I dug around a bit, and found that the touchscreen can also be fixed by reloading the ic2_hid module.
It also works to reinitialize just the hid driver for the touchscreen (rather than reloading the entire module) by running: echo 0018:06CB:77B2.000C > /sys/bus/hid/drivers/hid-multitouch/unbind echo 0018:06CB:77B2.000C > /sys/bus/hid/drivers/hid-multitouch/bind Disabling and re-enabling the device with xinput does *not* work. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xinput in Ubuntu. https://bugs.launchpad.net/bugs/1796580 Title: Touchscreen breaks after suspend on Acer Aspire Switch 11 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xinput/+bug/1796580/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
