[Kernel-packages] [Bug 1801743] Re: Suspend fails in Kubuntu 18.04 but works fine in Kubuntu 17.10
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. Let me know if it works for you. -- 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.

[Kernel-packages] [Bug 1801743] Re: Suspend fails in Kubuntu 18.04 but works fine in Kubuntu 17.10
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. I will update the BIOS and if the problem persists, I will open a new bug report. -- 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.

[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! Currently using Linux version 4.19.7-041907-generic (kernel@kathleen) (gcc version 8.2.0 (Ubuntu 8.2.0-10ubuntu1)) #201812052010 SMP Wed Dec 5 20:11:58 UTC 2018 Tried 18.04 and than upgraded to 18.10, still the same problem.

When trying to resume the power LED is turned on, but the screen stays black and the system does not respond at all. Switching to another virtual terminal is not possible and closing the lid again does not show any effect. The hardware is a Dell Latitude e7440 with core i7 4600U and intel graphics only. The only way to change the status is a hard shut-down by long pressing the power button. The last message in kern.log is: PM: suspend entry (deep) The described problem is similar to bug #1774950. However, the latter is considered to be fixed with kernel 4.15.0-38 while my problem persists with this kernel.
