    11.04 - Input not supported!

    11.04 LiveCD works just fine.

    Installed to HDD but won't boot. I don't even get the grub boot menu. All I'm getting is "Input not supported" floating across my screen. Anyone know how to fix this?

    Thanks for that but as I'm not getting the grub boot menu, I'm unable to get into the OS to do any tinkering.

    I am having the same problem after upgrade to 11.04. I cannot set the values in Grub because my monitor needs to be working. I don't have a second monitor. This problems seems like a need a second monitor to enable to me to change the settings. I am using a Acer 22 " monitor.

    IIRC, that's known to happen with Lenny, with the Acer X193W. (apparently, because the X.Org that ships with Lenny, falsely assumes it supports a res higher than 1440x900 and seemed that X.Org tried to use 1600x1200 or about that!) I had to connect a CRT to use Lenny!

    But, Ubuntu, especially Natty Narwhal, shouldn't be trying to use too high of a resolution!
    Because X.Org was updated.

    Re: 11.04 - Input not supported!

    That's interesting because I'm using an Acer P193W 19" LCD monitor but I've never had this problem with any other distro I've ever installed. Bearing that in mind and the fact that there's no /etc/X11/xorg.conf in 11.04, I conclude that the problem's with Ubuntu and not with my monitor. I've managed to get into my Ubuntu partition from another distro and, following a comment I read in another thread, I've un-commented #GRUB-GFXMODE=640X480 in /etc/default/grub and then run update-grub but it compalins about not being able to find something and exits. Still can't boot 11.04!

    Re: 11.04 - Input not supported!

    you need to create a custom xorg.conf

    Section "Device"
    Identifier "Configured Video Device"
    Driver "nvidia"
    Option "ConnectToAcpid" "off"
    Option "NoLogo" "False"
    EndSection



    Section "Monitor"
    Identifier "Configured Monitor"
    # add these custom lines with the monitor doc values to workaround boot issue
    HorizSync 31.0 - 48.0
    VertRefresh 56.0 - 65.0
    Gamma 1
    # adapt these values depending on your monitor
    EndSection

    # Section "ServerFlags"
    # Option "ignoreABI" "true"
    # EndSection

    Section "Screen"
    Identifier "Default Screen"
    Monitor "Configured Monitor"
    Device "Configured Video Device"
    EndSection

    Re: 11.04 - Input not supported!

    I made a backup copy of my xorg.conf and overwrite it with the following. But the problem persists. I have a Acer P221w. Also I am doing an upgrade to 11.04

    Section "Device"
    Identifier "Configured Video Device"
    Driver "nvidia"
    Option "ConnectToAcpid" "off"
    Option "NoLogo" "False"
    EndSection



    Section "Monitor"
    Identifier "Configured Monitor"
    # add these custom lines with the monitor doc values to workaround boot issue
    HorizSync 30.0 - 82.0
    VertRefresh 56.0 - 60.0
    Gamma 1
    # adapt these values depending on your monitor
    EndSection

    # Section "ServerFlags"
    # Option "ignoreABI" "true"
    # EndSection

    Section "Screen"
    Identifier "Default Screen"
    Monitor "Configured Monitor"
    Device "Configured Video Device"
    EndSection

    I tried it too but the problem was still there.

    However, I've now found the solution here which works for me.

    Re: 11.04 - Input not supported!

    I'm having the same problem, fresh install, new hard drive. Error occurs with multiple monitors. No grub menu is displayed, even if I increase the timeout in /etc/default/grub. Boots fine off of CD. If I'm fast, I can use the arrow down followed by enter, but that doesn't resolve the issue.

    Re: The solution earlier in this thread about a custom xorg.conf, is that just for the Acer or for ayone experience this?
