Black screen after pm-suspend

Last week I purchased a hp dv6 and immediately installed arch linux as the only operating system.  So far, everything seems to be working fine except that the screen will not turn back on when the laptop resumes from its suspended state.  I am using acpid and pm-suspend to successfully achieve the suspended state.  I know for sure that the laptop has successfully resumed operation because I am able to run commands including more suspends through sudo pm-suspend and even complete shutdowns though sudo shutown -h.  Obviously the screen does not turn on at all and remains black throughout. 

I have scanned the wiki, but the solutions I have found are focused on problems with the computer not resuming.  My computer seems to be resuming just fine except for turning the screen back on.  Any help would be greatly appreciated.  I use arch linux extensively and every day smile  for work (hp dv5), and I am looking forward to using my dv6 the same way.

Re: Black screen after pm-suspend

I'm having the same exact problem, but my computer is a Lenovo Ideapad. Here is some hopefully useful info:

I'm using the /etc/acpi/handler.sh script to suspend it when the lid is closed. I basically used what was on the acpid wiki page, and acpid is in my daemons array. Handler.sh:

Here's what I'm doing: I have music playing, and a terminal with "sudo halt" typed in already. Then I close the lid and the music stops. Then, I open the lid, and the music resumes, so I know it has essentially woken up. Then I enter my password and hit enter, and the music dies and the machine is clearly off. So it's definitely waking up, but the screen just isn't.

This is very frustrating, what can we do?

Thanks!

Additionally, I have tried the thing it suggests here: https://wiki.archlinux.org/index.php/Pm … om_suspend

It didn't work, same thing happens.

Re: Black screen after pm-suspend

Do resume-from-hibernate work for you?
For me it work, but i cant start x server after resume or hibernate with any x server running (kernel panic)

Re: Black screen after pm-suspend

I'm also having problems with resuming from suspend... But I think my main problem is AMD proprietary driver. When I install FOSS AMD (ATI) drivers, I can normally resume from suspend, but after installing Catalyst drivers (catalyst-total) I can't anymore. As I can remember I had the same problem with Mint installation, so it's not Arch only.
BTW my hardware is Acer Aspire One 722 (AMD APU C-60 with Radeon HD6290m).

Re: Black screen after pm-suspend

Here is a suggestion to help isolate what is going on.  Did you know that transmissive mode LCDs (ones with backlights) can operate (poorly) in reflexive mode?  I am wondering if the display came back to life, but the back light is off.  Is it obvious that the back light is coming back on and the LCD is just displaying a really good black, or could the back light be off while the LCD is trying to display a good image?

Try this:  Find a place that has low ambient light, take a flashlight (torch) and illuminate the screen from a angle off to the side.  Position your eye so that you do not get glare or spectral reflections from the flashlight.  In the area illuminated by the flashlight, is there an image being displayed?

Tried it yesterday, the screen is totaly off. If off like when the laptop is shutdown.

Re: Black screen after pm-suspend

Has anyone tried suspending to ram using the user space suspend (uswsusp) functionality instead of pm-suspend?  Also, has anyone tried successfully to use the hibernate-scripts.  Arch boots up so fast, that hibernating becomes a viable alternative for me.  I just need the ability to close my laptop lid and re-open it later to find my workspace just as it was when I closed the lid in the first place.  A possible direction to pursue . . . pmCyanide (above) mentions that suspend worked fine using the FOSS AMD (ATI) driver.  Does that indicate that the problem is related to the video card or driver and not to the Arch set-up at all?  It seems that everyone on this thread is using AMD and ATI.  If that is the case, how can this driver be obtained and installed without the catalyst?  By the way . . .  I wonder if there seems to be a difference in whether we are running syslinux or grub2?  When I started this thread, I was using syslinux.  Just in case it makes a difference, I am now doing a complete re-install of Arch on a clean freshly formatted hard drive using grub2 as the boot manager.  I will report back on progress.  If the problem persists, I am going to try changing the driver.

I have tried with uswsusp, trieng with all the diferent different, couldn't get it to work sad, think it will work with the proprietary driver, but some of you don't like the proprietary driver smile Kernel 3.5 have just been available in arch, so i will see if it change anything, that should at least give some more performance.

Re: Black screen after pm-suspend

Any more ideas? Is this just a horrendous bug?

Re: Black screen after pm-suspend

I was able to get the pm-hibernate (suspend-to-disk) functionality working by following the wiki . . . . There is a strange behavior, though.  The laptop tried to resume imediately after the hibernate completed which threw an error.  Then I changed one line in the configuration file to say that the suspend state = shutdown.  (Again, that hint was in the wiki.)  Now the system correctly hibernates and resumes just as expected.  I still get the error complaining about something not being found, but the error seems to be related to the computer attempting to resume immediately when the hibernate completes.  The config file is preventing that from happening, so the computer obediantly shuts down (hibernates) and the "error" seems to be completely benign.  The resume correctly locates the swap partition and loads happily and quite quickly too.  I have not checked to see if the wifi and ethernet restart as they should.  Then I loaded uswsusp to try to use that method.  The HP-DV6 is not on the white-list, and suspend-to-ram did not work in the default configuration.  Klausenbusk said he tried all the config combinations and did not get it to work, but I do not kow for sure that he has the same model computer as me.  That's where I left it last week.  Now I am 18,000 km away from home (and from my new computer) still working on my fully-functional smile Arch installation on my DV5.  So, I will not be able to try anything new for a couple of weeks.  Klausenbusk also mentioned that the new kernal was available.  Since I am away from home I have not been able to update my DV6, but I did update my DV5 without any problems.  smile  If anyone has figured this out, please post in this thread.  Also, does anyone know for sure that the proprietary driver really fixes this issue?  If so, kindly provide brief instructions on how to do it.  The wiki for proprietary driver looks quite daunting.
