Hello,
I have a Dell L502x which have a optimus Graphic Pack:
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core
Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA
controller])
Subsystem: Dell Device 050e
Flags: bus master, fast devsel, latency 0, IRQ 51
Memory at f1400000 (64-bit, non-prefetchable) [size=4M]
Memory at e0000000 (64-bit, prefetchable) [size=256M]
I/O ports at 4000 [size=64]
Expansion ROM at <unassigned> [disabled]
Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit-
Capabilities: [d0] Power Management version 2
Capabilities: [a4] PCI Advanced Features
Kernel driver in use: i915
Using driver:
2.99.905+git20131023.b70390b4
When I use a DELL U2713HM Monitor on the DisplayPort, it will flash blank
for 5 seconds in a 10 minutes interval.
The monitor is at 2560x1440 (60hz).
This is not ideal, but I can live with.
The big problem is when using bumblebee with intel-virtual-output -b.
In this case the monitor will enter in energy save state instead.
The only way back is to turn it off and on with xrandr:
xrandr --output DP1 --off
xrandr --output DP1 --auto
The odd thing is if I use instead a Mini DisplayPort adapter to a Dual DVI
output, this problem will not happen.
The downside of this solution is that I will need to add a new mode at 41hz
with:
xrandr --newmode "2560x1440_41" 162.00 2560 2608 2640 2720 1440
1443 1448 1468 +hsync +vsync
So, What I am looking at is the source of the problem:
If the source of the problem is the driver, which debug information should
I provide?
Or is it a problem with the DP of the monitor?
Or a problem with the Display Card?
Or should I lower the frequency in the DisplayPort (as with the DVI)?
thanks
-rsd

Please provide dmesg with drm.debug=0xe module parameter from early boot
to the problem. If the problem takes a long time to reproduce, you can
provide two dmesgs, one from early boot and another covering the
problem.

Hello,
The dmesg for the boot is this:
http://pastebin.com/aXJQiprL
The dmesg when the flashing started to occur:
http://pastebin.com/GkRcpK80
I kept the config a simple as possible. No bumblebee, just LVDS1 and DP1
without adaptors.
my Xorg.0.log is this:
http://pastebin.com/2vK37TNr
Thanks!

I don't see anything particularly wrong with that. There's the
occasional dimming of the backlight - that's not what you're referring
to is it?
Could you describe the problem a bit more please?

I will put into a few scenarios:
1 - LVDS1 + DP1
Dell U2713HM using a Display Port cable (display) to a Mini Display Port
(Notebook).
No adapters.
This is where the logs belongs to.
Some random time after boot (15min, 1hour), the DP1 screen will blank for
a period between 2s to 5s and come back again.
This will keep repeating for 5 to 15 min endless.
2 - LVDS1 + HDMI1
In this case, the U2713M display is using the HDMI port and a HDMI do mini
Display Port adapter.
I can get the 2560x1440 resolution only if I lower the frequence to 41hz or
lower (which I believe is a HDMI limitation).
No problem at all.
3 - LVDS1 + DP1 + VIRTUAL2
Same as (1) with and extra screen on bumblebee: intel-virtual-output -b
This time the U2713M display enters in sleep mode instead of blanking and
does not come back (by itself).
I believe this is the same trigger from (1), but for some reason it is not
just blanking.
To revert this, I have to use xrandr to turn the display off and on
(--auto).
4 - LVDS1 + HDMI1 + VIRTUAL2
Same as (2) with bumblebee.
No problem at all too.
I am not sure if this could be a faulty display or cable if not the driver.
(or how to detect it).
Thanks again.

I too am having the same issue. I'm running on kernel 3.12.6 (just updated)
The issue happens less frequently, but it still happens and it's quite
annoying.
Previously I would just get lines like this:
[ 342.071567] [drm:ilk_display_irq_handler], Pipe B FIFO underrun
[ 342.071584] [drm:cpt_serr_int_handler], PCH transcoder B FIFO underrun
But after the recent kernel update it looks like there are some more debug
messages being sent out like this:
[ 624.430107] [drm:i915_driver_open],
[ 624.439972] [drm:i915_gem_context_create_ioctl], HW context 1 created
[ 624.450177] [drm:i915_gem_context_destroy_ioctl], HW context 1 destroyed
I have a bug open for this, but I haven't heard a response on next steps
unfortunately :(

I've gone ahead and updated to the latest nightly:
Linux rnavarro-thinkpad 3.13.0-994-generic #201401100405 SMP Fri Jan
10 09:05:49 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
The release done on 1/10/14
I'm still getting the underruns, they're actually a bit more frequent
now. Right after I logged in I got one one my second monitor, and then
shortly after another on my first.
The latest log can be found here (01-10-2014 drm-intel-nightly):
