I am upgrading a freepbx distro from 13 to 14 using the upgrade tool. After the system reboots the second time I have video for awhile then the video just stops and never comes back on. After the upgrade is complete the machine functions with no video output. I can access the machine VIA SSH and the web GUI. I’ve read online I can set the video in grub to nomodeset, and that should fix the issue. Where do I put the nomodeset in grub? Can I edit the grub fia ssh into the machine or can I only get it on reboot?
I’m running this as a VM on proxmox .
