 Posted: Sun Nov 06, 2016 9:50 pm Post subject: power management problem on Lenovo Carbon X1 4th gen |
 |
|
After installing the system a week ago, I cannot seem to fix the power management/suspend issue.
Symptoms:
s2ram works well at a root console (system properly goes to sleep and properly resumes)
s2ram does not work if I run it from su root in my X11 (I run a basic X11 installation started using startx with xmonad as the window manager). The only X11 applications I use are mate-terminal and chromium.
After leaving the system with X11 session on screen for a while, it goes into a power saving mode, from which it does not emerge properly (X11 dies and leaves a frozen console window behind, and only way to do anything then is to do a hard restart with the power button).
Closing laptop lid does not invoke a suspend mode, it simply had no effect.
It does not seem to make a difference whether I run laptop_mode (as described in https://wiki.gentoo.org/wiki/Power_management/Guide) or not.
Nothing seemingly interesting in dmesg or in other logs (I didn't try digging into laptop-mode options yet).
----------
In contrast, in Arch on the same machine I have a totally working suspend: I can just close the laptop lid and it goes into sleep, and resumes normally (I ran it for 1.5 months quite a lot, it never failed).
(I don't run systemd in Gentoo, it makes it a bit harder to dig up what's wrong...)
Basically, I'm at loss as where to even start. After more than 15 years of running Linux on laptops (more than a dozen of them IIRC), it's the 1st time I have it this bad...
Thanks,
Dima |

Duplicate your kernel.config,loaded modules and how you invoke that process from your ARCH installation.
I think you are missing some important kernel options. My guess: ACPI related, notebook related for your manufacturer. maybe some useflags missing.
Some kernel options are hidden and only show up when you enalbe those prerequisites. |

the kernel .config file is here:
http://users.ox.ac.uk/~coml0531/gentooconfig.txt
all looks meaningful... [/code] |

I found out that the lid case in /etc/acpi/default.sh was simply commented out!
I added
| Code: |
case "$action" in
....
lid)
case "$id" in
close) s2ram;;
open) :;;
*)uhd $*;;
esac;;
|
This at least made the machine going to sleep and wake up properly on lid close/open.
Perhaps a better way to accomplish this would be to add a script into /etc/acpi/actions/, but I have
no idea what and how.
Why lid case was commented out in the 1st place, I don't know. Perhaps cause it interfers with other, more usual, x11 setups? [/code] |

It seems it's down to DPMS not working properly.
Namely, the crash I describe is also triggered by running in xterm
the following:
xset dpms force off
I don't know how to fix it (short of disabling DPMS). |

| The problem went away after doing a full update (emerge ... @world) of the system just before the New Year. |
