This section describes the changes to the LynxOS environment which may be necessary to successfully run XFree86.
To reasonably run XFree86 you may have to adjust a few system parameters.
On LynxOS 2.5.x and 3.0.x include a line
If you're using the "nv" driver (Riva 128, nVidia TNT, TNT2, GeForce),
you will have to increase the value of the SMEMS parameter in
/sys/lynx.os/uparam.h from 10 to 20.
You should also increase the number of ptys to be able run a couple
more xterms. You may replace
If you're using an Intel PentiumPRO or Pentium II (or higher) class CPU you might want to install the MTRR device driver. This driver enables the XFree86 X server to manipulate the CPU memory type range registers which may improve performance on certain systems.
To install the driver (on LynxOS x86 2.5.0 systems an higher) follow these steps:
# cd / # bash /usr/X11R6/lib/X11/etc/MTRR-Lynx.shar # cd sys/drivers/mtrr # make install
Then add a line
/sys/lynx.os/CONFIG.TBLand rebuild the kernel (see next section).
If you plan to use a PS/2 mouse to the following sections before rebuilding the kernel, if not, you should rebuild the kernel now:
# cd /sys/lynx.os # make install # reboot -N
XFree86 includes support for PnP mice (see also Mouse Support in XFree86). The current LynxOS TTY device driver doesn't allow the necessary manipulation of the RTS line and therefore the support for PnP mice has been disabled for LynxOS.
LynxOS x86 comes with a PS/2 mouse driver. If it is not currently
installed on your system install it with
/usr/bin/Install.ps2mouse. Older versions of this driver
contained code to translate the PS/2 mouse protocol to the format of a
serial mouse, thus you'll have to specify "Microsoft" as the mouse
protocol format. The mouse driver contained in LynxOS x86 patchlevel
015 (and higher) does no longer perform the protocol translation an
therefore can be defined as "PS/2" protocol format.
Currently there is no support for virtual terminal switching once the server has started. Support for this feature may be added in future versions (it requires a patch to the vt100 LynxOS terminal driver).
You will need a free console which the X server will use for keyboard
input. You must disable login on at least one of the four virtual
Output made by the XFree86 X on its stdout or stderr will be lost
after the server switches to graphics mode. The XFree86 4.0.2
server stores its output in
n is the screen number).
When the X server is running output made to other consoles will be lost. After server shutdown the screen contents of other consoles may be inconsistent with what one would expect (i.e. random).
