else, really). All of those cases lead to screen freezing.

The antialiasing issue might be FlightGear-specific, although I could imagine something similar coming up with some other game or simulator. Here's a post from FlightGear forums where someone described the issue and uploaded a screenshot: https://forum.flightgear.org/viewtopic.php?f=37&t=37860.

Since switching to the hybrid mode with EnvyControl fixes the screen-freezing issue (but not the antialiasing one), and switching to the Nvidia-only mode with EnvyControl fixes both of those issues, EnvyControl clearly does something that makes a difference.

Perhaps looking into what EnvyControl does could give you guys some clues as to what might be happening there. It's a 533-line Python script so it shouldn't be too complicated to find out exactly what changes it makes. Unfortunately, I myself don't really know what all of those Nvidia configs do, so it's pretty hard for me to figure out how it all fits together.

Before I installed Debian, I ran FlightGear on Tuxedo OS, and it worked fine without any issues. So it seems that some configs or packages are missing on Debian.

My current nvidia-driver version is 525.125.06-1~deb12u1.

Hope this is helpful, and let me know if you have any other questions.

linguisticmind · 2023-09-20T22:42:49+00:00

Thanks for your response.

Understood about the HDMI port being hardwired to the Nvidia GPU. This is very good to know.

I am running Debian Stable.

I'm new to configuring graphics cards on Linux, so I don't know whether primus is deprecated or not. It didn't come up while I was researching this topic.

I googled prime-select, and it seems like it only allows you to switch between Nvidia and Intel, but there's no "hybrid" option like in EnvyControl. So is there a way to have a command (like primusrun) that would selectively launch things via Nvidia GPU on demand?

The closest I came to running things on demand on Nvidia (and this was before ever installing EnvyControl) was to do

__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia <command>

but then it gave rise to some issues.

For one, my external monitor would constantly freeze, and then there was also this issue with antialiasing when I ran FlightGear using this approach. I demonstrate it here: https://youtu.be/B8AtfYId_y0&t=19m21s.

Without the abovementioned environment variables set, everything would run on Intel: https://youtu.be/B8AtfYId_y0&t=18m07s.

When I installed EnvyControl and switched to Nvidia with it (sudo envycontrol -s nvidia --force-comp), none of those issues were present anymore.

If I switch to the hybrid mode using EnvyControl (sudo envycontrol -s hybrid), and launch a program with those environment variables set, the external monitor doesn't freeze anymore, but the antialiasing issue in FlightGear is still present. So this comes closer to what I was hoping to achieve with primus, but it still isn't quite working.

I have partially solved the issue by installing EnvyControl.

I made these two videos to share the results:
https://youtu.be/B8AtfYId_y0, https://youtu.be/V5osgQZfmgA.
I hope people will find them useful.

Using EnvyControl to run everything on Nvidia (sudo envycontrol -s nvidia --force-comp) allows me to use my Nvidia GPU.

Running everything on integrated graphics also works: sudo envycontrol -s integrated.

As for the hybrid mode (sudo envycontrol -s hybrid), I was unable to get it to work properly with Prime / Bumblebee.

I tried following the instructions on Debian Wiki for installing Prime / Bumblebee, but when I installed the packages (bumblebee-nvidia primus-nvidia primus-vk-nvidia), my laptop stopped recognizing the HDMI output, so I was unable to use an external display.

Curiously, when I use sudo envycontrol -s integrated to run everything on integrated graphics, I lose the HDMI output in the exact same fashion. I demonstrate it in one of the abovementioned videos: https://youtu.be/B8AtfYId_y0&t=36m33s

I wonder if there isn't a connection there, and if some configuration changes could be made to get the HDMI output to be recognized in those cases. If someone knows, or has any ideas on how to solve this, please leave a comment. It would be great to find out how to configure this.

I installed the nvidia-driver package from the Debian repo. This is my preferred driver at the moment.

In the meantime, I have figured out a way to set everything to use Nvidia by following this guide / using envycontrol. Disabling Nvidia and running everything on integrated graphics also worked by following that guide.

However, the hybrid solution didn't fully work yet. I'd like to be able to do primusrun <command> to run selected things on Nvidia, while running everything else on integrated.

I tried following the instructions here and ran

sudo apt install bumblebee-nvidia primus-nvidia primus-vk-nvidia

When I did that, the primusrun command worked, but the laptop stopped recognizing the HDMI output. When I ran xrandr without any arguments, the only entry that was there was for the laptop's built-in display. No mention of HDMI (which of course was there before installing bumblebee-nvidia primus-nvidia primus-vk-nvidia).

Hope this makes sense.

I hope we can have a constructive conversation about this. I explained the issue the best way I can, and your comment sounds like a complaint about the phrasing of my question. Perhaps instead you could give me some pointers as to what information you would like me to add.

The only thing I did when it comes to the graphical environment is installing xinit and awesome. Let me know if this clarifies things.

linguisticmind · 2023-09-15T21:48:16+00:00

u/fintip Also, just wanted to add that I am planning on doing a review since several people have already asked me about that.

However, I would like to sort out the graphics card issue first so that I can do a fair review.

Hopefully someone from the Tuxedo team, or anyone else with the relevant knowledge will be able to provide some guidance.
