Bug #: 42960 Summary: Display does not work when resuming from suspend Classification: Unclassified Product: DRI Version: XOrg CVS Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: major Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: sandy.8925@gmail.com
I have an ASUS K53TA laptop.
Relevant specs: AMD A6-3400M APU with integrated Radeon HD6520G and a discrete Radeon HD6650M. Both are connected through Crossfire (I think). Laptop display is though the integrated card.
Software info: Ubuntu 11.04 64 bit using Linux 3.2-rc1 kernel from kernel.org and xorg-edgers PPA
After resuming from suspend, display does not work.

--- Comment #8 from leon_ti@mail.ru --- I can confirm similar behaviour for A6 "ARUBA" APU without any discrete GPU, at Samsubg NP535U3C laptop. leon_ti@leonid-samsung:~$ uname -a Linux leonid-samsung 3.12.0-031200-generic #201311031935 SMP Mon Nov 4 00:36:54 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

--- Comment #9 from Sandeep sandy.8925@gmail.com --- 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.

--- Comment #10 from Alex Deucher agd5f@yahoo.com --- (In reply to comment #9)
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.
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.
https://bugs.freedesktop.org/show_bug.cgi?id=42960
--- Comment #11 from Sandeep sandy.8925@gmail.com --- 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.
https://bugs.freedesktop.org/show_bug.cgi?id=42960
--- Comment #12 from Sandeep sandy.8925@gmail.com --- 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.

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.

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?
https://bugs.freedesktop.org/show_bug.cgi?id=42960
--- Comment #16 from Sandeep sandy.8925@gmail.com --- Yes, that worked! Suspending using
"pm-suspend --quirk-test --quirk-s3-bios"
and the laptop LVDS panel works after resume.
https://bugs.freedesktop.org/show_bug.cgi?id=42960
--- Comment #17 from Sandeep sandy.8925@gmail.com --- 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.

--- Comment #28 from Sandeep sandy.8925@gmail.com --- @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)

--- Comment #29 from Alex Deucher agd5f@yahoo.com --- 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.

*** Bug 73882 has been marked as a duplicate of this bug. ***
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! :)

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

--- Comment #32 from Sandeep sandy.8925@gmail.com --- 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?
https://bugs.freedesktop.org/show_bug.cgi?id=42960
--- Comment #33 from Sandeep sandy.8925@gmail.com --- 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)

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"
https://bugs.freedesktop.org/show_bug.cgi?id=42960
--- Comment #35 from D djtm@gmx.net --- 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?
https://bugs.freedesktop.org/show_bug.cgi?id=42960
--- Comment #36 from Sandeep sandy.8925@gmail.com --- 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.

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.
