Hello fellow lemmings

I am a long-time i3 user and have decided to switch to Sway. I have encountered a weird error which has left me utterly bamboozled.

I am using Ubuntu 24.04 which has gone from 20.04 -> 22.04 -> 24.04. It has Ubuntu-Gnome, i3 and Sway currently installed.

The issue

The error that I'm facing is when I'm using Sway, I simply don't have sudo access.

This is what the error looks like

 undefined

    
$ sudo visudo
[sudo] password for xavier666:
Sorry, user xavier666 is not allowed to execute '/usr/sbin/visudo' as root on <HOSTNAME>.

  

When I switch back to i3, my permissions are fine for the same user. I have not done any crazy modifications to the sudoer's file as far as I can remember.

PS: I have added a command to no-sudo xavier666 ALL = NOPASSWD: /usr/bin/brightnessctl

The "fix"

I temporarily solved it by adding xavier666 ALL=(ALL:ALL) ALL to the sudoer's file.

IMO, I think this should not be required. I don't remember ever adding the default use

I switched to a Linux Mint/Win11 dual boot system over the weekend and installed Unity from Flathub. Running Unity Hub is fine but when I try to login, it hangs with no errors. I can log into the asset store just fine, so nothing wrong with the credentials. I'd like to know what terminal commands I could use to see what it's actually doing and figure out why it hangs.

I really don't want to continue using it in Windows and only keep it to run work programs, and really need to use Unity for University.

Edit: Troubleshooted via the terminal, then uninstalled the .Deb package that I downloaded from the Unity website and then followed another tutorial from another part of their website with terminal commands. Managed to log in and run my projects.

I want to install voidlinux. So I partitioned disk using cfdisk, but void-installer(and lsblk) show me different results. lsblk tells me that I have 4 partition, when cfdisk tells me only about 3. These partitions also have different sizes.

Hi!

I'm a new Linux user, so far so good, but one thing that grinds my gears is that if I log in fairly quickly after a boot, I have to wait ~5-10 seconds before I can start using my BT mouse (Logitech MX Master 3S).

Is there a way to speed up the initialisation of Bluetooth on Linux so that it starts immediately, like the USB drivers do?

Solution

Thanks to /u/floofly on r/linux4noobs for this!

Yup, assuming you're using systemd as you innit system. The following will change it so your bucktooth will initialise before the GUI.

sudo systemctl edit bluetooth.service

change:

    Before=graphical.target

  

And from myself, I'll add this for the other noobs out there: when you run

Solution: When I formatted all my drives to install Linux on one and Windows on the other, I kept both connected and they share EFI boot partition as a result. Every time I reinstall Linux it formats the drive and therefore deletes the Windows's EFI Boot as well. One way is to fix this is to reinstall Windows while disconnecting the drive you have Linux on. Or you can move the boot files if you don't want to do that.

I used this guide: https://forums.tomshardware.com/threads/changing-windows-boot-manager-drive.3571420/post-21561626

Also remember to delete the Microsoft folder in the boot folder on Linux after you’ve checked that the new boot loader is working.

OP:

Currently dual booting as I need Windows for a few tasks and ganes Linux just won’t do. Since setting everything up I’ve reinstalled Linux twice, both times I’ve lost the ability to boot into windows and have needed to reinstall it.

Disk doesn’t show at all in Grub, tried al

My laptop does support this feature since it was working on Fedora KDE. But jumping over to arch, it seems not to work at all.

EDIT: The bad solution is to unblock UDP port 5353 but the port has to be source port, not destination port. (--sport flag) See the now modified rules. The issue is that this is very insecure (see this stackexchange question and comments) but obviously better than no firewall at all because at least I'm blocking TCP traffic.

The proper solution (other than using glibc and installing nss-mdns package) is to open a port with netcat (nc) in the background (using &) and then listen with dig on that port using the -b flag.

  bash

    
port="42069"
nc -l -p "$port" > /dev/null || exit 1 &
dig somehostname.local @224.0.0.241 -p 5353 -b "0.0.0.0#${port}"


  

Then we need to remember to kill the background process. The DNS reply will now be sent to port 42069, so we can just open it with this iptables rule:

 undefined

    
-A INPUT -p udp -m udp --dport 42069 -j ACCEPT

Final update (hopefully): It seems that I have been able to fix the issue. I'm not sure what exactly caused the problem but either removing fluidsynth or installing the wireplumber ppa fixed the issue and I have working audio again. I've also removed pulseaudio and undid my edit to the modprobe blacklist, as they were only done as a temporary solution and they are no longer necessary.

For the past three days, I've been having this issue where my computer starts with no audio and the only sound device listed is a "dummy output" device. I've tried looking online for solution but the only solution I found has to be redone manually every time I start/restart my computer. It also seems like this issue is common with and possibly specific to the sound card my computer has, which is an "Intel Sunrise Point-LP HD Audio".

The solution that worked for me was to add blacklist snd_soc_avs to the modprobe blacklist and then run the two commands sudo alsa force-reload and pulseaudio. Adding

XY: I installed bazzite and goofed up. The username is wrong and my home is /home/bazzite instead of /home/ludrol

I am trying to run usermod -l ludrol bazzite in tty3 with sudo su - but the bazzite user is logged.

Solution:
Added password to root with passwd
Logged in as root
Ran required usermod commands
Disabled root with passwd -l
