By default Lilo gives two options of OS to start, Windows and Linux, and wait a minute to run automatically the first option. I just have Slackware in my PC so it is unnecessary that Lilo asks and wait.
To change the default Lilo behavior you have to change /etc/lilo.conf, this is what I have changed.
# Wait until the timeout to boot (if commented out, boot the
# first entry immediately):
2. No Windows option. Comment or delete the Windows section at the end of the config file:
#other = /dev/sdb1
#label = Windows
#table = /dev/sdb
To apply any modification to the boot loader it is necessary to run the command lilo.
Configuring the system to multi user with session manager
Most of the time I use KDE, so I prefer start KDM it when the system goes up. To do that you have to change the default runlevel configuration in file /etc/initab to the option 4:
# 4 = X11 with KDM/GDM/XDM (session managers)
# Default runlevel. (Do not set to 0 or 6)
After booting in runlevel 4 the computer showed an error with the sound card and didn't play any sound. This is because in runlevel 4 users don't belong the audio group, so you have to add your user to it.
# usermod -aG audio user_name
This problem can affect other resources, as scanners, printers, etc the solution should be adding the user to the appropriate group.
Network manager configuration
In this distribution KDE gets its own network manager, if you want to use it just changes permissions of rc.networkmanager:
# chmod 755 /etc/rc.d/rc.networkmanager
In case you prefer wicd, you have to install it from /extra/wicd folder in the Slackware installation DVD and change permission to /etc/rc.d/rc.wicd to 755 after installation.
