I have this weird issue with my monitor. How can I fix it?

  • 772

I have been experiencing a few problem with my monitor HP TS-19SV even with the newly released Ubuntu 12.04 (although, this had happened before on Ubuntu 11.10, 11.04, 10.10 and 10.04. Basically, from time to time, when I start my computer and got to the Ubuntu's desktop, I see quite a bit of black lines next to my cursor and when I move the cursor up to the limit of the screen, the desktop fills with those weird lines. Something similar happens when a move the cursor at the bottom of the screen. Obviously, an image will be more helpful than my attempt of description:

Look at that rectangle next to my cursor:

When I reach the bottom of the screen:

When I reach the top of the screen:

Has anyone experienced something similar to this?. How can I solve it?.

Thanks a lot

UPDATE:

After running sudo lshw -C video I get this:

UPDATE II: The answer given by Luis Alvarado solved this issue. There is still a weird fading effect when I shut down / Log out that happens when there is a process waiting to be closed but for the most part, everything is working great.

    Looking at this part of your question: P4M890 [S3 UniChrome Pro] I noticed you had a video card that is in the group of the OpenChrome drivers. There is some good news and bad news. The Bad news is that it has many graphic related issues. you can see several of them (Most for the 3D graphics part) here: https://help.ubuntu.com/community/OpenChrome

    The good news are the following:

    On the same link provided above: https://help.ubuntu.com/community/OpenChrome you can see that there is a compiling from source workaround that "probably" could work for the 3D part.

    There is also some workaround fixed to disable 3D altogether. By editing the xorg.conf: and adding the following:

    Section "Module"
        Disable    "dri"
EndSection

    (there are a couple of more xorg.conf edits in the link provided)

    There is also a ticket system for bugs detected: http://www.openchrome.org/trac/report/1

    (Some of the tickets have ideas and comments about how to fix some of the problems)

    Lastly, if not downloaded already (It should be downloaded since it is done by default), download the xserver-xorg-video-openchrome package. And tell xorg.conf to use the following driver in the Device Section:

    Driver "openchrome"

    One final note, some links point to downloading the proprietary VIA driver for this from here: http://linux.via.com.tw/support/downloadFiles.action for what I could see it is very abandonware since the only one I found there was the 9.04 version driver.

    Anyway you have several options that might help, others that might help and a little bit more complicated and the last ones which are just to eliminate 3D completely.

    If the file xorg.conf is not found, you can created by doing the following:

    1. Boot the system in Recovery Mode. You can do this by pressing ESC or leaving the SHIFT key pressed until the GRUB menu appears. Select Recovery Mode (Should be second option).

    2. After booting go to the terminal as root. There is an option that tells you if you want to log in the terminal.

    3. Type X -configure. The X is in upper case. This will create the file xorg.conf.new in your current home directory.

    4. Test to see if the file is working by doing this X -config xorg.conf.new. If a gui environment appears and looks good then you can do the following step. If not, I suggest editing the xorg file and changing anything you need until it looks good. You can edit with nano: nano xorg.conf.net doing any modifications and save by pressing CTRL+X and pressing Y to save and quit.

    5. Copy the new xorg file: cp xorg.conf.new /etc/X11/xorg.conf

    6. type exit or reboot to test it out.
