[SOLVED - Simple How To Attached] Screenshot of Login Screen? - XDMCP

[MoonRise]

I've done a lot of searching on how to be able to do this with no luck. All links were how to do this with GDM and not KDM. I've created my own Login Screen, but would like to have a preview shot of it. How!!! Anyone? Is there not a tool out there that can take the XML configuration and display the Graphical result?

Re: Screenshot of Login Screen?

One way to do preview shot of login screen:

Alt + F2 :kdesudo kate /etc/kde3/kdm/kdmrc
There is:

[Xdmcp]
Enable=false

=>

[Xdmcp]
Enable=true

Alt + F2 :kdesudo kate /etc/kde3/kdm/Xaccess
There is:

#*					#any host can get a login window

=>

*					#any host can get a login window

Restart (or restart kdm)

In the konsole:

:~$ Xephyr -query localhost -screen 800x600 :1

Use KSnapshot...

Note
You can use different resolution or -fullscreen option

Cool!!! Thanks!!!

Re: Screenshot of Login Screen?

Hmmmm. OK. Did all that and all seems fine, but the resulting screen is the familiar X grey scren with the X cursor. Any ideas from that?

Also enabling those entries seem to be keeping kicker from starting automatically. I can start it manually though.
Sorry, that one was me
Still get the grey screen.

Re: Screenshot of Login Screen?

Any errors in the konsole when you start Xephyr ?


Have you tried with xnest ?

Xnest -query localhost :1

or
With :2, :3,...

One relating to a FONT. Don't think that's it though. Do I need to do this? Found it through Google.

X(XOrg) configuration

To configure a multiterminal with N terminals, edit the file /etc/X11/xorg.conf, and do the following:

1. Define a layout with N screen's.

Section "ServerLayout"
    Identifier   "Layout"
    Screen     "Screen 1"
    Screen     "Screen 2"  Below  "Screen 1"
    Screen     "Screen 3"  Below  "Screen 2"
    .
    .
    Screen     "Screen N"  Below  "Screen N-1"
    InputDevice   "Generic Keyboard 1"
EndSection

2. Define one Device Section for each video card:

Section "Device"
    Identifier   "Video Card 1"
    Driver     "sis" 
    BusID      "PCI:0:5:0"  
    Screen     0    
EndSection   
    #
    # Change the video card driver and the BusID according to you hardware.
    #
    # The BusID option identifies your video card. To obtain the BusIDs of your video cards,
    #use the command "lspci | grep VGA".
    # Beware: the lspci command shows address in hexadecimal, while X expects decimal numbers.
    #The command "echo $((0xHEX_NUMBER))" is your friend.
    .
    .
    .
Section "Device"
    Identifier   "Video Card N"
    Driver     "sis"
    BusID      "PCI:0:6:0"
    Screen     0    
EndSection

3. Define the Monitor Sections.

Section "Monitor"
    Identifier   "Monitor 1"
    HorizSync    30-71
    VertRefresh   50-160
    Option     "DPMS"
EndSection           
    .
    .
    .        
Section "Monitor"
    Identifier   "Monitor N"
    HorizSync    30-71
    VertRefresh   50-160
    Option     "DPMS"
EndSection

4. Define the Screen Sections

Section "Screen"
    Identifier   "Screen 1"
    Device     "Video Card 1"
    Monitor     "Monitor 1"
    DefaultDepth  24   
    SubSection "Display"
        Depth      24
        Modes      "1024x768" "800x600" "640x480"
    EndSubSection
EndSection
    .
    .
    .
Section "Screen"
    Identifier   "Screen N"
    Device     "Video Card N"
    Monitor     "Monitor N"
    DefaultDepth  24   
    SubSection "Display"
        Depth      24
        Modes      "1024x768" "800x600" "640x480"
    EndSubSection

Re: Screenshot of Login Screen?

Same thing with xnest. Grey X screen with familiar cursor. Also for screens 2, 3, and 4.

Re: Screenshot of Login Screen?

Do I need to do this? Found it through Google.

Hmm - i didn't need. I only enabled Xdmcp and 'any host can get a login window'.

Hmm#2 - What happens if you:

:~$ startx -- /usr/bin/Xephyr :1

It should start another xsession in the Xephyr window. But there is a bug report:
xephyr crashes when trying to run a gutsy session
https://bugs.launchpad.net/ubuntu/+s...er/+bug/122610.


I think that those instructions are for multiterminal (single computer which supports multiple users at the same time). =>

Re: Screenshot of Login Screen?



Thanks!!!!!! That worked!!

startx -- /usr/bin/Xephyr :1

[Rog131]

Re: Screenshot of Login Screen?

Hmm - do you get login sceen with startx ?


About Xephyr (login screen):

Maybe:

:~$ Xephyr -query 127.0.0.1 :1

works.

Re: Screenshot of Login Screen?

No. Been trying since I lasted posted. Goes directly into another session of mine and when logging out of it closes out. Never see the login screen. It also tried to put it to the Full screen width. I'll try what you just wrote and let you know. I don't give up. This is the furthest I've gotten.

[MoonRise]

Re: Screenshot of Login Screen?

Xephyr -query 127.0.0.1 :1

Same result. Grey as far as the eye can see

[MoonRise]

Re: Screenshot of Login Screen?

Well. I thought it may be doing that because I had Compiz running. Turned all that off, rebooted and tried again. Still grey.

Re: Screenshot of Login Screen?

OK. Lets backup here. How did you install? I use adept manager and what ever they had in the repos. Do you know of any other dependencies that maybe are not loaded as necessary? This is on my desktop. I'll try the laptop soon.

I'm using Synaptic (+apt in the konsole). I don't think that the problem is in dependencies. Problem seem to be in the graphical login.
