Yes, that's very possible. If I know what process to attach to.
gnome-shell? or Xorg?

I did run top once, and everything was idle, no run-away process.

I can try that. But do I need to install any other packages to get ELF
symbols? When I attach to gnome-shell for example I get lots of "no
debugging symbols found" and this...

   Missing separate debuginfos, use: debuginfo-install

But debuginfo-install is not a recognized yum command. So what's needed?
