If only Bluetooth worked...

Post by michaelzap » Sat May 12, 2018 1:39 pm

Been using and loving Mint for years. On my main laptop (a first-gen Dell XPS 13 - Core i5) I am running the latest Slylvia 64-bit with the MATE desktop. Been using it constantly and upgrading it for years and have rarely been tempted to switch to another distro, except for one nagging issue.

Bluetooth has never, ever worked for me on this laptop. I've researched it and tried every tutorial that folks have posted, but I can never get it to successfully pair with a mouse (which is all that I really want to do, and doesn't seem to be asking all that much). It detects the adapter and starts the process, etc., but it always fails.

At different times over the years (!) that I've struggled with this, I've just decided to wait it out and keep using a USB mouse. Maybe the next kernel or system update will resolve it, or maybe I'll buy a couple more USB mice and see if one of them works. But nope it never does.

Right now I'm at the airport beginning a trip and I just realized that I left my USB mouse behind. I had a fleeting thought that maybe I'd try again and buy yet another different bluetooth mouse and see if I could get that one to work. But... am I just being a sucker?

Has anyone here ever gotten a bluetooth mouse to work with a first-gen Dell XPS using the MATE desktop? If so, how? And what make/model of mouse are you using?

Thanks in advance for any help that folks can offer with this.

Hi michaelzap,

I just read your post and the good replies to it. Here are my thoughts on this as well.

It would help to know more about your system setup. If you run "inxi -Fxzd" and "lsusb" from the console terminal prompt, highlight the results, copy and paste them back here, that should provide enough information.

Which model XPS computer do you have? Don't these computers have a built-in touchpad and or touch screen?

If anyone here can help with your Bluetooth issues member "JeremyB" is one of them.

FYI: You can also get a tiny USB Bluetooth Dongle v4.x at very reasonable prices from Amazon.com, EBay, etc... which might work much better over using the built-in one, especially if the built-in Bluetooth adapter is a combination adapter. Search for "USB Bluetooth adapter linux" and read description and user comments.

I have one very similar to the ones below (csr 4.x) that work very well with my Bluetooth devices. I do not have a Bluetooth mouse or keyboard, but it works well with my Bluetooth headsets, clock radio, etc...

I have been using Microsoft® Wireless Mobile Mice for years.

1. I like little mice
2. these things are cheap as dirt
3. they work without specific drivers (OSX, Windows, Linux)

I have the first generation of non-touchscreen XPS 13s. This was before they sold these with Ubuntu on them, so I got it with Windows and then wiped it clean. I definitely don't want to use a USB dongle for bluetooth, since this laptop only has two USB ports and the main reason that I don't like to use a USB mouse now is because it means that I only have one port free.

I have a really nice Microsoft bluetooth mouse in a drawer back home that I would love to use someday, but it's one of the many that I could never get to pair with this rig.

I'm getting called to board, but I'll be interested to see what insight folks have when I get to LA in a few hours.

Thanks again!

Interesting!

When I use the firmware file that you provided (thanks!), I am able to pair with a Logitech M535 bluetooth mouse that I picked up at BestBuy this morning. So that's progress! However, it's completely unusable, since the pointer just sort of meanders around the screen lagging way behind my movements and sometimes not reacting to them at all. I can't accurately click on anything (I can't even pick out one Control Center icon if I really work at it) either. I tried turning off the trackpad entirely to see if that might be conflicting somehow (right now I just have it set to disable itself when I'm typing), but that only led to a fun game of trying to re-check the enable box with the bluetooth mouse that goes where it wants and registers clicks randomly.

Any idea what this new info might mean or how to resolve it?

My M557 Bluetooth mouse works normally with Cinnamon 17.2 on an old Elitebook 8730w. I have to re-connect to it every time I boot using the touchpad to make the connection, but outside of a double clicking left mouse botton, it works normally. - Mike

I'm now back from my trip and trying again to make this work (now with the mouse that I really want to work - a Microsoft Sculpt Touch mouse). There was a firmware update while I was away which I applied, and when I tried again to pair with this mouse, it failed (I also tried with another generic Microsoft bluetooth mouse, and it also failed to pair). So I copied the firmware that you linked to again and rebooted, removed the devices, rebooted, and tried again. Even with the firmware that you sent, my laptop is not discovering these mice at all (so of course, it's not able to pair with them). Ideas?
