Yes, XDG_RUNTIME_DIR is problematic, but as "su -" doesn't work in GNU Screen (it yields major display issues), I presume that some environment variables (terminal related?) are still useful. FYI, I had written a su wrapper that unsets XDG_RUNTIME_DIR first. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
