Eclipse setting
If pdflatex escape is not found, then probably old texclipse version. Delete the old one
https://stackoverflow.com/questions/892203/how-do-i-delete-an-eclipse-perspective-for-a-plugin-i-uninstalled (by going to update and there there is a button that says "whats installed")
Install texclipse form the Marketplace plugin (2+ version number) -- that one has the properties to put --shell-escape
https://www.davidpace.de/category/latex/texlipse/
Open Preferences -> Texlipse -> Builder Settings, select the PdfLatex program and click Edit. The following dialog appears, in which you can add the -shell-escape option to the command line:

Mouse setting:
This worked for me:
xinput --set-prop 11 294 1
where:
11: is my mouse id, you should find and replace with yours
xinput --list --short
294: is the "Accel Speed" property id of my mouse. Just change 11 with your id and you can find your desired prop id with
xinput --list-props 11
1: the final number is the property value. For me default was 0, 1 accelerated the pointer up.
You can add the first command to the startup applications to keep the settings after a reboot. Instead of the device and prop id you can quote them in case they change after a reboot, ex:
xinput --set-prop 'Microsoft Basic Optical Mouse' 'libinput Accel Speed' 1
