You are welcome, @Darius. Solus is pretty great, since it manages to combine the feature updates of a rolling release like Arch with the user-friendliness and stability of Ubuntu. The only real problem with it is a lack of available software at times due to this not having the community size and organisation of either Arch or Ubuntu. I get the feeling that Solus needs more maintainers for software packaging and development.

I had problems with installing Solus with the UEFI too. I also ended up not getting to the GUI, but rather being in the Linux Mint (prior OS on device) GRUB menu. The difficulty of that for me was that UEFI mode for my bios doesn't naturally show USB drive extensions, and the legacy BIOS mode doesn't work with a UEFI flash drive. Did you check the formatting of your hard drive and Live USB drive, @Darius? Both of them need to be in GPT format, and the BIOS also needs to be set to UEFI mode to read them.

Update: Same error as before still remains after package "vulkan" update to 1.2.154.1-21 version.
