Hi All,
I have been facing issue regarding Bluetooth, which says 'no adapters available'. I have Realtek RTL8723DE for which I always have to install the wifi driver manually from here.
All packages are up-to-date.
Relevant info here.
Need guidance on how to approach for troubleshooting.
Thanks for this OS!
It is possible a tlp power saving misconfiguration is creating this problem.
Test to see if tlp is causing this by disabling tlp temporarily.
To prevent tlp from starting it can be masked:
sudo systemctl mask tlp && sudo systemctl mask tlp-sleep.service
Reboot, then test if the problem persists.
If there is no improvement by disabling tlp, then simply unmask tlp.
To re-enable tlp:
sudo systemctl unmask tlp && sudo systemctl unmask tlp-sleep.service
Then restart.
If the issue resolves with tlp disabled then you will need to decide if you want to leave tlp disabled. Masking tlp is not the preferred method to permanently disable tlp. It is best not to disable or uninstall tlp if this is a laptop as tlp is very important for proper laptop operation. On a desktop computer disabling or uninstalling tlp is probably of no real consequence. On a laptop TLP is important for managing power saving, fan speeds, battery charging, etc.
[rytesh@rytvish ~]$ systemctl status tlp
● tlp.service
Loaded: masked (Reason: Unit tlp.service is masked.)

[rytesh@rytvish ~]$ systemctl status tlp-sleep

Active: inactive (dead)
[rytesh@rytvish ~]$ uptime

Nope it's the same, I have unmasked the services. Is there any alternative driver?
Nothing helped so far, I have tried
However, after replacing the files the log has some different error:

One more thing is that lsmod shows the module but there is no configuration file for that module:
[rytvish ~]# lsmod | grep blue
bluetooth 675840 12 btrtl,btintel,btbcm,bnep,btusb
ecdh_generic 16384 1 bluetooth
rfkill 28672 9 hp_wmi,bluetooth,cfg80211
crc16 16384 2 bluetooth,ext4
[rytvish ~]# ls /etc/modprobe.d/
[rytvish ~]#
[rytvish 8723de]# find /sys/module/8723de/ -iname *.conf
[rytvish 8723de]#
I want to remove the already installed wifi driver and install rtlwifi_new but it keeps coming back after reboot, how to permanently remove it. Even i removed the directory from
/var/lib/dkms/
[rytvish ~]# modprobe -r 8723de
modprobe: FATAL: Module 8723de not found.
[rytvish ~]#
[rytvish ~]# rmmod -f 8723de

Hello,
I have the same problem on Ubuntu 19.04.
Did you find a solution of this problem?
I did numerous things nothing helped.
BUT the last week OS update resolved it by itself....
Fingers crossed 
until it happens again 
!
Now both Bluetooth and Wifi are working fine, running kernel is 5.4.2-1 Thank you All!
