Unsupported video frequency while installation of PVE 7.2

[TimRyan]

The "unsupported video" issues with ProxMox 7-2 iso installation. Two observations, This problem arrived with the release of the 7-2 VE iso and my workaround is to use the 7-1 iso for installation and then upgrade after the additional machine has been added to the cluster. The second observation is that this problem was observed with the initial Ubuntu 22.04. LiveServer LTS iso release, and was resolved in the subsequent 22.04.1 LTS iso and has not been seen since on Ubuntu installed to identical hardware.

My assumption is that this is a Bug and should be reported to the ProxMox maintainers as such. My guess is it would be one that started life in the Debian kernel code and just needs to be resolved in the subsequent applications of the kernel code.

My hardware is all Dell R610 and R710 rack servers and this issue is repeatable with both VGA monitors direct attached to the VGA port and in applications using a KVM switch between.

PVE uses the Ubuntu kernel, so their fix is probably already present in current PVE and we just need an iso with current packages.

What is the very latest PVE iso ? I ran into this problem when I added a new node to an existing cluster with what i thought was the very latest iso that was proxmox-ve_7.2-1.iso the iso I used earlier to build the rest of the cluster was proxmox-ve_7.1-2.iso. My workaround was to go back to the earlier iso when I added server 5 to the cluster and I am still trying to debug it

The one you stated. Unfortunately, there are no regular new iso files, so we probably have to wait until 7.3

This is not a show stopper as the 7.1 VE iso release is still available and is an easy upgrade after installation. The patching process is a bit of a chore but if you are aware of the issue its no biggie. I am very impressed with the way that the ProxMox VE 7.x system identifies the capabilities from the Dell hardware UEFI and assigns the requisite drivers virtually unassisted.

This is now an issue because 7.1 is no longer available to download as an ISO -- only 7.3, 7.2, and 6.4.

Can we at least please keep the 7.1 ISO until a better solution is available ?

For anyone that finds this thread having similar issues, using latest ISO releases with "Console Mode - nomodeset" works perfectly.
tried with proxmox-ve_8.0-2.iso
