Ubuntu 16.10 XRDP + nvidia + GLX not working #721

Open lieff opened 7 years ago

lieff commented 7 years ago

I'm trying to use opengl through rdp connection. I've enable indirect rendering through +iglx X startup option and AllowIndirectGLXProtocol. Logs reported that everything is normal:

[     3.665] (II) LoadModule: "glx"
[     3.665] (II) Loading /usr/lib/x86_64-linux-gnu/xorg/extra-modules/libglx.so
[     3.723] (II) Module glx: vendor="NVIDIA Corporation"
...
[     3.736] (**) NVIDIA(0): Option "AllowIndirectGLXProtocol" "on"
[     3.736] (**) NVIDIA(0): Enabling 2D acceleration

But inside XRDP session GLX cannot be used:

$ glxinfo
name of display: :10.0
Error: couldn't find RGB GLX visual or fbconfig

Using strace I've noticed that it cannot find libGLX_indirect.so.0, so I tried:

$ LD_LIBRARY_PATH="/usr/lib/nvidia-378/" glxinfo

Is it possible to use nvidia GLX within XRDP session? Or software mesa glx or VirtualGL must be used?

lieff commented 7 years ago

I can get VirtualGL work, but on modern distributions it's very tricky (because of security I suppose). We need two users: user1 and user2. We must login user1 on console (which creates display :0 with nvidia glx). Then we login user2 through xrdp. If we just try to use VirtualGL, it failed:

user2$ /opt/VirtualGL/bin/vglrun glxgears
Invalid MIT-MAGIC-COOKIE-1 key[VGL] ERROR: Could not open display :0.

Security does not allow us to use others display, we need su user1:

user2$ su user1
Password: 
user1$ /opt/VirtualGL/bin/vglrun glxgears
14188 frames in 5.0 seconds = 2837.502 FPS
15110 frames in 5.0 seconds = 3021.876 FPS

And it worked! I don't know how to make xrdp glx usage more simple for now.

@lieff were you using VNC to connect to the session or xorgxrdp?

If you had used xorgxrdp driver you could have used mesa gl, but you would have to remove the GLX drivers from Nvidia, since this would prohibit you from creating an X Session. This is due to the xorgxrdp driver not supporting Nvidia's GLX implementation, unless you have libglvnd in the distribution which will allow multiple GLX implementations to co-exist on the machine and it will route those GLX implementations appropriately.

VirtualGL is a alternate option as well but it has caveats with some software, I do know if you run the gnome desktop VGL will get caught up handling the desktop and completely unable to render applications.

lieff commented 7 years ago

I use xorgxrdp session. I know about libglvnd and I can get it work too, but only with nvidia+software GLX, so.. software will be used, not hardware. It can be done even without libglvnd by switching paths to software GLX (we do not need nvidia part if its not working). But I want hardware GLX of course, so we need some working way to connect to nvidia GLX. VirtualGL works, but with security bypass tricks. So, to make it more user friendly, we need some solution on this...

fang64 commented 7 years ago

@lieff VirtualGL is a good option but you will have to still leverage the Mesa Libs for the desktop rendering, otherwise you'll have issues getting applications to render while the desktop is using the hardware.

What I found is I had to create application wrappers to solve the security issue to make it "user friendly" although I ran into issues with applications that were written poorly. For example having a path full of application wrappers that overrides the normal executables for applications so the user calls those instead. Ideally with the environment configured for vgl_run and the application to run properly.

You could also write a generalized wrapper, but those almost never work for "all applications" especially commercial applications that have their own wrappers that like to break out of the shell they are being run from.

lieff commented 7 years ago

Software mesa libs can't run all applications, we need hardware support (from MESA and proprietary drivers). What I see about user friendly solution: XRDP among with sesman starts console user login and creates host display for this user (through systemd I suppose, not really sure how to make this step). Then it setup GL path to VirtualGL, so we do not need vgl_run (which only loads appropriate GL so to app). And bingo, opengl should work through XRDP. This may also require changes in VGL, because we must tell it hardware host display number through system variable or something.

stebo85 commented 7 years ago

Dear lieff and fang64, Has anyone made some progress on this problem? Since we upgraded to Ubuntu 16.04 we have the same issue with xrdp and we can't run GLX applications in XRDP or SSH + X forwarding in combination with the nvidia driver. For an SSH+X connection it is possible to define LD_PRELOAD=/usr/lib/x86_64-linux-gnu/mesa/libGL.so and then things work again via mesa:

Is it possible to force xrdp to run via mesa as well? I would be happy with software rendering. In which ini file would I need to put LD_PRELOAD=/usr/lib/x86_64-linux-gnu/mesa/libGL.so to make it work?

We also tried the workaround via "/opt/VirtualGL/bin/vglrun application" but this only works for a few days and then something crashes and we have to restart the server to get it working again.

Thank you for any hint :) Steffen

lieff commented 7 years ago

@stebo85 vglrun probably stops working when X11 server crashed (I've seen this on CENTOS systems with buggy GLX/GL client code). X11 crashed because of nvidia glx module, so only newer driver/X11/system can help.

Hmm software mesa should always work, but note that libGL.so can load other .so files, and it must be not from nvidia driver. You can use strace to see what happen.

tycho commented 6 years ago

So I ran into this too, on Arch Linux. libGL.so is the vendor-neutral version (glvnd), so depending on what Xorg driver is loaded, it will get directed appropriately to NVIDIA's libGL or Mesa's. The problem for me seems to be that NVIDIA provides a file called /usr/share/X11/xorg.conf.d/10-nvidia-drm-outputclass.conf which adds the NVIDIA glx module to the search path before the Mesa one:

Section "OutputClass"
    Identifier "nvidia"
    MatchDriver "nvidia-drm"
    Driver "nvidia"
    Option "AllowEmptyInitialConfiguration"
    Option "PrimaryGPU" "yes"
    ModulePath "/usr/lib/nvidia/xorg"
    ModulePath "/usr/lib/xorg/modules"
EndSection

I tested out commenting the NVIDIA OutputClass section and GLX seemed to work fine over Xrdp, but this obviously breaks GLX for users physically at the machine.

Presumably if there was an xorg.conf.d file loaded after this with an OutputClass section that only loaded when using the xorgxrdp driver, then it would be possible to re-insert the Mesa module path earlier in the load order. I just can't figure out any OutputClass section that would work, since the MatchDriver directive only seems to match kernel drivers (and I don't see any other Match* directives for the OutputClass section).

EDIT: Interesting, if I add this to /etc/X11/xrdp/xorg.conf, things are fine:

Section "OutputClass"
    Identifier "nvidia"
    MatchDriver "nvidia-drm"
    ModulePath "/usr/lib/xorg/modules"
EndSection
cminnoy commented 5 years ago

This issue is still relevant for Ubuntu 18.02. After adding the above section to /etc/X11/xrdp/xorg.conf GLX applications, like Blender now work under RDP. Great. Unfortunatly I still don't have hardware acceleration for GLX, only software acceleration. Things like RemoteFX which is supposed to work when the client is in LAN mode and color depth is 24bit should theoretically work, but the logs ~/.xorgxrdp.% indicate otherwise.

(EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not found)

lieff commented 5 years ago

Also relevant for Ubuntu 19.04. Software render also can be enabled by modify .bashrc file and point path to software mesa libGL like:

if [ "$XRDP_SESSION" = "1" ]; then
export LD_LIBRARY_PATH=/path/to/mesa/lib:$LD_LIBRARY_PATH

Hi guys ! I'm trying to understand this. I am using a Jetson Nano from NVIDIA, operating system is release 18.04.4

I am trying to access remotely through my windows computer (remote desktop). But once I am entered, the sessions closes immediately.

This is my xorg.conf file.

Hi @romybompart

Have a look at #1582 where we looked into what may be exactly the same Jetson issue. There are some logs from that issue that you can compare with yours. There's also a link to the NVidia developers forum where you'll find more information.
