We use Packer to create Windows (server 2019) AMI’s for launching on AWS g3.
We need Grid driver because our application need directx/directdraw.
Setup contains an autologon user, which does screengrabbing in 1920x1080 resolution.
This works fine on g3 instances !
But on g4dn.4xlarge i cannot get it to work, the autologin user has no 1920x1080 capabilities after reboot.
When i login with RDP, with this user, things work.
But need it to work without manual logging in after a reboot.
Tried several versions of the grid driver , and even latest gaming driver, but all seem to have this issue.
Why does this work on g3 and not on g4 ?
