It is just a laptop and I'm not using any external monitors. $ lspci 00:00.0 Host bridge: Intel Corporation Skylake Host Bridge/DRAM Registers (rev 08) 00:02.0 VGA compatible controller: Intel Corporation HD Graphics 520 (rev 07) 00:08.0 System peripheral: Intel Corporation Skylake Gaussian Mixture Model 00:13.0 Non-VGA unclassified device: Intel Corporation Sunrise Point-LP Integrated Sensor Hub (rev 21) 00:14.0 USB controller: Intel Corporation Sunrise Point-LP USB 3.0 xHCI Controller (rev 21) [...] If I apt-get purge xserver-xorg-video-fbdev and remove /etc/X11/xorg.conf.d/20-intel.conf the screen will lock up as before. With xserver-xorg-video-fbdev still removed, if I re-add /etc/X11/xorg.conf.d/20-intel.conf then light-locker works again. Interestingly, xserver-xorg-video-modesetting is removed on my system too. > Regards, > - -- > Yves-Alexis > -----BEGIN PGP SIGNATURE----- > > iQEzBAEBCAAdFiEE8vi34Qgfo83x35gF3rYcyPpXRFsFAlvPPj4ACgkQ3rYcyPpX > RFu+vwf9Fye72g4ifG+dRcnYDzMyXGCC9iz+5ovkj/Vmvm2VhB1YQX22BtqurFkx > Nw3w0N5YqKto0geRmnaVUNkQgXeT4kRmhl4RGqmvYJvyfy939RY3qBNu4H7gz0m6 > F7bUMvxcB427Tbs1+AAkTDkMRvcek554Y2qFkGsfPkF19MfCIYWi2AZofon7yNPR > iWPV9emqoIUmhsIg2xptEO3+xpU+m17pDtrf763t2nP8kg8mYbzV7vyKUgmjz1Wd > dw9scn3JR8CNpjHfrL21JQhFvaVMuKZoomw8XXd6wHuh8VFo5caLU7GoOF8SMRgg > /G30+guXUHQSMlsq7JItPO9I5CLp6A== > =nwQh > -----END PGP SIGNATURE----- -- - Jeremiah Mahler
