Yep Chris, it's specific to nvidia binary driver users. I've not had the problem when using nouveau, nor on other computers using the open source radeon drivers (or fglrx for that matter). https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/92599 (which is an issue with nvidia's DynamicTwinView feature not reporting the correct refresh rate) apparently got fixed, which is what you might be seeing in the code with forced 60Hz
Opening CCSM and typing 60 and pressing enter in the refresh rate box makes the desktop super smooth on my machine (from choppy). This is using the packaged nvidia binary driver in 14.04 (but it's been happening for many releases now). It doesn't remember the setting across reboots though. Is there some way I can check what refresh rate compiz is actually using? The field in CCSM is blank each time I start it. Does compiz have a debug mode that shows info about how it's detecting refresh rate, and how it's making its decision maybe? -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/1192028 Title: Compiz refresh rate resets to 50 Hz automatically To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1192028/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : compiz@lists.launchpad.net Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
