Xpra 0.13.5 fails with error on glGenFramebuffers

[callegar]

Hi,

working with a kubuntu client (intel graphics) and a kubuntu server (nvidia graphics with proprietary driver). Both 64 bit, both at 14.04 (trusty) ubuntu release.

With latest xpra 0.13.5, server starts fine, but client cannot attach.

When attaching I get lots of errors, where the issue seems to be:

ValueError: glGenFramebuffers requires 1 arguments (n), received 2: (1, c_uint(1L))

Specifically

Traceback (most recent call last):

and more...

Ouch, that was caused by the fix for older versions of pyopengl (r6767).
The fix was tested on older versions, newer versions, but not Ubuntu versions..

A temporary workaround you can use is to disable opengl, either via the tray or via --opengl=no.

Right, I forgot to report it, but disabling opengl was enough to be operative, if not at full performance

Here's the fix: r6787, and the backport to v0.13.x in r6788.

Which broke centos again... re-fixed in r6791, backport in r6792.

I'm rebuilding all the Linux packages with this change as version 0.13.5-3, rather than trying to figure out which versions work and which ones don't.

The trusty packages are done, does this fix the problem for you?

Due to this bug I couldn't connect to my session using 0.13.5 but r6788 fixed it.
