** Summary changed: - [nvidia-glx] unable to "set" proper screen refresh rate due to DynamicTwinView + Low OpenGL/compiz frame rate with NVIDIA driver
** Description changed: - This bug appears to be a documented "feature" of the nvidia driver, and has been for several years: + 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: http://us.download.nvidia.com/XFree86/Linux-x86/280.13/README/xconfigoptions.html (Search for: DynamicTwinView) WORKAROUND: (in /etc/X11/xorg.conf) Section "Device" Option "DynamicTwinView" "False" EndSection ORIGINAL DESCRIPTION: Binary package hint: xorg My Samsung SyncMaster 931BF does actually support 75 hz screen refresh rate, but xorg lets me choose only between 50 Hz and 54 Hz. Modification of /etc/X11/xorg.conf does not help. xorg worked ok on edgy.
