lockscreen and standby wakeup fails

[Chris]

I am running the latest elementary os release for testing purposes from an external usb3 drive. Works well. Waking up the computer, entering a password an returning to the desktop works flawless. But in approx 1 of 10 times it won't and i get a black screen with a movable mouse-pointer. Nothing happens for about 10 minutes. I did not waited any longer and rebooted the pc. After reboot, everything works fine. This is a serious issu for me, because i leave my pc often and lock it to let software working while i am away.

Hardware: 2015 Asus Laptop, 16gb ram, i7, elementary on usb3 external hdd, external monitor via DisplayPort

keep it up guys, i like it a lot!

Can you clarify what hardware you are running this one? Do you have Skylake? Do you have a closed source video driver?

Skylake support is a bit shoddy in the kernel version Loki shipped with. I belive there was an attempt to fix this in the latest Loki iso: http://blog.elementary.io/post/150787296131/loki-release-follow-up

[Chris (crslp)]

No Skylake in my PC.
It's a Intel HM86 Express Chipset.

I did not install any drivers, it's just running out of the box.

I forgot to say, that i installed the system with virtualbox onto this external hdd (therefor the hostname with virtualbox). Actually, it's not runnung as VM.

[Zisu Andrei (matzipan)]

Could it be that Ubiquity might have installed some virutalbox specific drivers and might've skipped some bare metal ones? Would you be able to try and install Loki bare metal and confirm the issue still exists?

[Chris (crslp)]

I can't really answer your first question.
But I'll try to install it bare metal, like you said. Please give me some time (1 week). I need to schedule it around my daily work, sorry.

Take your time :P Thanks for your help.

I do have this problem. Earlier on Freya everything was fine.
My system is Toshiba Satellite c640.

[Samuel E. (benfiquista-1888)]

I have the same exact problem. I noticed that the issue happens when I leave the computer locked for several hours. If I resume within minutes, everything is fine.

Otherwise, after entering the password, the screen goes black. I see the mouse on screen but it does not move and the keyboard lights (N.Lock, CAPS) does not react.

Thank you.

[Samuel E. (benfiquista-1888)]

I just locked/unlock the screen after posting my last comment and this is what I got (see screenshot).

I switch wallpaper and reselected the previous one, the screen came back to normal.

[Chris (crslp)]

I reinstalled elementaryos-0.4-stable-amd64.20160921.iso directly to HDD. My reported problem persists.

Hi, same on Toshiba Satellite L50-B-1N2.

After a stand by, black screen and need to reboot.

AMD issue?

[Samuel E. (benfiquista-1888)]

After further testing, I noticed the issue begins when I install nvidia drivers. If I keep the nouveau right after a fresh install the issue does not happen with my setup.

Intel(R) Core(TM) i7-4790K CPU @ 4.00GHz
16GB RAM
2 x GTX 970 (SLI not activated)

thank you.

[Chris (crslp)]

I just discovered, that I was using the nuveau-driver all the time. So for me, nuveau driver doesn't seem to work well.

I now installed the nvidia-driver and see what happens. I will report in a few days.

Whenever I encounter these conditions, I have *hundreds* of instances of two processes show up in ps aux: the polkit-agent-helper-1 process, and a zenity prompt:

15237 ? windigo S /usr/lib/policykit-1/polkit-agent-helper-1 windigo
12778 ? windigo S zenity --question --display :0.0 --class mutter-dialog --title --text <big><b>“Authentication Dialog” is not responding.</b></big> You may choose to wait a short while for it to continue or force the application to quit entirely. --ok-label _Wait --cancel-label _Force Quit --icon-name face-sad-symbolic --modal

I'm not sure what is responsible for the authentication dialog, though. I can check that next lockup, if anyone knows.

I experience the exact same problem here with a Lenovo ThinkPad W520.

[Samuel E. (benfiquista-1888)]

I installed the latest NVIDIA driver (375.26) and the issue seem to be fixed.

If someone else can confirm it would be great!

Thanks

I have this same issue with Lenovo G570 Laptop

Processor : Intel(R) Core(TM) i5-2410M CPU @ 2.30GHz
Graphic Card : Hybrid Radeon HD 6370M & Intel Integrated Graphics
Linux Version : 4.4.0-65-generic

Last night I had just finished installing elementary OS 5.0 Juno running natively without dual-boot on a Chromebook c720 (Dual-Core Intel® Celeron® 2957U @ 1.40GHz with 4GB of RAM; Intel Corporation Haswell-ULT Integrated Graphics Controller). During the installation process I selected the checkbox to allow for additional third party tools but the install didn't show what those were. The install seemed to go smoothly however.

I previously had an older version of Gallium which ran fine and without [suspend] issues.

With elementary, if I suspend my laptop and wake it up within a minute or so, it seems to work fine: I see the log-in screen and can resume my work. However, I left it in that state overnight to test if all would be well in the morning but only got a black screen but could see the utility icons at the top right (wireless, battery, on/off). However, there wasn't a visible log-in field so I had to restart.

I'm newish to Ubuntu so I might need some assistance in providing more detailed info but please let me know if additional info is needed. Thanks.
