Your low graphics mode is because the system is stuck in recovery mode with the 'nomodeset' kernel option:
[ 0.000000] Command line: BOOT_IMAGE=/vmlinuz-4.15.0-36-generic root=/dev/mapper/ubuntu--vg-root ro recovery nomodeset To fix this, please reboot and tap Escape immediately as soon as you see the first purple screen. Now navigate the menus and find the default kernel option that is not recovery mode. When done, please confirm the correct change has been made by running: cat /proc/cmdline ** Package changed: xorg (Ubuntu) => xorg-server (Ubuntu) ** Changed in: xorg-server (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1799280 Title: Low graphics mode with ubuntu 18.04 Status in xorg-server package in Ubuntu: Incomplete Bug description: I have problem login since update to 18.04 last week.
