There is a feature of NetBeans where it puts a red line as the right margin in the code editor. By default this margin is at 80 characters but I prefer it at 99 characters. To change the setting in NetBeans see Tools -> Options -> Editor -> Formatting -> All Languages -> Tabs And Indents -> Right Margin. For example:
See my reference configuration for hardware selections which worked well for me when running Kubuntu 18.04 guests on Kubuntu 18.04 hosts.
After configuring your VM you might like to read about installing Kubuntu on it.
So basically I want to run KDE Plasma under Ubuntu and this can be called Kubuntu.
This article is a little bit cargo-clutish. I.e. “I did this and it seemed to work.” and “I don’t do this because it didn’t seem to work.”
I have a pretty heavy reliance on Salt Stack for system configuration. My salt config is all built around Ubuntu 18.04 LTS.
When I need to install a Kubuntu desktop, this is how I do it:
Note that if your Kubuntu install is a VirtualBox guest you need to start it with a normal start if you want the shared clipboard to work. If you start headless or detachable the shared clipboard will not work (in my experience).
If your Kubuntu install is not a VirtualBox guest you can skip the virtualbox-guest-* package installation above.
My shared clipboard wasn’t working for my Ubuntu 18.04 guests running on my Ubutnu 18.04 host under VirtualBox 6.0.
To fix first make sure that the shared clipboard is enabled in VirtualBox for the VM. The setting for that is under General -> Advanced -> Shared Clipboard.
Then try running these commands in the guest:
These steps (or something similar) got the shared clipboard working for me. Hooray!
Note that these instructions will vary if you’re running a HWE kernel.
