Going from VirtualBox 6 to version 7 I noticed the theme went from light to dark, so I thought there was a theme setting. I searched and could not find a theme setting.

I Google’d and found this provided by the Google Artificial Intelligence (AI):
In VirtualBox 7.1, theme customization, especially for dark mode, is platform-dependent: on Windows hosts, you can force dark mode through VirtualBox preferences, while on Linux and macOS, VirtualBox follows the system’s look and feel.
Here’s a more detailed explanation:
Windows Hosts: You can force a dark theme in VirtualBox 7.1 on Windows hosts by going to VirtualBox Preferences and enabling the dark mode option.

Linux Hosts: VirtualBox 7.1 on Linux follows the system’s theme, and it’s difficult to force a specific theme due to the variety of desktop environments and window managers.

macOS Hosts: VirtualBox on macOS also follows the system’s theme, making it easy to switch between light and dark modes.

Qt6 and GTK2: VirtualBox 7.1 is built on Qt6, which doesn’t have official support for GTK2 themes anymore, but VirtualBox integrates an old GTK2 support plugin for Linux, which requires exporting the environment variable QT_QPA_PLATFORMTHEME=gtk2.

My current Ubuntu theme setting is dark mode:

I hope this save someone time in a wild goose chase. All the examples I found were of users demonstrating VirtualBox 7 on the Windows OS.

When making changes to the VM, best to have the VM off. Make the changes and boot the VM.

This took me hours to figure out, with most of the time used searching and with no avail. So I started to experiment and found the answer.

In the Proxmox PVE VM, go to Hardware and make sure that Display is set to SPICE (qxl):

This will activate the audio in Windows 11.

Even though the audio is activated on Windows 11, unless the Audio output mode is set to Local on the RDP client, Windows will shows no audio.

Sometimes I wake up and say to myself, “Today is the day that I will make changes to my life and will continue to make changes until I have reached that place where I vision myself to be.” I go to work and then when I am done, I am tired, I sit on the couch, watch television, eat dinner and sleep. POOF! The day is gone and I wake up the next day finding myself doing the same thing all over again.

I have found myself…

Last year I left a position, that seemed to me, I was becoming stagant, so I applied for several positions and was able to accept a position that I deemed challeging. The last few days, I found myself again in that situation as my previous position, so I decided to make a change, not in work position, but with myself.

I do now know where I read, that to make a change, as a human, I cannot make large changes that will be life altering. I might be able to do large (abrupt) changes for a day, maybe a week or a month, e.g., diet, exercise, etc., but abrupt changes are not sustainable in the log run and I will revert back to my old routine. So the best to make the changes incremental and small, or even tiny. Try thrity-second changes. Do something that I want to change for thrity-seconds, once I start, see if I continue after the thrity-seconds has completed. This has made a change in my life, hence why I am documenting this. I will continue to make this change until I have reached goals that I have set for myself.

My hope that by December 31th, I can make that leap that I have been thinking of for a while…
