Thanks a lot Alex! I've tested out the patch, and it works for me. Laptop
screen is now lit up every time after suspend and resume. My laptop is moving
towards perfect usability on Linux!

Very nice Alex, the last patch fixes resume for me. My screen was staying black
at resume since I bought my laptop and now sleeping / resume works perfectly.
Thanks.

Just a hint: I've noticed that my display (with quirks) only somtimes does not
properly resume. (Also always from hibernation.) In both cases, it helps to
suspend to ram again and resume again and the display works again.

i tested the patch, it helps, the screen is able to recover after suspend and
resume (don't need the quirks).

I guess I can't. I don't use any patches. I just use Xorg and Mesa from debian.

With quirks like in comment #34 and in grub options.

Are you using that workaround alone, or with the pm-suspend + quirks solutions
(shown in comment #15 and comment #34) ?

I added "acpi_sleep=s3_bios" to the kernel command line, but it looks like it
didn't help. I have to run pm-suspend manually...

Resume from suspend (both RAM and disk) is broken on my system with anything
later than 3.12.x (tried 3.13.x and 3.14.x).

No idea if this helps anyone, but if your radeon card breaks suspend with the
latest kernels then try the 3.12.x series before ripping the card out - it may
work just fine.

My card is:

When testing now, it works fine. 

When I tested previously, before suspending, I might have turned off the laptop
monitor using xrandr, which is why it looked like the problem was still
present.

By the way: I've noticed that freeze > /sys/power/state causes the same issue,
only the fix does not work. It doesn't even help to suspend and resume the
computer afterwards, the display remains blank. 

Does someone have an idea on how to deal with this issue?

Hi, did you check using echo mem > /sys/power/state?

Because e.g. pm-suspend resets those parameters via
/proc/sys/kernel/acpi_video_flags. (Value should be 1, 2, or 3 if you have
kernel parameters set)

For pm-suspend to work (e.g. *Ubuntu) you need to create a file 
/etc/pm/config.d/radeon
which contains
QUIRK_S3_BIOS="true"
QUIRK_S3_MODE="true"

After poking around a bit, I found out that I can re-enable the LVDS display
using KDE's display settings (which uses xrandr), so it's just that the display
isn't turned on by default for some reason (even though it was being used
before suspend)

I tested with 3.15-git , and it looks like the kernel parameter has no effect
there - the same problem occurs again! Even with acpi_sleep=s3_bios , on
suspend and resume the laptop LVDS display is blank.

Does anyone know if this was an intentional change, to remove the ability to do
this?

Any possibility of a proper fix? Is this a bios bug? 
Workaround works on my machine but many people would probably work without
using sleep as it doesnt work oob.
thanks

For some reason, if I use it both (s3_bios,s3_mode) as kernel parameter *and*
as parameter for pm-resume, it works. Otherwise it doesn't. I had already
tested the parameters only for pm-suspend without as much success before. May
also be that 3.14 has improved things, though. Another system fixed.

Anyway,... thanks a lot! :)

Unfortunately, the "fix" is just a workaround that just calls the legacy vbios
post at resume time.  This is normally disabled for KMS because it doesn't
always work on all systems and also doesn't work with UEFI.

@Swoorup: You have a lot of other kernel parameters that may be causing
problems. Maybe you should remove some of them? 

Specifically: 
pcie_aspm=force
acpi_osi='!Windows 2012'
acpi=force

acpi_enforce_resources=lax (not sure what this does)

Neither of that work. Also I am booted in UEFI mode, if that helps?

Hey guys are you able to help me out?
I have got this on kernel parameters

pcie_aspm=force acpi_osi='!Windows 2012' acpi=force acpi_enforce_resources=lax
acpi_backlight=vendor acpi_sleep=s3_bios

However when I try to suspend, the laptop just wont suspend or it
suspends(randomly). But when I try to wake up I have got the same issue as
before: blank screen. I'd have to reboot blindly again to use the system

Adding s3_bios to kernel parameters didn't work for me. The suspend just does
not work anymore. Laptop wont suspend anymore.

Yes!

Adding acpi_sleep=s3_bios to kernel parmeters works. Now, on suspend and resume
the laptop's LVDS panel cames back to life - no external display attached.

I was able to apply this workaround "permanently" by creating a config file in
/etc/pm/config.d/ with the following line:

ADD_PARAMETERS="--quirk-s3-bios"

So, I have a temporary workaround, but it would be preferable to have this work
out of the box.

Yes, that worked! Suspending using 

"pm-suspend --quirk-test --quirk-s3-bios"

and the laptop LVDS panel works after resume.

Hi! i've been experiencing some similar issue.
(i posted in bug https://bugs.freedesktop.org/show_bug.cgi?id=43829.)

Have you tried with
sudo pm-suspend --quirk-test --quirk-s3-bios

because if i run this my screen is able to turn on after the resume. Can you
try it?

dmesg_linux_3.13.6_after_suspend_and_resume

dmesg contents for Linux kernel 3.13.6

This was recorded after suspend and resume. After resume, LVDS panel is not
displaying anything (backlight off). Attempts to turn it on manually (using
xrandr) did not work.

Note:

Suspend and resume works fine on Windows - the laptop's LVDS display is active
and working even after suspend and resume.

I remember that this problem used to occur for Catalyst as well, around version
11.5 , but it got fixed a few months afterwards, and the LVDS display was
active after suspend and resume.

I haven't used Catalyst for several months, so cannot comment on whether it
still works fine now.

I attempted to check if it was a backlight problem, following the
troubleshooting steps here: https://wiki.archlinux.org/index.php/Backlight

Booting with those kernel parameters doesn't help in my case.

Neither the driver nor the vbios uses the same crtc for clones since the
displays almost always require different timings even if they are the same
resolution.

I booted Linux 3.13.6 with the drm.debug=4 parameter - it looks like the
internal LVDS output is set to use a different CRTC than the HDMI output, even
in clone mode.

The LVDS monitor's backlight is also off, it does not switch on at all or get
enabled after suspend and resume. Only a full system restart will bring it back
to life.

I can confirm similar behaviour for A6 "ARUBA" APU without any discrete GPU, at
Samsubg NP535U3C laptop.

I still face this problem even with the 3.14-rc2 kernel

Internal LVDS display does not work, but content still displays through
external HDMI display.
