IPTS driver fails to find device after resume. #667

Open kylerlaird opened 4 years ago

kylerlaird commented 4 years ago

I'm using 5.8.3-surface on a SP7. The touch screen is inaccessible after resuming from suspend. I've tried restarting iptsd.service and reloading the ipts module. Access to /dev/ipts still yields "No such device".

Just now discovered this. Ubuntu 20.04 on an older Surface Pro (unsure what model, was a free gift).
Can't enable service after logout or suspend. Must reboot to reactivate service. Currently have it set to load on boot from; sudo systemctl enable lpstd.service
