Public bug reported: Binary package hint: xorg
I have two ViewSonic monitors a VA1912W (connected via a VGA cable) and a VX2260WM connected by DVI. With both monitors connected, the DVI monitor shows purple blues. I cannot adjust the colors with any tools I have tried. Notably xgamma only changes the first monitor. xdpyinfo shows one single "screen", and it appears that xgamma isn't able to program individual monitors comprising one screen. Removing the VA1912W VGA monitor and rebooting shows that normal purples are displayed. The color problem can be seen by looking at: http://www.lagom.nl/lcd-test/all_tests.php and http://www.lagom.nl/lcd-test/all_noprofile.php which have test images with and without color profile information attached. I don't have the knowledge or time to work out whether all the desktop is wrong, or just images in firefox (and other color profile aware apps). I've tried the monitor in sRGB and 6500K color modes with the second attached and no change. To repeat, xgamma definitely cannot adjust the 2nd (in my case DVI attached) monitor. I think this is a gamma problem related to a dual head set-up with different monitors. Is X capable of programming different gamma to multiple heads?
