20513,"Linux Mint ""white screen of death"" or initial black screen",wellitisspeedy,,"Runtime conditions:
- Macbook Pro with Mojave latest updates as a host
- Linux Mint latest as a guest
- Graphics adapter chosen - default VMSVGA

Issue 1 - initial total black screen in X11 mode:
Once the guest OS starts up in graphical environment with automatic login (I don't really need login screens for my VMs) and brings up Cinnamon, the whole desktop is black. Figured a workaround - switch between Full Screen mode and Windowed mode shows the desktop.
Note: This used to happen in all 6.0 and 6.1 versions. [[Image(https://altomaxtech.com/vboximages/TotalBlack.png)]]

Issue 2 - ""white screen of death"":
Once the workaround is applied, the desktop comes as completely white and the only visible area is the bottom panel. The while seems to be a top in the Z-order and all Windows are like under it.
I can only stop the VM by issuing poweroff from CLI or with the graphical interface only by pressing Enter as per the default choice to power off. [[Image(https://altomaxtech.com/vboximages/WhiteScreenOfDeath.png)]]

Workaround for both is to select VBoxVGA or VBoxSVGA adapters, but then I get a warning about 3D acceleration not going to be working.
