[Kernel-packages] [Bug 1801743] Re: Suspend fails in Kubuntu 18.04 but works fine in Kubuntu 17.10
I have the same issue. Unfortunately it's now Ubuntu 20.04 and kernel 5.4.0 and it still happens. My laptop is Lenovo Thinkpad T440p. First issue that was happening all the time was that the touchpad didn't work after waking from suspend. But it was better known issue with some fixes with the help of some scripts. This is harder as it's now happening always but only sometimes and I haven't figured out robust steps to reproduce this issue. It just happens sporadically but when it happens only hard reset helps. My laptop has also Intel CPU and nVidia graphics card so that's something that is common I suppose. If anything else is needed I could provide more information. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1801743 Title: Suspend fails in Kubuntu 18.04 but works fine in Kubuntu 17.10 Status in linux package in Ubuntu: Confirmed Bug description: After upgrading to kubuntu 18.04 resuming from suspend fails in most cases on my laptop.

Felipe, can you try to cancel the lid option? you do it with sudo sh -c "echo LID0 disabled > /proc/acpi/wakeup" than check it is '*disabled' in the LID0 entry, by running cat /proc/acpi/wakeup and check the output. You can close the lid and it will sleep, but it will not wakeup when you open the lid, only when you press the power button to start it.

Thanks for this, nadi! I applied your fix using a systemd service, and upon boot /proc/acpi/wakeup now reports LID0 as disabled. Unfortunately, it still does not work.

I updated the BIOS but it did not help but I SOLVED my problem, and perhaps yours as well Magnus! The problem was with the LID upon waking up from sleep S3. I found it after hours of googling and eventually debugging using this link: https://01.org/blogs/rzhang/2015/best-practice-debug-linux-suspend/hibernate-issues I cancelled the ACPI that enables the lid: echo LID0 > /proc/acpi/wakeup which turns the disabels the lid signal to the ACPI. It is problably doing something wrong, I will try to file a new bug soon. This is the relevant output of the wakeup file: XHC S0*enabled pci::00:14.0 XDCI S4*disabled HDAS S4*disabled pci::00:1f.3 LID0 S3*disabled platform:PNP0C0D:00 PBTN S3*enabled platform:PNP0C0C:00 Every boot I have to re-disable it, so I make a small script and used crontab -e, and added the this line to the end of the script: @reboot /usr/local/bin/myFixScript.sh see the link https://www.kompulsa.com/run-a-program-on-startup-console-on-ubuntu-18-04/ Lets see how long it will be stable :-) Cheers...

[Kernel-packages] [Bug 1801743] Re: Suspend fails in Kubuntu 18.04 but works fine in Kubuntu 17.10
OK, I think I progressed a bit: SUPER STRANGELY, awaking from sleep crashes only when I close the lid. My Dell latitude has Fn-sleep combo so I can suspend the laptop from the jeyboard, and then I have no crash. I tried several times and it repeatedly wakes up without problems. BUT if I close the lid after the suspend (also when I suspend from the keyboard Fn combination), the laptop crashes when tries to wake. I can reproduce this. Googling around, I did not find any solution in linux, but several had the same problem in Windows: https://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/workstation-crashes-sometimes-when-lid-is-closed/2c3c38a7-dee7-4ee8-a233-a5031f59110c Which microsoft suggest waking USB driver, perhaps it is Intel USB 3.0 driver.

Hei Nadi, sorry, that was rather vague. Yes, by that I mean that it does wake up from sleep, and it does wake up immediately when I open the lid. When using 4.15.0-36 or later, on the other hand, sleep is not reliable. It may work, but most times it does not.

[Kernel-packages] [Bug 1801743] Re: Suspend fails in Kubuntu 18.04 but works fine in Kubuntu 17.10
Hei, I have the same problem as Carsten Gräser (graeser), and in fact a similar laptop (Dell Latitude 7390). I tried all the possible kernels since 4.14 to 4.19, and suspend (sleep S3) does not work. Same symptoms: It suspends when I close the lid, but cannot resume. When I open the lid and press the power button, it flushes ones but the screen is black. No response, no mouse, all dead. The only solution is to press again on the power button which performs hard reset. Important comment: when I suspend from the function key (Fn-suspend) it works, but only for a short time (less than a minute): after some time (I did not manage to find out exactly how many minutes) it cannot resume. When I close the lid, it fails compelety does not matter how long I wait. Strange!

[Kernel-packages] [Bug 1801743] Re: Suspend fails in Kubuntu 18.04 but works fine in Kubuntu 17.10
Unfortunately, not for me. We have a bunch of (theoretically) identical computers in a new classroom, and on one of them this issue is present. Similarly as described by Carsten Gräser (graeser): last entry in kern.log, running fan and no reaction to either keyboard or power button, last message on screen being A start job is running for Hold until boot process finishes up (21s / no limit). Only the power button is blinking, not steady, and with addition of similar problems at the shutdown (NOT at the reboot, except for the long delay). It seems that the system thinks from certain gauges that it is suspended or powered down, but some part of it is not. Last message for the failed shutdown is reboot: Power down and then everything stays as if there would be the classic message "It's now safe to power off Your computer", with screen on and fan running. To reinstate, installing the upstream kernel 4.19.1 did not help on this issue. Some 30 PCs of identical hardware do not have this problem. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1801743 Title: Suspend fails in Kubuntu 18.04 but works fine in Kubuntu 17.10 Status in linux package in Ubuntu: Confirmed Bug description: After upgrading to kubuntu 18.04 resuming from suspend fails in most cases on my laptop.

Yes the issue did not happen prior to the update to 18.04. But I don't know if there was a prior kernel in 18.04 where the issue did not occur, because it's not happening 100% of the time. Still a successful resume is rare.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.19 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
