[Ubuntu-x-swat] [Bug 1283938] Re: Ubuntu 14.04 blank screen after wakeup from sleep
@biolyasser: I installed Sabayon 14.04 minimal version, restore still did not work. It was running just fluxbox. I had to use echo mem /sys/power/state since other ways to suspend (like pm-suspend) were not there. It did suspend but resumed to black screen as usual, except this time it had an underscore char showing in the upper left. It was a 3.14 kernel. I am using nvidia, and have found no difference between nouveau and nvidia drivers as far as the bug goes. This problem could be kernel related. For example, on debian wheezy (3.2 kernel) which doesn't have the bug, if I install the backported 3.13 kernel, it will now have the bug. Most of the action about suspend/restore bug(s) is on the kernel.org bug site. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1283938 Title: Ubuntu 14.04 blank screen after wakeup from sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-trusty/+bug/1283938/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

@biolyasser: I tried installing a fresh copy of Mint/xfce on a spare partition, on my machine it has the same resume problem as every other recent distro version I've tried. The only working versions for me are not recent: Ubuntu 13.04, 13.10 and Debian wheezy. One interesting thing that may or may not be related: doing cat /sys/power/state gives the following: standby mem disk on older versions where suspend/resume works freeze standby mem disk on versions where suspend/resume is broken -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1283938 Title: Ubuntu 14.04 blank screen after wakeup from sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-trusty/+bug/1283938/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1283938] Re: Ubuntu 14.04 blank screen after wakeup from sleep
Confirming same problem (desktop machine, Asus MB minimal system, nvidia card). Resume from suspend powers up (fans, disk, backlight) but just get black screen, kernel appears wedged, hard reset required. This is 14.04, both new install and upgrade from 13.04 same problem. Nvidia proprietary driver or nouveau makes no difference. I've tested this with different distros (all on the same machine), result: Ubuntu 13.04: resume works Ubuntu14.04: resume broken Debian wheezy: resume works Debian jessie/testing: resume broken Mint (recent): resume broken In /var/log/pm-suspend.log, there's nothing after performing suspend. Testing echo mem /sys/power/state to do the suspend: 13.04: resume works 14.04/jessie: resume broken -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1283938 Title: Ubuntu 14.04 blank screen after wakeup from sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-trusty/+bug/1283938/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

@chaas Re Mint, that might make sense - I was running Mint Debian w/ MATE, which is based on Debian testing, which I found also has the problem. Are you running Mint 16? I don't know it lineage (I don't know much about Mint), but assume it's not based on Debian testing. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1283938 Title: Ubuntu 14.04 blank screen after wakeup from sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-trusty/+bug/1283938/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
