Description of problem: System does not correctly restore video state after waking from suspend. At least backlight is kept off. Hardware profile can be checked here: http://www.smolts.org/client/show/pub_9d7fe254-01da-40af-ab77-93ed9260d8a4 System usually is not fully hanged, as I can blindly enter commands, remotely ssh into the PC, etc. If I suspend with X running, sometimes I get a hard hang when coming back from suspend (no caps lock, no network, ...). If I use pm-suspend from a terminal without having loaded X (runlevel 3), the system _never_ hard locks. Tested with nouveau 2012/09/25 TestDay LiveCD. Attached dmesg with enlarged log buffer and drm.debug=14, but there are no errors logged.
Created attachment 617463 [details] dmesg.out for suspend cycle with drm.debug=14
Kernel: 3.6.0-0.rc7.git0.1.fc18.x86_64 SMP Nouveau: xorg-x11-drv-nouveau-1.0.1-6.fc18.x86_64
I found exactly the same problem after an upgrade from F16 to F17. F17 uses vmlinuz-3.5.4-2.fc17.x86_64. I simply install the 1st F17 released kernel 3.3.4-5.fc17.x86_64 and waking from suspend now works perfectly. I didn't test kernels between those two versions.

Jacobo and Nicolas, are you able to reproduce it on latest Fedora 18 or 19?
I'm still using Fedora 17. However, my Nvidia card is dead and I replaced it with ATI 5450. I'm still using nouveau. Waking from suspend works fine now. Here is my profile : xorg-x11-drv-nouveau-0.0.16-37.20120306gitf5d1cd2.fc17.x86_64 linux : 3.8.13-100.fc17.x86_64
Nicolas, if you switched to ATi, you use radeon driver now, not nouveau. Nouveau is just installed. You can check what driver you use by running following command: lsmod It's on you Jacobo, can you reproduce this bug now?
Also affects Fedora 19 Using 2 graphic cards, integrated Intel HD 3000 and geforce GT 630m. Hibernate works right but waking up from suspend to ram hangs the system, black screen and no backlight $ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 630M] (rev a1) $ lsmod | egrep "i915|nouveau" nouveau 943445 1 ttm 79865 1 nouveau i915 656126 4 i2c_algo_bit 13257 2 i915,nouveau drm_kms_helper 50239 2 i915,nouveau drm 278576 8 ttm,i915,drm_kms_helper,nouveau i2c_core 34242 7 drm,i915,i2c_i801,drm_kms_helper,i2c_algo_bit,nouveau,videodev mxm_wmi 12865 1 nouveau video 19104 3 i915,acer_wmi,nouveau wmi 18697 3 acer_wmi,mxm_wmi,nouveau Packages installed: kernel-3.11.7-200.fc19.x86_64 xorg-x11-drv-nouveau-1.0.9-1.fc19.x86_64 xorg-x11-drv-intel-2.21.12-2.fc19.x86_64
This message is a reminder that Fedora 18 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 18. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '18'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 18's end of life. Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 18 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 18's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
