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): File "/usr/lib/python2.7/dist-packages/xpra/client/gl/gl_window_backing.py", line 436, in gl_expose_event drawable = self.gl_init() File "/usr/lib/python2.7/dist-packages/xpra/client/gl/gl_window_backing.py", line 297, in gl_init self.gl_init_textures() File "/usr/lib/python2.7/dist-packages/xpra/client/gl/gl_window_backing.py", line 245, in gl_init_textures glGenFramebuffers(1, self.offscreen_fbo) File "/usr/lib/python2.7/dist-packages/OpenGL/latebind.py", line 45, in __call__ return self._finalCall( *args, **named ) File "/usr/lib/python2.7/dist-packages/OpenGL/wrapper.py", line 570, in wrapperCall pyArgs = tuple( calculate_pyArgs( args )) File "/usr/lib/python2.7/dist-packages/OpenGL/wrapper.py", line 347, in calculate_pyArgs args ValueError: glGenFramebuffers requires 1 arguments (n), received 2: (1, c_uint(1L)) 2014-06-13 18:47:59,252 using audio codec: MPEG 1 Audio, Layer 3 (MP3) 2014-06-13 18:47:59,425 do_paint_rgb32 error Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/xpra/client/window_backing_base.py", line 339, in do_paint_rgb32 success = (self._backing is not None) and self._do_paint_rgb32(img_data, x, y, width, height, rowstride, options) File "/usr/lib/python2.7/dist-packages/xpra/client/gl/gl_window_backing.py", line 445, in _do_paint_rgb32 return self._do_paint_rgb(32, img_data, x, y, width, height, rowstride, options) File "/usr/lib/python2.7/dist-packages/xpra/client/gl/gl_window_backing.py", line 452, in _do_paint_rgb drawable = self.gl_init() File "/usr/lib/python2.7/dist-packages/xpra/client/gl/gl_window_backing.py", line 305, in gl_init glBindFramebuffer(GL_FRAMEBUFFER, self.offscreen_fbo) File "/usr/lib/python2.7/dist-packages/OpenGL/error.py", line 208, in glCheckError baseOperation = baseOperation, GLError: GLError( err = 1282, description = 'invalid operation', baseOperation = glBindFramebuffer, cArguments = (GL_FRAMEBUFFER, c_uint(1L))
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.
