    Default LCD Monitor not detected (How to configure ?)

    Have a problem with the LCD (LG Flatron L177WSB) Monitor.
    On trying to access the 'Graphics Card & Monitor' section from [YaST Control Center] and [Control Center] (both these are: click Computer on gnome desktop --> under 'System' column on the right), & putting the root p/w the screen goes blank, goes back to command prompt (Login : ) and then in a few secs back again to GUI (gnome desktop) by itself...I am unable to change the Monitor Refresh rate [currently 51 Hz, found thro' Control Center --> Screen Resolution (this works)] from 51 Hz to 60 Hz (optimal).

    I would like to add the specific LG Flatron Monitor (L177WSB) & load it's driver, if available (currently it is displayed as just 'Monitor' from the 'Hardware Info' tab of YAST Control Center).

    How can I configure/add the Monitor to detected hardware.
    The default Screen Res of 1440 X 900 is supported as I could install the nVidia GeForce 8400 GS drivers.

    Post Re: LCD Monitor not detected (How to configure ?)

    As the xorg.conf file points to many Monitors (& so I have no idea which one to edit/delete (if needed) & how), I have the zipped the /etc/X11/xorg.conf file. It can be d/led from -

    http://lvznow.bay.livefilestore.com/...f.zip?download

    or

    Hi
    Have a read here if your only using the default driver 'nv';
    http://en.opensuse.org/Nvidia

    I've never had much luck with either the 1-click or openSUSE nvidia
    repositories and have always used the 'hard way' it does require
    additional downloading of kernel-source and build tools.

    You might find it easier to configure the monitor at runlevel 3 (no GUI
    running), if you press ctrl+alt+F2 to get to a console, login as your
    user, then;

    Code:
    su -
    init 3
    <now you may need to press ctrl+alt+F2 if you get back to a login
    prompt>
    sax2
    Now grab the cdrom that came with monitor and then click on the monitor
    button, then press the 'utility disk' button. Now browse to the monitor
    inf file and upload. Test and exit sax2

    Code:
    init 5 && exit
    alt+ctrl+f2
    exit
    alt+ctl+F7
    The alt+ctrl+F7 is the GUI VT.

    Thanks for the detailed reply & instructions!

    The Gfx Card itself (i.e. both: Gfx Card-GeFore 8400GS & On-board Gfx-GeForce 7050/nVidia nForce 610i) is detected/configured ('easy method' from the link you pointed out)... problem is in configuring the Monitor, which is detected as just 'Monitor' in 'Hardware Info' panel of 'YAST Control Center'.

    Will try out what you have suggested. In the meantime (if it helps), pl have a look at the xorg.conf file (zipped URL in above previous post).

    PS:
    Don't think the LG CD that came with the Monitor has Linux drivers, it only has Windows drivers. But will check out all the folders, to be sure.

    Hope this is ok.

    Being new to Linux, is there a security risk in d/ling a zipped file or opening it (.conf file after unzipping) in gedit, on a Linux PC?
    I do not have any anti-virus software installed or Firewall enabled.

    Just out of curiosity & being new to Linux, is there a security risk in
    d/ling a zipped file or opening it -(.conf file after unzipping)- in
    gedit, on a Linux PC?

    Hi
    Much better, thanks :-) Yes, it is a security risk if you don't know
    where it's from :-)

    Your firewall is enabled, only need antivirus if you have a windows
    partition and don't want to pass on via emails etc. No viruses in the
    wild for linux, maybe a worm or two, but rootkits are a potential risk.
    It's a whole other subject on it's own probably in chit-chat or soapbox
    forums.

    So are you running this in a virtual machine? If not, I suggest you run
    the sax2 -r -m 0=nvidia command to clear out that xorg.conf

    See the nvidia link.

    If it's a virtual machine, you need to install the vmware tools on the
    guest system.

    I am not sure what you mean by the second part of the code (as quoted above) in your reply # 3 above. How can one access the CD-ROM from a CLI? Also, the '.inf' file on the CD would be for the Windows drivers?

    Here is a list of the files that are in the 'Drivers' folder of the CD-

    LG_Flatron_L177WSB Drivers List

    DRIVERS
    =======

    L177W.CAT
    L177W.ICM
    L177W.INF
    L177WSB.CAT
    L177WSB.ICM
    L177WSB.INF
    README.TXT
    How should I proceed?
    I do recall that after having first installed the nVidia driver ('easy way'- i.e. single-click on the link for new cards), I could access the Monitor & Display applet (if that is the right word) in the YAST Control Center & at that time it gave an option of selecting the LCD display from a list of manufacturers & Models as a sub-categ.

    So are you running this in a virtual machine?
    Sorry, overlooked this. No, it's not a VM...the Linux (ext3) partitions are on a separate HDD; Windows resides ona separate HD.

    Hi
    The command is either "su -" or "sudo -i" not "-s" (I think it only
    gives a shell) you need the root users environment which may be why
    you got the error.

    Try again as detailed (consider this the first warning :joking: )

    The have a look to see on the label if yours is the W or WSB model and
    that would be the one you select. They are just inf(ormation) files not
    OS specific about your monitor.

    The cdrom should be mounted and lives under the /media directory so you
    have no issues getting to it. Or you could copy those files to a temp
    directory on your machine.
