No it doesn't to some distros, like this pclos. I can ssh -Y into that
box, but I cannot run the main gfx applications like emc even though I am
the same user on both boxes.
Example: (having just logged in so the session is fresh)
gene at shop:~$ emc -l
EMC2 - 2.4.6-76-gf8ea663
Machine configuration directory is '/home/gene/emc2/configs/genes-mill'
Machine configuration file is 'genes-mill.ini'

Shutting down and cleaning up EMC2...
EMC terminated with an error. You can find more information in the log:
as well as in the output of the shell command 'dmesg' and in the terminal
And except for the above msg, no other clues for the failure are given in
any of those named files. IIRC I even posted that here before, but quite
some number of months back up the log, and I don't recall getting a helpful

I have a lappy, but it also has pclos on it. IIRC it also reports the same
problem although TBT I haven't tried it recently. I am currently trying to
get a belkin router to function as an AP in the shop. and have had to
reset it many times because it disappears. NDI what I am doing wrong other
than my local net is not on a 192.168.1 or 192.168.2 address block, another
security measure. There is nothing precious on the lappy, so I could put
10.04 LTS on it I guess, but I want to get rid of the cat5 cable I'm always
tripping over first.
