Frequency out of range (Ubu 7.10 Wks)

    Having installed Ubuntu 7.10 workststion on several different machines (different hardware) I keep getting a strange common problem:
    During boot up (the graphical section as Ubu starts services with a progress bar, before the logon screen appears) I get the monitor reporting frequency out of range. This disappears when the log on screen appears and then desktop/apps operate perfectly.

    Is there a separate x configuration for the loading phase of boot up?
    Thanks for any advice.

    Are you using TFT displays or monitors? TFT monitors might try to adjust themselves during the boot process, which maybe causes the message.

    It's a TFT display. I think the message is up too long for the monitor to be adjusting itself. My feeling is that there must be some default X setting that applies during boot then gets set to a good value afterwards.

    Just so you don't think you're alone, mine does this too, using ubuntu ultimate edition( Gutsy G 7.10) NEC accusync lcd 52V. A little irritating to have to keep pushing reset button, isn't it? Hope someone has soultion

    Just a PS. it didn't do this on earlier versions, which were Fiesty Fawn based, just showed up with installation of Gutsy version(ultimate edition1.6) which indicates something in Gutsy causing problem

    My guess is that there is some default at this point - which some monitors like your Samsung can handle...?

    Hi deate,

    yes, that's what I wanted to see :)

    Please make a backup of your xorg.conf ...

    Code:
    cp /etc/X11/xorg.conf /etc/X11/xorg.conf.orig
    ... and afterwards edit the section "Monitor" in the xorg.conf. Add a line for horizontal synchronization and a line for vertical refresh. If your LCD is connected analog, the value for vert.refresh is 75.0 (Hz) - if it is connected digital, the value should be 60.0 (Hz). The value for the horiz.sync. depends on your device (have a look at the manual).

    The section should look like this (analog):

    ...

    Code:
    Section "Monitor"
    Identifier "LCD52V"
    Option "DPMS"
    HorizSync       30.0 - 75.0
    VertRefresh     75.0
    EndSection
    ...

    Or like this (digital):

    ...

    Code:
    Section "Monitor"
    Identifier "LCD52V"
    Option "DPMS"
    HorizSync       30.0 - 75.0
    VertRefresh     60.0
    EndSection
    ...

    Save the file, reboot your system and look what happens :)

    Best regards,

    Olli
