I have a Bluetooth 4 LE Ortho Remote by Teenage Engineering for controlling media. When attempting to pair with a Lenovo ThinkPad P14s, the device is seen in the list of available devices, but when clicked, immediately refreshes the list and fails to connect.

I have a Schiit Fulla 3 that I've used on a ThinkPad e480 with Ubuntu 20.04 for several weeks now without issue. Yesterday, the device was no longer showing up in sound settings as an input or output choice. When I lsusb with it not plugged in, I get:

user@e480:~$ sudo lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 006: ID 06cb:00a2 Synaptics, Inc.

Bus 001 Device 014: ID 0bda:b023 Realtek Semiconductor Corp. Bluetooth Radio 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

and when I plug it in, I get:

user@e480:~$ sudo lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 006: ID 06cb:00a2 Synaptics, Inc.

Bus 001 Device 016: ID 30be:0100 Schiit Audio I'm Fulla Schiit
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

so I know it's detected... Other than semi-regular apt updates, I haven't changed anything config-wise. It also isn't showing up in the pacmd list-sinks list.

user@e480:~$ pacmd list-sinks | grep -e 'name:' -e 'index:'
  * index: 0
    name: <alsa_output.usb-Ingenic_Semiconductor_CO.__LTD._HD_USB_Camera_Ucamera001-02.mono-fallback>
    index: 1
    name: <alsa_output.usb-Blue_Microphones_Yeti_Nano_8918B12148040506-00.analog-stereo>
    index: 2
    name: <alsa_output.pci-0000_00_1f.3.analog-stereo>

Where should I look next to find out why it's not a choice?

I have a Blue Yeti Nano that includes a hardware mute switch. Blue's Sherpa desktop software is able to detect mute state and pickup pattern over USB. Is there a way to detect this via shell script on Ubuntu? I am looking to trigger a script to run when the mute state is toggled.

The official documentation for xscreensaver gives an example of how to play videos as a screensaver:

Install mpv and add something like the following to the `programs' preference in your .xscreensaver file:

 "My Movie"  mpv --really-quiet --no-audio --fs --loop=inf  \
                 --no-stop-screensaver                      \
                 --wid=$XSCREENSAVER_WINDOW                 \
                 $HOME/movies/*.mp4                       \n\

That's all well and good, but I would love to have one less dependency on my system (namely, mpv). I'd like to do the same thing, but with VLC.

I've tried adding this to my .xscreensaver file:

"My Movie"  vlc -L -R -f --intf dummy --no-video-title-show  \
                        $HOME/movies/*.mp4                 \n\

This command works perfectly on the command line, but when launched via xscreensaver, this happens:

^{Sorry for the blurrycam, I couldn't take a screenshot without exiting the screensaver!}

What do you mean, unknown option or missing mandatory argument '--intf'?! It's right there!

Does anyone know why I can't get this VLC command to run via xscreensaver, when it works perfectly when launched straight-up on the command line?

After installing Ubuntu 10.10, the battery indicator worked fine (both percent remaining and estimation on time). I then installed and configured some software (Skype, Pidgin, Thunderbird, removed Empathy and Evolution, ect) and the battery meter, when clicked, always says "(estimating...)"

I've tried running the battery down to zero and charging it fully again. If I go into the history or details, the percentage is recorded correctly.

Any ideas?

I'm not a particular fan of Ubuntu Netbook Remix, but the one feature I miss is the ability for a window taller than the vertical pixel length exists, it automatically adds a scrollbar.

Can I add this UI tweak to the standard version of Ubuntu? I can't see half of my Okay buttons in settings screens!

Ralink Technology publishes their drivers in source code form on their website here. When complied with make and make install in 10.04, the drivers worked well in 32 and 64 bit versions of Lucid. However, when compiled for the 64 bit version of Maverick, it does not work at all, and 32 bit Maverick, it works but randomly disconnects.

Both versions of Maverick say "[Proprietary] Driver is activated but not in use" in the Proprietary Drivers dialog.

Do the drivers just need to be updated? Is there an easy fix?
