Questions[lxqt](ubuntu)

I use Lubuntu 19.04 with LXQT on a notebook with a 15-inch display and a Full HD (1920x1080 px) resolution. I set the scaling of the display to 120 by .Xresources file in the Home directory. The cursor is not terribly small, but it's size is still annoyingly smaller than what I use in Windows.

Under the LXDE desktop environment I had a way to manage the size of the mouse cursor, but now - not. I have tried my old methods plus a couple of others already with no success yet.

So I just would like to know if there exists any way to manage it's size. I think it is logical such a way to exist, since we can see that the cursor appears in a certain size anyway - this should mean that there is a setting for that somewhere.

My system shuts down when I push te power button instead of suspending like most laptops. There are many complex forum solutions for that on the net, but I like to solve it with this command:

"gsettings set org.gnome.settings-daemon.plugins.power button-power suspend;"

The only problem is lubuntu uses LXQt now, so the result is: No such schema “org.gnome.settings-daemon.plugins.power”...

My question, what would be the equilavent gsettings command for lubuntu 18.10? Thanks for any idea's offered.

I use LXQT in Lubuntu 18.10 and I have a problem with keeping the Bluetooth-speaker connected to the laptop after logging out and in. It works fine after reboot though.

So, I have a solution that always works: rebooting - OR: reinstalling bluez:

sudo apt-get install --reinstall bluez

and that always works!

In any case, when my problem happens, the bluetooth is never blocked.

If I reboot or reinstall bluez there is no need to remove and add again the device, setting it to "Audio sink" is enough.

When this happens, after logging out and in:

• The speaker is listed by blueman-manager, setting to 'Audio Sink' brings the error Protocol Not available.

In terminal:

• But the problem is not the same as Bluetooth - Connection Failed: blueman.bluez.errors.DBusFailedError: Protocol Not available, because pulseaudio-module-bluetooth is already installed.

and

~$ pactl load-module module-bluetooth-discover
Failure: Module initialization failed

because it was already loaded.

Removing the device and trying to add it again: it is not found at all!

Which aspect in the normal operation of bluez - one that is available at system startup as well as by reinstalling the package - could be lost by restarting the session? - And how to avoid that loss?

UPDATE/EDIT by the OP:

[I am the OP. At some point I have deleted my account and then I came back with the same id.] I want to add that this is a Lubuntu-LXQt-specific problem. I have seen this problem in many Ubuntu and Ubuntu-based distros before 18.04, but in none since 18.x. Since 18.04 it is fixed excepting in Lubuntu-LXQt.

Details of the bluetooth adapter:

lsusb | grep Bluetooth
Bus 001 Device 013: ID 0489:e00f Foxconn / Hon Hai Foxconn T77H114 BCM2070 [Single-Chip Bluetooth 2.1 + EDR Adapter]

I try to add a quicklaunch item to the panel in Lubuntu 18.10. This seems only to work with drag and drop from the start menu and not via a menu for the panel setting.

Since Lubuntu changes its desktop from LXDE to LXQt there have been changes in icons of the panel and PCmanFM, the file manager. I am not an experienced user but I am wondering why a change in technology also has to come with changes in the look and feel of the desktop environment.

Especially when Lubuntu 18.10 is also using PCmanFM (qt version) I don't understand why PCmanFM does not simply look as clean as it did in 18.04.

Is there a way to use settings, e.g. openbox configuration manager or others, to make the new Lubuntu look like the last one(s)?
