    Thanks!

    There are plenty of windows help forums. Sorry, but i just refuse to try and fix what's inherently broken,
    CorrelatIon and faults are rarely connected in windows. Just as well that they tell you 0x11 11101010000011010101.

    OK, I switched back to Win10, and connected my router via an Ethernet cable. That gave me internet access. Then I unpluhgged it, and the WiFi Icon appeared and I can see multiple connections. I checked the Realtek RTL8723BE Wireless LAN 802.11n PCI-E NIC in Device Manager and tried to update the driver but it showed already up to date. Goofy!

    Last few days I spent probably 15 hours scanning 600 slides from 1970 to 1976, and as I did I saw that the "One Drive" sync was active and updating. But at one point it gave a warning that my 5 GB free OneDrive storage was full and it could not sync any more files. I tried removing some large files that I didn't really care about, but only freed up a few hundred MB. So I decided to stop syncing my "Pictures" folder, intending to back them up with an external USB drive. But when I did so, it seemed that the files on my hard drive were now gone! I was able to download them from One Drive, and then somehow it seemed that the files reappeared, but it's confusing, and the help page says that if you uncheck the Pictures folder, the files will be removed from your computer, but they can still be downloaded.

    That is very disturbing!

    BTW, I used a thing called ION Slides2PC, and it works pretty well, although the software is clunky. Many of the older slides are badly faded, but the software did a nice job of restoring color and proper brightness. It also helped to clean off almost 50 years of mildew. This is the first image in the roll, taken August 1970, before and after:

    This typically means that either the drivers have been disabled or the settings have been changed. Would Win10 do that to you? On occasion. Check your drivers to make sure that it's running one (and only one) that is compatible with your wireless chip and that it's properly configured.

    This is my laptop - only reason it is only 4 days is my battery went dead when I forgot to plug it in. Normally it is months..

The device manager in Windows shows a Realtek Bluetooth 4.0 adapter, and a Bluetooth device (RFCOMM protocol TDI). Also Microsoft Bluetooth Enumerator and Microsoft Bluetooth LE Enumerator.

    I really don't need Linux, anyway, but it was fun while it lasted. It also showed some instability. When the screen blanked and it went inactive, sometimes it would wake up showing the icons for the running apps in the left sidebar, but their windows would not open. I had to do a soft reboot, which saved the activity and restored the sessions, but sometimes it needed a hard power-off shutdown and restart.

    I took a video which I will post once I transfer it from my camera.
    That's that Gnome DE...

    Yup, try blueman if you want a gui.
    If your using ubuntu:
    sudo apt-get install blueman bluez-utils bluez bluetooth.
    Some broadcom chipsets aren't supported (like the one in my Asus tower).
    Good luck!

    I'm not familiar with that bluetoothctl and despise the gnome DE, but that's an aside.
    I'd use hcitool on the CLI and blueman-applet on desktop. Installing blueman-applet should pull all the required deps, then *just work*

    There may also be a button on the headset you need to push/hold to put it in pairing mode.

    I bought a bluetooth mouse around 2007... (yes 2007). I bought this for my dell xps running some form of ubuntu at the time. I don't really remember it working that great and I gave up on it. Fast forward to a few months ago. Got a MSI laptop with a clickpad. (boy do I hate click pads) blew the dust off of the V470 logitech 'laser mouse for laptops' and gave it a second try. Holy crap - it works way better (or I am smart enough to get it working decent now) Now I carry the laptop and the mouse where ever I go.

    I don't have any gui to setup the bluetooth devices - so I did it command line. 1 false start but got it working...

    used these directions - https://wiki.debian.org/BluetoothUser#Pairing_using_CLI and Using bluetoothctl

    The mouse has always worked - everytime I use the laptop. It has been awesome.

    As far as virtual machines - I use kvm/qemu...

    Short video on how I use it....

    Bluetooth functions flawlessly, with every device I've cared to try, on Debian. Since Ubuntu is downstream, I imagine it shouldn't be impossible to get working.

    I found that the Bluetooth headset also would not connect when running Windows 10. So I had to download and install the Toshiba drivers. Even then, it acted funny, finding my Dell Win8 laptop, and various names for the headset. Finally, after removing a USB disk drive (which was named a USB-serial bridge), the BT300 was displayed and installed.

    However, I am unable to find the device and connect in Ubuntu. I think I'll be sticking with Windows for most things now.

    I've been running Ubuntu Linux on my Toshiba Satellite for a couple weeks now, and I like it. I wanted to find a way to create GUI applications that run on this OS, and I found out that Lazarus (similar to Borland Delphi) can be installed and produce Linux executables. So I just made my first "Hello World" app. If you are running Linux, please try this and see if it works on your system. If so, this will be an easy way for me (or you, if you can code in Pascal) to perform various functions and develop unique applications.

    http://enginuitysystems.com/files/Linux1 (20 MB)

    I learned that in Linux, an ".exe" extension is not required.

    If you want to try Lazarus, you can obtain the files here:
    https://sourceforge.net/projects/lazarus/files/

    You must download and install three compressed files, and then the Lazarus application will appear in your installed software. Then just click to open the IDE, and add whatever components you wish. My simple application just has a line of text and a button that changes that text.

    The code (most of which is automatically generated):
    Code:
    unit Unit1;
    
    {$mode objfpc}{$H+}
    
    interface
    
    uses
      Classes, SysUtils, FileUtil, Forms, Controls, Graphics, Dialogs, StdCtrls;
    
    type
    
      { TForm1 }
    
      TForm1 = class(TForm)
        Button1: TButton;
        Label1: TLabel;
        procedure Button1Click(Sender: TObject);
      private
    
      public
    
      end;
    
    var
      Form1: TForm1;
    
    implementation
    
    {$R *.lfm}
    
    { TForm1 }
    
    procedure TForm1.Button1Click(Sender: TObject);
    begin
      Label1.Caption:= 'Hello World';
    end;
    
    end.

    I can download a copy of Windows 7: https://www.microsoft.com/en-us/soft...nload/windows7

    And VirtualBox: https://www.virtualbox.org/wiki/Linux_Downloads

    Now I am trying to get the Bluetooth on my Ubuntu machine to pair with some headphones I bought. They worked fine on my Win8 machine. Apparently BT is a known problem in Linux.
