Locked bios doesn’t mean anything if they have physical access to your PC.
They can reset the bios with a jumper, replace your bootloader, forensically image your hard drives and wait for you to boot and unlock your drives so they can grab the keys from memory.
A second trip could install a rootkit/malware because they know your encryption keys.




There was an issue with the Steam overlay that happened when they added the screen recording feature. After about 25 minutes any input will cause a delay in rendering the current frame.
You can disable the overlay or add LD_PRELOAD=“” to your launch options, if this is the problem
Flameshot is pretty good too
Try booting with the non-secure boot option then
1 means secure boot is enabled, 0 means disabled.
If it’s 0 then you could use any distro, regardless of secure boot support.
