Comment 16 for bug 1705369

@Daniel

This is what I did:

1- Without the bug, this is the output
cat /proc/cmdline:
BOOT_IMAGE=/boot/vmlinuz-4.11.0-11-generic.efi.signed root=UUID=fa4d9534-68f3-4605-bbf7-5b5ea275471d ro quiet splash nomodeset vt.handoff=7

2- In /etc/default/grub I changed this line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
to this
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" then executed sudo update-grub.

3- I rebooted and got the same bug again.

4- I rebooted and went to the recovery mode (root), this is the output of cat /proc/cmdline:
BOOT_IMAGE=/boot/vmlinuz-4.11.0-11-generic.efi.signed root=UUID=fa4d9534-68f3-4605-bbf7-5b5ea275471d ro recovery nomodeset.

5- I changed that grub line back to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset" then executed update-grub.

6- I rebooted, and was able to access my desktop.

I do not have other graphics cards installed. I am using multiple monitors, not sure if that is relevant. I'll check if the integrated GPU is still enabled.
