Re-built virtualbox X11 modules and rebooted (thinking it might be an out of date acceleration kernel module), and now the crash occurs with a simple xterm:

This belongs in 0.11: we need a way of detecting virtualbox and/or broken 3D drivers and fallback to the pixmap backing. (as we already do on win32 when we detect the virtualbox DLL)

r5156 changes the way we detect OpenGL on all platforms (see commit message for details), so we now avoid this crash. But I don't like it.

Maybe something like this would do the job?:

widget = some.widget()
gtk.gtkgl.widget_set_gl_capability(widget, config)
widget.realize()
drawable = gtk.gtkgl.widget_get_gl_drawable(widget)

Keeping this ticket open so I can try to find a better way.

Please see commit message for r5161

Please verify that the client still works ok:

• Fedora 19 in virtualbox - the client should no longer crash (previously, it may not have crashed on all combinations of host OS / GPU, versions, etc.. ) and GL should be disabled since we blacklist the virtualbox driver
• MS Windows clients: GL should be enabled (I am unable to test with virtualbox - we disable GL when we detect virtualbox)
• OSX clients: GL should be enabled (I am unable to test as my VM does not have GL acceleration)

OpenGL seems to be working with some applications but with transparency it is failing.

Both test applications crash the client. Works fine with opengl=off. So I guess it might be a good idea to blacklist opengl with VMware driver as well?

OSX and Win clients, with opengl enabled, running on hardware, both work fine with the transparent_colors.py.

And with r5311, we get more readable GL property logging:

r5313 + r5314 blacklist the vmware driver.
r5315 improves gl probing error messages so we can see it blacklisted more clearly:

OpenGL errors:
  vendor 'VMware, Inc.' is blacklisted!

OpenGL properties:
  ...

Tested on Fedora 19 and Fedora 20, closing. Will backport to v0.11.x

Notes:

• Are we blacklisting too many drivers by blacklisting by vendor?
• Some of my Fedora virtual machines use Humper as driver, others VMware... (probably because of installation time driver detection?)
• On a Fedora 19 x86 virtual machine which uses Humper, the gl check crashes after probing on exit (probably garbage collection related)
• if someone finds instances of the vmware driver working properly (maybe under vmware?), then we may want to look at differentiating these instances from the virtualbox driver (not sure how..)
• we will get more testing on the GL / rgb / alpha codepaths in small tooltip windows have transparency issues #500
