(For PCs) To synchronize the timer-tick clock according to the more accurate battery-powered clock:
/sbin/hwclock --hctosys
/etc/inittab
In addition to /etc/rc.d/init.d, /etc/inittab specifies programs to be started during boot. Eg, Mandrake uses inittab to launch KDE via kdm.
To change the time-zone (eg to US Eastern Time):
1. Edit TZ in /etc/profileEg, export TZ="America/New_York"
2. Link /etc/localtime to /usr/share/zoneinfo/America/New_York
To synchronize the date/time according to a remote machine:
rdate hostname
If backspace does not work, try: stty erase ^h
To restore the keyboard rate (in a console):
kbdrate
To restore keyboard auto-repeat (in X Windows):
xset r
To restore keyboard auto-repeat (in X Windows):
xset r
To prevent the screen being cleared by login after boot, add --noclear to the line with mingetty in /etc/inittab.
Console video modes:
"vga=" is a kernel parameter which either can be passed at the LILO prompt (eg "linux vga=normal") or stored in /etc/lilo.conf (run "lilo" again).
```
vga=normal
vga=extended  # 50 lines
vga=788       # graphical (used in Mandrake 8.0)
```
Configuring a standard PC joystick with an Ensoniq AudioPCI (ES1317) sound card:
The joystick device file will be /dev/input/js0
Add these lines to /etc/rc.d/rc.local (kernel must compiled with these modules).
```
modprobe joydev
modprobe es1371 joystick=0x200
modprobe analog
```
Loading PLIP (the parallel port network driver) kernel modules:

modprobe parport
modprobe parport_pc
modprobe plip

Installing Nvidia's proprietary video driver on Debian 3.
It won't install unless a new kernel is compiled with CONF_MODVERSIONS. I chose the build-from-source option using Nvidia's curses-based installer. Then edited 2 or 3 lines in /etc/X11/XF86Config-4 per Nvidia's README. That was all. You'll know it's working if you see Nvidia's splash screen while X starts.
Adding your favorite window manager to gdm menu.
Eg, to add icewm, create your own /etc/X11/gdm/Session/Icewm script. gdm will automatically find it and add it to its menu. Also, you can add your own X configuration setting to the script. For example:
```
#!/bin/sh

# Faster mouse.
xset m 4 4

# Start window manager.
/usr/X11R6/bin/icewm
```
