They are not really possible for galaxy devices due to the locked down bootloader

There is likely a way to permanently enable this input method. But I'm disinterest now and am sadly gonna have to send you off on your own. I could still look through the log if you'd like.
Nono you don't understand. Graphene OS comes default without any version of google play services, neither the original one or the microg alternative. You can enable sandboxed google play for compatability, here it is pure preference if you prefer sandboxed google play or microg. I am not sure what I prefer yet. So the most degoogled way is actually no google api calls at all. Which I do think might be available with microg by disabling it? I forgot.
Might wanna fix that
Best he can do is install non microg roms completely removing google from his system, but microg is a nice compromise.
Start the VM from full normal shutdown, not save-state. Run until you see the problem happen, maybe provoke it by trying to change the mouse click speed, then shut down the VM from within the VM's OS.
Right-click the VM in the main Virtualbox window's VM list, choose Show Log. Save the far left tab's log and the hardening log next to it, zip them, and paste them in some online pasting service or what have you.
Try using the PS/2 mouse in the VM's Pointing Device settings. These settings should also provide you with other useful options.
If you call it forward security I think you should ask yourself if the dude who swapped names is maybe more correct as he has the right jargon ;)
Okay, searching for a few things I can think of. Until I find somthing, a few more questions. Does changing the click speed do anything, if barely noticeable as the difference is negligible or does it do absolutely nothing? Also, if you were to install another guest os please try Windows. I have a nasty suspicion that Windows may have bad support for Virtualbox running non Windows machines. Are you sure that your processor supports virtualization? Might you provide me with a log file?
Alright we're getting somewhere. Have you tried another virtualization method instead of Virtualbox? Is your software up to date? What are your system specifications? By Linux VM do you mean a VM specifically running in Virtualbox on Windows? Which Linux VM? Does this affect all Distributions that you may use?
Well TNT... it's dynamite
Hmm. Is this application specific?
Why should I realise that and why does it matter?
