[winswitch] trying out xpra/winswitch

[Neal Becker]

I'm baffled.  If I start emacs via xpra (using xdummy), it looks great.  If
I start via winswitch it doesn't.  It looks like it's set to a lower
resolution.

Both clients and servers are fedora f17 linux.

Within each of these emacs sessions, I ran xdpyinfo and xrandr.  Both
outputs show no difference.  I compared the two Xorg.:7.log, Xorg.:62.log,
and don't offhand see any significant diff (because of the timestamps,
comparing these files I just did visually).

I have no ideas how to debug this.  I'd like to use winswitch for the nice
features, but emacs under xpra looks beautiful while emacs under winswitch
looks bad.

I was wrong about my guess that winswitch was not using xdummy.  I see that
Xorg was started with the same command line in both cases.

Any ideas?
