Bluetooth is not enabled on startup, every time I want to use it, I first have to run those commands in the terminal:
sudo rfkill unblock all
sudo hciconfig hci0 down
sudo rmmod btusb
sudo modprobe btusb
It does the trick, but is there any way to enable Bluetooth right from the get-go?
Can you help me copy files on my Walkman device. I have Kubuntu 23.10. I inserted Walkman (Sony) in my USB port and it detected very well, but when I try to copy files in Walkman and type in console:
sudo cp "file.mp3" /media/user/WALKMAN
it is showing:
cp: cannot create regular file '/media/user/WALKMAN/file.mp3': Read-only file system
I installed gmtp, but it showed:
Detect: No raw devices found
How do I can get full access to my Walkman?
I currently have my laptop (ubuntu 24.04) plugged into an ethernet connection. In Settings/Wi-Fi, I have it set NOT to auto connect to my local wi-fi. If I click "Turn on Wi-Fi Hotspot", the hotspot comes up, the dialog shows a QR code for connecting, and the hotspot has a name which matches my machine name (lets call that my-sys). If I look at my phone, I see a connection for my-sys and can connect to it.
I can turn that connection on and off from the command line using:
nmcli con up Hotspot
nmcli con down Hotspot
If I try
nmcli con up my-sys
it says "unknown connection my-sys"
ok so far, although a bit confusing. If I try to set up a separate wi-fi connection name:
nmcli con add type wifi ifname "wlp170s0" con-name "my-hotspot" autoconnect no ssid "my-hotspot"
nmcli con modify "my-hotspot" 802-11-wireless.mode ap ipv4.method shared
nmcli con modify "my-hotspot" wifi-sec-key-mgmt wpa-psk
nmcli con modify "my-hotspot" wifi-sec.psk "my-pw"
nmcli con up "my-hotspot"
The connection appears to come up:
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/35)
If the Settings/Wi-Fi window is showing, the hotspot active QR code shows with the disconnect button, and "my-hotspot" shows as the network name, etc. However, there is no signal (no bars on my phone), and my phone does not see the network.
If I do "nmcli con show my-hotspot" and compare that with the results of the default Hotspot started from the Settings screen, there are two main differences. First, the default Hotspot has 3 sets of parameters listed, while my-hotspot has only one set. Second, the only thing that stands out are these three lines:
my-hotspot Hotspot

802-11-wireliss-security.group: -- ccmp
I tried setting those and it made no difference.

i reinstalled ubuntu on my pc. Now I have a problem with the terminal. When I call cmake --build . I get no output in the terminal only if I run cmake --build . 2>&1 .
Other commands like ls are working just fine. But from Julia I also get no output.
Im using oh my zsh, but with bash I had the same issue.

This was the only part with /dev/null in my .bashrc. The PC is on my workplace. I only connect with ssh. Tryed with "normal" terminal and vscode. No difference.
After I did a update of my Ubuntu 25.10 the wifi stopped working. I have tried reinstalling but when I did a update the wifi stopped working again. I am using TPM encryption on my disk.
The PC is a Dell Precision 7680.
I found that sudo dmesg | grep wifi shows
[ 9.903015] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-so-a0-gf-a0-89.ucode failed with error -2

[ 9.911118] iwlwifi 0000:00:14.3: check git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
So the iwlwifi-so-a0-gf-a0-89 is missing and I guess this should be part of linux-firmware.
When I do sudo apt install linux-firmware I get

How can I solve this dependency error ?
I have tried reinstalling again and the wifi works in the installer but once I boot the installed OS it stops working.

I am using Ubuntu 20.04 with Cronopete 4.13.0 as my backup software. This has worked without issue for a number of years. I have 485GB of space left of 984GB on my backup hard drive.

I made a program that communicates with my headphones through HID, but I can only run it with sudo. I tried changing the device access rules to 0660, 0666, and other values recommended online by creating a new udev rule and adding it to plugdev (since my user is in that group).
I also tried making it accessible to everyone and directly to my user, but nothing worked. The permissions look correct, yet it still requires sudo to run.
When I plug in the device, these show up. I only use one interface, but in the end I tried moding all of them just to be sure:
/dev/hidraw9
/dev/hidraw10
/dev/hidraw11
When I check permissions, it looks fine:
crw-rw---- 1 root plugdev
This is the new rule I tried (without specifying the interface at the endt, to match all):
SUBSYSTEM=="hidraw", ATTRS{idVendor}=="1038", ATTRS{idProduct}=="2232", ATTRS{bInterfaceNumber}=="03", MODE="0660", GROUP="plugdev"
I tried both restarting the system and running:
sudo udevadm control --reload
sudo udevadm trigger
But it did not work.
Error:
# python
import hid
...
shome_device.open_path(the_path) # -> open failed
...
When I run it with sudo, everything works correctly and as expected.

I'm using Ubuntu 24.04 and I'm encrypting all my documents via Cryptomator to upload them to a cloud service. The HDD is formated in NTFS.
The problem is that when I try to access those documents in the mounted unit or vault, I can't open either Word or Excel files, or even listen to audio documents. For example, VLC gives me the following error: "VLC is unable to open the MRL" and LibreOffice Calc shows me this error when I try to open documents: "Acces to "XXX" was denied". I've checked the permissions and they look good, actually I can modify .txt files with the Ubuntu text editor and it gives no error.
This is a problem since I cannot open my documents directly on the vault so they are are not synchronized automatically after modifying them. I have to open them in the Desktop (for instance), modify them, and then copy and paste them to the crypto vault.
Thank you in advance.
Recently (likely due to an upgrade but not due to a reboot), my system stopped letting me ping other hosts, though root can do so just fine. It provides an informative error message, but it wasn't quite informative enough for me:

I used to have another version of Ubuntu on my old MacBook Pro and one day WiFi disappeared with the "No Wi-Fi Adapter Found" in the Settings. I tried to follow various options found on different forums, but it didn't help. I installed Ubuntu 22.04, but the problem is still the same.

I'm trying to connect an Xbox One controller to my Ubuntu machine. What happens when I try to pair it over Bluetooth this:
The problem is, even though it shows as connected in Ubuntu, the light on the controller doesn't stop flashing and it's not recognized in HTML5 games.
Can anyone advise?

I'm quite new to Linux, and have been trying this client to sync OneDrive files. It initially works for personal files, but not for shared folders. I believe I need to configure this functionality as per
https://github.com/abraunegg/onedrive/blob/master/docs/BusinessSharedFolders.md
However, I find this step hard to understand:
Configuring OneDrive Business Shared Folders
[alex@centos7full onedrive]$ cat ~/.config/onedrive/business_shared_folders
# comment
Child Shared Folder
# Another comment
Top Level to Share
[alex@centos7full onedrive]$
I created a text file 'business_shared_folders' inside .config, but I can't figure out what "Child Shared Folder" and "Top Level to Share" mean, neither what I should write in "[alex@centos7full onedrive]" (maybe exactly as it appears in the terminal before '$'?). Sorry if the question is too basic.
I tried other clients such as Onedriver, but couldn't find instructions about how to configure it to cync shared folders from Business.
I have been trying to install a software called ABAQUS on my UBUNTU laptop and as a part of the installation, I'm trying to run a script file called 'StartGUI.sh' using the command "bash ./StartGUI.sh" in the terminal. It then shows the following error every time: "Error: This media has been unzipped or copied in such a way that the permissions of some files have been lost. Please unzip or copy the media again."
I have tried selecting all the files and gave read and write permissions, yet I am facing the same issue. When I looked for a solution in Google, some articles suggested using 'chmod' but I couldn't figure out how to use it exactly. Could you guys please help?

Windows 10 has a feature to enter BIOS/UEFI directly from the OS, which is handy for machines that do not allow you to enter them during startup.
I would like to install Ubuntu on an OEM device and obviously I will be using the Windows feature to do this, but I will still require BIOS access in the future.
How can I access the BIOS from Ubuntu?

I recently installed Ubuntu 16.04 (64-bit) alongside Windows 10 on my laptop. It picked up my Intel integrated graphics just fine, but my AMD graphics card does not appear at all in Additional Drivers. Although Ubuntu works fine without using my AMD card at all, I get pretty poor battery life. Any ideas how to fix this problem?
Additional info: My computer is a Toshiba L50-B025D with an AMD Radeon R7 M260 graphics card.
appstreamcli is overheating my laptop by constantly using 100% of a core. My only solution is to kill it. Here's a screenshot of top:
I can kill appstreamcli with either sudo kill pid or sudo killall appstreamcli. But once I do sudo apt update, the appstreamcli process returns again and hangs the update. If I then kill it, I get the following output:
Reading package lists... Done
E: Problem executing scripts APT::Update::Post-Invoke-Success
'if /usr/bin/test -w /var/cache/app-info -a -e /usr/bin/appstreamcli;
then appstreamcli refresh > /dev/null;
fi'
E: Sub-process returned an error code
What is this process and why is it using so much CPU?
I'm running Ubuntu 14.04 LTS and updated my graphics card to Nvidia Quadro K4200 in order to get stereo capability. It worked with the recommended Ubuntu driver (nvidia-352), although I struggled to get stereo working, so I installed the latest Nvidia driver (361.42). To do this, I got a terminal with
Alt-Ctrl-F1
stopped X with
sudo service lightdm stop
and then ran the install script from NVIDIA. When I restarted X with
sudo service lightdm start
I got a black screen with a blinking cursor in the top left of the screen and Alt-Ctrl-F[1-6] did not give a terminal login. My only option is a hard shutdown (holding down the start button) and when I reboot it returns to the black screen.
I saw this post which looks the closest to my problem that I found, with a solution that requires Alt-Ctrl-F1 which isn't giving me a terminal login option. Any suggestions are very much appreciated.
I have a multi-page pdf file, and I want to rotate a specific page 90 degrees clockwise, to obtain a new pdf file which has the same pages as the original pdf, but with this specific page rotated. How can I do this?
Is there a keyboard key combination that I can use to pause a program running in the terminal? In case it matters, I don't intend to run anything else inside that terminal while the program is paused. I just want to pause the program execution, and resume it later. How can I do this?
I'm banging my head over this for past 4 hours, and I cannot crack it! Google turns out allot of issues related to SASL authentication failure: Password verification failed but none helped.

I would like to record a stereo mix (basically what I hear through the speakers connected to my sound card) from VLC. However, I haven't been able to figure out exactly how to do this.
Under the "video4linux" capture device, I see the following audio devices:
hw:0,0
hw:0,6
However, selecting either of those results in VLC trying to use my webcam (not what I want at all) in addition to the selected audio device.
What do I need to do?
I typically have two needs:
Scenario A. Change a single PDF page.
In this case I have a PDF but not the original source file used to create the PDF. I don't want to try to recreate the document from scratch. I'd like to open the PDF and change a few things. A good example of this scenario: I was responsible for planning a big event at a campground site, I had a PDF of the site. I wanted to start with that document, highlight some parts, add some labels, remove some parts that weren't relevant.
or
Scenario B. Combine PDFs or extract page(s) from a PDF
This scenario usually arises because I want a single PDF deliverable that is made up of parts that are best created in different programs. In this case I have the source files for all the documents but they don't play well enough together to easily create a single PDF deliverable. For part of it, I may want to use Libre Office Writer. For another page I may want to use Gimp. Still another page I may use Libre Office Calc. I could use Writer as the master document and embed images or the Calc object into that, but for ultimate control, you can't beat separate PDF documents that are then combined.
What are the best tools / processes for editing PDFs in Ubuntu?
