Thanks for the bug report. Your kernel log mentions some errors regarding what looks like a Synaptics touchpad:
[ 5.550275] i2c_hid i2c-SYNA3602:00: i2c-SYNA3602:00 supply vdd not found, using dummy regulator [ 5.550304] i2c_hid i2c-SYNA3602:00: Linked as a consumer to regulator.0 [ 5.550306] i2c_hid i2c-SYNA3602:00: i2c-SYNA3602:00 supply vddl not found, using dummy regulator [ 5.568184] i2c_hid i2c-SYNA3602:00: unexpected HID descriptor bcdVersion (0x0000) So this sounds like a kernel bug, or a BIOS or hardware problem. ** Summary changed: - Touchpad and touchsrceen not working + TREKSTOR Primebook C11B touchpad and touchscreen not working ** Package changed: xorg (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1850681 Title: TREKSTOR Primebook C11B touchpad and touchscreen not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1850681/+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
