Monitor is switched off and on

Dear Sirs,

last week I bought Suse Linux9.3 and installed it at home on my ShuttleX
PC SB51G. When I had finished the installation, I found that the Monitor
is randomly switched off and on when KDE is active. Sometimes I think it
happens more often, when the mouse is moved often. But it also happens
when I only work with the keyboard.

My first idea was to change the driver of the Monitor, because there is a
standard vesa driver automatically installed. But it is hard to find a
fitting one. I have a Fujitsu Siemens SCENICVIEW P20-1.

My second idea was to find a fitting parameter for /etc/X11/xorg.conf and
also change the driver of the graphic-interface. But this is also hard.

Is there someone who can help me?

Best regards

Hans-Günter Horter

It will be good to check resolution.
It may be at the edge what monitor can present, and it shuts off when is
overloaded. How often depends on current graphic on the screen.
To check you can try to use Ctrl-Alt-<Plus_on_numeric_pad> to cycle trough
configured resolutions, and check is there any that is more stable, than
the present one.

Vesa driver is for graphic adapter.
If you don't have manufacturers driver disk, you can try to download driver
from Siemens web site:
http://www.fujitsu-siemens.pt/produc...iew_p20-1.html

Unzip the file and copy P20-1.inf and P20-1.ICM to floppy or CD-RW
Start YaST display configuration, and when you are in monitor setup, select
properties. You will see button "Manufacturer Disk ...". Insert floppy
(CD), press OK and monitor should be configured in few seconds.

That option you can use if above with manufacturer disk fails for some
reason.
Technical data are here:
http://212.66.5.9/index.cfm?fuseacti...content&lid=80
You can access them from same web site used for driver.

That doesn't work I think because there is only one resolution in SaX2
listed.

Ok. I installed it successfully. But the monitor is still switched off and
on. My feeling is that its not so often now as before the monitor driver
reinstallation and it seems to be more often when mouse moves or some
animation is going on on the screen.

As mentioned before, there is only one resolution shown in SaX2:
1600x1200 75kHz 60Hz. This is monitors highest possible resolution as
shown in the handbook. There is an onscreen information display possible,
too. It shows me sometimes 1600x1200 75kHz 58Hz or 1600x1200 75kHz 56Hz.
Where is a parameter to set frequencies?

Sometimes monitor is even flickering when user and password is required
and during the whole login procedure and afterwords. Mostly I restart PC
when I see this.

My neighbour lent me his 15 inch NEC Flatscreen for test. This worked
without any problem.

This time I have two sets of mouse and keyboard. One set is composed out
of a wireless mouse and a wireless keyboard and a receiver and transmitter
unit. This set made problems made problems during the installation of
SUSE9.3 so I substituted it against a simple optical Logitech wheelmouse
and a Cherry keyboard. The wireless equipment was much more comfortable.
Is it possible to substitude it again? But I don't know what consequencies
it has because of my monitor problem.

This sounds like your monitor does not like frequencies that are just
slightly out of tolerance.

In xorg you should see:

<<snip from my xorg>>

Section "Monitor"
Option "CalcAlgorithm" "CheckDesktopGeometry"
DisplaySize 406 305
HorizSync 28-107
Identifier "Monitor[0]"
ModelName "P1500"
Option "DPMS"
VendorName "CORNERSTONE"
VertRefresh 50-160
UseModes "Modes[0]"
EndSection

<<pins>>

you could always limit the vertical refresh by putting some thing like
60-61 and see if that helps, also make sure you have the "DisplaySize"
entered, this is not always present so just add the width and height in
mm.

If the above gives you a black screen then can you post
your /var/log/xorg.0.log please, as this should have the detected rates
and also a bit more info on exactly what X thinks should be the correct
values, maybe the auto detection is a little off for your chipset.

Don`t forget to backup your xorg.conf first by making a copy in
the /etc/X11 dir called something like bak-xorg.conf or whatever so
that you can just rename it to get you old settings back.

Does sound like you monitor is either defective or not very tolerant to
frequencies that are slightly out of spec.

Are the wireless models USB? if that is the case then have you enabled
"dos" or "legacy" support mode for the USB in your BIOS, this allows
USB keyboards and mice to function, some boards will not even allow you
to get into the BIOS to change this with a USB keyboard so it is best
to enable it first with a PS/2 keyboard before you plug them in, or use
a USB -> PS/2 converter ( these normally come with the keyboard/mouse )
I always use these as it seems a waste to not use the ports as they are
designed for it, also it frees up the USB ports and saves overloading
the USB power if you have more peripherals connected, motherboard USB
can only supply a comparatively small amount of power to peripherals
and this can cause problems if you have too many trying to draw power
for stuff, that is why it is always best to put things like USB powered
scanners and wifi dongles in a powered USB hub ( you might see messages
about "overcurrent" if too much is being drawn ).

Animation means lower frame rate, but it shouldn't come to the monitor.
I'll wait for answer to Mark's posting, to see what kind of video adapter is
in the game.

Noticed problems when you moving the mouse or using keyboard can be traced
to moments when CPU is serving interrupts. CPU can be hyperthreading,
multigigahertz, last word of power consumption technology, but it can't
make up for interrupt controller that few moments to long is waiting to
decide who is trying to get CPU attention.

Please check (as root, in console):
# cat /proc/interrupts

See Mark's posting:
VertRefresh 60
is the line where is set vertical frequency. Horizontal is few lines above.

Don't forget advice to backup xorg.conf before any changes.

That section could be place for fast test cycle using manual changes and
restart the X server to see if it helps, but when you are sure that you
have one that is good, go to YaST and repeat the same to be sure that font
sizes etc. is adjusted too.

What happens after rebooting? Works fine?

What screen resolution was used for NEC?
On 15" it couldn't be 1600x1200.

Fujitsu-Siemens can be bad, but I remember Siemens as dependable, even
over-engineered computers.

You can lower resolution to 1200x800@60Hz manually using YaST (SaX2).
That can help to stabilize picture, but can't tell who is the culprit for
the problems, because lesser pixels to handle is good for all CPU, video
adapter and monitor.

Mark explained.

I don't use wireless, but I've installed linux on computers equipped with
wireless mice, where receiver was connected trough mechanical adapter USB
-> Mouse port, and there was no problems at all. I don't know is there on
the market some kind of wireless mice that have receiver that needs
software driver loaded in main memory to interpret data, but if you can't
get it to work with linux than it can be the case.

Ok..here is my monitor section as it was produced from SaX2:

Section "Monitor"
Option "CalcAlgorithm" "CheckDesktopGeometry"
DisplaySize 406 305
HorizSync 30-83
Identifier "Monitor[0]"
ModelName "FUJITSU SIEMENS SCENICVIEW P20-1"
VendorName "FUJSIE"
VertRefresh 55-75
UseModes "Modes[0]"
EndSection

Yesterday I tried VertRefresh 60-61 and even 60. But that had no effect.
Sometimes I think, I m working on the wrong source. If it is defective how
can I go shure that it is the monitor and not the graphics adapter?

Here is my device section:

Section "Device"
BoardName "RV280 5961"
BusID "1:0:0"
Driver "radeon"
Identifier "Device[0]"
Screen 0
Option "Rotate" "off"
VendorName "ATI"
EndSection

I hope you can see which graphics adapter I have.

My /var/log/xorg.0.log has 757 lines. I don't dare to post the whole file.
Only if you say its no problem.

Ok. I will test this next time. You are right. It wasn't possible to
adjust such a high resolution with a 15 inch monitor. I think it was
1028x768.

This is the bit that is leaning me toward the monitor being defective,
if the other monitor worked fine then it is either the monitor which is
bad or the radeon does not like that resolution due to it being
defective.

I suppose the only real way of finding out is to put that monitor on
another computer and see how it handles the same 1600x1200.

I don`t suppose you have Windows on there as well and can test the
monitor with the windows drivers? just to see if it is in fact the
linux side as well?

Or can you take it round your neighbour`s to see how it performs there?

My neighbour's graphics adapter is an older one. It doesn't support this
high resolution.

Does it only do it at this resolution though?

Just wondering if it is the monitor then how does it perform under lower
resolutions?
