Display Problem

[Sanjaya Balasuriya]

Hi guys,

My server is HP-UX B.11.11 U 9000/800.
This has a display related problem.

It does not give any out put to the monitor. When the minitor is connected is setting indiacator bulbs atart to blink and nothing comes to the monitor.

I tried taking this server's display to another Linux server using "X -query". It works fine.

Any clues to sort out this puzzle ?

Thanks in advance.

First use a simple console and the display type and frequency and resolution of the type of monitor that you want to use then connect your monitor back. That will work. Remember you will see those display option settings during bootup.

oopss I ment SET the display type and resolution

[Steven E. Protter]

Try this in /etc/profile

DISPLAY=$(who -m -u | awk '{print $8}'):0.0
export DISPLAY


It may fix your problem.

Thanks for the answers.

But my DISPLAY is correct.

I also suspuect that the problem may be related to monitor resolution settings. I tried to set it to 1024x768. But it's always changed back to 1280x1024.

Or is it about drivers ?

How can I know what are the installed drivers ?

(I'm new to HP-UX :) )

Did you also check the frequency along with the resolution. Try various combinations.

Take a look at the settings on the monitor. Some monitors have frequency settings that may be interfering.

If you are using an L-class or rp54x0 server with the graphics card, the setmon doesn't write correctly to non-volatile RAM, so after a reboot, the system is back to the default. There is a work around I can send you if this is your situation.

Hi,

with 'graphinfo' you get infos about your graphic card and the installed graphics core and libs.

Do you have a monitor which works at the server? Which type is it?
Which type do you want to use?

From my experience, the best is to use SAM to do it, but you need a working monitor to do that. I also tried changing monitor setting in SAM after rlogin to a ws, but that didn't worked for me.

There can also the setting of the graphics path be wrong!
So do you have a monitor which works?

Make sure you have a mouse and keyboard connected.

Check the file /etc/dt/config/Xservers and see that this line near the end is no commented out-
* Local local@console /usr/bin/X11/X :0

Look for error messages in /var/X11/Xserver/logs/Xstartup.0.log .

Hi Ted/Sanjay

I am facing the same display resolution problem in my rp5470 system installed with HPUX 11, Please send the workaround.

Sorry, hadn't check these messages in a timely manner. Please see the attached file.

hello sanjaya,

Edit /etc/X11/XF86Config and go the end of the file.There you will find a line pertaining to resolution with the value "1240x1024".Change the entry to "800x600" and reboot the server. This will solve your problem.

[Heiner E. Lennackers]

Take a look at the setmon command:

/opt/graphics/common/bin/setmon

"setmon -r" will show you the available modes your graphics cards is able to handle.
"setmon -s " will set a mode. get with "setmon -r". Take a mode your monitor is able to handle.
You should stop your X server before you do it or it will be terminated automatically when you change the mode (without giving you the possibility to stop any running program on it)

On the L-class or rp54x0 servers, setmon is not persistent through a reboot, so you have to add the files mentioned in my prior post. I is a bug that I have never seen fixed, but the workaround solves the problem.
