Unix Display
Menu path: Setup > Sessions > NoMachine NX Client > [Session Name] > Unix Display
Here, you can define the properties for image transmission from the NoMachine NX server to the NoMachine NX client.
This area is active if the parameter Setup > Sessions > NoMachine NX Client > [Session Name] > Session is set to "Unix".
- Display: Size of the display area that is used for the session
Possible values:- 640x480
- 800x600
- 1024x768
- Available area: The entire display area is used for the session. The taskbar is not visible.
- Fullscreen: The session will be shown in full-screen mode, i. e. stretched across the entire screen.
- Custom: The width and height can be freely defined.
- Multimonitor fullscreen: The session will be shown in full-screen mode on all available monitors, i.e. stretched across the entire screen of each monitor.
- Width: Width of the display area for the session (default: 800)
- Height: Height of the display area for the session (default: 600)
- Enable custom settings
☑ The image transmission properties can be changed on the client side.
☐ The image transmission properties are specified on the server side only. (default)
- Use JPEG and RGB compression: JPEG compression (results in losses) as well as RGB compression (loss-free) will be used. The level of JPEG compression will be adjusted dynamically depending on the compressibility.
- Use JPEG and RGB compression, and use custom JPEG quality: JPEG compression (results in losses) as well as RGB compression (loss-free) will be used. The level of JPEG compression is specified by the parameter JPEG quality.
- Only use JPEG compression: Only JPEG compression (results in losses) will be used. The level of JPEG compression will be adjusted dynamically depending on the compressibility.
- Use JPEG compression and custom JPEG quality: Only JPEG compression (results in losses) will be used. The level of JPEG compression is specified by the parameter JPEG quality.
- Only use RGB compression: Only RGB compression (loss-free) will be used.
- Use plain X bitmaps: The images will be transmitted as bitmaps without compression.
- JPEG quality: If Use JPEG and RGB compression and define JPEG quality or Use JPEG compression and define JPEG quality is enabled, the quality of images in JPEG format can be defined (default: 6).
- Use render extension
☑ The "Render" or "XRender" protocol extension is enabled. This allows a transparency effect where windows overlap on the screen. (default)
- Disable the backing-store
☑ The cache is disabled. This reduces the amount of memory needed. However, the speed of the session may be reduced.
☐ The cache is enabled. (default)
- Disable the composite extension
☑ The "Composite" protocol extension is disabled. Transparency effects where windows overlap on the screen are not possible.
☐ The "Composite" protocol extension is enabled. (default)
- Disable the shared memory extension
☑ The shared memory extension is disabled.
☐ The shared memory extension is enabled. (default)
- Disable emulation of shared pixmaps
☑ The emulation of shared images (shared pixmaps) is disabled.
☐ The emulation of shared images (shared pixmaps) is enabled. (default)
