Re: [VirtualGL-Users] [TurboVNC on Ubuntu 12.10] No menu

[DRC <dco...@us...>]

Don't waste your time.  I've spent many many hours on this problem. 
It's not a bug.  It's just that, unfortunately, the developers at the 
bleeding edge have mandated that "thou must have OpenGL" in order to run 
the latest & greatest window managers, and the reality seems to be that 
"thou must also have hardware-accelerated OpenGL".  Not only do you need 
H/W acceleration in order to achieve any kind of decent performance with 
the WM, but I don't think compiz even works with Mesa ... or at least, I 
was never able to make it work.  The latest version of VirtualGL (2.3.3) 
can run compiz, but this support is still very experimental, and I do 
not recommend it for any kind of mission-critical deployment.

Basically any distribution other than Ubuntu 12.10 and 13.04 should work 
great.  Our project is geared toward enterprise deployments, so we 
really try to focus on the "enterprise" distributions-- SuSE Enterprise, 
Red Hat/CentOS Enterprise, and Ubuntu LTS.  Most people who deploy 
VirtualGL/TurboVNC commercially use one of those (with RHEL being, by 
far, the most used of the three.)  Also, as previously stated, you can 
run XFCE or another 3rd-party WM under Ubuntu 12.10+, and that works 
great as well.  You just can't run Unity 3D.

We are not the only X proxy vendor who is running headlong into this 
issue.  There are some commercial implementations that are struggling 
with how to address this as well.  Also, TigerVNC currently exhibits the 
same issue, even though they have a built-in software OpenGL renderer. 
It's actually worse, in fact.  With TigerVNC, the entire desktop image 
is inverted, in addition to having no menus.  It's going to be 
interesting to see what Red Hat does for RHEL 7.  They'll either have to 
solve this problem or continue shipping a 2D WM that can be used with 
TigerVNC.
