I still have problems with touchpad, please refer to my old post: maxamillion/fedora-openshift. There are some more details about my issue since I don’t want to duplicate the same info. My post was also merged with other guy’s, due to problem similarity. Other guy’s issue was fixed by a firmware upgrade, but mine still has it… And this is very very nervous when you can’t use your touchpad. I’m regularly looking for firmware updates and there are none related to my touchpad issue.
Now I found out that “after a while” is actually only when I connect my laptop to a power source. While my laptop is on batter I’ve no issues using the touchpad, but as soon as I connect it to a power source after a random time touchpad hangs and stops working, it can be immediately, or after 10 mins or even after a half-hour, sometimes it occurs when power is connected and I’m not touching touchpad at all, or while using it. This issue was introduced by Linux kernel 5.x and since then, it still actual. I don’t remember issues on 4.x kernel. An only restart helps to fix this issue, but even after reboot and power connected, the problem still comes in action as I described above.
Maybe this will help some experienced members here: Bug #1854798 “Synaptics s3203 touchpad not working after update ...” : Bugs : linux package : Ubuntu I think this is a very similar problem to mine.
Here are some more details about touchpad:
