[Bug 1301601] Re: [Dell Latitude E7440] suspend sometimes freezes when lock screen activates
After some research I found errors related to i915 module (see some output attached). I tried some kernel module parameters without success, but the solution that seems to work for me is disabling of SNA acceleration-backend following: https://wiki.archlinux.org/index.php/Intel_graphics#SNA_issues Would be great, if someone could confirm. ** Attachment added: "sleep_err_output.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1301601/+attachment/4397940/+files/sleep_err_output.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1301601 Title: [Dell Latitude E7440] suspend sometimes freezes when lock screen activates To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1301601/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I can confirm this bug on kernel 3.19.3-3 in arch linux using systemd and laptop-mode-tools. Workaround 2 helps in most cases but I still got freezes sometimes.

Both on Ubuntu and Windows For this matter, I have had success with WORKAROUND-2, and thus I am able to keep my lock screen on suspend. Not bullettproof, but I rarely get suspend hangs now. Do notice that since the time of this bug report, there have been several kernel updates, so that might also matter. To determine if that is the case, I'd have to run without any workarounds for a while and look out for new hang incidents. Have you experienced the suspend hang with the latest 14.04-kernel in -updates (kernel 3.13.0-36.63) ? Slightly off topic, but: Yeah, the current BIOS on this Dell model is obviously buggy. I did send a complaint to Dell support. The support case was closed after some dialogue (I ended up downgrading to BIOS A08), but I hope they forwarded the technical matters to the right people and that a future BIOS version will have more fixes for both keyboard, touchpad and suspend/resume.

[Bug 1301601] Re: [Dell Latitude E7440] suspend sometimes freezes when lock screen activates
Console switch workaround is reliable and prevents possible hangs on suspend when screen locking is enabled. It's implemented with a simple script in /etc/pm/sleep.d/99switch_to_vt1: #!/bin/sh # Possible workaround for bug: # https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1301601 # # Switch to a VT before suspending and back after resume case "$1" in resume|thaw) /bin/chvt 7 ;; suspend|hibernate) /bin/chvt 1 ;; esac ** Description changed: Closed lid, expecting laptop to suspend, but found it later hot, frozen and *not* suspended. (Airflow was not the best, since it was in a bag.)

[Bug 1301601] Re: [Dell Latitude E7440] suspend sometimes freezes when lock screen activates
Stalling suspend for a few seconds did not help. Now testing console switch workaround (switch to VT-1 at suspend, then switch back to VT-7 at resume.). So far this is looking better, and it might be preventing the hanging lock screen.

I feel certain now that this is somehow connected to lock screen, so I updated the bug title accordingly. Now on kernel 3.13.0-30-generic with the problem still present.
