Recent Xorg interrogates the hardware to find what resolutions it supports and |
29 |
can pick one of those to use. The user can also specify their preference, so I |
30 |
reckon you likely didn't specify a preference; and what Xorg thinks you want |
31 |
isn't what you want. |

Look for the string "EDID" in both logs and make comparisons in that area. |
34 |
|
35 |
Before you do that, run "genlop -l" or examine emerge.log to find what |
36 |
upgrades and merges were done in the last three months that affect resolution. |
