With the default US keymap you can use Shift with the PageUp and
PageDown keys (NB: these must be the grey ones, not the ones on the
numeric keypad!). With other keymaps check the maps in
/usr/lib/keytables
; you can remap the ScrollUp and ScrollDown
keys to be whatever you like -- for example, in order to remap them
to keys that exist on an 84-key AT keyboard.
You can't increase the amount of scrollback, because of the way it is
implemented using the video memory to store the scrollback text, though
you may be able to get more scrollback in each virtual console by reducing
the total number of VC's -- see <linux/tty.h>
.
-------------------------------------------------------------------------------
In text mode, press Left Alt-F1 to Alt-F12 to select the consoles
tty1
to tty12
; Right Alt-F1 gives tty13
and
so on. To switch out of X windows you must press Ctrl-Alt-F1, etc;
Alt-F5 or whatever will switch back.
If you want to use a VC for ordinary login you need to list it in
/etc/inittab
, which controls which terminals and virtual
consoles have login prompts. NB: X needs at least one free VC in
order to start.
Kernels earlier than around 1.1.59 have a compiled-in limit on the
number of consoles, for which the default is 8. See
NR_CONSOLES
in linux/include/linux/tty.h
. Newer
kernels allocate them dynamically, up to a maximum of 63.

Change directory to /usr/lib/zoneinfo
; get the timezone
package if you don't have this directory. The source is available as
sunsite.unc.edu/pub/Linux/system/admin/time/timesrc-1.2.tar.gz.
Then make a symbolic link named localtime
pointing to one of
the files in this directory (or a subdirectory), and one called
posixrules
pointing to localtime
. For example:
ln -sf US/Mountain localtime ln -sf localtime posixrulesThis change will take effect immediately -- try
date(1)
.
Don't try to use the TZ
variable -- leave it unset.
You should also make sure that your Linux kernel clock is set to the
correct GMT
time -- type date -u
and check that the
correct universal time is displayed.

Type:
uname -a

Linux now has corefiles
turned off
by default for
all processes.
You can turn them on
or off
by using the
ulimit(1)
