please run 'apport-collect 1802353'
it's likely that some component is missing your GPU pci-id, but looks
like it's not the kernel since drm loads.

Title:
Ubuntu 18.04 falls back to LLVMpipe (CPU render) with Intel graphics
Status in xorg-server package in Ubuntu:
Incomplete
Bug description:
A fresh Xubuntu 18.04.1 install (from an ISO), on a machine with only the
Intel integrated graphics (i9-9900k => UHD-630). The graphic drivers module
seems to be properly loaded, but X rendering seems to fallback to LLVMpipe.
This was the case immediately after the install. The performance of the SW
rendering improved significantly after the first update with the latest
packages.

OpenGL renderer string: llvmpipe (LLVM 6.0, 256 bits)

I tried using the latest stable mesa from ubuntu-x-swat/updates but it
did not help (I ppa-purge'd it before generating the bug report)
