fglrx_xgamma utility seems to ignore the display (-d) parameters and change the gammas of the actual screen ( for exemple :0.0 when the command was fglrx_xgamma -d :20.0 -gamma 1.0 ). The "screen" parameter seems to be skipped as well. I'm using xorg X11 system. Reproducible: Always Steps to Reproduce: 1. emerge ati-drivers & x11-xorg with fglrx driver 2. start two diff. displays, :0.0 & :1.0 3. start a terminal on display :0.0 and enter "fglrx_xgamma -d :1.0 -gamma 1.0" Actual Results: gammas are changed on display :0.0 instead of :1.0 Expected Results: change the gammas on display :1.0 instead of :0.0 I'm running x11-xorg.
File a new bug if this is still relevant w/ current ati-drivers.
