I have seen so many questions that ask something to effect of:
How to apply resolution that isn't available in "Display Settings"?
Almost all have not been solved. Such questions have been asked for the past 10 years.
Are these problems to do with poor levels of kernel support for monitors? Or some other reason?
Why is it that there is no way around this, apart from using
xrandr - which often result in BadName or gamma failed errors?
