I can help with some the questions you have asked.

1. slackware uses a BSD style init system. Look in the /etc/rc.d directory. There you will find the the different rc. files used. The numbered ones are the run level. The others are indicated by the name. Use rc.local for own config commands.

2. I do not know what linuxconf is so I am unable to respond.

3. If you have configured the X system, starting X from the shell is done by the command startx. I think the default window manager is set by "xwmconfig". It should ran when you installed Slack and you were allowed to make your choice. But you may run it again if you desire another default.

4. I think what you are looking for is the default run level. That is set in the file /etc/inittab. Modify the default from 3 to 4. Do not use 5 like other distros. I would not change this until you have a stable X configuration. It starts X and calls xdm for the graphical login manager.

5. I do not use dialup on my Linux workstations except from the shell level. Perhaps another here can provide more advice. I use the pppd daemon and chat scripts in the /etc/ppp directory. There is a HOWTO on the subject.

6. To install Slack prepared packages use "pkgtool" else get the tarball source, extract, build, and install.

7. I do not know if a command exists for reporting partitions. I use the program "cfdisk" to view the hard drive and the partitions.

8. To view the current message buffer use "dmesg". In X scroll the window back up to view all the lines. From the console use [Shft]-[PgUp] to scroll the screen backwards. I know [Shft]-[PgUp] also works in a X console if it is configured for a Linux console/keyboard, etc.

Also, you might be interested in the log files and almost all are stored in the /var/log directory, like /var/log/messages. There are few in other places but are specific for individual apps.

Hope that it has been of some help.

I'll add to some that Excaliber didn't go into detail with that might be of some more help.

Nothing like linuxconf in Slackware. Most other distro's don't even use this as its buggy and unstable at this point. Most of the other GUI's in other distro's is their own software they provide.
With Slackware, its mainly configuring by hand. That is what makes it so beautiful though. Slackware makes their configuration simple and easy to configure actually. They have kept it the same basically thru every release since the beginning, not changing it around like other distro's.

You can also use fdisk -l to list all the partitions along with the corresponding devices on your system with Slackware. This makes it easier than just starting up the cfdisk program to view the partitions to me. But cfdisk works as well though, but using the fdisk -l will just print out the info at the command line and then take you back to a prompt.

The xwmconfig will be global for all users. If you want one particular user to load kde as their default desktop, you can always create a symlink of .xinitrc in the user's home directory to the correct xinit file in /etc/X11/xinit directory in which your case would be the xinitrc.kde
Slackware has all these files ready for use in selecting your desktop environment. So to set this up for a particular user you could do something like this:

ln -s /etc/X11/xinit/xinitrc.kde /home/user/.xinitrc

But be sure you are logged in as root to run that command or it will give you permission denied.

Hope this helps out some as Excaliber pretty much covered it all as well.
