kaktuspalme Actually @murbert's GPU is still supported by the 515 series driver. The GTX 745, 750, and 750 TI from the 700 series didn't have their support dropped for whatever reason. And anyway they are using disk encryption and the nvidia driver isn't loaded until after the drive is unlocked (it's not built into the initrd as a consequence of how Solus distributes the initrd as part of the kernel packages) so it can't be the cause of the initial text-based output not appearing.
murbert what version of the kernel were you using before this update? I imagine 5.15.50 unless you hadn't updated in a while?
Anyway, I think I might have an idea of why this failed. Can you download this package and then run
sudo eopkg it /path/to/linux-current-5.15.61-217-1-x86_64.eopkg and then
sudo usysconf run -f after it. Let me know whether it helps or not.
Please then upload the kernel log from that boot. I want it whether the issue is still happening or if it's fixed.
