[Samsung NP535U4X-S01TH] Ubuntu 14.04 blank screen after wakeup from sleep

[Ubuntuser]

HOW TO REPRODUCE

1. Suspend the device
2. Wake it up

EXPECTED BEHAVIOUR

- The device to resume normally

REAL BEHAVIOUR

- The screen goes blank

RELEVANT DETAILS

- In the "/etc/default/grub" file; changing "quiet splash" option to "nomodeset" allows the wakeup, but the computer gets so slow it is unusable.

WORKAROUND: Install fglrx.

Unverified WORKAROUND: Revert commit 6c7bccea390853bdec5b76fe31fc50f3b36f75d5 as per https://bugzilla.kernel.org/show_bug.cgi?id=76761#c3 .

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[shookees (shookees)]

Currently, after the lock screen update, when waking up - it freezes on lock screen. I'm also using ati drivers.

[Ivan Helguera (gokmar)]

same problem here, with a Series 5 Samsung running AMD A6 - dual graphics radeon. It must be said that the open-source graphics works way better in 14.04 then before.

[xop (skhoroshavin)]

I have ASUS K73SV notebook with dual graphics intel/nvidia. I'm using default intel driver, no proprietary drivers installed, and this bug also affects me.

1) Xubuntu installed from fresh daily build wakes up to login screen, after logging in screen turns blank, but hardware is alive - I can Ctrl-Alt-F1 to console and restart lightdm, after which I can login to desktop

2) Ubuntu installed from fresh daily build wakes up to login screen, after logging in all previously opened applications are closed, as if lightdm was restarted silently

In both cases all previously run applications are closed, so suspend is unusable. In case of Ubuntu last information in /var/log/Xorg.0.log.old is:

Native resolution of my screen is 1600x900, so these resize attempts are quite weird.

[xop (skhoroshavin)]

Seems like I've just found a workaround for my case. This log entry caught my attention:
[ 6508.900] (II) intel(0): resizing framebuffer to 2624x900

I've checked ubuntu displays settings and found that besides built-in display I have some weird unknown 1024x768 display which is enabled. After disabling it I've sent my notebook to suspend, and after waiting for 2 minutes I was able to successfully wake it up. Hope this helps.

[Alberto Salvia Novella (es20490446e)]

It renders the system temporarily or permanently unusable.

[eric aquaronne (eric-aquaronne)]

same issue on Lenovo X220, returning from suspend (clsing the laptop lid), there is a random screen content but it is impossible to enter the password and to logon, only recovery for me is to reboot th system: not good

[eric aquaronne (eric-aquaronne)]

here is the /var/log/Xorg.0.log.old from the above append

[Kacper Hęćka (kacperh20)]

ok, so i found this "temporarly fix". When you are using laptop, first lock your screen and then close lid to sleep mode. After you open lid system will work ok, but notifications area will show: "Power Manager not authorized". I'm also have raden card (IBM t43).

[martini (mr-owner-gmail)]

The same bug on Samsung with Intel graphic.

Thanx Kacper! It works for me in Xubuntu (with same "Power Manager not authorized").

[Piotr Sokół (psokol)]

The same problem here, on Samsung rf511 with Intel chipset.
I my case this is related with unknown display that I found in gnome-control-center. At beginning I turned it off and now I realized this prevents from waking up. It is really annoying, because I can only have one workspace enabled, cannot use dynamic workspaces and my mouse cursor travel behind the screen edge.

[martini (mr-owner-gmail)]

In my Xubuntu there are not any unknown displays, and no ATI just intel, but bug is present.

[Akshar Patel (akshar-patel-47)]

I'm using xubuntu daily build. I'm using the opensource ATI drivers. I can recreate this bug everytime.

[stevepowell99 (steve-promente)]

yes, I have the same problem with intel drivers but only when using gnome-shell, not xubuntu. I have just updated to 14.04 today after using the beta. Kacper's workaround works for me.

[Viktor (clicman)]

Same issue with lubuntu laptop on nvidia-173 drivers (C67 chip)

[Atul (atulkakrana)]

Same problem with default drivers on Dell Studio with ATI Raedon card.

Atul

[Adam (9-ubuntu-8)]

Same issue on an Lenovo ThinkPad T510 (i7 with nvidia NVS 3100M with nvidia 331 drivers) running XFCE (Xubuntu). It seems as if light locker in combination with dbus causes the problem.

Thank you Kacper for the hint. I turned off 'lock on suspend' in the light locker settings. This is not what we want, but an exceptable work around.

I wonder if they actually tested suspend/resume before releasing 14.04 if something like this happens?

[Máté Eckl (ecklm)]

Same for me on r Toshiba satellite c855D-l5V with AMD A8-4500M APU. That workaround doesn't work for me.

[Stefano Cipriani (cipria91)]

Same here on Acer V5-551 with AMD-4455m and Radeon HD7500G

[Marcin (q-marcin)]

Same problem here, Lenovo e520, radeon HD6630M

[Mark Bos (bosmark88)]

Same problem here,
Asus K55A ( Intel Core i5 3210 / Intel HD4000 )

[Gargoulf (pasquiernoterdaeme)]

Same pb here.
Dell precision M6500. Fresh install of ubuntu 14.04 64bit.

[Artyom Nosov (artyom.nosov)]

Same problem,
ASUS N56VZ. xubuntu 14.04 (amd64).

[Fabio (mr-fabio90)]

Same Here! (I would say..from time to time)
Samsung 535u3c A03
AMD A4 4355M
RadeonHD 7400G

Please solve this BIG bug..open-source driver runs much better then proprietary one on amd trinity machines.
I should write a guide for optimizing ubunu on trinity apus..cause I'm fighting with those cpus(and gpus) from 12.04 release..
Thank you all!!

[Fabio (mr-fabio90)]

I forgot..I'm on Ubuntu 14.04 (full release)

[Nikos K (kyriakoy)]

Same problem,
HP Pavillion dv6500 xubuntu 14.04 (amd64).
After suspend, blank screen, after ctrl-alt-del, unable to unlock

[Kacper Hęćka (kacperh20)]

[UPDATE] ok so i tested ubuntu and lubuntu (both 14.04 LTS) and the sleeping/resuming works perfectly, but in Xubuntu 14.04 i still have black screen after wake up from sleep mode. Maybe someone can tell where are differences between these three distros? Anyone?

[DavidSH (laun0hpad)]

I have the same problem on old Dell 1525 laptop with an update to Ubuntu 14.04 final release from 13.10.

 I seem to have temporarily fixed the problem by doing the following:

Go to Security & Privacy - Un-check the ticked boxes under
Require my password when
'Waking from Suspend'
and
'Returning from Blank Screen'
i.e. no passwords needed after suspend

This seems to be working so far and the machine wakes up okay after I shut the laptop lid and the machine has entered suspend mode. Whether it's a full fix I don't know, but it is working for now.

[TEN (launchpad-20-ten)]

According to #5 & 11 this regression also affects Nvidia & Intel, cf. https://bugs.launchpad.net/ubuntu/+source/pm-utils/+bug/999638 & https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1283938
Nor is it limited to laptops (with lids): Also affected on HP Compaq dc7800 Convertible Mini Tower with GT520 card.

[Cedar (c-rosenfield)]

I'm affected. Fresh install of Xubuntu 14.04 64-bit. Toshiba Satellite L755-S5110 (Intel Core i3 2350M, graphics are Intel GMA HD 3000).

[Bryce (brce)]

Also affected. Upgraded from Xubuntu 13.10 to 14.04 64-bit. Acer Aspire TimelineX Intel i5-2410M, Intel graphics.

[marlio (marliob)]

Same bug in my Sony Vaio, fresh install ubuntu 14.04 64-bit.

[Kacper Hęćka (kacperh20)]

Update no2 Funny stuff, I deleted xfce4-power-manager, reboot, and put my laptop in sleep mode. After it wake up, desktop shown up (without entering password) and my mouse cursor disappeard!? Wtf !?

[Carl Menke (halfburnttoast)]

This also effects my laptop (xubuntu 14.04 x64)

Toshiba Portege R835-p70.
Intel core i5-2410M
Mobile Intel HM65 Express
Intel HD Graphics 3000

Steps to reproduce:
1. Reboot computer
2. Log in normally
3. Close lid and allow computer to enter sleep
4. Wake computer (login screen appears)
5. Enter password to unlock session

The screen will immediately go blank (both backlight and LCD). Switching to a virtual terminal or SSHing into the box works fine.

[Fernando Perez (fdo.perez)]

Confirming this on a desktop machine, Intel(R) Core(TM) i5-2500K with built-in Intel graphics and no additional video card at all.

Suspend/resume was working just fine on 13.10. After upgrade to 14.04 suspend still works, but upon resume the screen is blank. The only way to get it back is to go to a text console and force-kill X so it respawns.

I'm running KDE as my desktop, in case it matters.

[Tomo Popovic (tp0x45)]

Confirmed on several PCs:
- System76 Lemur
- Asus X202E
- Dell Optiplex desktop

Just like in post #36 and others. Workaround in #10 is helpful although it does not solve the problem.

[Volodymyr (v-makarchuk-v)]

the same bug on ubuntu gnome 14.04, i fix this bug by turning in suspend mode after pressing power button

[Volodymyr (v-makarchuk-v)]

to above comment my laptop: hp dv6, cpu:core i5 240m, graphics : ati 6 mobile seria

Fabio, so your hardware and problem may be tracked, could you please file a new report with Ubuntu by executing the following in a terminal while booted into the default Ubuntu kernel (not a mainline one) via:
ubuntu-bug linux

For more on this, please read the official Ubuntu documentation:
Ubuntu Bug Control and Ubuntu Bug Squad: https://wiki.ubuntu.com/Bugs/BestPractices#X.2BAC8-Reporting.Focus_on_One_Issue
Ubuntu Kernel Team: https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Filing_Kernel_Bug_reports
Ubuntu Community: https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette

When opening up the new report, please feel free to subscribe me to it.

As well, please do not announce in this report you created a new bug report.

Thank you for your understanding.

Helpful bug reporting tips:
https://wiki.ubuntu.com/ReportingBugs

[Ubuntuser (ubuntuser1404)]

Can somebody affected from the bug, please try to apply this patch to the kernel: https://bugzilla.kernel.org/attachment.cgi?id=137741 ?

(https://bugzilla.kernel.org/show_bug.cgi?id=76761#c3).

This is a driver problem and should be treated from a kernel specialist...Is there any Ubuntu Community developer or Canonical tech available? This bug is affecting more than 100 people subscribed from 7 - 8 months.

Thanks.

[penalvch (penalvch)]

Ubuntuser, bug heat, and how many people mark themselves affected is irrelevant, as the same symptom can manifest itself via different root causes, and hardware. Anyone who thinks they may have the same problem would need to file a new report, or risk waiting for a fix to a problem that wasn't theirs to begin with.

If you want your problem addressed, you already have been advised on what needs to happen next. Having a production laptop means if you are that worried, backing up your data, which you should be doing anyways, and testing the patch.

[Ubuntuser (ubuntuser1404)]

I installed git, tomorrow i will try the patch, i just think that maybe there are more expert people into the group looking for this bug solved.

Thanks

Ubuntuser, you would want to contact the Ubuntu Kernel Team for testing support via IRC or mailing list -> https://wiki.ubuntu.com/KernelTeam#Communications .

As well, please do not mark attachments as patches, as it would not be accepted as a patch into Ubuntu as you previously created it.

darkmoonsinger, nobody is replying, nor contacting you directly, you subscribed yourself to this bug report. If you don't want to see e-mails related to it, then click Mute bug mail in the top right of report.

I didn't receive answers from my last email to the kernel team.

Please Christopher, could you contact your colleagues and prepare a proper solution (patch to test) with them?
I give you my availability to test your final patch.

Same problem here. Using radeon HD 8500 on 14.04.

When using the standard ubuntu supplied drivers, It will just go into sleep/powersave modus when suspending or switching a user.

When using the AMD drivers (fglrx) , it goes to a black screen, with only the mouse pointer showing (and I have to power down).

Not a good bug if you have a system with multiple users.

And we're going into the new year with the problem is still not fixed.
The bug manifests for me on ThinkPad Edge 02213BG, Radeon graphics, freshly installed Xubuntu 14.04.

[bronlund (bronlund)]

This is just so annoying!

[Darek (darekx2)]

Yes it's annoying ! The problem is old and for now still exist.

[m33x (maximilian-golla)]

This affects a user several times a day. If I come back from lunch, I have to reboot my notebook. This is really annoying. Please consider to fix this.

[SupportGuy (3-admin-labs)]

I started seeing random freeze while resuming from sleep/hibernate on my 5 year old system after I switched to ATI open source drivers, since the Catalyst drivers are no longer supported for my hardware on trusty and precise. The open source driver claims to better or same as the Catalyst, but looks like this is not the case.

This bug will never be fixed. Ubuntu team is more focused on mobile environment than desktop now. Too bad.

[Peter Ludwig (peter-ludwig)]

Could it be that the problem is related to the size of the swap file? The swap file needs to have same size as physical ram?

[Caleb (caleb89)]

@peter-ludwig I reckon you're right. My Ubuntu machine used to be able to sleep fine, but I have 16GB of RAM so I lowered my swap file to be 2GB - it can no longer sleep! Makes me sad. But makes sense.

[Caleb (caleb89)]

Update: Just completely removed my swap partition and Ubuntu tries to "Suspend" but ends up just locking the screen

[Kenneth Bogert (kbogert-uga)]

This just happened to me and got some messages in dmesg, filed bug 1442311

[atimonin (atimonin)]

After some time I've noticed that the bug is fixed (at least for my samsung NP535)
Sleep-Wakup works as expected.
Looks like some of updates fixed this bug.

[Kenneth Bogert (kbogert-uga)]

For me the fix was to add:

export CLUTTER_VBLANK=none

to /etc/environment

[Samarth Mathur (samarth-math)]

Please fix this guys,

It's killed a work system for many.

[foxyterkel (terkel-d)]

Had the same bug on Ubuntu 14.04, and now got it again on Linux mint 17.02 cinnamon. Also noticed that after forced reboot black screen, i'm unable to change brightness by hotkeys. Fujitsu AH544, intel/nvidia.

[Konstantin (humansfriend)]

Same bug in ubuntu 14.04

[ggallozz (ggallozz-gmail)]

Me too have browsed around for a while, and now I can affirm that the proble affect many many users, on different PC an video cards and drivers.

I can say that on my PC is installed Xubuntu 14.04.4 and on another partition Ubuntu Mint 14.04.3. On this last system, resume works ALWAYS fine ....

[Kenneth Bogert (kbogert-uga)]

Just to update my earlier comment #203, I still had this bug occur occasionally even afterwards, though at a reduced rate. After doing some more testing recently, I've been able to avoid this problem completely by turning off the System-monitor extension in Gnome tweak tool. I was then able to revert my change in #203 with no issues.
