Comment 71 for bug 268434

Hey everyone.

I've recently installed KUbuntu v12.04 (KDE v4.8.4) and experienced similiar issues with the "Display and Monitor".

Here's what I've found in my testing/research. First, the "Display and Monitor" KCM can be used to generate an ~/.kde/share/config/.krandrrc file which is used to save your resolution/refresh rate settings.

The trick is, this file is NOT created when you click "Apply", you must click "Save as default" after clicking "Apply" to generate this file.

Since Xorg no longer uses an xorg.conf by default, there's really no other way for the system to persist resolution/rate changes except in the .krandrrc script (Generated by the "Save as default" button in the "Display and Monitor" KCM.)

I've read all the bug-report submissions and all the reproduction methods skip this button. They set their resolution, click "Apply" and then observe the new resolution change. They restart and then observe the old resolution... The problem, I think I've found, is we're not clicking "Save as default" after clicking "Apply"

I think a logical solution is to have the "Apply" button's handler function also call the handler function for "Save as default" which will eliminate this unexpected behavior for all new KDE users.

Thanks for your time.
