Hi,

I am trying to install Proxmox on a notebook that has a broken display, but I can use an external display.
The problem is that during the installation the display is extended and not duplicated.

So my external monitor only shows a blank screen, if I move the mouse to the left, click, hold and move to the right I can move the menu that is in the other screen but when I release the button it goes back.

Can I make proxmox boot the installation process with duplicated screen configuration instead of extended screen configuration?
 
Solved!

I booted into another distro and did "xrandr -q" and found out the internet display was named eDP-1

So I pressed "e" in the proxmox grub boot menu and wrote after "splash=quiet" video=eDP-1:d

It disabled the internal broken display and I was able to use the external display without it being extended.

Amazing, Carlos!

I've spent 3 hours trying to understand what was going on with this weird screen with "no border" on the left side, until moved the mouse into that invisible space and was able to grab and drag the EULA image into the main screen!

The "video=eDP-1:d" option solved the problem!

BTW: I don't have two monitors plugged in, but my motherboard has some funky video connectivity (VGA/HDMI/LVDS) that seems to stay active no matter what. Weird!

Thanks for your SOLVED update, man!
 
Hello, i am having the exact same problem but i couldn´t quite get it running as i am a bit of a noob with this. Could you please tell me how exactly i enter the proxmox grub boot menu ? And where do i put the video=<display name>:d ? Is it in a config somewhere ? Thank you for your answer, after searching for nearly an hour this seems like it.

edit: Figured it out, if video=eDP-1:d doesnt work try video=LVDS-1:d most laptops use these names.

Thank you man, you saved my day.
So everyone to get a good understanding.
If you get a blank (white) screen after pressing install Proxmox, you'll probably have the installation window on another display.
So, before hit enter for Proxmox Installation press "e" and find the line where is written "splash=quited" for me was silent not quiet.
After that set a space and write video=eDP-1:d and to save that press ctrl+x
You'll be promoted to the next step Installation wait about 5 sec and the Proxmox window installation will show.
