After upgrading to Ubuntu Jaunty 9.04 from Hardy remote glx rendering (over ssh or just network) against older servers is not working anymore. This is still a problem in current git (or atleast in current xorg-edgers repo) I've tested against two X servers, verified from other sources: X-Win32 Exceed (third party that I can't be 100% on it's validity) Mac OSX Leopard X11 Server All of which works fine on the same machine when rebooted into Hardy using older xorg stack glxinfo outputs: > name of display: localhost:10.0 > Xlib: extension "Generic Event Extension" missing on display "localhost:10.0". > Error: couldn't find RGB GLX visual or fbconfig xdpyinfo outputs that i have SGI-GLX and GLX extension. I suspect that newer glx client side libs must be needing something not provided by the older servers. I've reported this bug on launchpad "https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/384001" where also logs are available about the issue. Though I'd take it upstream since that bug report seems to be stalled.
Thought i'd just mention that same bug occurs with nvidia binary drivers as x server, and jaunty/karmic as client. I've mentioned it to nvidia, but since the bug is in the client, i suspect the best they can do is work around it for their own server.

I don't agree that it's a duplicate of that issue. LIBGL_ALWAYS_INDIRECT=1 glxinfo still doesn't work with a XWin32 server on a Ubuntu Maveric at least.
