Post-installation instructions for X.Org on OpenBSD/sparc64

Single, unaccelerated display
|
|
-----------------------------
|
|
This setup is by far the easiest to configure and is supported on just
|
|
about every machine OpenBSD/sparc64 runs on (both PCI and SBus based
|
|
machines). These setup do not require any configuration file.
|
|
|
|
To use xenodm from rc.conf.local(8), it is necessary to disable
|
|
/dev/console in /etc/ttys, change the 'status' of /dev/console to
|
|
'off'.
|
|
|
|
Single, accelerated display
|
|
---------------------------
|
|
Accelerated access to the framebuffer is supported on machines with
|
|
PCI VGA or UPA Creator framebuffers.
|
|
To use a PCI VGA framebuffer, retrieve the PCI bus, device and function
|
|
of the video card, eg:
|
|
|
|
blade$ dmesg | grep vgafb
|
|
vgafb0 at pci0 dev 19 function 0 "ATI Rage XL" rev 0x27
|
|
wsdisplay0 at vgafb0: console (std, sun emulation), using wskbd0
|
|
|
|
The framebuffer is on bus 0, device 19, function 0. Now, create
|
|
/etc/X11/xorg.conf, with the following content (replace 0:19:0 with the
|
|
bus:dev:func of the framebuffer):
|
|
|
|
Section "Device"
|
|
Identifier "Card0"
|
|
BusID "PCI:0:19:0"
|
|
Option "composite_sync" "True"
|
|
# Use the following option on Blade-100
|
|
# Option "reference_clock" "29.5MHz"
|
|
EndSection
|
|
|
|
Section "Monitor"
|
|
Identifier "Monitor0"
|
|
HorizSync 31.5-70
|
|
VertRefresh 50-90
|
|
EndSection
|
|
|
|
Section "Screen"
|
|
Identifier "Screen0"
|
|
Device "Card0"
|
|
Monitor "Monitor0"
|
|
EndSection
|
|
|
|
See xorg.conf(5) for more options. You may want to replace the frequency
|
|
ranges in the "Monitor" section with the actual ranges supported by
|
|
your monitor.
|
|
|
|
For UPA Creator framebuffers, the device will be automatically detected
|
|
and you don't need to have an xorg.conf file.
|
|
|
|
Dual, unaccelerated display
|
|
---------------------------
|
|
Dual-headed displays are only supported on machines with SBus framebuffers.
|
|
These configurations will require a configuration file.
|
|
Create /etc/X11/xorg.conf, with these two sections for each framebuffer:
|
|
|
|
Section "Device"
|
|
Identifier "Wsdisplay0"
|
|
Driver "wsfb"
|
|
Option "device" "/dev/ttyC0"
|
|
EndSection
|
|
|
|
Section "Screen"
|
|
Identifier "Screen0"
|
|
Device "Wsdisplay0"
|
|
EndSection
|
|
|
|
This example is for the first screen. For the others, increment the
|
|
"Wsdisplay" and "Screen" numbers, and change the device to /dev/ttyD0
|
|
for the second display, /dev/ttyE0 for the third, and so on.
|
|
|
|
Then, you'll need to create a ServerLayout section describing all the
|
|
displays and their location relative to the first, as in:
|
|
|
|
Section "ServerLayout"
|
|
Identifier "wsfb"
|
|
Screen 0 "Screen0"
|
|
Screen 1 "Screen1" RightOf "Screen0"
|
|
EndSection
|
|
|
|
See xorg.conf(5) for more options.
|
|
|
|
To use xenodm from rc.conf.local(8), it is necessary to disable
|
|
/dev/console in /etc/ttys, change the 'status' of /dev/console to
|
|
'off'.
