Thank you for taking the time to report this bug and helping to make Ubuntu better. Please attach your X server configuration file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.0.log) to the bug report as individual uncompressed file attachments using the "Attachment:" box below. Could you please also try to run without any /etc/X11/xorg.conf and let Xorg autodetect your display and video card? Please also attach the /var/log/Xorg.0.log from this attempt. Thanks in advance.
The screenshot you attached looks ok. There are no funky coloured horizontal lines. If you have a camera you can make a photo. Do you use a CRT or TFT? Did you tried to reduce the refresh rate?
