Please help! Sooooo many hours trying to figure this out, should be simple I think but I'm not a sophisticated user of Linux.
The Gem objects appear properly when I open the windows, but whenever I try to open/create a gemwindow, it immediately crashes (however, it seems to respond when I change the data - for instance, I can see color changes when i make those changes, but again, the gem window crashes immediately...)
A possible solution lies here but haven't been able to get a response when I attempt to implement this

Why does Gem crash when creating the Gem-window? !
When I try to create a Gem-window, my X-server crashes (or worse)? btw, I am using Ubuntu/hoary with fglrx drivers.
quick
try setting the environment variable GEM_SINGLE_CONTEXT to 1
explanation
Gem establishes an (invisible) openGL-context at startup, even if no Gem-window is created yet. When you create the Gem-window, a 2nd openGL-context is used (which shares some properties with the invisible context).
For some reasons this seems to be not possible with some gfx-drivers (e.g. ATI's proprietary fglrx drivers) and some window-managers (i suspect compiz/beryll), leading to crashes of the X-server and/or system freezes.
The current workaround is to set the environment variable GEM_SINGLE_CONTEXT=1, which prevents this dual-context magic.
how?
if you are starting Pd from the bash, you can start Pd/Gem with GEM_SINGLE_CONTEXT=1 pd -lib Gem
on bash, you can also set this permanently by adding a the line export GEM_SINGLE_CONTEXT=1 to either ~/.bashrc (the bash-configuration file in your home-directory) or to /etc/bash.bashrc (to set it for all users)

- newer linux user but though I followed compiling instructions for installing Gem, it seems never to create a conf file.. when I open pd-extended in terminal, I get this message:
open: ./gem.conf: No such file or directory
any thoughts or input would be VERY APPRECIATED, thanks!
