I have something happening that fits in the category of a minor annoyance, but it seems to me I should be able to fix it, but can't seem to figure out how. My graphics card is a Nvidia card, and there is an Nvidia Control Panel. It includes a section labeled Adjust Desktop Color Settings. That section includes a section titled How Color is Set. It has two options: Other Applications Control Color Settings, and Use Nvidia Settings. Because I could not seem to get a good balance of contrast and brightness in the Display portion of Settings, I tried changing that to the Use Nvidia Settings. That makes available slide bars for Brightness and Contrast. There, I was able to get the balance I was looking for. All well and good. However, something odd happens. When I boot the system, it comes up initially looking right--but while the boot is still finishing, I can see the screen get lighter, with less contrast. At that point, if I go back into the Nvidia Control Panel, the settings I chose are still indicated. However, if I switch to the Other Applications Control Color Settings, then BACK to the Use Nvidia Settings, then click the APPLY button, it puts the screen back the way I want it. It stays there until I shut down and reboot. Perhaps significantly (perhaps not), doing a Restart instead of a shutdown does NOT change the brightness and contrast--only when I do a cold boot. Anyone have any idea what is happening, or (more importantly) how to make the settings stick without having to open the Nvidia Control Panel after ever cold boot?
