    Green dots on screen 12.04 (not hardware)

    I tried searching for a similar issue, but couldn't find anything for my exact problem. I am running Ubuntu 12.04 32-bit, and I have a series of green vertical dots across my screen. I see the dots even when I VNC into the system, and in screenshots, so I know it's not hardware. Does anyone have any ideas?

    I only see a black screen shot.

    Please run

    I have also attached a screen shot from the VNC connection on my phone.

    Re: Green dots on screen 12.04 (not hardware)

    I just viewed both attachments on my Windows system, and you're right the dots do not appear. If you actually zoom in on the image, you can see grey dots though. I don't know if they are being lost over the web or what, but I know they're there in both VNC and hardware.

    The forum is converting my png to a jpg which is where the loss occurs. Here is the original image

    Re: Green dots on screen 12.04 (not hardware)

    That is a very old gfx card. I don't know if there is anything you can do besides upgrade your gfx card, or down grade to a older Ubuntu release.
    Please someone correct me if I'm mistaken.
    Cheers!

    No, you're correct. The card is too weak (how could I miss that?)

    Don't install old releases, but Lubuntu 12.10 is a good option.

    Re: Green dots on screen 12.04 (not hardware)

    Does the graphics card explain the green dots over VNC as well?

    Re: Green dots on screen 12.04 (not hardware)

    I don't know, but it's easy to find out Try Lubuntu 12.10 with only open-source drivers.

    Googling seems to indicate that these dots have been around for some time and that there might be more than one reason. I guess some more experimenting is needed.
