How to fix VirtualBox 6.0 theme

[pizzadude]

VirtualBox 6.0 doesn't like dark themes, so text is light grey on white, making it unreadable. To fix this without butchering our other Qt5 applications theme, create a file in /usr/local/bin/ call it "VirtualBox" without quotations, and put this inside:

Code: Select all

QT_STYLE_OVERRIDE=fusion /usr/bin/VirtualBox

Then just:

Code: Select all

sudo chmod +x /usr/local/bin/VirtualBox

All done!

Yep, the gtk2 theme looks bad in that release.

Just a note for those starting it via the menu/a launcher, a possibly simpler solution is to edit the launcher's properties and change the command from

Code: Select all

VirtualBox %U

to

Code: Select all

VirtualBox -style Fusion %U

For a list of available styles you can run the qt5ct command, if you have it. I agree Fusion looks best though.

Adding the VirtualBox file, as described above by the OP, also worked for me with Vbox 6.1.2 and Mint Cinnamon 19.3.
Thanks!
