[Desktop-packages] [Bug 92599] Re: Incorrect (low/stuttering) refresh rate with NVIDIA driver
Wait: why is this marked fix released? Problem exists on a fresh install of 13.04. I don't so much care about compiz not having the right refresh rate OOTB, but changing it and having that setting forgotten after a reboot is *maddening*. It shouldn't take to much to make sure two settings (detect refresh rate, manual refresh rate entry) don't erase themselves every boot, and I'd consider the problem fixed if this were the case. But having to resort to a kluudge (bash script with sleep 5 in it? Really?) isn't really... optimal. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/92599 Title: Incorrect (low/stuttering) refresh rate with NVIDIA driver Status in Compiz: Fix Released Status in Compiz Core: Fix Released Status in Ubutter: Making Ubuntu buttery smooth: Fix Released Status in “compiz” package in Ubuntu: Fix Released Status in “nvidia-graphics-drivers” package in Ubuntu: Invalid Bug description: The problem here is that incorrect information from the NVIDIA driver is tricking some software like Compiz into using an incorrect refresh rate, which makes the whole desktop look choppy.

The cause of this framerate problem is the DynamicTwinView feature of the NVIDIA graphics driver. It appears to be a documented feature of the driver, and has been for several years: --- Quote from the NVIDIA documentation --- Option DynamicTwinView boolean Enable or disable support for dynamically configuring TwinView on this X screen. When DynamicTwinView is enabled (the default), the refresh rate of a mode (reported through XF86VidMode or XRandR) does not correctly report the refresh rate, but instead is a unique number such that each MetaMode has a different value. This is to guarantee that MetaModes can be uniquely identified by XRandR. When DynamicTwinView is disabled, the refresh rate reported through XRandR will be accurate, but NV-CONTROL clients such as nvidia-settings will not be able to dynamically manipulate the X screen's MetaModes. TwinView can still be configured from the X config file when DynamicTwinView is disabled.
