Another follow-up. I tried LIBGL_ALWAYS_INDIRECT=1 when invoking
enlightenment_start. This time I did not get any errors about armsoc not
being loaded, but I still get the pop-up window saying OpenGL is not
supported. So perhaps DRI is required? If so, I still don't know why
enlightenment (efl 1.8.3) is complaining since I have DRI, just not in a
separate driver.
Does anyone know what enlightenment does to determine whether OpenGL is
available and has sufficient capabilities?
Thanks.

OK, a follow-up. I suspect that efl (I am using 1.8.3 by the way) is
doing something to load the DRI driver and is failing if it can't. For
armsoc, the DRI support is built in. So for example when I run es2gears,
it gives a warning about not being able to load armsoc_dri.so but it
continues and works.
I ran enlightenment_start with LIBGL_DEBUG=verbose and got the following:
main init win: 1366x768 for e6
screen region screen 0x1e4bfc0: 0 0 1366x768
libGL: OpenDriver: trying /usr/lib/arm-linux-gnueabihf/dri/tls/armsoc_dri.so
libGL: OpenDriver: trying /usr/lib/arm-linux-gnueabihf/dri/armsoc_dri.so
libGL error: dlopen /usr/lib/arm-linux-gnueabihf/dri/armsoc_dri.so
failed (/usr/lib/arm-linux-gnueabihf/dri/armsoc_dri.so: cannot open
shared object file: No such file or directory)
libGL: OpenDriver: trying ${ORIGIN}/dri/tls/armsoc_dri.so
libGL: OpenDriver: trying ${ORIGIN}/dri/armsoc_dri.so
libGL error: dlopen ${ORIGIN}/dri/armsoc_dri.so failed
(${ORIGIN}/dri/armsoc_dri.so: cannot open shared object file: No such
file or directory)
libGL: OpenDriver: trying /usr/lib/dri/tls/armsoc_dri.so
libGL: OpenDriver: trying /usr/lib/dri/armsoc_dri.so
libGL error: dlopen /usr/lib/dri/armsoc_dri.so failed
(/usr/lib/dri/armsoc_dri.so: cannot open shared object file: No such
file or directory)
libGL error: unable to load driver: armsoc_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: armsoc
libGL: OpenDriver: trying /usr/lib/arm-linux-gnueabihf/dri/tls/swrast_dri.so
libGL: OpenDriver: trying /usr/lib/arm-linux-gnueabihf/dri/swrast_dri.so
So it is complaining about the DRI driver (armsoc_dri.so) , not the main
video driver (armsoc_drv.so). Is explicit load of the DRI driver by efl
to check if it is there, and if so, can someone tell me how to turn it
off or comment it out?
The problem may not be this at all, but I would like to eliminate this
issue as a possiblity.
Thanks.

Hi guys. I am trying to get the OpenGL composite support working with
the latest e17 enlightenment on Samsung Chromebook (armhf) running
debian jessie. When I try switching to OpenGL it pops up the message box
saying it can't be done. According to Jeff Hoogland, the OpenGL stuff is
compiled into evas etc. I have GLS2 installed and in fact I now have
es2gears running fine.
Is e doing something special or unusual to check for the proper OpenGL
support?
I did run enlightenment_start under strace and I did see a message of
the form:
libEGL error: failed to load driver: armsoc
Obviously armsoc loads fine or X would not even work. And I don't get
this complaint from anything else, including es2gears. The armsoc_drv.so
is under /usr/lib/xorg/modules/drivers via a soft link. I tried changing
its group to video (saw this suggestion somewhere) and added the user to
the group but it didn't help.
At this point I don't know if the libEFL error is a red herring or the
real issue. Can someone give me some clues as to how I might track this
down?
Thanks.
