Re: [Trisquel-users] Suspend / halt not working anymore after a Software Updater launch
Suspend/hibernate is often a problem with Linux (the kernel), and when it does/doesn't work seems to be hardware-specific. This is an issue in Ubuntu as well. Trisquel's kernel is created by running a script[1] which automatically removes the proprietary blobs from Ubuntu's kernel, so if this kernel version is indeed causing your problem it is not something that will get addressed on Trisquel's issue tracker. We need to keep troubleshooting on your hardware. There is some chance that the kernel is not the problem. To find out, try suspending and hibernating from a terminal. To suspend: $ sudo pm-suspend and to hibernate: $ sudo pm-hibernate See if either of those works and let us know.

I have already tried with different kernels: - the functionality with the 4.4.0-139-lowlatency release (and below) worked - the functionality with the 4.4.0-142-lowlatency release stopped working - the functionality with the 4.4.0-143-lowlatency release does not work neither

> like music artists working on computers, who often need a low latency actually, what does 'low latency' mean? :) I did not understand (but of course I thank you anyway for your comment). > Linux 4.4 was released in 2016. "hwe" stands for "HardWare Enablement". Those are packages providing more recent versions of packages that are important to support more recent hardware: like the kernel and the X server. Installing "linux-image-generic-hwe-8.0" actually provides what will be Trisquel 9's kernel, based on Linux 4.15, released last year. My hardware is older than 2016. PS : if I installed the 'low latency' kernel, it should have a reason (I am not a musician...) but nowadays I am not aware about it. Is there any more protection regarding private life with a "low latency" kernel?

Hello Magic Banana, Thank you for your detailled message! So: > You can boot the previous version of the kernel from the "Advanced options" (or whatever it is called), an entry in GRUB's menu (displayed before the operating system starts) I have booted to my previous system, which is 4.4.0-139-lowlatency > and confirm that the latest version of the 4.4 kernel is the problem. the suspend functionality worked fine > you could, of course, stick to that version, e.g., removing both "linux-image-4.4.0-142-lowlatency" and "linux-image-lowlatency" (and "linux-lowlatency", if installed). how can I remove my actual OS, which is 4.4.0-142-lowlatency? > However, not having an up-to-date kernel is security-wise, concerning. That is why, if I were you, I would install the latest 4.15 available in the repository, reboot, and see if suspend works. If you really want a "lowlatency" kernel (e.g., for music creation), but the way, what does lowlatency mean, is there any relation about music creation? > then install the "linux-lowlatency-hwe-8.0" package (in Trisquel's repository) what is linux-lowlatency-hwe-8.0, what are the differences? > Otherwise, install "linux-generic-hwe-8.0". why on my system, do I have only linux-lowlatency-[...] and not linux-generic-[...], is there any difference? Merci Magic Banana for your nice support :)
[Trisquel-users] Suspend / halt not working anymore after a Software Updater launch
Good afternoon, I have recently performed (like 5 days ago) a Software Updater launch, in order to update my Trisquel OS. $ cat /proc/version Linux version 4.4.0-142-lowlatency (jenk...@devel.trisquel.info) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.10) ) #168+8.0trisquel2 SMP PREEMPT Tue Feb 5 02:09:39 UTC 2019 $ The problem now is that my laptop get frozen after trying to suspend it or performing the command: shutdown -H Do you know how to resolve this annoying issue? Is the suspend functionality no more available from now on? Thank you for your kind support.
