Thread: no screens found

  1. #1

    no screens found

    I realize that I may not be posting enough info for an answer right away, but I have been doing searches about this problem and not really finding any real answers.

    I am building a new system and have purchased a GeForce4 PCI card. When running xf86config, I have tried choosing the nvidia GeForce selection, and also just a "generic VGA" selection. Both still give me the "no screens found" error when I try to startx. Is the problem with the video card, or I was also reading that not choosing proper monitor settings will also cause this error? But I have the manual for the monitor and think I am choosing the right things there... ???

    I'm not necessarily looking for an answer (though that would be super), but more of a list of things to check out so I can fix this problem Oh I am running Slack 8.0 if that makes a difference.

    hmm if you have already made an XF86Config you could post it here - so it would be easier to help you - else you could try to make a new one with

    /etc/X11/XF86Config should be the file ..

    I'm on my Win98 box right now, so cutting-and-pasting the config file isn't that simple, but I will try to show you the monitor and card configurations as well as the error message I get when I startx. Hopefully that will be ok...

    in XF86Config:
    Section "Monitor"
    Identifier "MAG19"
    HorizSync 31-80
    VertRefresh 60-100
    End Section

    Section "Device"
    Identifier "Standard VGA"
    VendorName "Unknown"
    BoardName "Unknown"
    Driver "vga"
    End Section

    Section "Device"
    Identifier "GeForce4MX420"
    Driver "nv"
    #VideoRam 65536
    End Section

    Section "Screen"
    Identifier "Screen 1"
    Device "GeForce4MX420"
    Monitor "MAG19"
    DefaultDepth 24

    ** some subsections on Displays...they are all defaults, I didn't mess with them **

    End Section

    Section "ServerLayout"
    Identifier "Simple Layout"
    Screen "Screen 1"
    InputDevice "Mouse1" "CorePointer"
    InputDevice "Keyboard1" "CoreKeyboard"
    End Section
    And here is the error I get from startx:
    (II) Primary Device is: PCI 00:09:0
    (--) Assigning device section with no busID to primary device
    (EE) No devices detected.

    Fatal server error:
    no screens found
    looking above that, it seems as if the "nv" driver does not support the GeForce4 cards. If this is the case (which I now think it is), where do I get updated drivers from? (the box the card came in claimed "complete Linux display and OpenGL drivers support&quot and how do I properly install these drivers to allow this card to work?

    Thanks for reading such a long post and helping me with this basic question

    You could try the nvidia driver from, and follow the readme

    wow...*whap self repeatedly*...this is what happens when you sit in front of something for too long...the obvious answer sits right in front of your nose and gets ignored.

    *flogs self with wet noodle*

    thanks for the link

    Okay...I got the files I needed but am running into problems with the make install on the kernel module. I have read the README but don't quite understand what they are talking about...again I am running Slack 8.0, kernel 2.2.19. I got the tarball file (not the rpm) and when I did the make install, I got these errors

    depmod: *** Unresolved symbols in /lib/modules/2.2.19/video/NVdriver
    /lib/modules/2.2.19/video/NVdriver: unresolved symbol __global_cli
    /lib/modules/2.2.19/video/NVdriver: unresolved symbol tqueue_lock
    /lib/modules/2.2.19/video/NVdriver: unresolved symbol __global_save_flags
    /lib/modules/2.2.19/video/NVdriver: unresolved symbol __global_restore_flags
    /lib/modules/2.2.19/video/NVdriver: insmod /lib/modules/2.2.19/video/NVdriver failed
    /lib/modules/2.2.19/video/NVdriver: insmod NVdriver failed
    make: *** [package-install] Error 255
    The README file says
    If you receive errors about unresolved symbols, then the kernel module has most likely been built using header files for a different kernel revision than what you are running. You can explicitly control what kernel header files are used by building NVdriver from the NVIDIA_kernel tar file with: 'make install SYSINCLUDE=/path/to/kernel/headers'.
    Okay...where would I even begin to look for these kernel headers? When I try to include /usr/src/linux-2.2.19/kernel in the make install, it dumps right out, refusing to do the make. Does this require a kernel upgrade or recompile?

    Thanks in advance

    Just configure the kernel and do a make dep. I think that will do it.

    Re:no screens found

    i usually need to make link in /usr/include called linux to /usr/src/linux/include/linux/ . if /usr/include/linux alredy exists i rename it.e.g.
    mv /usr/include/linux /usr/include/old_sys_headers
    ln -s /usr/src/linux/include/linux /usr/include/linux

    I tried that and got the same errors/results...thanks for the advice though!

    CP, what/how do you configure the kernel? Are there certain things that need to be included in that? Thanks in advance...

    Re:no screens found

    Nevermind the last message...I fixed the problem simply by compiling kernel 2.4.5. Now I can startx with no problems, but when KDE starts up, the resolution is really huge. I only see the top left quadrant of the "screen" (i.e. 75% of the desktop is off the screen). I assume this is something in my XF86Config file, and I will mess with it tomorrow...but thanks again for all the advice and help
