Description Jeff Joshua Rollin 2020-10-10 22:12:14 UTC

I'm running FreeBSD 12.2-RC2 with lightdm and XFCE on a ThinkPad E550 with 12GB RAM and a 1TB SSD. After a few minutes of inactivity, X11 will hang and become unresponsive. The mouse pointer still moves in response to the trackpad, but screen elements do not respond to clicks. I'm able to switch to a vt, stop lightdm and restart it, but sometimes an unresponsive lightdm session is left over too. I'm currently posting this in Linux but if I can get it to stay up long enough when I reboot into FreeBSD, I will post a dmesg.

Hi Jeff,

I have a similar problem but with a AMD GPU, the only chance to recover my screen is to use the power-switch on my screen (Workstation), which is not really possible with a Laptop ;) 

As a workaround you can try this as root/sudo:

/usr/local/bin/xset dpms force on

It disables the power-management for the display, sorry for not being a bigger help, i have the exact same problem since quite a long time.

Some Additional Information's about DPMS:

Comment 4 Gian-Simon Purkert 2020-10-11 11:15:33 UTC
(In reply to Jeff Joshua Rollin from comment #1)

I think that's the Problem:

device_attach: drmn0 attach returned 19

Please install 


and add 




more on that

Hi Gian-Simon,

Thanks for your help so far. Unfortunately, drm-kmod is already installed and i915kms.ko activated, but when I tried your first suggestion I got the following message: 

server does not have extension for dpms option
/usr/local/bin/xset:  unknown option force
