I think this is probably a duplicate of bug 1727356. Can you please try the workaround from that bug?

Looking at this again, it appears the low resolution is caused by the kernel option 'nomodeset':

[ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-4.15.0-34-generic root=UUID=cff0943b-896f-4480-a885-69bef7b3e8cd ro quiet splash nomodeset vt.handoff=1

You need to remove 'nomodeset' from your kernel command line. You will likely then need the fix or workaround for bug 1727356 too.
