Are you using a touchpad frequently during the day? Then please read on, I need
some touchpad usage data and it'll only take you 5 minutes to run the commands
below to gather the data.
If you're technical enough, here's the TLDR:
in screen, run sudo evemu-record > touchpad-recording.evemu, select your
touchpad device and at the end of the day upload a compressed tarball somewhere
and send me the link off-list. thanks.
Otherwise, the steps one-by-one:
Open a a terminal now, then install evemu:
$> sudo dnf install -y evemu screen
Then start screen:
$> screen -S evemu
Now you're inside screen and you can start the recording
$> sudo evemu-record > $HOME/touchpad-recording.evemu
One device will be a touchpad, named "SynPS/2 Synaptics Touchpad" or some other
name that should be identifiable. If you're on a late model Dell, it may be
named DLL0234 or something. Once you selected the device, evemu will start
Then hit Ctrl+a, then d to detach screen and return to the terminal.
Check that the recording works:
$> tail -f $HOME/touchpad-recording.evemu
Whenever you touch the touchpad, you should see events filling up the screen
now. If so, everything is working. Hit Ctrl+C to quit the 'tail' command. You
can close the terminal now.
The screen session will now sit in the background, recording all your touchpad
events into that file. At the end of the day:
First, open a terminal and restore the screen session:
$> screen -r evemu
Hit Ctrl+C to interrupt the evemu-record process, then type exit to quit
screen. Compress it first so it reduces in size a bit:
$> gzip $HOME/touchpad-recording.evemu
Now upload the newly created $HOME/touchpad-recording.evemu.gz file somewhere
and send me a off-list email with the link so I can grab it.
As for "why" do I need this? I need it to analyse touchpad motion data to get
an idea of what range of finger motion speed is common and expected during
