Package: x2goserver

Version: 4.0.1.19


When I connect to a x2go server that has an nVidia GPU using nVidia's
binary drivers most software (such as Firefox, Thunderbird, Cheese,
Transmission GUI etc.) will segfault on launch.

This can seemingly be fixed by setting the LD_LIBRARY_PATH variable to
wherever the nVidia drivers are (i.e. for nVidia-361 drivers just run
LD_LIBRARY_PATH=/usr/lib/nvidia-361" in the server's terminal.
Alternatively it seems that you can switch to the Noveau driver and the
issue won't occur, but this might not always be an option.

There's also a thread on ubuntuforums
(https://ubuntuforums.org/showthread.php?t=2337814) that also has a
video of this bug in action.

I'm using Ubuntu 16.04 with MATE.

i ran into this issue on ubuntu 16.04 (64 bit), and i can confirm that both
workarounds (using Nouveau and setting LD_LIBRARY_PATH=/usr/lib/nvidia-375
) fix the issue.

to add a bit more info, it seems that in the failing case, glxinfo (or
presumably the other apps), can't find the GLX_indirect library that it
trys to load dynamically, which has something to glvnd:
https://github.com/NVIDIA/libglvnd

looking at ldd, you can see that glxinfo is finding the GL libraries fine,
using the system-set ld.so.conf settings that the nvidia driver sets up:
moskewcz@mari:/etc/ld.so.conf.d$ ldd /usr/bin/glxinfo
    linux-vdso.so.1 =>  (0x00007ffe4779c000)
    libGL.so.1 => /usr/lib/nvidia-375/libGL.so.1 (0x00007fcd87f35000)
    libX11.so.6 => /usr/lib/x86_64-linux-gnu/libX11.so.6
(0x00007fcd87bfb000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fcd87831000)
    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007fcd8762d000)
    libGLX.so.0 => /usr/lib/nvidia-375/libGLX.so.0 (0x00007fcd873fd000)
...

the paths are set here:
moskewcz@mari:/etc/ld.so.conf.d$ cat
/etc/ld.so.conf.d/x86_64-linux-gnu_EGL.conf
/usr/lib/nvidia-375
/usr/lib32/nvidia-375

using strace, we can see the difference that setting LD_LIBRARY_PATH makes:

# working case, opens the correct lib:
moskewcz@mari:/etc/ld.so.conf.d$ LD_LIBRARY_PATH=/usr/lib/nvidia-375 strace
glxinfo 2>&1 | grep GLX_ind
open("/usr/lib/nvidia-375/tls/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) =
-1 ENOENT (No such file or directory)
open("/usr/lib/nvidia-375/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = 4

# non-working case, fails to open libGLX_indirect.so:
moskewcz@mari:/etc/ld.so.conf.d$ strace glxinfo 2>&1 | grep GLX_ind
open("/lib/x86_64-linux-gnu/tls/x86_64/libGLX_indirect.so.0",
O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("/lib/x86_64-linux-gnu/tls/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC)
= -1 ENOENT (No such file or directory)
open("/lib/x86_64-linux-gnu/x86_64/libGLX_indirect.so.0",
O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("/lib/x86_64-linux-gnu/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1
ENOENT (No such file or directory)
open("/usr/lib/x86_64-linux-gnu/tls/x86_64/libGLX_indirect.so.0",
O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("/usr/lib/x86_64-linux-gnu/tls/libGLX_indirect.so.0",
O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("/usr/lib/x86_64-linux-gnu/x86_64/libGLX_indirect.so.0",
O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("/usr/lib/x86_64-linux-gnu/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC)
= -1 ENOENT (No such file or directory)
open("/lib/tls/x86_64/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1
ENOENT (No such file or directory)
open("/lib/tls/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No
such file or directory)
open("/lib/x86_64/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT
(No such file or directory)
open("/lib/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such
file or directory)
open("/usr/lib/tls/x86_64/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1
ENOENT (No such file or directory)
open("/usr/lib/tls/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT
(No such file or directory)
open("/usr/lib/x86_64/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1
ENOENT (No such file or directory)
[...snip many more repeats of failed-to-load libGLX_indirect...]


however, it's not clear why, under x2go, the nvidia code isn't searching in
/usr/lib/nvidia-375 -- but it's not clear what code it uses for the DL
loading, maybe it is somewhere in the glvnd code.
