The settings that Xconfigurator saves for the monitor
Acerview 78ie are incorrect. First of all, there are two
copies of Acerview 78ie listed. But mainly, the settings for
modes "1152x864" and "1024x768" are wroong. They cause a
complete crash on my computer when trying to use those
modes. This monitor can support a maximum refresh rate of
85Hz at "1024x768" as opposed to the listed 100Hz, and a
maximum of ~75Hz at "1152x864" (it can do 78Hz). The setting
of 100Hz is listed for that mode also. Commenting those
modes out fixed the problem.

Thanks for your time,
Alex
