Re: Screen rapidly blanking on and off

[Ted Roche]

OP once again, attempting to wrest back the topic to a simple Inspiron
5558 i5 laptop, no second adapter, running Intel 5500 graphics.
Previously, while updating F23's updates, including many Intel drivers
and kernel 4.7.7, I continue to see the blanking behavior, in the
console before loading the desktop GNOME system.

One again, invoking xrandr in a terminal within GNOME and issuing
xrandr -r 48 (at the native 1920x1080 resolution) stops the screen
from blanking 1 second after each keystroke. Issuing xrandr -r 60
causes the blanking to restart, and reinssuing the -r 48 restores the
screen to normal operation.

Also, cold shutdown and restart will also clear the behavior. Perhaps
on reboot, the video driver is left in an unstable state.

Update: updated to F24 due to F23 EOL, and running GNOME on Wayland,
not X with this version:

 4.8.15-200.fc24.x86_64 #1 SMP Thu Dec 15 23:09:22 UTC 2016 x86_64
x86_64 x86_64 GNU/Linux

installed the latest updates via "Software" and upon reboot, the
machine was blinking again. Initial grub screen is fine and stable,
but dialog for LUKS password, sddm login screen, and GNOME on Wayland
are all blinking.

The xrandr trick no longer works, since Wayland isn't X. Cold shutdown
and restart did resolve the issue.

I find BZ fairly hostile. Can anyone suggest an existing bug report,
or the proper component to post this to?

 In my case I see instants of black screen on a Lenovo P50 with
 Fedora 24, using Intel graphics.

 Looks like a refresh problem, or maybe something related to switching
 the panel to the right gfx adapter (there is a dormant nvidia too,
 with nouveau blacklisted).

 My compositor is kwin.

I do not have the nvidia binary driver ("dormant nvidia" was referring to 
hardware).
I blacklisted nouveau, so only the Intel graphics is available.

By "switching" I was intending that when you have two graphics adapter, the 
physical
connection of the LCD panel to the adapter output happens through a switcher,
controlled by software. Having some moments of black screen, I was wondering
if the switch was going to nvidia and back to intel for some strange reason.

Re: Screen rapidly blanking on and off

[Ted Roche]

OP, here. The Inspiron (5558) has built-in Intel 5500 graphics.

Plugging in an HDMI external monitor and enabling it with the
"Display" applet in Settings causes the internal display to return to
the blanking behavior.The external monitor does not blink.

Using GNOME 3.18.2.

Playing a Youtube video in Chromium on the external monitor causes the
internal laptop display to stop blanking. Scrolling down the page
until the video is no longer visible, and the blanking starts
immediately.

Thinking this is some "blank on inactive" timer gone wild. Any
suggestions on what to look at or poke around in?

He means that if you have multiple graphics adapters, does switching
your display to one of the other adapters exhibit the same problem.
Since your T530 only has one graphics adapter, that doesn't apply. I
guess you could try using an external monitor and see if the problem
persists.

Re: Screen rapidly blanking on and off

That has all the earmarks of something having set the screen
blanker to go off with a delay of just a few seconds. I think
most video players temporarily disable the screen blanking.
Usually that setting is under some "power management" control
panel thing. You might see if you can find it and disable it.

I've also see systems that had this effect because something
screwy in the kernel was running the clock at warp speed so
it thinks a long time has passed since it blanked the
screen, but it hasn't really.

Re: Screen rapidly blanking on and off

More data: if I open YouTube on a tab in Google Chromium and play a
video, it plays steadily and doesn't blank.

Opening a terminal and typing xrandr yields:

Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767
eDP1 connected primary 1920x1080+0+0 (normal left inverted right x

Issuing xrandr -r 48 and the screen is steady and not blanking.

Issuing xrandr -r 60 and we're back to the blanking.
