Changes made to the Monitor Properties Files require that you regenerate all the SVA X
Configuration Files on all the cluster nodes. See Section 2.4.3.3 for how to do this.
2.4.3.2 Change Monitor Properties Manually
In the event that you need to change SVA X Configuration File properties that are not included
in an SVA Monitor Properties File, you can manually edit the SVA X Configuration Files in
/etc/X11 using your display documentation for specific settings. You need to make the changes
on all the SVA visualization nodes. This is a system administration task requiring root privileges.
In the specific case of the head node or a login node, the node is less likely to be cabled to a stereo
or exotic mono display device, which means it is unlikely that you will need to manually change
their X Configuration File properties. If you do need to manually change X Configuration
properties on either of these types of node, you must make changes to the standard xorg.conf
file. SVA does not place a set of its own SVA X Configuration Files on these nodes as it does on
the rest of the nodes in the cluster.
An example of such a change is to the default resolution on the head node, which is set to
1024x768@60 Hz. This was done to support users with a relatively low resolution display device
(such as an RKM) connected to the head node.
If your have a more capable display on the head node, you can change the /etc/X11/xorg.conf
file to specify the resolution. The default xorg.conf already has a specification for a more
capable display device, and turning it on is relatively straightforward.
To make the change, edit the /etc/X11/xorg.conf config file on the head to change the
specific monitor from RKM to MyMonitor.
Original configuration in file:
#Monitor "MyMonitor"
Monitor "RKM"
New Configuration:
Monitor "MyMonitor"
#Monitor "RKM"
Note that if the cluster is re-imaged, xorg.conf is propagated from the head node to all the
nodes in the cluster, including a login node. If you change xorg.conf on the login node, you
need to have a backup copy available to restore if the cluster is re-imaged.
