sunray-faq - Interesting tidbits for SunRay users
SunRay is a graphical terminal from sun. This document lists interesting things we found while using these beasts.
This Information refers to SunRay 1.2 and may not be accurate for later or earlier releases.
echo status | mconnect localhost -p 7010
Gives a list of devices and lots of information about each device. Note, this works remote as well.
When you use a Token card to be able to move your session between different SunRays, you may have noticed that your session can suddenly disappear while the token is not inserted in any SunRay. The reason for this is, that as soon as you pull the token from the SunRay utaction starts a 900 second wait period and then kills your session. This default can be changed to some other value by editing the /usr/dt/config/Xsetup file and raise the 900 seconds value to some more appropriate value.
With
xprop -root |grep "_SUN"
you can get some interesting information ... for example the IP number of _your current SunRay in the SUN_SUNRAY_CONN_INFO property.
If you attach a non DDC enabled display to a SunRay, it assumes that
the display wants a resolution of 1024x768. You can then use
utsettings to change to resolution. If your screen can not display
a resolution of 1024x768 you have a problem. Using the following
procedure you can change the default resolution for a SunRay.
Edit the /var/dhcp/dhcptab file and add the following symbol:
DispRes s Vendor=SUNW.NewT.SUNW,32,NUMBER,4,1
You can now use DispRes=X in all the macro definitions of your
dhcptab file. X is a value between 2 and 15 depending on the
resolution you desire.
X Width Height Hz ---------------------- 2 640 x 480 @ 85 3 800 x 600 @ 85 4 1024 x 768 @ 60 5 1024 x 768 @ 75 6 1152 x 900 @ 66 7 1152 x 900 @ 76 8 1280 x 1024 @ 60 9 1280 x 1024 @ 66 10 1280 x 1024 @ 75 11 1280 x 1024 @ 76 12 1280 x 1024 @ 85 13 1024 x 768 @ 85 14 640 x 480 @ 60 15 800 x 600 @ 60
If you wanted to change the default for all SunRays to 1280x1024@75
just add :DispRes=10: to the SunRay-I macro in your /var/dhcp/dhcptab. I is the name of the interface where the Sunrays are attached.
You can also add macros targeted at specific SunRays by using their ethernet address as macro name:
01080020F95B1A m :DispRes=10:
Note the 01 before the actual ethernet address.
Sometimes it is not possible to revive a SunRay even by pressing [ctrl]+[alt]+[Back Space]. The symptom is that only the green lizard shows on the screen of the SunRay device. Sun suggests to run
/opt/SUNWut/sbin/utpolicy -i clear
this has the unfortunate effect of killing off all SunRay sessions as it goes and if only one SunRay is to be revived this is a bit much. We found that the following procedure helps as well:
#!/bin/sh
target=f8be86
cd /tmp/SUNWut || exit 1
. `find . -name "pseudo*$target"'`
[ x$DISPLAY = x ] && exit 1
find . -name $DISPLAY -o -name "*${target}" | xargs rm -rf
grep -v "^:$DISPLAY" config/xconfig/Xservers > Xservers.clean
mv Xservers.clean config/xconfig/Xservers
grep -v _$DISPLAY.environment config/xconfig/Xconfig Xconfig.clean
mv Xconfig.clean config/xconfig/Xconfig
where f8be86 stands for the Ethernet address you determined in step 1.
If you are running SunRays in a multi head configuration with virtual desktops you may have encountered the situation that the XServer refuses to create new windows. This limit can be raised by starting the Xsun process with the option
-clients 1024
this option has to show up in the /etc/dt/config/Xservers config line of the SunRay where this feature should be enabled. This file is managed by the script /opt/SUNWut/lib/utdtsession. Edit this script and replace the line
xsdesc=":%d SunRay local@none $SUNWUTLIB/utxsun :%d -nobanner"
with
xsdesc=":%d SunRay local@none $SUNWUTLIB/utxsun :%d -nobanner -clients 1024"
The utxsun server seems to be able to deal with most options accepted by Xsun. Check the Xsun manpage for inspiration. Now, all new entries in Xservers will have the added option. For existing entries in /etc/dt/config/Xservers use your favorite editor.
When programms 'disappear' then it is very possible that you have turned on the multiscreen option and you changed by accident the screen, having only one screen. Another thing that is 'painful' is to work with a virtual screen. To set things like that on the sunray you are working use the following command.
/opt/SUNWut/bin/utxconfig -r 1280x1024 -s on -m off
This sets the Autosize on (-s on) i.e. disables virtual screen. (-m off) disables multiscreen. To see all options use:
/opt/SUNWut/bin/utxconfig
