Hello.
I'm experiencing an issue, when dual-head seems to not work for combination of displays, where the total width or height in pixels exceeds some value.
Failing combinations:
1920x1080 + 1920x1080
1920x1080 + 1650x1050
Working combinations:
1920x1080 + 1280x1024
1650x1050 + 1280x1024
NOTE 1 : It works without problems with the binary driver.
NOTE 2 : There's quite good chance, that it has nothing to do with the total width/height since the 1280x1024 monitor is connected via DVI-I to D-SUB converter and it's a different brand with different timing.
