** Description changed: My laptop (Thinkpad X200T with multi-touch screen) installed the 'Trusty' ubuntu 14.04 (64bits), touchscreen works well after cold boot! But after suspend/resume, touchsreen do not response. Execute 'xsetwacom --list' in terminal, there is nothing, both 'wacom touch' and 'wacom stylus' are gone. I must logout and relogin or reboot, the touchscreen can be normal again. By the way, the same problem happens in the 'Saucy' ubuntu 13.10 (64bits). But in 'Raring' ubuntu 13.04 (64bits), this problem does no exist, touchscreen WORKS WELL after suspend/resume. This Thinkpad X200T updated the newest BIOS, and keep ubuntu OS up to date. Please fix this bug, because 14.04 is a very important version for touchscreen devices, and i think 'suspend/resume' function is important too.
