I'm fairly inexperienced with Linux in general and I recently installed Ubuntu 22.10 on my Acer Aspire (model number is E5-774G-52W1). I am having an issue where the touchpad will work for a few minutes and then it will suddenly stop working. When it is in the state that it does not work, it will just do an action of left clicking several times when I try to move the pointer around.
When I run the command xinput -list I see the following:
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ ELAN0501:00 04F3:3019 Mouse id=14 [slave pointer (2)]
⎜ ↳ ETPS/2 Elantech Touchpad id=17 [slave pointer (2)]
⎜ ↳ Holtek USB Gaming Mouse id=11 [slave pointer (2)]
⎜ ↳ ELAN0501:00 04F3:3019 Touchpad id=15 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Video Bus id=8 [slave keyboard (3)]
↳ Sleep Button id=10 [slave keyboard (3)]
↳ HD WebCam: HD WebCam id=13 [slave keyboard (3)]
↳ Acer WMI hotkeys id=18 [slave keyboard (3)]
↳ Holtek USB Gaming Mouse id=12 [slave keyboard (3)]
↳ Holtek USB Gaming Mouse id=19 [slave keyboard (3)]
↳ Power Button id=9 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=16 [slave keyboard (3)]
I have a mouse plugged in as well, so pay no mind to the gaming mouse entries. I only plugged this in as a response to the issues I'm having.
Additionally, I have run xinput --list-props 15 and xinput --list-props 17 both twice. Once when the touchpad was working and once when the touchpad stopped working about an hour latter. I compared each property before and after and there was no difference.
I suspect I might have an issue with the driver, but I am needing some help verifying exactly what the issue might be. I have verified that the touchpad is enabled in the settings. I have verified that the mousepad lock is not enabled. I have rebooted several times and each time, it will work at first, then will stop working as previously described.
Please let me know if any of you have any ideas, or if you would like me to post any more information. I was able to find a helpful debugging touchpad post on an Ubuntu wiki, but I couldn't find a fix there that worked for me.
UPDATE
I found a recommendation to try running sudo rmmod psmouse and sudo modprobe psmouse proto=imps. When I run the second line I get the following error message.
libkmod: ERROR ../libkmod/libkmod-config.c:712 kmod_config_parse: /etc/modprobe.d/psmouse.conf line 1: ignoring bad line starting with 'elantech_smbus=0'
If anybody has any ideas fix this or further troubleshoot, please let me know. If I find any solution, I will post it here as well.
