MacOs Cannot install drivers for tone studio

The installation guides are gibberish. While installing the driver, I'm asked to remove the driver ... and go to security and give permission [to WHAT, and WHERE]. Hopeless instructions here. Dropped the program after 10 - 15 attempts. That's enough. 

Linux / Unix: rsync vs. dd

  • dd will create one file image
  • rsync will copy file  for file
  • dd is faster
  • rsync will give you easy access to the files in the backup

Ubuntu 21.04 Brightness GUI


Ubuntu 21.04 has no GUI for the screen brightness. Add  this repo:

# sudo add-apt-repository ppa:apandada1/brightness-controller
# sudo apt install brightness-controller

Now you can run the program, or add it to favorites.

Ubuntu 21.04 set brightness

There is no brightness button in Ubuntu 20.04. Why? But you can set the brightness via terminal commands.

Step one: find the name of your monitor.

In my case:

# xrandr | grep " connected" | cut -f1 -d " "
# HDMI-2

Then set the brightness in the terminal:

# xrandr --output HDMI-2 --brightness 1

Night settings could be a brightness of e.g. .75

No GUI for the screen settings, such as color and brightness etc. is yet another serious UX-flaw in the problematic Ubuntu 20.04. This update is not the best we saw from Ubuntu. We need UX'ers in Ubuntu.

[SOLVED] Ubuntu 21.04: if Share Screen in Zoom does not work

  1.  Log out of the session.
  2. On the log on screen click the gear at the bottom.
  3. No you can choose between the new Wayland and another option.
  4. Don't chose Wayland. Choose the old version.
It seems that Wayland is not ready for Zoom yet. I hope that you see this before trying to share Zoom screeens in Ubuntu 20.04 ;-)

Ubuntu: Connecting Gnome Files to MacOS via SFTP

 



So the connection via SSH from Ubuntu to MacOS was possible. Why not establish a GUI-connection via Files. You can add other network shares at the + at the bottom of the shortcut list.

In the form add the address of the remote computer and use a sftp connection:

sftp://192.168.xxx.xxx (use the actual ip-adress where you see the xxx)

Click ok.

And that's all it takes.


Now you can work with the files on your Mac from Ubuntu.

Nice!

Update Ubuntu to the latest version


 

Here is a crash version:

# sudo apt update
# sudo apt upgrade
# sudo apt dist-upgrade
# sudo apt autoremove

Edit this file: /etc/update-manager/release-upgrades

Make sure, that the Prompt is set to normal.

# sudo do-release-upgrade

or if you dare and want the upgrade before the actual release:

# sudo do-release-upgrade -d

Mainly based on this blog post.
