As I can reproduce this problem on a standard tty device without X (see below) I am suspecting a driver problem, but I might as well be wrong. The device in question is the Touchscreen of a Dell Inspron Duo convertable, a USB device with id 0eef:725e (D-WAV Scientific Co., Ltd), found and registered as an input device by the kernel as [ 6.931638] usb 4-1: Manufacturer: eGalax Inc. [ 16.186272] input: eGalax Inc. USB TouchController as /devices/pci0000:00/0000:00:1d.2/usb4/4-1/4-1:1.0/input/input10 [ 16.187162] hid-multitouch 0003:0EEF:725E.0001: input,hiddev0,hidraw0: USB HID v2.10 Pointer [eGalax Inc. USB TouchController] on usb-0000:00:1d.2-1/input0 I have tested the behaviour with and without X11. Without X11 I was using a standard tty and using cat on the input device. After boot the input device gives lot of output while touching the screen, after resume the device stays silent. I have this problem since moving to hid-multitouch for handling this device. I will be happy to test and supply more information. Thanks a lot for looking into this, Jan-Matthias Braun PS: As I am not subscribed to the mailing list, please CC me.
