After following the instructions here: How to adjust display colors in elementary OS

I saved xrandr settings by making run it as a startup application. The settings I set for gamma automatically revert to default after deleting random fold(weird). Is this a bug?

EDIT: This actually happens if you set using xgamma or xrandr as startup application or set them through the terminal. You can set xgamma and xrandr through terminal and then delete any random folder and it will also cause gamma settings set through xrandr to revert back to default. But this only happens once per startup. After setting gamma again and then deleting folders won't cause gamma to revert to default.

Scenarios where gamma reverts to default:

  1. Deleting random files after initially setting gamma through either xrandr or xgamma. After that if you set the gamma through xrandr or xgamma again, it no longer reverts back to default gamma values; this only happens for the first time you delete a folder or file.

  2. Each time you set gamma through xrandr or xgamma, suspend the computer, unsuspend the computer, then log back into your desktop and your gamma will revert to default.

  • "deleting files" what are they?

  • What is sleep time? I guess this may be reason?

  • I tried with sleep time 5 and 50, deleting any random folder causes the gamma to revert to default. That's why I am trying to find another way of setting gamma persistently.

    Actually it happens regardless of whether you set xrandr as a startup application or not. I set xrandr to my preferred gamma setting through terminal and deleting folders sill causes gamma to revert to default. However this only happens once. After the first time If you set the gamma settings again and delete more folders after that it doesn't revert back.
