Hi unix25, thanks a lot. But, looks like your touchscreen chip is not Synaptics, I don't know if the solution apply to SiS' chip.
I got a new way to test. # cat /etc/modprobe.d/usbhid.conf options usbhid quirks=0x06cb:0x0af8:0x20000000 # sudo update-initramfs -u # sudo reboot Remember to correct the id, ex. options usbhid quirks=0x06cb:0x1d10:0x20000000 or options usbhid quirks=0x0457:0x1013:0x20000000 The quirk means do no send the init commands which may not supported by Synaptics, #define HID_QUIRK_NO_INIT_REPORTS 0x20000000 I need your ack to include the usb id into the quirk, thanks. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
