[Bug 1605813] Re: lock screen freezes while trying to wake from suspend
I'm experiencing this again, now without AC power (I think that was a red herring). It seems to be if I: - Reboot - Close the lid (which suspends the machine) - Reopen the list I've also noticed that certain things still render. If I plug/unplug the AC adapter, I will continue to see "battery charging/discharging" notification popups. Additionally, I had a log file open on the screen in VS Code. I changed the contents of this file from ctrl-alt-f1 virtual console, then switched back to my graphical session, and the displayed text in VS Code updated! But I still could not interact with anything on-screen, beyond moving the mouse (no mouseover animations, nothing happens when clicking with touchpad or mouse, no keyboard response). Attached dmesg output - session suspend/wake is the last ~60 lines. ** Attachment added: "dmesg output" https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1605813/+attachment/5360248/+files/dmesg-session-frozen -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1605813 Title: lock screen freezes while trying to wake from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1605813/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1605813] Re: lock screen freezes while trying to wake from suspend
I've just experienced this problem (or very similar) on a fresh install of Xubuntu 20.04, on a Thinkpad x240. On wake, I could move the mouse, and switch to a virtual console with ctrl-alt-f1. The session would sometimes animate for a moment (e.g. a notification about change in wifi), before freezing completely (except for mouse). I did not try killing/restarting any sessions. This happened both when selecting sleep then pressing the power button to wake, and when sleeping by closing the laptop lid and opening to wake. The laptop was plugged into AC power the entire time. The problem persisted across reboots, but stopped occurring (seemingly) when I rebooted, then unplugged the laptop from AC power. I can now wake successfully with the laptop both plugged and unplugged. Haven't tried rebooting again since. I have no proprietary drivers installed. `sudo lshw -C display`: *-display description: VGA compatible controller product: Haswell-ULT Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@:00:02.0 version: 0b width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:50 memory:e000-e03f memory:c000-dfff ioport:3000(size=64) memory:c-d Attached config files, which might contain relevant power manager settings. ** Attachment added: "The contents of ~/.config/xfce4/xfconf" https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1605813/+attachment/5360220/+files/xfconf.tar.gz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1605813 Title: lock screen freezes while trying to wake from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1605813/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I too was affected by this bug. I run a fully updated 16.04 installation (currently 16.04.2) of Ubuntu. I used nouveau. When I pressed the power button on my work desktop to wake it from suspend, *sometimes* (here I differ from the original reporter) the login screen would appear and freeze. The system would not completely lock up. I could use ctrl + alt + f2 to switch to TTY2 and then restart the computer, like the original reporter. If I tried restarting lightdm via sudo service lightdm restart, the computer would completely lock up and I had to perform a hard restart. I successfully worked around the issue by installing the proprietary nvidia driver (nvidia-340). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1605813 Title: lock screen freezes while trying to wake from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1605813/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Wow, that's a fast correction: for my laptop, the bug appeared yesterday, and was solved today! I am back to only one button "sleep" (under the three "logout", "reboot" or "shutdown" - sorry if the labels are not correct, these are raw translation of the French labels I get) which works, instead of the two ("sleep" and "deep sleep") which froze the laptop. Cool, thanks for the help. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1605813 Title: lock screen freezes while trying to wake from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1605813/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The same problem appears to me after upgrading to 16.04 with an Intel card (described below), both with sleep and deep sleep: when I wake the computer, I have a normal box in the centre of the screen, the rest is darker, and no login box... My only turn around is to log on another TTY, and stop the session (kill -9 -1). Similar environment otherwise (16.04.01 up to date, amd64), except fr_FR and graphic card. `sudo lshw -C display` returns (in French) *-display description: VGA compatible controller produit: 3rd Gen Core processor Graphics Controller fabriquant: Intel Corporation identifiant matériel: 2 information bus: pci@:00:02.0 version: 09 bits: 64 bits horloge: 33MHz fonctionnalités: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 ressources: irq:29 mémoire:f640-f67f mémoire:e000-efff portE/S:f000(taille=64) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1605813 Title: lock screen freezes while trying to wake from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1605813/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Another detail: I use xscreensaver, not Light Locker, which works perfectly well otherwise. And I get a normal sleep (from which I can wake the computer) when I undock my laptop (but I don't know why it turns to sleep mode in that situation). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1605813 Title: lock screen freezes while trying to wake from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1605813/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
