I'm seeing this bug with a fresh install of 22.04 server:
```
$ DISPLAY=172.17.0.1:0 glxinfo -i
name of display: 172.17.0.1:0
Error: couldn't find RGB GLX visual or fbconfig
```
This is a Ubuntu-only issue. I am able to successfully run glxinfo over
the network from fully-updated Centos7, Rocky9 & Fedora34 machines.

Title:
ssh forwarded glx returns "Error: couldn't find RGB GLX visual or
fbconfig" against older servers
Status in X.Org X server:
New
Status in mesa package in Ubuntu:
Confirmed
Bug description:
After upgrading to Jaunty 9.04 from Hardy remote glx rendering (over
ssh or just network) against older servers is not working anymore.
Currently i've only tested against two X servers:
X-Win32
Mac OSX Leopard X11 Server
Both of which works fine on the same machine when rebooted into Hardy
(still available on another partition)
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, will attach
the full output later.
I suspect that newer glx client side libs must be needing something
not provided by the older servers.
Let me know what other types of logs that are of interest
