Using wireshark to monitor the usb traffic, we'll find the touchscreen becomes abnormal after systems sends the IDLE command to it. But the touchscreen could revive after sending some other commands, such as GET_DESCRIPTOR.
I'll build a test driver soon, but I need to build a list for the affected usb id. On this bug, there are 2 IDs 06cb:1d10 and mine is 06cb:0af8 Please reply if your borken touchscreen ID is not listed above. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1180881 Title: Touchscreen only works after suspend/resume on Lenovo ideapad P400 Touch To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/+bug/1180881/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
