8mb of memory is a recommended minimum for running X. The server, window manager and an xterm take about 4 Mb of memory themselves. On a 4Mb system that would leave nothing left over for other applications like gcc that expect a few meg free. X will work with 4Mb of memory, but in practice compilation while running X can take 5 or 10 times as long due to constant paging.
The easiest way for new users to start X windows is to type:
Error messages are lost unless you redirect them because the server takes over the screen.
startx >& startx.log
To get out of X windows, type: ``
exit'' in the console xterm.
You can customize your X by creating
.twmrc files in your home directory as described in the xinit
and startx man pages.
To start the display manager, log in as root on the console and type:
You can start xdm automatically on bootup by disabling the console getty
and adding the following code to
if [ -x /usr/X11R6/bin/xdm ]; then echo -n ' xdm'; /usr/X11R6/bin/xdm fi
To disable the console getty, change ``on'' to ``off'' in
the console entry in
ttyv0 "/usr/libexec/getty Pc" pc off secure
Under NetBSD 1.4 with the wscons console driver, you must enable a virtual console for the X server first. To do this follow these steps:
cd /dev ; ./MAKEDEV wscons''.
/etc/wscons.confexists. The relevant bits:
#screen 0 - vt100 screen 1 - vt100 screen 2 - vt100 screen 3 - vt100 screen 4 - - screen 5 - vt100
