Comment 40 for bug 47455

the patch breaks kdm because it enforces a hard-coded $HOME, while kdm sets up its own one dynamically - it's not my fault that the admin and the system have the same user id on unix. :)

the patch is utterly misguided. not any applications, but sudo should be fixed. for su, the x-aware variant sux exists (dunno whether it handles ICEAUTHORITY properly - if not, that's another thing to fix). the same can be done with sudo, either directly in sudo or also with a wrapper script.
