Do 'su -' and that will give you root's environment and that will give you
the proper .Xauthority which will let you start X. At least that's how I
think it works.

I'm hoping that you started the X session as a regular user ?
The quickest fix I found for this was to not the DISPLAY variable as set
via the user (the one who started X), and then just export that variable
in the su session. There's probably a cleaner solution than that, though.
If you're only running a single command, you might want to try `su -c
app_to_run'. Just have to be careful that if you're running anything
with more than one arguement that you quote the entire thing. That is,
do:
su -c 'vim .Xdefaults'
and not: su -c vim .Xdefaults
There is another method of invoking su which gives you the privalege of
being root without setting any new variables. I forget how to get it,
though.

I doubt this much fiddling is necessary, in all probability his distro has
set up a script called pon to do all that for him...
try just typing pon (poff to disconnect)

RAM is cheap, buy some more. Even a Windoze box likes to have at least
128MB and better is 256MB.

Definitely! However, if memory is an issue for one reason or another, try
dispensing with gnome or kde. Both like memory resources available. There
are nice and light in memory window managers like blackbox and icewm.
Windowmaker is not too bad. Personally, I have stopped use gnome and I
never used kde. What I use is the latest windowmaker by itself in debian
unstable with a few nice dockapps and I use wmakerconf to configure the
thing.
I really cannot imagine using gnome with only 32mb of memory. You must have
a lot of patience :)

Just as easily one could use wvdial which is a console based ppp dialer and
you only have to edit the /etc/wvdial.conf file for your particulars. I use
it on the road or when I do dialup. That actually is not so much anymore
since most hotels that I tend to stay in have fast internet acccess.

Building and adding a new kernel does not mean that you have to discard
your old working kernel. Edit /etc/lilo.conf and change the label for the
"linux" kernel to "old" then add a new section for the new kernel setting
its label to "linux". That way you can always choose "old" at the LILO
prompt.

Partition Magic revision 4 will resize Linux ext2 partitions. I expect later
revisions will work just as well or better (revision 4 was released before
Linux supported swap files bigger than 128 megabytes, and will only create swap
partitions that big, I don't know if later versions fixed this). Note, if you
resize or move the partition the kernel is on (either the / or /boot partitions
depending on your setup), you must boot from floppy or rescue disk, since the
disk addresses LILO has put into the master boot record will have changed.
Many of the distributions now ship the GNU Partition editor (parted). I
personally haven't tried it, but it might work for you (you would need to boot
from rescue disk mode).

Youre using linux right? I would suggest you play around with smail,
sendmail or one of the other linux programs. A simple search for linux mail
servers will probably yield you a pretty large list. Running Microsoft
products is just an all around bad idea. Microsoft corp doesn't even use
their own products because of all the security problems. Unless you want to
download a huge bloated program to handle your mail. I would suggest using
a package that came with your linux distribution.

Greetings all,
I recently setup Red Hat 7.1 on my i386 machine. I was happy to see that
I can finally use my Sony Spressa (CRX 100) CDRW/USB device under Red Hat.
Here's the thing, however, if I turn my CDRW on before I boot into Linux,
and it is the first Linux boot of the day (I'm on a dual boot
machine), then the Sony device drivers seem not to load and the CDRW
does not appear in /mnt. Every other Linux boot of the day, however,
brings up my CDRW just fine...it is detected, I can burn CDs , etc. So,
I usually have to boot the machine into Linux at least twice before I
burn any discs/use the CD-ROM. This is strange. What could be causing
this? Better yet, what are the tools, etc. used to control USB
configuration?
Thanks in advance to all who reply.

OK, I have unpacked a game named tictac into usr/tictac. After installing the game
just as its
manual said (make, make install) I had the compiled game files in usr/tictac and
another executable
in usr/games. My guess was that I should start the game by running the one in the
games directory.
OK, I've tried the following:
- double-click on it from File Manager
- write "tictac"
- write "./tictac"
- run it from File Launcher
... and I've tried this with both executables (in usr/tictac and usr/games).
What am I missing here?

And, before you "su", in your user account type "xhost+localhost"
(opening up X security for anyone on 127.0.0.1) then after "su -" do:
export DISPLAY=:0.0

I hear a new release is coming out soon, this from the author
Christian Gebauer who was kind enough to reply to a previous post.
He also said the search function for newsgroup titles would be improved to
allow for individual display of titles rather than the tree view.
Perhaps this "save" problem will be fixed as well.
