So is there a workaround? In my case, I'm trying to access an OpenCL gpu
from a userland container. I was assuming that the below might be
enough.
lxc.mount.entry = /dev/dri/card1 dev/dri/card1 none bind,optional,create=file
lxc.mount.entry = /dev/dri/renderD128 dev/dri/renderD128 none
my downstream package suffers from this: https://github.com/opencog
/link-grammar/issues/530

fwiw: me too - I'm hitting a related bug; same timeframe I assume
similar reasons. Debugging now.

Recommend closing this bug... Here's why.
TL;DR: libopencv-dev provides /usr/share/OpenCV/OpenCVConfig.cmake etc
I experienced a bizarre bug, though:
On xenial (16.04), having a CMakeLists.txt with a find_package(OpenCV
REQUIRED) gave me an error:
CMake Error at CMakeLists.txt:9
... except that /usr/share/OpenCV/ already contains the required files!
So, in principle, find_package(OpenCV REQUIRED) should just plain work.
So why doesn't it? ??

... except that I am unable to find any version of FindOpenCV.cmake that
actually works with the OpenCV that is provided in trusty or xenial
(14.04 or 16.04) -- one of many problems is that the way that the opencv
version numbers are specified is not compatible with how version numbers
used to be
It appears that one can be downloaded from here:

Bug
Hi Christopher,
I spent 2 or 3 16-hour days trying to bisect this bug every-which way.
I eventually punted, and just bought a newer graphics card -- they're
cheap -- a few hundred $$ and that fixed the problem.
Summary: the old card works great under ubuntu 12.04 but has issues, as
described
Public bug reported:
/usr/bin/env hangs when a variable is set. To reproduce this, create a
file with the following contents:
#!/usr/bin/env A=B python
; !#
(display wtf)
(newline)
lets say the file was wtf.sh. Then chmod ugo+x wtf.sh and then
execute it: ./wtf.sh This will hang and spin
I woke up this morning, and I get this error message. What happened?
-- it was working last night.
-- ssh-add -l says everything is there.
-- above means that ssh-agent is running
-- contents of /tmp and /tmp/keyring-XXX look OK
-- SSH_AUTH_SOCK=0 ssh wherever works
System: ubuntu 14.04
Uptime:
Basically, this means that there's no utf8 support, which means that
almost any non-Eglish language fails.
Appearently, this was/is a package build bug; the support was always
there in the sources, and was just not being built for the package.
typical symptoms:
nm

These Xorg errors seem to be a side-effect of X hanging in
uninteruptible sleep, in the kernel: i.e. a nouveau kernel module issue.
At least for me. See the bug I just quoted for details.
