It appears you are stuck in recovery mode, which prevents most graphics drivers from working properly ("nomodeset"):
[ 0.000000] Command line: BOOT_IMAGE=/vmlinuz-4.15.0-20-generic root=UUID=d2f3f98a-d42e-4ba5-8bcf-95d318ad089b ro recovery nomodeset To fix this, reboot and as soon as the screen turns purple, tap Escape once (and only once). Then choose Advanced options and select the normal (not the recovery) kernel. ** Package changed: xorg (Ubuntu) => ubuntu ** Changed in: ubuntu Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1769450 Title: proper display panel missing, second monitor mirrored To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1769450/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
