NetworkManager-wait-online.service fails at boot and it delays my startup
I have a CEL-TEC F5A headset. The spec says:
Bluetooth 4.0, profiles: Headset, Hands free, A2DP, AVRCP/HSP/HFP
It plays nicely with High Fidelity Playback (A2DP sink) profile.
When I want to switch audio input to the headset's microphone, the output profile automatically changes to Headset Head Unit (HFS/HFP) and the quality is terrible - like 8bit sound or something. When I switch it back to A2DP, the input is back to desktop mic.
I've read few of other questions and seems A2DP is expected not to support input, right? But the HFP part in HFS/HFP is High Fidelity Playback I guess? That sounds like it could work as a headset and still not sound like 1950's phone.
How could I simplify switching between the profiles so that it is HFS/HFP when I talk and A2DP when I listen? E.g. as a push-to-talk.
Ubuntu 17.10, no sound customization IIRC, everything latest.

The problem here is not that the microphone does not work, but rather that the audio quality worsens when it is activated.
Countless times over the past few weeks I have been notified about the low battery in my wireless mouse. Every time it wakes up from sleeping mode and reconnects over Bluetooth I get a notification. I have gotten hundreds of notifications. I do not want them and I do not need them. Yes, battery is low, but at 0% (as reported) it will go on for another week at least. The notification has no timer and will stay visible until I close it.
How do I disable this torture?
Realizing I might sound like a grumpy old man I am not going to replace my batteries that are good for another month as a workaround. I am running Ubuntu 17.10 with GNOME Shell. I have no clue what is causing this. Pointers and suggestions will be greatly appreciated!
UPDATE: It turns out the mouse ran for another ten days or so after the initial notification. With the OS constantly reminding me that it will soon stop working. Wasting fine batteries is not a very good design. People should care about that and have an option to turn the notifications off.
UPDATE 2018-10-22: I asked some time ago. The marked correct answer might not apply anymore. It appears to be a bug in the gnome-settings-daemon
. See the report for updates revolving this issue.
I have an HP Pavilion 14 inch laptop.
I recently upgraded from Ubuntu 17.04 to 17.10.
Everything went well, but when I boot up the system, my screen rotation was set to left.
Then I tried using xandr to rotate my screen, but my every effort failed.
Can anybody help me on the same?
I have just upgraded to Ubuntu 17.10 and found out there is no option to have 2 by 2 workspaces. I was able to configure 4 "static" workspaces using GNOME Tweak Tool, but I would like to have them in 2 rows by 2. Any ideas?
