HDMI not detected on Buster

[JudeB]

Hello,
since I have installed Debian 10 on my hybrid laptop I have not been able to use external displays (HDMI) as they are not detected.
My laptop is GP73 Leopard 8Re ( https://www.msi.com/Laptop/GP73-Leopard ... cification).
Please find some relevant information:

I have also posted this on stack exchange in Unix/Linux a while ago but even though question as well received, no comments/answers were given (i.e https://unix.stackexchange.com/question ... ect=1&lq=1).
I have purged nvidia and bumblebee a few minutes ago and re installed the nvidia driver as recommended for my NVIDIA GPU.

I am quite desperate to get this to work,previously had Windows 10 and Ubuntu on this machine and it worked fine so there is nothing physically wrong with the HDMI port.
Willing to try any ideas you might have.

Thanks

Firmware?

Did you ever have bumblebee-nvidia and optirun working on the machine? Or the other option of Nvidia with xrandr as in the wiki?

I'm using a rather closely related MSI GP63 8RD on MX 19, which is a Debian Buster derivative. Bumblebee-nvidia works out of the box with this machine after using its Nvidia-Installer tool, but I've never tried to get its HDMI port working.

Code: Select all

$ optirun inxi -Gxx

Have you looked in the BIOS settings? Some computers have BIOS video settings that need to be set properly. I have no idea about your particular model, though.

Hi,

Thanks for your suggestion. I have just checked the BIOS settings and there is no option concerning the display settings. I don't recall seeing it but yet I have never looked specifically for it.

Does anybody with more insight on MSI knows if this is normal in the BIOS configuration ?

Anyhow thanks @sgosnell for pointing this out, there may be an issue here.

I have tried to install bumblebee-nvidia a while ago but I think I have not installed optirun. After I had no success with bumblebee the only thing from the Debian wiki I tried also with no success was https://wiki.debian.org/NvidiaGraphicsD ... stallation.

I will try your suggestions above your machine model is really similar to mine! Could you recommend documentation for these installations ?
Thank you so much for your answer!

I have trouble when I booth my laptop with with some monitors/TVs connected. They are simply not detected. However, if I connect them after the laptop boots (for example, after reaching the login screen), there are no issues. Maybe that could help?

Optirun is part of the whole bumblebee-nvidia deal after you install it per the wiki--not a separate package.

MSI gaming laptops do have a undocumented unlocked "BIOS" mode that one can enter with the correct key sequence. This has all kinds of advanced settings like you'll see on desktop motherboards, but you'll have to search the web to find the sequence--MSI has had all the instructions scrubbed out of the notebookcheck forums. Gamers use it to fool with the CPU voltage slopes to make it run faster under stress, or increase the RAM speed.

On MX Linux, I worked with another developer to have the MX Nvidia Installer recognize Optimus systems and set up bumble-nvidia automatically, but we also install virtualgl as a bridge, which may help get it working. Virtualgl is not in Debian, so you could try setting up bumblebee-nvidia as in the Debian wiki to see if that works. It's still pretty safe, since it shouldn't affect the Intel GPU which will still be providing the display, but you should still be making regular system backups anyway.

Another common error is making an xorg.conf file on a Bumblebee system, which the user tries to make use the nvidia driver, and results in a failure to start a GUI. Don't make that file at all.
