[Bug 404421] Re: "Failed to restore crtc configuration: -22" on i915

[Jason Alan Graves]

I don't have a keyboard. I am installing this on a Samsung Q1 Ultra and
it does not have the function keys.

@Jason: from a live CD, type F6 on the boot screen to select advanced options, change the kernel cmdline to add i915.modeset=0 after "--", so if it was e.g.:
... boot=casper -- 
change it to:
... boot=casper -- i915.modeset=0

that should be preserved upon install
