xrandr --off: reboots system instead of disabling display

I'm trying to disable the display of my laptop with the following cli:

`
xrandr --output LVDS-1 --off

` The display immediately disables but then the laptop **REBOOTS** sometime after 0~600 seconds. I've tried some debug, but no success so far: - External display works fine. ie: properly disabled by xrandr --output HDMI-1 --off and no system reboot. - journalctl is posted bellow, but I could not decipher it. - HandleLidSwitch=ignore and others makes no difference. Any idea what might be happening? ----------------------- ### Additional Info ### - **Notebook:** Gateway NE56R - **CPU:** Intel Pentium 2020M - **Operating System:** Debian GNU/Linux 12.8 ### Debug: External Display ### I've plugged an external HDMI display and run:

`
xrandr --output HDMI-1 --off

` Everything seems to work fine. Ie: the display immediately was disabled and the laptop did not rebooted. ### Debug: journalctl ##### Most of the time I see nothing unusual at journalctl. However, sometimes I get the following log after the xrandr:

` Unfortunately, IDK whether this log is an issue or not. ### Debug: HandleLidSwitch and others ### I've also modified /etc/systemd/logind.conf and changed the HandleLidSwitch line to HandleLidSwitch=ignore. Similar to several other lines:

HandlePowerKey=ignore
HandlePowerKeyLongPress=ignore
HandleRebootKey=ignore
HandleRebootKeyLongPress=ignore
HandleSuspendKey=ignore
HandleSuspendKeyLongPress=ignore
HandleHibernateKey=ignore
HandleHibernateKeyLongPress=ignore
HandleLidSwitch=ignore
HandleLidSwitchExternalPower=ignore
HandleLidSwitchDocked=ignore

Unfortunately, nothing happened (ie: system still reboots after xrandr).
