Once the process completes, you will be able to use Modelines with a pixel clock above 300MHz.
VIRTUAL DESKTOP FRAME RATE INSTALL
To install it, you will need to compile it on the computer running VNC Server using the below commands: sudo apt install git # Ubuntu To use resolutions like this, you will need to install the RealVNC dummy driver, which is published here: (I would try anything at this point to get an extra frame or two ) I was surprised with the results however, and I’m not sure what to think. The pixel clock is 712.34 and will not be available to select in the Virtual Mode session. Hi, This evening I was reading various forum posts both old and new, talking about both vsync on vs off as well as setting the desktop resolution/hz to certain lower values to improve msfs performance.
VIRTUAL DESKTOP FRAME RATE DRIVER
There is a known issue when using the standard dummy driver that prevents resolutions with a pixel clocker greater than 300MHz from being available. A connected user should use the standard Screen Display or Monitor app instead. Note the VNC Server RandR parameter cannot be used to enable a connected VNC Viewer user to cycle between available screen resolutions in this environment. Refer to the nf man page for more information. Replace these values as required.įor larger resolutions, you may also need to increase the VideoRam entry in the Device section. Where 1920 is the width, 1080 is the height, and 60 is the refresh rate. In versions of VNC Server earlier than 6.7.0, the file is /etc/X11/nfĪ convenient way to generate the required Modeline is by using the gtf command, e.g. You can set non-standard screen resolutions by adding additional ModeLine entries to the Monitor section of the /etc/X11/nf file. For users running SystemXorg (vncserver-x11 -virtual) Standard dummy driver For example, specifying the resolutions 1024x768,1280x1024,800圆00 allows a connected VNC Viewer user to choose the one they want dynamically by running the command xrandr –s. If you set multiple comma-separated screen resolutions, a connected VNC Viewer user can cycle between them. You can specify one or more screen resolutions (geometries) for a virtual desktop using the VNC Server RandR parameter. However, from VNC Connect 6.2.0 you can configure VNC Server to utilise the latest version of the Xorg server on your system instead, which may give a considerably better experience for Red Hat and CentOS systems. By default under Linux, VNC Server in Virtual Mode uses an old version of the Xorg server built into Xvnc, which is still recommended for Ubuntu and SUSE systems providing you change the desktop environment. It depends upon the version of the Xorg server in use.
