Ubuntu screen flickering and shift problems

My notebook is Lenovo yunci. After updating Ubuntu11.10, I found that the screen is flickering and moving. It is actually a problem with the graphics card driver. The driver provided by the N card official website is not easy to use. Try to use the Bumblebee for reference: Ghost.

Flash Problem Solving

To solve this problem, you can use the following method.

Terminal execution: xinput list

You will find two Video buses. Remember the second ID. the ID of my second Vedio Bus is 8.

Then the terminal executes: xinput set-prop 8 "Device Enabled" 0

However, after the computer is restarted, the command becomes invalid. Therefore, you can add the command to. bashrc to execute the command during logon. At this point, the problem of frequent and irregular flash screen disappears.
