Airplane mode on resume and no wireless
rishadfb opened this issue · comments
I've had this problem happen on my laptop (Asus ZenBook UX305FA) a few times now and I just recovered from it. If I leave my laptop lid shut overnight, it suspends and resumes correctly most of the time. Every once in a while (like just now), I open the laptop lid to find the suspend light indicator stabilize but the screen does not come on. When I reboot to my desktop environment (GNOME 3), it shows airplane mode enabled. When I disable it, my bluetooth appears but no wireless.
I tried all some settings in my BIOS to trigger my wireless to enable - toggling Fast Boot, CSM mode, Network Stack - but nothing worked. I uninstalled tlp and magically my wireless came back on. I'm somewhat familiar with the tlp configuration file, but in this case I'm not sure if it's a bug in the program, the driver or if there is some setting that needs to be changed.
I would really appreciate your help with this because this is a long time recurring issue. I'm not sure what log file output to provide, so please let me know if that would be helpful.
Hi,
TLP does not touch wifi on suspend/resume and has no configuration to do so.
What happens on suspend/resume with TLP uninstalled?
Please show the full output of
sudo tlp-stat

I still need your answer on my above question:
What happens on suspend/resume with TLP uninstalled?
Oh yes, sorry about that. Suspend/resume works normally with TLP uninstalled and wireless works fine. It usually works when TLP is installed as well, but sometimes when I resume (like today) the screen doesn't turn on and there is no response.
First of all your TLP installation is incomplete
**Warning: tlp.service is not enabled -- invoke "systemctl enable tlp.service" to correct this!
**Warning: tlp-sleep.service is not enabled -- invoke "systemctl enable tlp-sleep.service" to correct this!
TLP is neither invoked upon system start nor upon suspend/resume. Correct this with:
systemctl enable tlp.service
systemctl enable tlp-sleep.service
systemctl mask systemd-rfkill@.service
and check if the symptoms change.
If not, next try is to disable Runtime PM on battery
RUNTIME_PM_ON_AC=on
RUNTIME_PM_ON_BAT=on
Ok, thanks. I enabled the services and I will reply to this issue if there are any problems. I will close this issue for now.
There was no warning to run this command: systemctl mask systemd-rfkill@.service. Should that be something that tlp warns by default in addition to the other two services? The Arch wiki mentioned disabling rfkill which didn't seem to work for me. Does this command do the same thing?
There was no warning to run this command: systemctl mask systemd-rfkill@.service
Feature in v0.9. In Arch it's systemd-rfkill.service without the @.
I had this issue again right now and I tried everything. Finally I disabled Runtime PM on battery and it worked on reboot. Do you have some idea of what this means?
Buggy kernel driver (as always).
Instead of RUNTIME_PM_ON_BAT=on you may blacklist PCIe devices one by one in RUNTIME_PM_BLACKLIST= and re-check to isolate the offending device. Another option to test would be RUNTIME_PM_ALL=0.
