Safe mode is meant as a means of
diagnosing a problem with your
computer or more specifically the
configuration of your computer's
Operating System. The smallest misconfiguration can cause
catastrophy- so why is it good to start the display at a higher
resolution and with a larger color
palette?
If I have a problem to fix with my display drivers (or modules), I do not want my "safe mode" to also be affected by these problems. Maybe that's just me, though.
