After some investigating, I have found that if I log out, switch to TTY then run startx, I get the same issue. However I noticed that if I run sudo startx, Vulkan works, and it still works after logging out and running startx as a normal user, until the computer is rebooted. Then I tried logging in as root from GDM and I got the same result. Something is probably not being initialized properly when logging in as a non-root user. I think the affected package is actually xinit, but I'm not sure.
