[SOLVED] Problems with video on all versions and all Proxmox products.

[Vailij]

Hello, gentlemen!

Motherboard ASRock B760M Pro RS/D4, processor Intel Core i5-12400. I use built-in graphics.
I tried to install all versions of all products, but at the stage of loading the kernel for installation, I get damaged video graphics. I reread the entire forum, and tried all the recommended solutions for similar problems, it does not help. Pure Debian is installed without problems.

Thanks in advance for potential comments.

Hi,
does this also happen, when you use the second option in boot menu named Install Proxmox VE (Terminal UI)?
If the problem persists there too, than in next attempt try editing the boot menu entry first. This can be done by pressing e key.
For graphical Installer: at the end of the line starting with linux add vga=791 at the very end.
For Terminal UI: change vga=788 to vga=791
Start the edited entry by pressing Ctrl+x

You can try different modes as listed here: https://forums.debian.net/viewtopic.php?t=155182
Hopefully one will be compatible to your display.

If all else fails, install Proxmox on top of Debian, as here.

I guess you tried the Terminal install & the nomodeset.

Would be good to mention exactly what you tried.

Was what fba suggested helpful? From what you said, you need to try different VGA modes. If that doesn't work, please post screenshots of what you did exactly to get the blurry screen you showed in the picture you attached.

Hello, Gentlemen!

Thank you for your comments! You are very responsive people!

I tried to do everything you wrote, including installing proxmox on top of Debian. And it all worked.
But I wanted a clean install from ISO.
So I installed an additional video card, and the image became normal. And I was able to read what was written there, namely: "ISO not found" (with nomodeset).
Or, for a graphical installation, everything hung after starting the kernel from GRUB at the installation stage.
So I came to the conclusion that network installation from a PXE server is not available for Proxmox. I wrote the ISO to a USB flash drive and everything worked!

Thank you all again! Happy New Year!

You left out the main part of the story. Had you mentioned PXE install that probably would have helped others in trying to help you!

Anyway, glad you got it solved, maybe mark this thread as Solved. At the top of the thread, choose the Edit thread button, then from the (no prefix) dropdown choose Solved.
