DLPX-95518 Cannot access graphics console with UEFI boot

[tonynguien]

Background

This change is the same as #344 which we inadvertently dropped when merging os-upgrade branch

The change enables CONFIG_DRM (Linux Direct Rendering Manager) kernel build option to include kernel graphic/driver framework which is necessary for graphical console on UEFI systems.

Solution

Enabling the CONFIG_DRM kernel build option.

Testing Done

• ESX and HyperV VMs have graphical console
• Graphical console works after upgrade 2025.5 VM to new version
• AWS VM upgrade works as expected, secure boot enabled after upgrade/reboot

have we looked into how I lost this during the LTS merge work?

I don't know how to look into that. And I'm not sure it's worth our effort at the moment.

I don't even see #344 in the origin/os-upgrade branch.. not sure how that got dropped from the project branch.. interesting..

Well, LTS upgrade work is something we'll have to do every couple years.. so I agree it doesn't really matter w.r.t. 2025.5.. but it would be good to understand the mistake so we can try to avoid this same mistake next time.. I'm guessing there was some manually merging or rebasing, and I forgot to git pull..

Yeah, it maybe good to document procedures and gotchas for future LTS upgrades.
