Check your bootloader and make sure there is no errant argument being sent during boot?

Hello,
My recent Debian install on a HP 840 EliteBook G1 is booting up upside down.  Anyone know how to fix this?
  This happened before with Debian 11 and I found a command that fixed it permanently.  This is what I found yesterday:




xrandr -o normal
That command will get me by that session, but if I reboot and login again the splash screen and login in screen can and will be upside down.
I had to add the sources.list part for the wifi card in using vi and upside down.  Try that sometime.

SSD will not matter.
thanks,
Greg
