Black screen after return from login #165

Open otavioschwanck opened 6 years ago

otavioschwanck commented 6 years ago

When i lock screen and log in again, the elementary show me a black screen for +/- 10s.

[edit] PARCIAL FIX:

remove light-loger and install gnome-screensaver

sudo apt remove light-locker && sudo apt install gnome-screensaver.

Then, add gnome-screensaver-command -l to a shortcut to use it:

Observation: I'm using padoka ppa for latest drivers, but this issue happens with default drivers too.

Same here.

Dell LATITUDE 7490, 16GB RAM, Core i7 8th gen.

beeblebrox3 commented 5 years ago

Seems like the same issue in here: https://github.com/elementary/greeter/issues/137 Same problem here, 2 Dell laptops and asus too.

faelz commented 5 years ago

Same here. Video card nvidia.

yellowgh0st commented 5 years ago

@faelz which nvidia driver do you use?

Your issue could be something different. See also this: https://github.com/elementary/greeter/issues/166 Workaround could be this: https://github.com/elementary/greeter/issues/166#issuecomment-437144185

nvidia-340

yellowgh0st commented 5 years ago

@faelz As I mentioned It's a issue with driver provided in ubuntu repos.

otavioschwanck commented 5 years ago

I'm using AMD and have same issue. Not a driver related.

rodrigoyoshida commented 5 years ago

Same here, using two different laptops and both have the same issue. I have to lock and unlock my computers many times a day, so it is definitely an issue for my workflow. Both my computers have integrated and dedicated Nvidia cards. Tried the driver that came preinstalled and the ones from Nvidia. Still have this issue.

Is there anything I can do to help solve this issue? I really love ElementaryOS, I do not want to switch back to Ubuntu but this is affecting my work.

rodrigoyoshida commented 5 years ago

There is a pinned issue about this.

bbuhler commented 5 years ago

Copying my monitors.xml into lightdm config folder helped in my case.

sudo cp ~/.config/monitors.xml /var/lib/lightdm/.config
sudo chown lightdm:lightdm /var/lib/lightdm/.config/monitors.xml

sudo cp ~/.config/monitors.xml /var/lib/lightdm/.config
sudo chown lightdm:lightdm /var/lib/lightdm/.config/monitors.xml

It did not work in my case. I am considering switching back to Ubuntu since ElementaryOS feels a little abandoned about the support.

tdias25 commented 3 years ago

same here... nvidia gpu card too, i had this problem on my previous laptop also with a nvidia gpu

rreina commented 1 year ago

Hi, please see below for a workaround:

  1. Turn-on suspend when closing the lid in power settings: lid-closed-suspend
  2. Fully disable locking the screen in the security & privacy settings: locking-off-security

Result: your laptop suspends when closing the lid, hence saving power, and when your open it back you're logged in skipping the black screen bug.

There's a duplicated bug reported for Gala, here (#1126). However, Pantheon Greeter seems to cause this problem.
