startx unable to detect video device on remote machine


So I have been bangig my head against the wall and need some insight.

This is the situation. I have a debian linux installed on a hardware without a video card. My goal is to to connect to the hardware via ethernet from a remote terminal. I am logged into the linux system via SSH with Xll forwarding enabled.

I have checked the video device and it is a NVDIA GEForce FX 5200.
PCI setting are bus 1, device 0, function 0. Currently I only have one monitor and the following is the xorg.conf file for the Device section:


Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/input/mice"
Option "Protocol" "ImPS/2"
Option "Emulate3Buttons" "true"
EndSection

Section "Device"
Identifier "Generic Video Card"
Driver "nv"
BusID "PCI:1:0:0"
EndSection

Section "Monitor"
Identifier "Generic Monitor"
Option "DPMS"
HorizSync 28-51
VertRefresh 43-60
EndSection



This is what the log file show me after I attempt to start startx:

(EE) No devices detected.

Fatal server error:

As seen in read the device is there but I am not understanding why startx is not recognizing this.
Below is the output from startx:


(==) Log file: "/var/log/Xorg.0.log", Time: Thu Nov 5 16:58:09 2009
(==) Using config file: "/etc/X11/xorg.conf"
(EE) No devices detected.

Fatal server error:
no screens found
XIO: fatal IO error 104 (Connection reset by peer) on X server ":0.0"
after 0 requests (0 known processed) with 0 events remaining.
Couldnt get a file descriptor referring to the console





Any insight would be greatly appreciated!!!!

I don't think you can just run "startx" using X over ssh. You can only start individual programs, which actually get run on the local X server.

If you want a complete desktop remotely, I believe you need to setup XDMCP, vnc, or freeNX.

Unhappy

Not sure if I completely understand.

My local machine is running windows, thus I have installed Xming and have started a server. As well I have Putty installed and have logged in with X11 option. The DISPLAY on the linux box is set to the local machine with the video card.

What I am trying to do is run "startx" as instructed by some documentation that has been presented to me. If this is incorrect, as you may be indicating this may explain alot, but I don't understand why one could not start startx on its own with the current setup.

Dazed and Confused !!

Okay, I did a quick google and found this thread. Maybe startx is the wrong command for the desktop/window manager you're trying to start.

I've run this using gnome-session. I believe that x-session will work as well.

Unhappy startx failure still

OK update......if anybody is out there that can help still!!

Using Xming as the X server on my local desk top I have been
able the SSH into the linux evironment ( w/ X11 enabled).

Have the ability to run the following:

xclock -> displayed on local dt
xeye -> displayed on local dt

startx -> FAILS with the following:

(EE) VESA(0): Cannot read V_BIOS
(EE) Screen(s) found, but none have a usable configuration.

Fatal server error:
no screens found
XIO: fatal IO error 104 (Connection reset by peer) on X server ":0.0"
after 0 requests (0 known processed) with 0 events remaining.


Have been trying to figure this out for days and cannot figure this out.

HELP!!!

There is a fundamental difference between startx and those other X applications. xclock and xeye are X clients. They use an existing X server (as described by $DISPLAY) to render their output and get keyboard and pointer input. On the other hand, startx is intended to start an X server. Since an X server requires some video hardware in order to run, it bails, just like you see.
I will hazard a guess that what you really want to do is run a desktop, which is normally the second major component of startx. It is completely possible to do this with your Xming server. You will need to find out what desktop you want to run, and poke around in startx (it is a shell script) to find what is done to invoke the desktop application.

Perhaps someone else can provide some details on that.

run 'gnome-session' rather than 'xclock' or 'xeye'. This will open a window with the remote gnome desk top on it. I believe that x-session (or is it X-session?) is the generic form of this command, I'm sure that there's a KDE version as well.

remote x

I think you need to export the display to your local machine. When you ssh into the linux box run this "export DISPLAY=ipaddressoflocalmachine:0.0"

So if I were to log into a linux server 192.168.1.1 with ssh from 192.168.1.2 i would run "export DISPLAY=192.168.1.2:0.0" from the ssh session. That tells the x server to use the display at 192.168.1.1. Then try to startx... but the local xserver on 192.168.1.2 has to be running.

If you have xdmcp setup you can then run:
Xephyr :0 -host-cursor -query 192.168.1.1 -screen 1440x900

and you should get a remote graphical login to the server provided you have that setup in gdm,kdm,xdm, etc...
