I stumble upon an error while trying to run League of Legends (through PlayOnLinux) with optirun. I got these errors: ERROR: ld.so: object 'libdlfaker.so' from LDPRELOAD cannot be preloaded: ignored.ERROR: ld.so: object 'librrfaker.so' from LDPRELOAD cannot be preloaded: ignored.As stated in the doc, I try to check if the virtualgl-libs:i386 package is installed. However, it seems that this package does not exist anymore or its name has changed.
I'd like to know its new name, could you help me?I've found a package called virtualgl. But when I run sudo apt-get install virtualgl:i386, it returns an error saying that (approx translation from french): No version of the virtualgl:i386 package is available, but it exists in the database,This means that the package is missing, obsolete or only available through an other source.No version of the 'virtualgl:i386' package can be installedAny idea or suggestion?
OS: Opensuse 42.3NoMachine: NoMachine Workstation6.7.611x8664A default install has been completed. VirtualGL has been enabled.The system works very well for user1.However I am unable to launch VM’s for a user, unless that user is already logged into the server/host machine and has DISPLAY:0 running.i.e.If User1 is logged in (running:0), VMs can be created and accessed.But if I attempt to create a VM for user2, errors.If I then login as user2 (running:0), VMs can be created and accessed.But then User1 can no longer create VMs!Am I missing something?Or is a ‘NoMachine Small Business Server’ required to launch multiple desktops; virtual or physical?ThanksJoe. Hi, to clarify, all Terminal Server products let you run virtual desktops, and they can also give you access to the physical desktop. In your case, Workstation will allow up to 4 virtual desktops. Small Business provides up to 10.
Mac OS X users who update to XQuartz 2.7.9 will discover that they. The VirtualGL tool ( ) intercepts the OpenGL calls,. In this video, you will learn how to install Windows 10 on your Mac using VirtualBox. Link to download Windows 10: https://www.microsoft.com/en-gb/software-d.
Both allow access to the physical display. So swapping for Small Business will simply increase the number of virtual desktops you can run.I am unable to launch VM’s for a userBy VM I imagine you mean a NoMachine virtual desktop. In the Terminal Sever family the virtual desktop functionality allows individual multiple Linux desktops to run on the same host sharing the same OS, which is different to running virtual machines each with their own operating system ?VirtualGL has been enabled.Did you follow the instructions here?How to enable VirtualGL support on Linux in NoMachine v. 6.2 or laterIt’s important to know that VirtualGL requires access to the display:0 and the reasons for that are explained here:Why VirtualGL requires access to the display:0You also mention errors.
There is a good article with workarounds for trouble-shooting VirtualGL. Does this help?Troubleshooting problems when enabling VirtualGL support for NoMachine virtual desktops. Hi,Thanks for your rapid response. Digging through these suggestions it is clear I might have deeper issues.On restarting the server/host machine I can no longer see any display:0 (as expected) or load a virtual desktop (Makes sense if VirtualGL requires access to the display:0)Opening a console into server/host machine to start display: liam@NEESON: startkdeInvalid MIT-MAGIC-COOKIE-1 keyNo protocol specifiedVGL ERROR: Could not open display:0.startkde: Starting up.Invalid MIT-MAGIC-COOKIE-1 keyNo protocol specifiedVGL ERROR: Could not open display:0.kdeinit5: Communication error with launcher. This is weird behaviour and we are investigating further.
Are you using GDM as the display manager?openSUSE comes with SDDM, so I guess it is the display manager in use in this case.I found an openSUSE system with a similar issue: it looks a race condition prevents SDDM scripts to enable local access tothe X server. So let me provide the following tips:1. Check the script /etc/X11/xdm/XsetupIf VirtualGL setup changed it correctly, the command:xhost +LOCAL:is placed at the beginning of the script.2. In that case, change the Xsetup script to add 5 seconds delay to thexhost command (waiting in background):( sleep 5; xhost +LOCAL:) &3. Repeat steps 1 and 2 for script /usr/share/sddm/scripts/Xsetup4.
Restart sddm:systemctl restart sddm5. Try again to get a virtual desktop6. Retry DISPLAY=:0 xhost, in the remote session.
Output should be:access control enabled, only authorized clients can connectLOCAL. Thanks for the support. Sorry for my delay.Yes – SDDM is the display manager.1.The first line in /etc/X11/xdm/Xsetup is xhost +LOCAL:It appears VirtualGL setup changed it correctly.2/3. Sleep command was applied to both: /etc/X11/xdm/Xsetup and /usr/share/sddm/scripts/Xsetup4. Sddm was restartedI still cannot open a virtual desktop with user2.
I received the error “the connection with the server was shutdown”In DISPLAY:0 as user1(liam), xhost returns:access control enabled, only authorized clients can connectLOCAL:Should be possible for user2 to spawn their own virtual desktops. Even when DISPLAY:0 belongs to user1?
