The setup involves a custom KVM indeed, I'll attach the EDID file involved in this setup.
I tested everything as requested, no luck unfortunately. The working configuration, which I've now replicated, is involving the OEM image for Ubuntu 20.04 with which the device has been certified. Please find attached every collected dmesg and the EDID file. ** Attachment added: "dell_optiplex_tests.zip" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2036742/+attachment/5703561/+files/dell_optiplex_tests.zip -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2036742 Title: amdgpu crash on Mantic Status in linux package in Ubuntu: Confirmed Bug description: [Impact] Booting from USB the latest Mantic Desktop daily image (2023-09-20), just after the initial logs, nothing is displayed on screen.
