T410s with white stripesMy dual monitor settings worked perfectly fine until just recently. Now the resolution on the second monitor is very low and it shows white vertical stripes. I am using Ubuntu 12.04 with GNOME 3.4. I am using a docking station for my Thinkpad T410s, that is how the Laptop is connected. The main monitor (which works well) is connected via DVI. The laptop monitor works well wenn not attached to the dual screen system. If I turn off the main monitor via software, the laptop monitor still shows white stripes.

Here is my xrandr -q:

If enable dual head mode (two X screens), the second monitor went white after login with unity or unity-2d. After tracking the gnome-session, it is caused by running "nautilus -n" for this configuration. And if kill the nautilus process, the desktop showed up normally on second screen. It is a Bug. Try using Ubuntu 13.10.

It sounds like the LCD panel OR the video card are bad, or it could just be a bad driver. Head to the manufacturer's website, download, install and reboot.

Below are some thing to check:

  • Try connecting to an external monitor, if the line appears on the external monitor, the issue is a bad video card. If the issue does NOT appear on the external monitor, the issue is the LCD panel.
  • It might be a simple fix like a loose connection to your laptop display.
  • Could be the cable on the hinge side that is getting worn.

I suggest to change refresh rate (mainly decrease it) which seems to be the real problem. For instance check this question to see how to change the refresh rate

Try different refresh rate until you got the optimal vision. And for your screen I think it's enough a 1366x768 resolution with a refresh rate of 60

xrandr -s 1360x768 -r 60

The timings are wrong for the laptop display. That looks an awful lot like what happens when it's trying to use the same resolution on two monitors, but one of the monitors is not capable of that resolution.

Try decreasing (or just changing) the resolution on the laptop monitor.
