The reason you don't see any Intel graphics drivers in the "Addditional Drivers" tab is that none are needed. The Intel graphics driver (i915) is open source and already included in the kernel, and from your logs it has been loaded.
There's nothing I'm seeing currently which indicates a kernel issue. My best guess as to which package decides whether or not to offer wayland sessions is gdm3, so I'll add that to the bug report. ** Also affects: gdm3 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1925750 Title: Ubuntu 21.04 not loading correctly intel graphics driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1925750/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
