--- Comment #16 from Elmar Stellnberger estellnb@gmail.com 2011-02-23 20:45:45 --- As Comment #15 shows there is currently something more fundamentally messed up with KMS (which is apparently not EDID-related). Actually the situation has rather deteriorated instead of improving: 2.6.34-12.1 & -9.3: itg: works, ext: dark 2.6.36.1-1, Comment #1: non-deterministic, once it worked for both monitors 2.6.38-0.0.12: both monitors: vertical pixelry, nothing works (results completed by downstream report from openSuSE as linked by Comment #1.) If it works for other cards KMS does probably have a problem with ATI or just ATI Mobility 2xxx cards (I am planning to make a request to the oS core test team in this regard and will tell you as soon as results should become available.).
