Since the latest portage update, emerge only updates the XTerm title when color output is enabled. Removing the "havecolor" test from the xtermTitle function in pym/output.py)fixes this. This behavior is a problem for me because i have problems reading the color output, but i do appreciate the XTerm titles :) Reproducible: Always Steps to Reproduce: 1. Run emerge --color y (...) and emerge --color n (...) and look at the XTerm title
Thanks, this is fixed in svn r5950.
This has been released in 2.1.2-r10.
