KGamma is a tool for monitor calibration. With proper gamma settings your display will look the same on your monitor as on other monitors. You may need to correct the brightness and contrast settings of your monitor for good results. The test images helps you to find proper settings. You can store the gamma settings to the users config file or to XF86Config (root acces required for that). This are system settings, please do not use KGgamma to work on your image files. ----------------------------------------------------------------------------- Important: If you have an existing kgamma-0.11 installation, uninstall it first. The new version will not completly overwrite the old one. If you installed from source, run "make uninstall" in kgamma-0.11 base directory, or remove it manually: rm -f $KDEDIR/bin/kgamma rm -f $KDEDIR/share/autostart/kgamma_restore.desktop rm -f $KDEDIR/share/applnk/System/kgamma.desktop If you update from an existing 0.9 or 0.9.1 version, uninstall it first, or you will have an orphaned KGamma entry in KControl section "System". If you are not able to uninstall the old version, remove some files manually: rm -f $KDEDIR/share/applnk/Settings/System/kgamma.desktop rm -f $KDEDIR/share/icons/hicolor/16x16/apps/kgamma_admin.png rm -f $KDEDIR/share/icons/hicolor/32x32/apps/kgamma_admin.png rm -f $KDEDIR/share/icons/hicolor/48x48/apps/kgamma_admin.png rm -f $KDEDIR/share/icons/hicolor/16x16/apps/kgamma_user.png rm -f $KDEDIR/share/icons/hicolor/32x32/apps/kgamma_user.png rm -f $KDEDIR/share/icons/hicolor/48x48/apps/kgamma_user.png If you update from version 0.9.2, you will loose your user settings, because of format changes of kgammarc. There are known problems to compile KGamma on KDE 3.1 CVS HEAD, because of changes in DocBook format. In this case, disable documentation from Makefile. ----------------------------------------------------------------------------- After install you find KGamma in KDE Control Center, section "Look & Feel".
