I found a workaround from https://answers.launchpad.net/ubuntu/+question/243145 that works with the X201 tablet, and it does not require rebooting, logging off and on again, or switching between virtual consoles. Try entering
sudo inputattach --daemon -w8001 /dev/ttyS4 If that does not work for you, then it is likely that the Wacom device is represented by a different device path (i.e. not /dev/ttyS4). Try executing sudo cat /proc/tty/driver/serial | grep 16550A which should output lines that look like the following: 4: uart:NS16550A port:00000200 irq:5 tx:19 rx:411732 RTS|DTR The grep command filters out the /proc/tty/driver/serial output so that only 16550A entries are shown (since the Wacom device is a 16550A serial device). The number 4 at the beginning of the line before the colon indicates that this line corresponds to TTY device #4, which is represented by /dev/ttyS4. So, for example, if the number was 1 instead of 4, you would enter /dev/ttyS1 in the inputattach command instead of /dev/ttyS4. If you see multiple lines in the filtered /proc/tty/driver/serial output, I would suggest going down the list until you find the correct device that reactivates the touchscreen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1275416 Title: touchscreen do not work after suspend/resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xinput/+bug/1275416/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
