January 3, 2023 at 10:26 in reply to: Can’t connect to the NoMachine server after moving to a new server #42275
please try to run this command on the server machine and tell us if it reports any error:
sudo /etc/NX/nxserver --eglcapture yes
Then restart the display manager and the NoMachine server to make changes effective:
sudo systemctl restart display-manager sudo /etc/NX/nxserver --restart
Let us know if that solves the problem.December 27, 2022 at 11:00 in reply to: Screen on client side blurs everytime I scroll #42148
Thank you for the report! It seems that what you were seeing is the expected behaviour. By default NoMachine uses progressive refinement of the image quality (what is called ‘multi-pass encoding’ in the option) in order to achieve the minimum response time. Alternatively to disabling those options, you may try to increase the display quality. This will make the progressive refinement quicker.December 9, 2022 at 13:08 in reply to: Screen on client side blurs everytime I scroll #41902
would it be possible for you to show us a video of the behaviour you are seeing? In the meanwhile, you may try these options in the session menu, Display settings, Advanced:
– Disable network-adaptive display quality
– Disable multi-pass display encodingOctober 13, 2022 at 16:38 in reply to: Dual display on Mac – 2nd monitor not showing up #40743
assuming you chose to see ALL remote monitors, you have two options to see both of them at once: in the Display panel of the session menu you can select the ‘Scale to window’ view mode, so that all remote screens will be scaled to fit the Player window area; in the same panel you can also select ‘Fullscreen on all monitors’, so that the remote screens will span across both your local screens. In a future NoMachine version we also plan to extend support for multiple monitors by allowing to show each remote monitor in a separate NoMachine Player window. Unfortunately at the moment I’m not able to say when this implementation will be completed.October 6, 2022 at 17:27 in reply to: Dual display on Mac – 2nd monitor not showing up #40639
Ok on 1 of the 2 iMacs we are using the 2nd monitor is not showing up as an option.
Do you confirm the desktop is extended on the second monitor and not mirrored? If that’s confirmed, would you send us the logs from the problematic iMac? You can do so by following the instructions in https://kb.nomachine.com/DT11R00182 and send the logs to forum[at]nomachine[dot]com.
Also the video is pixelated for a different iMac with just the built in display. Will adjusting the video options fix that?
You may try to increase Display quality and maybe disable ‘Scale to window’ mode if it’s enabled. If adjusting these settings doesn’t help, please send us a screenshot showing the problem.September 28, 2022 at 09:26 in reply to: Dual display on Mac – 2nd monitor not showing up #40410
about your first question, you should be able to see all server monitors, one at a time or all at the same time, depending on the selected option. Can you please show us a screenshot of your Display settings panel (https://kb.nomachine.com/DT06S00218?s=menu%20panel#5.8)?
As for the second question, NoMachine can’t create virtual monitors on the server. NoMachine connects to the physical display of the server and shows all the monitors physically attached there.September 26, 2022 at 14:47 in reply to: White screen after first connect since v8 #40355
would you reproduce the issue again with hardware encoding enabled and send server side logs to forum[at]nomachine[dot]com? Please find instructions in https://kb.nomachine.com/DT11R00182.September 20, 2022 at 10:44 in reply to: Session window shows small “noisy” frame instead of remote desktop #40218
can you check if that still occurs after disabling hardware decoding on the client? To do so, open the session menu panel (by pressing Ctrl+Alt+0 or by the page peel), enter Display settings, click Modify for the advanced option and check ‘Disable client side hardware decoding’.September 20, 2022 at 10:35 in reply to: Custom libavcodec parameter for NoMachine #40217
you can already set the number of cores to be used for encoding in the ‘node.cfg’ file on the server, by editing the ‘DisplayEncoderThreads’ configuration key. That said, it has to be noted that NoMachine, by default, already chooses the best number of cores for encoding, basing on the number of available cores.August 22, 2022 at 12:12 in reply to: Keypad key mapping changed with NX #39833
The .Xmodmap file is taken into consideration by the XQuartz X server on the Mac, but will be ignored on the Linux side. When you use ‘ssh -Y’, the X server the application is connected to is XQuartz on the Mac. On the contrary, when you connect via a NoMachine virtual session, the virtual X server the application connects to runs on server side. The correct way to achieve the same behaviour with a NoMachine virtual session is to run this command in a terminal inside the session:
xmodmap -e "keycode 79 = KP_F1"
(Note that normally the keycode for the NumLock key is 77 on Linux and not 79 as it is for XQuartz.)August 18, 2022 at 15:07 in reply to: Keypad key mapping changed with NX #39776
did you create the .Xmodmap file on the Mac or on the Linux machine?August 17, 2022 at 12:17 in reply to: Black screen with mouse showing upon login #39738
There seems to be some issue with the drivers. Please try to edit the $HOME/.nx/config/player.cfg file and change the ‘Enable hardware accelerated decoding’ key to:
<option key=”Enable hardware accelerated decoding” value=”disabled” />August 16, 2022 at 11:38 in reply to: Could not create a virtual desktop on RHEL 8 #39719
But changing the ‘DefaultDesktopCommand ‘ to the one suggested by you allowed the user to login but the graphics acceleration seems to be missing.
Acceleration by means of VirtualGL can be enabled either explicitly by the vglrun command (even only for specific applications) or implicitly for the whole desktop by the
'nxserver --virtualgl yes'command. That DefaultDesktopCommand was provided to you assuming you were using the second method. You can find further details in https://kb.nomachine.com/AR05P00982.
Furthermore, when I used my version of ‘DefaultDesktopCommand ‘only one of my clients with Mac could not create a NoMachine session.
Can you send the logs from this specific case?August 12, 2022 at 16:15 in reply to: Black screen with mouse showing upon login #39692
Disabling H.264 solved the issue for Liftaren. Is it the same for you?
And can you both try to check ‘Disable client side hardware decoding’ in the Display settings tab of the menu panel (Modify button)? Is this enough to solve the problem even when using H.264?
And as Britgirl mentioned, logs would be useful, especially client side logs:August 12, 2022 at 16:01 in reply to: GUI login showing up as incorrect password #39691
it’s not clear to me if you are talking about the username/password you have to enter to connect to the server, or the credentials you have to enter into the remote desktop’s login window (when you are already connected with NoMachine to the Debian machine) to get to the user’s desktop. Can you please clarify on this point?
That said, would you send us the logs? You can use instructions in https://kb.nomachine.com/DT11R00182 for the server side, and https://kb.nomachine.com/DT11R00181#2.1 for the client side. You can send them to forum[at]nomachine[dot]com by referencing this topic.
