The following packages have unmet dependencies: The following information may help to resolve the situation: Requested an impossible situation or if you are using the unstableĭistribution that some required packages have not yet been created Note, selecting 'python-gnome2' instead of './python-gnome2_2.28.1+dfsg-1.2_b' Soon they won't just look tired, they will cease to sudo apt install. The bigger question, which Linuxcnc have started looking at seriously, is the completely untenable reliance upon gtk2, glade2 and eventually python 2.7, if trying to distribute something which will run unsupported on existing distros. Python-2.7 still ships, there are still too many libs not ported to 3.0 to ignore it □Įssentially looks like the packaging for Stretch can be used, minus the gladevcp dependency. Gcc-7.2.0-16 does not throw up any further esoteric errors, from those ironed out with gcc-6 □ This means that there is another nail in the coffin of gladevcp, because it is used in editor / viewer Python-gtksourceview2 has been deprecated □ Machinekit builds and runs 'as is' from the same development package list as I use for Stretch □ ![]() Solving 'stuck resolution' problems on headless machines Have done a quick preview of Buster, to see what might be in store.īuster is only Alpha 1 status, so essentially Debian 9, with new kernel, gcc etc but not diverged too far yet Solving bad render problems on headless machines Solving slowness problems on headless machines ![]() Solving black screen problem on Windows headless machines All other users will connect to the desktop of such DisplayOwner.Ģ) Connect to the Enterprise Desktop: NoMachine will create its own virtual framebuffer and the user should be able to specify a custom resolution in 'Display settings': To instruct the Enterprise Desktop to create a virtual display for the user specified in DisplayOwner. RHEL 6 and earlier versions), reboot the machine at runlevel 3:įor the Enterprise Desktop: how to enable the creation of NoMachine display serviceġ) Edit /usr/NX/etc/server.cfg and enable the following keys (remove the prepending #): Note If the Linux system doesn't have systemd (e.g. Or, if you don't know what it is, use the "display-manager" alias:Īt this point NoMachine will create its own virtual framebuffer and you should be able to connect and see the desktop. Use the proper command to stop the X server according to your display manager, for example: You can use any of the solutions above or stop the X server manually, in order to make NoMachine use its own display service: In case of a Linux host it's necessary to reboot the machine or restart the display manager to make this operative.Ģ) Setup Xorg for working in headless modeĢ.1) For NVIDIA GPUs and proprietary driver only, another possibility is to configure X.org to run headless (use -allow-empty-initial-configuration)Ģ.2) Install a Xorg dummy driver by creating fake EDID (Extended Display Identification Data) and use it in nf (EDID are stored in the monitor and read out by the GPU when monitor is connected) ![]() In this case NoMachine doesn't use its own virtual display because it detects that the X server running.Ī common solution, valid for all the supported Operating Systems, is to adopt a fake display dongle (also called 'dummy dongle') inserted in the video card port to simulate the presence of a screen and force the system to take full advantage of the GPU as if a real monitor is connected. This ability, enabled by default in the free edition of NoMachine, can be activated also in the commercial versions (see instructions for the Enterprise Desktop at the end of this article).Ī specific case which leads to black screen on Linux is when the X server is running but it is not rendering because the video card is turned off. NoMachine is able to detect when the X server is not running and run its own virtual display, which is an embedded X server. NoMachine is designed to work out-of-the-box on Linux headless machines provided a desktop environment is installed.
