It appears your system is stuck in recovery mode:
[ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-4.18.0-11-generic
root=UUID=2a4451ed-b3fe-405b-8626-01fa361e7b98 ro recovery nomodeset
To fix that, please reboot and tap Esc as soon as you see the purple
screen appear. Now choose a normal (non-recovery) kernel option in the
menus to boot.
When done, let us know if the problem is fixed and if not then run:
dmesg > newdmesg.txt
and attach newdmesg.txt here.
