Suspend after close lid not locking screen on wakeup


Post by forliberty » Sun Sep 16, 2018 10:20 am

Longtime Linux user, noob to MX. System is not locking screen after resume from suspend due to lid close. System DOES lock screen if (1) the suspend is initiated manually by pressing the Suspend button or (2) suspend due to inactivity. This is a critical security issue for me. I have set the system to lock the screen when the system goes into suspend. Tried the fix suggested in this post, as I too have Intel graphics, but no improvement: http://forum.mxlinux.org/viewtopic.php?t=44692

Here is the output of inxi -Fxz:

Just for ease of reference, so folks don't have to dig through other threads, here is the fix that I tried:

Make this text file
with this content:

Code: Select all

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "TearFree"     "true"
Interestingly, this DID fix a screen tearing problem that I had.
