I think I have to clarify some points...
1) I started by doing step by step what is in the user guide. But as long as I
using an headless computer, the user guide doesn't help me straight forward. I
took a look in the mailling list, and in google of almost all occurences with
headless and virtualgl... but I didn't found the solution, so if you think
about a mail I would be happy to read it...
2) about the "-x" option for vglconnect, the user guide says "this mode
performs optimally on local-area
networks" what I'm doing here. I don't have to encrypt or to securise anything.
But at anytime i read it's a legacy mode... and I still want to remember the
fact that without "-x" I got
X11 forwarding request failed on channel 0
your answer was,
Same issue as the vglclient error above. For whatever reason, either
>the X server is not running on your client machine, or X applications
>are unable to make connections to it (perhaps because DISPLAY isn't set.)
X is working on client, but I didn't deal with DISPLAY at any moment. So I
tried (client),
set DISPLAY=:0
but,
/opt/VirtualGL/bin/vglconnect user@SERVER
still return,
X11 forwarding request failed on channel 0
I didn't read anything about having to set DISPLAY in the user guide... the
only occurence is in exceed section
before trying to use virtualgl, I used nomachine, there was no problem with X
forwarding (but it's not usable for opengl rendering).
4) I'm sorry if my mails looks like drafts, it's the first time for me to use a
mailling list and my english isn't the best I know it... I still don't know if
it's correct to use bold, italic, whatever... or just straight text... over all
I ask myself I have to let the last mail below what I'm writing... I'm also
sorry for didn't told you on wich computer I typed the commands, I'll take care
of that in futur mails.
5) I tried this morning to install turbovnc (1.2), I download and compil it on
both client and server. But thanks to the documentation there should be
/opt/TurboVNC/bin/vncserver actually isn't here. there is vncserver in
.../turbovnc-1.1.90/unix . So don't know what to do here, just root cp never
sound clever...
6) not sure what you mean here (maybe my english) :
> after some research, I did this,
>> [root ~]# chmod u+s /opt/VirtualGL/lib/libdlfaker.so
>> [root ~]# chmod u+s /opt/VirtualGL/lib/librrfaker.so
>> after reboot, I still got same errors than before.

because, I downloaded the src from sourceforge, I didn't customised anything
(excepted FindTurboJPEG.cmake to reach the good directory)... anyway, I created
two symbolic links ont the server,
ln -s /opt/VirtualGL/lib/librrfaker.so /usr/lib/lib/librrfaker.so
>ln -s /opt/VirtualGL/lib/librrfaker.so /usr/lib/librrfaker.so
7) in one xterm I ssh my server to startX with the user account, then in a
second xterm I vglconnect the user to the server, then I got,
name of display: :0
>display: :0 screen: 0
>direct rendering: Yes
>(...)
from
/opt/VirtualGL/bin/glxinfo -display :0since I created the two links, when I try
to launch something via vglrun on the server I don't have anymore the libs
error. then I tried by adding the "-d" option to vglrun to be sure that the
display :0 is used (on the server),
/opt/VirtualGL/bin/vglrun -d :0 etracer
I got,
*** etracer error: Couldn't initialize SDL: No available video device
don't know what to do...
anyway thx for taking time to read and to try to help me...
