NetworkManager disabled, KDE boots up slow

English Applications

Hi community,

Wow! openSUSE is not going easy on me.
This time, after booting up my system, all of a sudden KDE boots up slow, and I am unable to access my internet. System was working great before this happened. NetworkManager (now changed to a blue icon) detects no wireless connection, same with LAN.
I tried to run/re-enable **NetworkManager **from the terminal and it throws up this error:

** (process:4416): CRITICAL **: lookup_or_register_specialized: assertion 'specialized_types_is_initialized ()' failed

This same error was generated exactly 27 times. I also noticed KDE boots up significantly slower now.
Before this error, my immediate installations were Yakuake, python-gst & gstreamer-python (for running deepin music player).
Help, good Samaritans!

My laptop specs: oS 13.1, 64bit KDE (latest stable build), 4gb ram and a core-i3 m370 processor.

Update: Wired works after changing to **Traditional Method with ifup **in the Network Settings.
KDE is still booting slow and Wireless still doesn’t work.

You did not say what WIFI chip??

Hello,
Its an Atheros AR9285.
Do you know why this is happening?

Hi
When you installed python-gst, that was all that installed? If so you can probably remove it, since it wasn’t needed.

I think that wifi chip uses the ath9k module (check the output from lsmod).

You can analyse the booting via;


systemd-analyze blame
systemd-analyze critical-chain

Hello,
Yes the wifi chip uses that ath9k module.
I removed the gst-python package. I also ran both the commands like you advised, this was the output.
