Find directories of certain (744) permissions and change them to 755




For some reason some directories are set to 744 permission from when saved from some systems. 

They need to be 755 for the system to properly back them up.

This will change the permissions with a chmod after showing them.
find . -type d -perm 744 -print -exec ls -ld {} \;

find . -type d -perm 744 -exec chmod 755 {} \;

Nice page of examples of chmod is here

setting python version on Ubuntu




Adapted from this link

https://unix.stackexchange.com/questions/410579/change-the-python3-default-version-in-ubuntu


 sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.5 1

annoying note #1.  Pip install is fskced up on Ubuntu.  It installs a wrapper for python-pip, but doesn't install the underlying python 3 main version.

so do this:

sudo apt-get -y install python3-pip

if ubuntu unattended upgrade is running, kill it by editing

/etc/apt/apt.conf.d/10periodic
APT::Periodic::Update-Package-Lists "1";
 
change the 1 to 0, and reboot (easiest).  If update is in progress
killing the scripts is a big PITA.

if you have to remove pip to start over use:
sudo apt-get purge python-pip

upgrade pip with

pip3 install --user --upgrade pip

Microsoft Mouse setting in Windows 10, plus Dell (or other) mouse driver controls


Windows 10 update to 1903 Build 18362.267 (or so) lost the setting to disable the touch pad when a mouse is plugged in.

I don't know why this isn't front and center in the  main Windows settings, but it isn't. 

If a touch pad is active, finger gestures above it will cause unwanted selections at times, and motion of the cursor.  If one turns off the pad completely, one would have to use keyboard actions to navigate back to the mouse / pad enable / disable when a mouse is unplugged.

The dell dialog has a setting to allow disabling the pad when a mouse is plugged in, and that is very desirable to have, as one only need to pull the mouse, or more important if you don't have the mouse, but a wireless mouse dongle is plugged in, you just pull it and have the pad working.

So making that setting persist is important.  Win10 upgrade didn't do that.

Recording how to get back to it in the current release.

Navigate to the Mouse settings.  (hit windows button, type mouse settings)




Select Additional Mouse options in the above.  This pops up.



select "click to change Dell Touchscreen settings":
