The user can also specify their preference, so I reckon you likely didn't specify a preference; and what Xorg thinks you want isn't what you want. Look for the string "EDID" in both logs and make comparisons in that area. Before you do that, run "genlop -l" or examine emerge.log to find what upgrades and merges were done in the last three months that affect resolution. -- alan dot mckinnon at gmail dot com
