Bug#870641: light-locker: screen stays black after closing and opening laptop lid
Confirming fixed in Debian 10.5 point release: Bug is reproducible with kernel 4.19.0-9 running, not reproducible with 4.19.0-10 running. Tested via xdg-screensaver lock.
Bug#870641: light-locker: screen stays black after closing and opening laptop lid
Another weird thing: on 4.19.0-9, if I leave the screen/display off long enough, like: 1 lock the screen 2 see the display off 3 go out for lunch 4 when return, typing or moving mouse can bring the display back on. As comparison, if I leave the screen/display off not long enough, like going to take some drink, when I get back, in 4), the display won't be powered back on by typing or moving mouse. I have no idea of what happened...

I haven't I never tried suspend/hibernation before but I just gave it a shot. Interestingly, the display can be powered back on after resume even with 4.19.0-9 and I can then input my password and unlock the screen. My gut feeling is that, in the case of suspend/resume, the display is powered by the gpu dirver which is i915 in my case while in the normal lock/unlock case, the display is controlled by light-locker through some mechanism and the communication between light-locker and the gpu driver broke somehow. > had a chance to try Aaron Lu's suggestion of backported kernel 5.6.0.

It should include the fix. It doesn't seem easy to install packages from testing-proposed-updates. https://wiki.debian.org/TestingProposedUpdates doesn't tell me how to do that and after adding: deb http://some_debian_mirror/debian/ testing-proposed-updates main 'apt-cache search linux-image' doesn't show me linux-image-4.19.0-10-amd64..

Just want to report that I have installed 5.6.0-0.bpo.2-amd64 from buster-backport and now the display can be powered back on when I pressed my keyboard or moved my mouse. I do not see any other problems right now, everything seems to work fine, except one error message in dmesg everytime the display goes the off-on cycle: broken atomic modeset userspace detected, disabling atomic But I guess it's a different problem and it doesn't seem to cause any problem.

I've also re-pinged upstream Linux and the patch should be included in the next Linux point release (hopefully 4.19.123), and which will then be included in Debian buster for the next Debian point release (hopefully 10.5).

Maybe it changed from the Intel driver to the Modesetting one, or maybe the Modesetting gained (partial) support for atomics or something.

Bug#870641: light-locker: screen stays black after closing and opening laptop lid
I see I am coming to this thread a bit late, but for what it is worth, here is some additional information. But first, thanks to Udo Richter for suggesting the workaround of installing linux-image-5.4.0-0.bpo.2-amd64, in other words backporting the testing/bullseye kernel into buster. On my laptop, this fixed the intermittent problem restoring blanked screen. It also seems to have introduced a new problem where the computer occasionally does not blank or lock when it should, but that is far better than occasionally losing work-in-progress due to inability to restore the screen. However, this does not seem to simply be a case of buster's default 4.19.0 kernel being buggy. I say this, because I tried the backport version of 4.19.0 in stretch. On my laptop, screen blanking and locking work just fine in stretch, regardless whether it is the default 4.9.0 or the backported 4.19.0 kernel. Apparently, something besides the kernel changed between stretch and buster. Some background info: I have been testing with the xfce desktop on a Panasonic CF-19 laptop.

One more for the mix: I experience this behavior in most cases when light-locker kicks in as screen saver. Closing the lid or suspending never triggers this. i965 driver on Sandybridge CPU. Ctrl-Alt-F6-F7 brings me to a screen-is-locked display, and after some seconds, to the actual login prompt. Bug appeared after upgrading from stretch a few months ago. Debian/Buster, light-locker 1.8.0-3. I tried using the keys to change screen brightness, no effect.

Package: light-locker Version: 1.8.0-2 Followup-For: Bug #870641 Hi, I am experiencing this problem and I found a workaround ... If I lock the screen it goes black and won't unlock from the keyboard. If I ssh to the machine I can restart lightdm and get a login prompt. $ light-locker-command --lock (goes black, can't wakeup) If I create an Xorg config file that says to use the Intel driver it works. $ cat /etc/X11/xorg.conf.d/20-intel.conf Section "Device" Identifier"Intel Graphics" Driver"intel" EndSection Perusing the /var/log/Xorg.0.log finds that it was using the fbdev driver before. Here is the info on from my card. $ lspci -v [...] 00:02.0 VGA compatible controller: Intel Corporation HD Graphics 520 (rev 07) (prog-if 00 [VGA controller]) Subsystem: Lenovo Skylake GT2 [HD Graphics 520] Flags: bus master, fast devsel, latency 0, IRQ 126 Memory at f000 (64-bit, non-prefetchable) [size=16M] Memory at e000 (64-bit, prefetchable) [size=256M] I/O ports at e000 [size=64] [virtual] Expansion ROM at 000c [disabled] [size=128K] Capabilities: [40] Vendor Specific Information: Len=0c Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00 Capabilities: [ac] MSI: Enable+ Count=1/1 Maskable- 64bit- Capabilities: [d0] Power Management version 2 Capabilities: [100] Process Address Space ID (PASID) Capabilities: [200] Address Translation Service (ATS) Capabilities: [300] Page Request Interface (PRI) Kernel driver in use: i915 Kernel modules: i915 [...] If I can do anything else to help debug this issue, let me know. -- System Information: Debian Release: buster/sid APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'unstable'), (500, 'testing'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.18.0-2-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8), LANGUAGE=en_US.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages light-locker depends on: ii dconf-gsettings-backend [gsettings-backend] 0.30.0-1 ii libc62.27-6 ii libcairo21.16.0-1 ii libdbus-1-3 1.12.10-1 ii libdbus-glib-1-2 0.110-3 ii libglib2.0-0 2.58.1-2 ii libgtk-3-0 3.24.1-2 ii libpango-1.0-0 1.42.4-3 ii libpangocairo-1.0-0 1.42.4-3 ii libsystemd0 239-10 ii libx11-6 2:1.6.7-1 ii libxext6 2:1.3.3-1+b2 ii libxss1 1:1.2.3-1 ii lightdm 1.26.0-3 light-locker recommends no packages. light-locker suggests no packages. -- no debconf information
