Black screen with mouse pointer on MD (0810 alpha 2.28 + updates)

[pga57]

Hi,

I need some help to resolve black screens on 2 of my 6 MDs.
One with a nividia 6200LE video card (TV connected) and the other with an onboard 7100 nvidia (VGA connected).
The AVwizard steep worked with no problem.
I have the black screen (with white cursor) before Sarah and the location configuration.

I've look at all the msgs and wiki articles but don't find the solution.
The 2 MDs worked with Lmce 710.

I have regenerate the orbiters, modify the xorg.conf, switch the xorg.conf with another MD that work, rebuild the MD image, add the 810 updates, downgrade the nvidia driver, etc...
I don't find :-(
 
How can I resolve this ?

Thank's !
Philippe

if X isn't starting then the first step is always to review your /var/log/Xorg.0.log file... read through it carefully for any errors that might indicate why it was unable to connect to the display... usually a valid mode was not found or the driver isn't installed/working properly. This should give you clues as to how to modify your xorg.conf or what driver to install. Either way, if X can't start, nothing else in LMCE will work... so that is probably your blockage...

Humm... I've look at the Xorg.0.log and I think it is not those errors that cause my black screen:

dcerouter_1001027:~# cat /usr/pluto/diskless/72/var/log/Xorg.0.log | grep '(EE)'
        (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(EE) Failed to load module "type1" (module does not exist, 0)
(EE) config/hal: NewInputDeviceRequest failed
(EE) config/hal: NewInputDeviceRequest failed
(EE) config/hal: NewInputDeviceRequest failed

What is the "NewInputDeviceRequest" ?

I have the same error on other MDs and they work very well.
I think the problem come after the X start.
On the screen I have for a few millisecond the orbiter creation screen (I suppose it because it is really quick) and it go away and nothing else.
When I click on the mouse, same things. It come for a few millisecond and go away.

It is very strange.

So do you have another suggestion I can look for ?

Hi,

I saw that you regenerated the orbiter, rebuilt the MD, etc. but have you tried deleting the MD and allowing it to be rediscovered?

[pga57]

Yes, I have try to delete one and rediscovered it but the result was the same.
What append after the AVwizard ? (first I have a cross and after a white cursor, so X is started)
Is there a log file I can look to find (and understand) the steep that block the MD build or launch process ?

Something is wrong but to find it.....

Thank's for your suggestions.

Hi,

So your screen gets to the grey or blank screen with cursor...

...then go to webadmin

...select the Orbiter that belongs to the MD and do full regen

...watch the MD progress regen status - step 1 of 2 building screen 1 of xxx.

After about 20 - 25 minutes Orbiter Generation finished message is presented.

MD screen is black - no cursor.

On the Core from main menu do Quick reload.

So, I guess I'm saying do a full regen and watch it build.  When finished do a quick regen.

After the full regen/quick reload it might still be necessary to reboot the MD.

Hello Pigdog,

thank's for your suggestion but it give not the result i wanted.
I allways have this black screen with white cursor after full regen and all the steps you proposed.

I begin to despair because it is not coherent.

Dear Philippe,

what type of UI did you select in AVWizard?
OpenGL or Alphablending?
If you have  chosen one of them try to go back to basic UI1

As this could be a graphic driver issue with OpenGL
I had similar issues as with new Kubuntu some older drivers are not supported

Hello Peter,

I've just change the orbiter UI from UI2 to UI1 (after a rebuild image and a new AVwizard configuration) and have allways the same result.
I've look at the logs but I don't find something wrong (I'm not a expert).

Here my MD pluto log.
Do you find something that can explain the problem I have ?

Dear Philippe,

with your pluto log nothing is wrong. At least a first sight and based on my knowledge.
I still think there is something wrong with your X setup.
Please post your xorg.conf

Maybe I can find something there

For your information, after a apt-get update on this MD yesterday, I have on boot some "load messages" on the screen (big characters).
So I think that X work correctly.

Like I write before, this MD worked with lmce 710 without problem.
It is the reason why I say something is wrong and it would nice to find it.
I can't imagine I'm (I will be) alone with this problem.

Thank's a lot for your attention.

Hello Philippe,

No I do not think You are alone on this, I think I have it too.

Can You please list the hardware of all the MD´s to figure out what differs.

Hello Stefan,

I have post my hardware list on the wiki.
http://wiki.linuxmce.org/index.php/User:Pga57

The MDs that give problems are #1 and #4.

if you want more information let me know.

Philippe

Dear Philippe,

yes you are right with your assumption that X server is starting.

But the remaining black screen can mean a lot of different things.

First:  I would need to know whether the "cursor" you mentioned in the subject is a text cursor or a mouse pointer?
         If it is a text cursor x.server might be stopped due to a failure --> check Xorg.log or post it
         if it is a mouse pointer it might be a conflict between MD Orbiter and X configuration (render, glx virt desktop .......so many options)  mnain problem you will not really find a hint in Xorg.log

second: get a remote / ssh console  you need to login as root into the MD
            if you don't get root or password is not working check the wiki chroot comand helps to setup the password
 
            make a backup of your xorg.file and delete everything what is not necessary
            check the BusID with lspci and enter into xorg.conf
            make a sudo killall Start_X_Wrapper.sh   to kill the Xserver
            and try startx to see if xserver is starting into KDE desktop
             if yes you can check drivers , resolution and so on.....


the minimum configuration (with VGA connected) xorg.conf:

Section "Monitor"
        Identifier      "Configured Monitor"
EndSection

Section "Screen"
        Identifier      "Default Screen"
        Monitor         "Configured Monitor"
        Device          "Configured Video Device"
        DefaultDepth    24
EndSection

Section "Module"
        Load    "glx"
EndSection

Section "Device"
        Identifier      "Configured Video Device"
        Driver  "nvidia"
        Option  "NoLogo"        "True"
EndSection

So leaving your TV connected you will need to keep the entries:
        Option          "ConnectedMonitor" "TV"                                 
        Option          "TVOutFormat" "Composite"   

In general I would propose for first analysis to go with minimum configuration on an LCD/CRT monitor VGA connected

once this is running with proper nvidia drivers and resolution you can try to reconnect the TV.
Also the monitor configuration in the xorg.conf for sure does not fit the TV set
but this we can see only in the Xorg logfile .


As a general remark: before starting to go into deep try to setup from scratch the MD
      on first starting please be aware that still some installation can happen and might take time - be patient
      for sure you did it already, but I just wanted to mention it .....
      As I spent already too much time configuring xorg.conf I know what might be waiting for you ;-)

Hope above will help to find the root cause.

If startx is not bringing up the KDe desktop try to go for vesa driver
and then find the right driver for your card.

Peter

please also try to switch off the screensaver on th MD

Web Administration
MediaDirector > Software modules -> Edit 
Deselect ScreenSaver

Reload
