We changed the model of touch screen from old:

Bus 001 Device 003: ID 0eef:c000 D-WAV Scientific Co., Ltd 

⎡ Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ eGalax Inc. eGalaxTouch EXC3188-4642-08.00.00.00  id=6    [slave  pointer  (2)]
⎜   ↳ eGalax Inc. eGalaxTouch EXC3188-4642-08.00.00.00 UNKNOWN  id=7    [slave  pointer  (2)]
⎣ Virtual core keyboard                         id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]

to:

Bus 001 Device 003: ID 0eef:c002 D-WAV Scientific Co., Ltd

Now, we have the problem that touch screen suddenly stops responding to touch events and the issue is resolved if the monitor is turned on/off. I would like for some help on how to even start debugging this. Any other needed information will be added.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
