Hi,
I use Librem Mini v2 which only supports 4K monitors with DP (HDMI only works for 1080p and maybe QHD but I never had one).
I am stuck on Fedora 43 because kernel 6.18.16-200.fc43.x86_64 is the last one that inits the monitor correctly past GRUB. On newer kernels, after GRUB, the monitor goes to sleep and never wakes up even after reconnect.
On a fresh Fedora 44 test install however, after GRUB I have to physically reconnect DP cable and then it works, but I have to do it every time so I didn’t upgrade yet.
I have no other monitor to check if it works with other 4K monitors.
Checking logs on my current install is more difficult because I have LUKS encryption and can’t really see boot logs at this point and they don’t persist before decryption.
After booting on my current Fedora 43 I only found this in kernel logs:
i915 0000:00:02.0: [drm] *ERROR* Failed to probe lspcon
i915 0000:00:02.0: [drm] Registered 3 planes with drm panic
[drm] Initialized i915 1.6.0 for 0000:00:02.0 on minor 0
fbcon: i915drmfb (fb0) is primary device
fbcon: Deferring console take-over
i915 0000:00:02.0: [drm] fb0: i915drmfb frame buffer device
Upgrading to newest coreboot with this script: https://source.puri.sm/firmware/utility didn’t solve this either.
What can I do to solve the issue?
