I have recently installed Clear Linux on my laptop. My device is Acer aspire E5-511. There is a problem with keyboard and touchpad. Both of them are not working. However, in the Boot Menu of my device, keyboard is working well. Before installing Clear Linux, I used Ubuntu version 18.04. At first, They worked very well, but after getting some updates, keyboard stopped from working. Then, I thought if I had changed my laptop’s system, the problem would have been solved. However, I have a same problem now. So, How can I solve this issue? I look forward to your response.
