Comment 86 for bug 589485

Thanks for the info! However, let me recall that the bug is not against unity and gnome, but xorg. For many reasons one may have X starting without unity or gnome (because of using another desktop or a transient misconfiguration). In this case, X should be able to provide readable chars even if one is on a hi-dpi monitor. X setting the DPI at 96 prevents this. Please, even if gnome and unity fix the HiDPI issue, let still have a configuration option for X allowing one to switch between:
1) Ignore the EDID and fix the dpi to 96 (current behavior, good for older hardware)
2) Respect the EDID info about dpi (good for newer hardware, but risky for projectors and TVs)
3) Respect the EDID info, with same safety checks (e.g. force some default if EDID data looks too small or too large to be credible)
