Hi

Re: computer restarting after power down.

I've seen this on a Leonovo forum where someone was having similar problems with a couple of Leonovo's

Thanks for this. I disabled the Secure Boot before I installed Antix, and it has remained disabled ever since.
The other setting, or similar, does not feature.

Hi,

It's still worth loading Bios defaults...

Hi,

Klaas:
Try this

Create a file called testsuspend. Place the following into it and save it in your home directory.
Right click on the desktop and select "Create Launcher"
In "Name", call it Sleep .
To the right of "Command", click on the icon and browse to your home directoy. Click on "testsuspend" and then the "Open" button.
Now click on the "Create" button.

Double click on the new desktop icon named "Sleep" and click on the "Mark Executable" button in the "Untrusted application launcher"

Hey Bodge, that is exactly the sort of thing I was thinking bout in the absence of a button- telepathy ;-) This script works in that clicking on it makes the screen go black, but immediately afterwards it goes back to the desktop, this time with a prompt for the password.

Hi,

I've been looking at power states and suspend functionality on some of the kit I've got here or otherwise got access to.

Most of the time, it works flawlessly (different computers are using systemd suspend, pm-suspend or pm-suspend-hybrid).
What I did find, on two Linx 10 tablets (identical Mint 19.2 installations and firmware revisions) is that one worked with systemd suspend and the other didn't.
The only difference is the mainboard revision (one is rev 1.1 and the other rev. 1.2).

I cannot get the rev 1.2 Linx 10 to suspend by any mechanism in Mint 19.2 Xfce4. I'll retry later with Devuan and see if that works.

Hi,

Klaas: That's the exact behaviour I'm seeing with the Linx 10 tablet (Bay Trail SOC).

I'll look further..

Hi

Klaas:

dm-tool lock forces a login screen on return from suspend. If you want to, place a '#' at the beginning of the line to disable this part.

sudo echo -n mem | sudo tee /sys/power/state This is the effective "working part" of suspend. Other "stuff" is done by systemd.

Thanks for all that work !!

No, that does not do the trick, it still comes up with that prompt. I even deleted the "old" desktop shortcut and created a new one following the addition of the #, but to no avail, the password prompt reappears all the same.

what kernel parameters do you currently have in /etc/default/grub?

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nomux=1 i8042.reset=1 i8042.nopnp=1 rootdelay=5 acpi=force"

I think the reason this caused so much problems is the resume= was wrong.
add this to /etc/default/grub and rerun update-grub
another thought is maybe there is a bad configuration file in the home folder.
create a new user with adduser log into the new user and give it try.

Hi,

I'm looking at acpi interactions with various power managers.. Memory unloading is performed slightly differently on the Bay Trail kit.

Is Bay Trail relevant to my set-up?
