_____________________ Note ______________________
Although the 640 x 480 and 800 x 600 resolutions are available,
Digital does not recommend their use because many X11/Motif
applications make assumptions about minimum screen size.
________________________________________________
To change to any of the other supported resolution and refresh modes,
perform the following steps:
1. Copy the DECwindows server setup template to a command file:
$ COPY SYS$MANAGER: -
_$ DECW$PRIVATE_SERVER_SETUP.TEMPLATE -
_$ SYS$MANAGER:DECW$PRIVATE_SERVER_SETUP.COM
2. Edit the file
SYS$MANAGER:DECW$PRIVATE_SERVER_SETUP.COM
to add the following lines in the Cluster Common or Standalone
Workstation Setup area of the file, along with the other setup options:
DECW$XSIZE_IN_PIXELS == 1024
DECW$YSIZE_IN_PIXELS == 768
DEFINE/SYSTEM DECW$SERVER_REFRESH_RATE 70
3. Invoke the shutdown and reboot process:
$ @SYS$SYSTEM:SHUTDOWN
4. Continue to use the defaults until prompted to reboot and then type Y to
reboot.
