Hello I have a small issue with xgamma for a very long time that nobody could explain to me, so now I'd like to ask the developers.
To get decent colors on my workstation and external monitors I want to apply gamma correction. For me these magic values do it "Gamma 0.75 0.65 0.60", I set them in xorg.conf for each monitor. If it happens that an external monitor wasn't connected when I started X I can attach it with xrandr. Well when I do that the colors on the monitor are completely off. Even though xgamma reports "-> Red 0.750, Green 0.650, Blue 0.600" when I check, the colors are simply wrong. I have to kill X, start, and everything is back to normal. These forced restarts partly defeat the hotplugging ideas in xrandr. Here's what Xorg.0.log has to say: > [ 44816.100] (II) intel(0): Using default gamma of (1.0, 1.0, 1.0) unless > otherwise stated. > [ 44816.101] (II) intel(0): Output VGA1 wants gamma correction (0.8, 0.6, 0.6) Trying to correct colors my self, after using xrandr, isn't succesful. xgamma doesn't produce good colors. I have also tried to set gamma with xrandr, both when attaching the display or afterwords, i.e. by using this switch --gamma 0.75:0.65:0.60 or --gamma 0.8:0.6:0.6. This produces bad results as well. Colors are always wrong, always very washed out to my eye. Nothing but an X restart does it for years, across 5 portable computers and all forms and sizes of CRT and LCD monitors. Could anyone explain why? Thanks. -- Adrian C.
