Ubuntu and Mind Graphics Dock

Hello,
I have Windows 11 and Ubuntu 24 installed on Mind 2 as a dual boot system.

Everything is working great in windows and for Ubuntu, everything seems to be working with just the Mind 2.

But, if I try to use Ubuntu while plugged into the Mind Graphics dock, video and audio don’t work.

I have to plug my video cable into the Mind and use my monitors built in speakers.

I have a wireless mouse and usb hub plugged into the graphics dock and they both work.

Is there not a low res basic driver in Ubuntu that would allow the video to work to at least see the screen? I can’t even see the Grub boot loader screen unless I swap the cable from the dock to the Mind.

UPDATE: It appears Ubuntu detected and installed the recommended driver for the video card. I also tried the generic basic driver and neither one works.

With both audio and video not working via the Mind Graphics doc, could it be an issue with Ubuntu communicating with the dock it’s self?

Any assistance appreciated.

Thanks

Hello @isimmons

We checked Ubuntu 24.04 signal boot on Mind2 + Graphics and it works well.

Can you check the setting wheter the Graphics is detected?

Hi, thanks for responding. The Nvidia graphics is not detected.

Are there steps to get this working like with windows? Or should it just detect and work? I notice a difference with “windowing system” where mine is “wayland” and yours is “x11” Not sure how that is determined since I just installed fresh from the latest ISO and have done apt upgrade a couple of times since.

I have this under “additional drivers” if it helps.

Nothing special, you can try to select Ubuntu on Xorg in the bottom right corner to login X11 desktop and check again.

No difference with x11.

lsmod and lspci both indicate it is loaded and detected by the system but nvidia-smi shows “no devices were found”

This is on an encrypted drive and one AI suggestion was that this could be causing the driver not to load. I don’t know since lsmod shows nvidia. Well, it shows the following which I can’t understand other than it has the word “nvidia” all over the place.

➜  ~ lsmod | grep nvidia
nvidia_uvm           4972544  0
nvidia_drm            122880  0
nvidia_modeset       1355776  1 nvidia_drm
nvidia              54308864  2 nvidia_uvm,nvidia_modeset
video                  73728  4 xe,i915,nouveau,nvidia_modeset

I may need to start all over to see if the encryption is the problem. I used This Guide

But I found it may be much easier. Simple Guide

Any suggestions appreciated. I’ll post back if I find out it is something else.

Thanks

Hello @isimmons

You also need to install Graphics drivers:

sudo apt update
sudo apt install nvidia-driver-550-open
sync
sudo reboot

That was it. I had installed the proprietary driver before.

Installing the open driver, it took me through an extra step and explanation to enroll MOK (having to do with the encrypted disk and ensuring communication with the driver).

Only issue is I don’t see the grub boot menu. I have the same issue with a Dell thunderbolt dock I use at work for multi monitors. It won’t load until after entering the password to decrypt the disk.

My work around is to power on, wait about 3 seconds, hit enter, then wait about 5 seconds and blindly type the password and hit enter. This way I don’t have to swap cables from the Mind to the doc.

But the nvidia graphics is working now. Thanks

This maybe a common issue of Ubuntu and Windows dual system, you may find solution with google.
