Xorg log
Hi,
I first noticed this little bug a few months ago on my old Ivybridge laptop,
then saw it again today on my Kabylake laptop. Due to heavy flickering in
Chrome with SNA I still like to use UXA (this bug doesn't happen with SNA or
modesetting).
Unblanking the screen shows a visible cursor but a black screen unless I do a
VT switch, then the unlock window to enter credentials appears.
This seems to be present on the old Gnome and graphics stack from Debian Jessie
as well as an up-to-date Debian Sid.
This doesn't happen when resuming from suspend.
I have the latest xf86-video-intel from git with debugging enabled if anyone
wants to poke at this.
I attached Xorg.0.log and dmesg; some of the noise earlier is me testing
suspend.
The main way to test is just to go to Power in settings and set "Blank screen"
to 1 minute. Further complicating things is that if you do "xset dpms force
off" this issue doesn't happen either, making me think screen locking is
involved.
Thanks!
Tod</pre>
