Steps to reproduce the problem here easily, on Kubuntu 13.10: * Connect a second monitor, adjust the resolutions, extend your desktop (to the right e.g.). * Open Youtube or any Video in the browser, start the video, click the fullscreen button - now you can watch the video on one of the two monitors fullscreen, the other one shows still the desktop. * now press the AudioVolumeUp button on your laptop -> what happens: plasma? randr? crashes? - all applications continue, even the video, after a short delay, and both monitors have changed to the "clone" mode, showing both 1024x768px (which none of my monitors has a native resolution). How can I provide more info?
Oh, additional info: this only happens under the proprietary nvidia driver, under nouveau everything is ok. I think this is an invalid bug then?
assume you are using ksceen in ubuntu 13.10
Yes, kscreen, von Kubuntu 13.04 and now 13.10. Probl m occurs under Intel driver as well, but less frequently.
Please attach gdb to any of the processes that crashes, reproduce the crash and upload a backtrace. This is most probably not a KScreen issue.
This is a problem in the driver, KScreen has nothing to do with sound and we don't have the "power" to break all your app's. So closing this bug as resolved/upstream.
