An example of how to solve the failure of the touchpad in Ubuntu

Recently, I suddenly found that the touchpad in Ubuntu failed. I tried to find a method on the internet, change the driver, and change the code. As a result, the system collapsed. Later, I was told that I had restarted my computer again, but it was useless. Note: My fn + f7 is the function key for switching the touchpad. When the touchpad fails, no matter whether fn + f7 is enabled or disabled, my touchpad is useless. What should I do? There is really no good solution, so I am in a bad mood to press fn + f7 over and over again, so I accidentally found a fine

Recently, I suddenly found that the touchpad in Ubuntu failed. I tried to find a method on the internet, change the driver, and change the code. As a result, the system collapsed.

Later, I was told that I had restarted my computer again, but it was useless. Note: My fn + f7 is the function key for switching the touchpad. When the touchpad fails, no matter whether fn + f7 is enabled or disabled, my touchpad is useless.

What should I do? There is really no good solution, so I am in a bad mood to press fn + f7 over and over again, so I accidentally found a detail, the touchpad display is enabled when I press it for the first time. As we all know, the general laptop boot touchpad should be enabled. If you press fn + f7 to display the enabled status, it indicates that it was previously disabled, in other words, when my notebook is started, the touchpad function key "fn + f7" is disabled. The last time I used a computer, I shut down the touchpad. Is there a problem in this place? So I restarted the fn + f7 when it was enabled (the touchpad didn't work at this time) and it was enough to work after the restart. That is to say, if fn + f7 is disabled before shutdown, the touchpad may fail if it is restarted or restarted after a long time.

Of course, this method is only successful in my notebook, and does not necessarily work for all laptops. If you have any questions, try it and solve the problem.
