[SOLVED] Awful lag during Proxmox installation

[Alecz]

I am attempting to install Proxmox (for the 2nd time) from a Ventoy USB Flash Drive on a Dell T610 server with 24G Ram.

After select the Flash Drive at the boot menu and choose the Proxmox ISO, I get the option to choose the boot mode : Grub, Grub2, etc.

I select either of them and choose Console install (the Graphics on this server is really bad). At first it works well, but then it starts to lag, so I press a key and nothing happens, then I press it again, and it executes twice. I can bear with this for most of the menu, but it's impossible to set a root password.
When i type my (8-char) password, I see it echoed as more than 20 char. When I try to type an email, every letter I type is repeated multiple times.

I don't remember having this issue before and the only difference is that I am now installing on internal SATA instead of on a SATA via a USB3 interface, but I don't even get to start the installation.

So what could be causing this kind of lag during the install wizard?

from a Ventoy USB Flash Drive

Try another stick without Ventoy. (Ventoy is really great, but I've also had strange problems with it in the past. Not sure which version, though.)

Thanks, I briefly tried with another USB stick - same issue, didn't investigate much.

Occasionally, even with Ventoy it worked great, but it was a hit and miss, never figured out what triggered it.

I ended up just installing in Graphical mode, that works much better than I anticipated. Too bad I also need a mouse in my cramped environment
