Excellent question - how is this conclusively determined?  Note I have taken no
explicit action either way, i.e., to enable rootlessness or not.

Looking at the xorg wiki, it appears as though 3 conditions are necessary for
running "rootless":

1. systemd >= 216; OK, I'm at 231 on both machines;
2. start X via xinit; OK, I'm using xinit through startx, not a display manager;
3. if I can summarize, if using a proprietary display driver, such as Catalyst
or Nvidia, need to take an extra step to run rootless; *this may be the issue.*

On the machine where redirection works, I am using the nvidia proprietary
driver; on the machine where the error occurs, I am using the xf-video-ati

So, unless I have step 3 above backwards (which is entirely possible), the
question is how to redirect stderr when running rootless? (If I am in fact
misunderstanding, please explain so a moron like me can understand!)

Thanks for your help.
