libgl udev permissions and gphoto problems! [SOLVED]

I'm having an odd problem. Udev isn't setting permissions properly, and it seems to be intermittent. I've only noticed it with plugging my creative zen player into amarok.

I'll get a can't reclaim USB device error. Restarting udev

/etc/start_udev

Will often solve the problem, but it isn't always needed. It seems almost random after  reboot

As well, not sure if its related I get this error

$ glxinfo | grep dri
libGL error: open DRM failed (Operation not permitted)
libGL error: reverting to (slow) indirect rendering

Again, intermittent. I have the 0666 line in xorg.conf, a reboot or restart of X will often clear this up.

And to top it off, my SD200 camera no longer connects with gphoto (I've done some research with this one, and it looks to be a bug in gphoto2 but I though I'd just mention it in case an Arch user has found a fix).

Seriously, I've never had this many things break on me at once, all things that used to be stable and reliable.

Try to look to my similar problem, I have the same effects than you with a temporary fix:

But I have no answer to understand why unfortunately !!!

what camera do you have, as far as I've researched there is an issue with SD200-500 or so, with gphoto2

It is a canon EOS 350D and a Ixus 850

Re: libgl udev permissions and gphoto problems! [SOLVED]

So the two were slightly related. Whenever I restart udev (which is almost everytime I need to use my mp3 player) it breaks permissions for libgl:

[blah]$ glxinfo | grep direct
direct rendering: Yes

[blah]$ sudo /etc/start_udev 
mounting... ramfs at /dev
Creating initial udev device nodes:
Kernel >= 2.6.15 and supports uevents
udev startup is finished! - time = 10

[blah]$ glxinfo | grep direct
libGL error: open DRM failed (Operation not permitted)
libGL error: reverting to (slow) indirect rendering
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)
OpenGL renderer string: Mesa GLX Indirect

Still no idea why.

well sort of, I just don't run into my libgl breaking due to never having to restart udev. Gphoto is still broken but that's another issue entirely.
