Hi,

   I have my monitor, keyboard and mouse shared through a KVM switch. 
One host is Linux Debian bookworm 12.5 and another is laptop running 
Windows 11. When I leave KVM on the laptop side for extended period I 
have issues switching back to Debian side. When I switch, the screen is 
blank and KB does not respond as if Debian is running headless. I had to 
remote login and reboot Debian side with KVM locked on this side to get 
back the monitor/KB. This happens regardless of whether I am in Xorg or 
VT.  I do not know how to force Debian/Linux to check for monitor/KB 
again after extended period of disconnect when it has assumed it is 
running headless. Any solutions?

Regards
Ramesh
