  * Timing cached reads:   7618 MB in  2.00 seconds = 3816.76 MB/sec
  * Timing buffered disk reads: 1394 MB in  3.00 seconds = 464.49 MB/sec
* /dev/sdb:
  * Timing cached reads:   8574 MB in  2.00 seconds = 4297.24 MB/sec
  * Timing buffered disk reads:  52 MB in  3.04 seconds =  17.12 MB/sec

  MatchIsTouchpad "on"
  Driver "libinput"

Tmp fix:

### Disable bluetooth

```shell

At this moment, no fix.
