Normally you would set up X during the install including the
resolutions. If you didn't do that correctly, either use xf86config
from the commandline (text based simply read write and your done...)),
or do it directly by hand:
the usual solution then is to edit the /etc/X11/XF86Config file and add a
default colordepth line to force 8 bit = 2^8 = 256 colors, 16 bit =
2^16= 65536 colors or 24 or 32 bit ("==>"s are not part of the file, just
pointing to the interesting lines!) as done below.
The modes descibe the resolutions a particular colourdepth can use. They
are probed in the order they appear in, so in this case the Xserver will
first try the default 16-bit colour at 1024x768, then if that doesn't
work try at 800x600 or 640x480. So in your case simply make sure that
fi "1600x1200" is the first of the modes. Now the reason that by default
the most conservative setting is used is that when one uses settings
which are out of reach for your monitor, it can burn out eventually.
Most modern monitors can handle nearly anything you throw at them but
older ones would fry at the wrong settings.
from the /etc/X11/Xf86Config file (almost all the way down, the file
starts first with loads of comments and modelines)
A relatively userfriendly text editor for the novice user is pico.
Log in as root, type on the commandline "pico /etc/X11/XF86Config"
edit the lines which aren't to your liking and save the changes by
typing Ctrl+X.
>From my /etc/X11/XF86Config
.....
Section "Screen"
Driver "svga"
Device "My Videocard"
Monitor "My Monitor"
==> DefaultColorDepth 16
Subsection "Display"
Depth 8
==> Modes "1024x768" "800x600" "640x480"

EndSubsection
Subsection "Display"
Depth 16
==> Modes "1024x768" "800x600" "640x480"

EndSubsection
....
The maximum setting you can use is dependant on the amount of memory you
have, as the memeory usage is determined by the formula;
H-res times V-res times Colordepth equals Memory needed.
Thus for 1600x1200 at 32 bit one needs 1600*1200*32=61.44*10^6 bit, or
7.5 Mbytes of video memory on the card.

sndconfig from the comandline but for any sound advice (in both senses)

Okay, I never got the part that this was a windows installation.
Can't help you.
I'd say, if you want to give linux a try, give it a real install.

extract from `man 4 vcs`
/dev/vcs[1-63] are character devices for virtual console
terminals, they have major number 7 and minor number 1 to
63, usually mode 0644 and owner root.tty.
so 07:07 is a virtual console.
Still sounds odd to me.

Hello,
you should use the latest via-rhine driver module for the DFE-530TX.
They changed a chip with the revision B I think.

Not sure if NT will accept this. D: is a logical drive. Some OS's insist

You shouldn't make two partitions active. The default DOS MBR could get
confused.
If you use LILO, it doesn't really matter

FIPS???
Use diskdruid or fdisk.
FIPS is used to split an existing FAT partition into two parts.
As the free space lies beyond 8GB it surely passes the 1024th cylinder.
Therefor you may have problems booting from that space if you insatll an
OS there.
Make a small partition for linux, /boot, that lies entirely below
cylinder 1024.
For the rest I don't see any problem with linux.
How to install, depends where the free space is.
Is it inside hda2 (the extended partition) or is it only usable for
primary partitions
You should read the partitioning HOWTO (search the web for it)

Place /var and/or /tmp on one of the other partitions

change this to boot=/dev/hda2
then run `/sbin/lilo -v`

Doesn't sound right.
Try supplying the correct parameters when you boot
root=/dev/hdXXXX
If that still fails, search /dev for the correct major and minor number
of the root partition, and supply those, eg.
root=major:minor

Wouldn't work for us. We have a single system generating four displays,
which will be going to the RH boxes. SGI has in their Xlogin script a
thing like this:
============
# visuallogin: on: clogin; off: plain xdm login
# also, "-f" in clogin means grab input focus
# to allow remote login to execute commands ( use displays ) on this machine
# when no one is logged in, delete the $1 at the end if the clogin command exec
if /etc/chkconfig visuallogin ; then
if [ -x /usr/Cadmin/bin/clogin ] ; then
# exec /usr/Cadmin/bin/clogin -f $1
exec /usr/Cadmin/bin/clogin -f
fi
fi
============
What I'm looking for is a similar construct in the Linux world, and was
hoping that someone would know offhand what it is. (I've already spent
many hours looking at FAQs and examining code; it'd be nice if someone
knows the answer and could save me some time. :-)

I need to do all this via a script.
(ie...similar to autoexec.bat/config.sys)
This has to be a single click via GNOME first login as root on the desktop (shortcut)

Is their a way?

Reply-To: "E.M. Stegehuis \(Marcel\)" <[EMAIL PROTECTED]>
A while ago I shifted from RH6.2 to RH7.0. Although the system runs smoother
there is a small problem. Rexec, which ran perfectly before, didn't ran
anymore. (I posted before, but was unable to solve the problem as it ended
up in a discussion about using rexec/rsh).
Does anyone had the same problem and solved it.
I use Starnet's Xwin-32 (http://www.starnet.com/)
NOTE: I don't want to give root access via rexec/rsh.
I included some files of which I thought would be handy to find the problem.
Merci beaucoup,

It would help if you did. Set it up as a caching name server and add
primary zones for your domain name and your network IP numbers.
Then this DNS server can resolve internal as well as external names and
IP numbers.
However, if you run a http proxy on the gateway machine your internal
systems won't need to resolve hostnames for web browsing.
