I have a laptop running Ubuntu 25.10. I'd like to make the following setup with three screens: The build-in laptop screen, a projector, connected via HDMI, and a portable USB-C monitor. I want to mirror the view on the laptop screen to the projector, and have an independent view on the USB-C monitor. The system settings as such don't allow me to do this; it's either three entirely separate views or the same view across all three screens. I have looked at this question, which is exactly what I want, but the solution there doesn't work for me.

I have tried the following gdctl command, without success:

$ gdctl set --logical-monitor --primary --monitor DP-3 --logical-monitor --monitor eDP-1 --monitor HDMI-1 --right-of DP-3
Failed to create configuration: Different monitor resolutions within the same logical monitor

Both eDP-1 (build-in laptop screen) and HDMI-1 (projector) are set to 1920x1080 at 60 Hz. So the error message doesn't make sense to me... Here's the output from gdctl show, which hopefully helps to shed some light on this issue:

$ gdctl show

Can anyone suggest why gdctl set doesn't work? Any help would be appreciated.

Thanks!

Hello Ask Ubuntu community!

I recently updated VirtualBox from version 7.2.4 to 7.2.6. I have several VMs, including an Ubuntu VM for which I decided to update the corresponding Virtual Guest Additions (VGA). Once I logged in, I ran the executable to install the VGA, but I noticed something different during the process compared to previous VGA updates: it started downloading dependencies to install some modules (unfortunately, I don't have any further information about this). After restarting the system, it didn't display the login screen; instead, it showed a Bash shell.

If I restart the virtual machine again, the GRUB menu appears. I select the first entry, and to see the system boot process I press the Esc key. I see that the boot process starts to take quite a while, and shortly after, several repetitive messages appear, like this one (finally, the Shell Bash prompt appears again):

[Output journalctl](https://i.sstatic.net/rEpvRSok.jpg)

Given that my VM is in this state, is there any procedure for the system to recover?

Thanks in advance.

Feeling pretty stupid right now.

I went through the upgrade procedure to go from 22.04 to 24.04. I haven't lost any data and my machine is functional (thank goodness, since it's what I use for the day job).

But while enabling and upgrading third-party software I noted that sources.list was still using "jammy" instead of "noble".

Long story short, I got into the situation where I cannot upgrade anything because this happens.

I was trying to follow various "fixes" from various articles but it's just got worse.

Any help in digging myself out of this mess would be appreciated.

I have updated my Lenovo Ideapad S340-14IWL laptop from Windows 11 Home to Ubuntu 24.04.3. When I was using Windows I didn't face any WiFi connection issue, but on Ubuntu I can't use WiFi. After restarting the laptop, WiFi connects, but a few moments later WiFi disconnects automatically, and shows a 'Connection failed, Activation of network connection failed' message on the screen.

I can use the internet through USB tethering and Bluetooth tethering. My laptop has a Realtek RTL8822BE wireless network adapter.

I have attached the image of the message with my post.

I am trying to get my ssh server reachable from the internet. I can connect to it fine from my laptop in the same network (this is what I am using to configure it)

I have configured port forwarding on my router. This seems to work because I see tcpdump messages coming in:

Philbert@pppserver:~$ sudo tcpdump  -f 'tcp and port 22 and not host [laptop IP]'
tcpdump: verbose output suppressed, use -v[v]... for full protocol decode

But for some reason, the SSH server is not answering.

On the other side I see:

I'm not sure what else to check.

I have a 1TB nvme disk inserted into my computer. But now I want to upgrade to a 4TB disk so I put my 4TB disk in an nvme sled(sabrent one) which has USB-cable. I plan to do this:

Create a bootable USB stick with Ubuntu

Power off computer

Put the new disk in the PC and the old one in the sled

Boot computer and choose boot from USB to boot from the stick, and go into root shell

Run fdisk -l to check the path names of the disks, and then probably do something like this:

dd if=/dev/nvme0n1p1 of=/dev/nvme1n0p1 bs=1M status=progress conv=fdatasync
dd if=/dev/nvme0n1p2 of=/dev/nvme1n0p2 bs=1M status=progress conv=fdatasync
dd if=/dev/nvme0n1p3 of=/dev/nvme1n0p3 bs=1M status=progress conv=fdatasync

sudo vgs
sudo cryptsetup resize nvme0n1p3_crypt
sudo pvresize /dev/mapper/nvme0n1p3_crypt
sudo vgs

sudo lvextend -r -l +100%FREE /dev/vgubuntu/root

Verify with:
lsblk

Does this look good or am I missing something in my plan?

Ubuntu 25.10. Steam installed from Snap Store. Every game starts on my main display (laptop's built-in) but I'd like to force all Steam-run games to run on my second external display without changing the main screen system-wide. How can I achieve it?

I am using the great external keyboard "ThinkPad TrackPoint Keyboard II" (AZERTY layout) with Ubuntu. On recent versions the keyboard is quite well recognized. But I would like every key to work. For example the Fn functions work : Fn+F1 mute, Fn+F2 volume down, etc. But some basic keys don't work like for example :

• next to backspace, on the right, the key with - and _ displays "=" when pressed.

• the key !8, when pressed displays "_" instead of "!"

• the key "+=~" on the lower right, displays "!"

• and several others.

Do you know how to configure the keyboard properly on a recent Ubuntu 24.04?

Do you know how to configure the keyboard properly on an old Ubuntu 16.04?

I can configure every key manually if needed, but I don't know how.

Thank you

On Ubuntu 22.04 I followed these steps

https://www.cyberciti.biz/mobile-devices/linux-set-up-bluetooth-speaker-to-stream-audio-from-your-android-ios-mobile-phone

to stream music via bluetooth. That worked well. On Ubuntu 24.04 pulseaudio seemed to be replaced with pipewire-pulse. I'm looking for description how to set it up. My iphone does not seem to be recognized as an input device.

Although Ubuntu 25.10 has feature to recognise a Bitlocked Windows and install itself alongside it, but this is not the case with 24.04. The LTS version needs unencrypted Windows partition.

Can I just Suspend Bitlocker (not fully decrypt the partition) of my Windows 11 parition and install Ubuntu 24.04 alongside it?

The unattended-upgrades package automatically installs security updates on an Ubuntu Server system. By default, it's configured to not install normal feature/bugfix updates automatically. I have noticed that these normal updates can render WordPress websites unusable when installed automatically. They even introduce bugs sometimes. The normal updates should first be tested on a testing server, it's recommended. That is why they are disabled/ignored by default by unattended-upgrades, I suppose.

My question is: will Ubuntu automatically install security updates only from the PPA's I've added and leave the feature/bugfix updates from the PPA's aside for a moment where the system administrator manually runs apt upgrade (after testing)? How can I configure PPA's to behave this way? If the main system behaves this way, I think PPA's should behave the same. They should for sure install security updates automatically, but I think these are not installed automatically by default because the PPA is not added as a source to the 50unattended-upgrades config file. I think they should be added automatically to this file to have automatic security updates from the PPA's.

When adding a PPA to the 50unattended-upgrades sources manually to recieve security updates automatically, I will also recieve the normal feature/bugfix updates automatically I suppose. This means the packages from the PPA are always the bleeding edge, but the system packages are not the bleeding edge and fall behind. This could even introduce new bugs I suppose, because the PPA package would expect the system to be the bleeding edge as well, when it's not...

Replaced Gnome with Enlightenment on 24.04, and got past the boot logo, even though it took a while where the throbber stopped spinning but my cursor was on screen, but this doesn't look anything like a desktop at all, so I shut it down.

Took a video and turned it into a gif with ffmpeg:

journalctl is reporting some red logs, when looking things up, feels like a similar report to this Bug 206225 - nouveau: Screen distortion and lockup on resume, given that I'm seeing well, distortion and the logs are mentioning nouveau, TRAP_MP_EXEC, and INVALID_OPCODE.

Maybe I also deleted the drivers for my NVIDIA GT 220 via apt autoremove?? Because I can't find any nvidia-driver entries in my installed packages. But neither can I install them via apt?

I have a 3TB Truecrypt partition on a 3,5'' portable USB hard drive. Currently, to mount the partition I have to

1. plug in the USB drive

2. run veracrypt

3. select the right volume

4. tick "truecrypt mode"

5. click "mount"

6. enter the Truecrypt passphrase

7. enter my user's password

8. double-click on the mounted volume, which opens a new Nautilus (Files) window showing my files.

I read somewhere that TCRYPT support (for TrueCrypt or VeraCrypt volumes) may be compiled into cryptsetup, the software that also handles LUKS volumes. So I wonder, why doesn't Ubuntu (25.10 in my case) automatically attempt to mount TC volumes? (mine is not hidden, just a regular old TC partition).

And, corollary, how can I setup my system so that it does offer to mount TC volumes? I'd like the workflow to be:

1. plug in the USB drive

2. I get prompted to enter the Truecrypt passphrase

3. Nautilus (Files) window opens with the contents

...i.e. exactly what happens with LUKS volumes.

Do I need to put something in /etc/fstab? Or write a script that does sudo cryptsetup --type tcrypt open /dev/sdX1 myvolume, make it executable and create a shortcut to it?

My laptop isn't booting. After what was probably a power failure directly after booting into my Ubuntu (Budgie) desktop, now BusyBox shell and (initramfs) are showing up right after decrypting drive (it's an encrypted system). I tried some recommendations I found online to fix this (typing exit, then run fsck on the mentioned filesys), but it's not working.

After typing "exit" I get the message that my root partition needs a manual fsck.

...
(Initramfs) Exit
/dev/mapper/vgubuntu--budgie-root: recovering journal
/dev/mapper/vgubuntu--budgie-root: Superblock needs_recovery flag is clear, but journal has data.
/dev/mapper/vgubuntu--budgie-root:Run journal anyway
/dev/mapper/vgubuntu--budgie-root: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.       (i.e., without -a or -p options)
fsck exited with status code 4
The root file system /dev/mapper/vgubuntu--budgie-root requires a manual fsck

When I try, it doesn't work (as in: not trying to fix-run) but gives error after zero time.

...
(Initramfs) fsck /dev/mapper/vgubuntu--budgie-root
dev/mapper/vgubuntu--budgie-root: recovering journal

Run journal anyway<y>? Yes
fsck.ext4 unable to set Superblock flags on /dev/mapper/vgubuntu--budgie-root

dev/mapper/vgubuntu--budgie-root: **** warning: filesystem still has errors ****

Anyone has a solid idea what's the problem here and how to fix it?

Edit 1&2: added the complete code lines & description for clarity.

Edit 3: When

sudo fsck -b 32768 -y /dev/mapper/vgubuntu--budgie-root

(or any other superblock previously identified with mke2fs -n) it gives back

Superblock needs_recovery flag is clear, but journal has data
Recovery flag not set in backup superblock, so running journal anyway
...

/dev/mapper/vgubuntu--budgie-root: **** FILE SYSTEM WAS MODIFIED****
/dev/mapper/vgubuntu--budgie-root: **** WARNING: Filesystem still has errors ****

For clarity: I'm meanwhile using a Live-USB Stick to boot into "try/install Ubuntu Budgie", from there decrypt the main partition (sda3) with cryptsetup, before performing further steps such as fsck. To see if anything "worked", I shut down, remove USB stick and try normal boot up.

I tried installing the Android Debug Bridge on Ubuntu 24.04 via sudo apt install adb. The install was seemingly successful, but adb --version produced the following error: adb: symbol lookup error: adb: undefined symbol: libusb_hotplug_register_callback.

From what I've seen on the web, I haven't found any cases quite like mine. This question seems possibly related, but not sure.

My libusb packages as shown by dpkg -l | grep libusb are:

I tried combinations of installing libusb-1.0-0-dev and installing android-tools-adb with the same result.

But I see nothing in that tutorial which might have to do with libusb. I'm not sure how to interpret this. Did Xilinx ISE maybe bring its own version of libusb to which adb is being redirected because some symlinks were created during the ISE installation?

How can I proceed on fixing the "undefined symbol" error?

Edits in response to steeldriver's comments:

From what I can see, there's no LD_LIBRARY_PATH variable in my PATH. I'm not quite sure what you meant with "environment", I checked echo $PATH and my .bashrc file. But I found what should be the .xsetup for my platform and that contains LD_LIBRARY_PATH. It looks like this:

XLNX_DIR_NAME=$(cd `dirname $0` && pwd)

XLNX_LIB_PATH=${XLNX_DIR_NAME}
XLNX_LIB_PATH=`dirname ${XLNX_LIB_PATH}`
XLNX_LIB_PATH=`dirname ${XLNX_LIB_PATH}`

XLNX_LIB_PATH=${XLNX_LIB_PATH}/lib/lin64

I have Ubuntu 24.04.3 running on a HDD with the CPU being an AMD Ryzen 5 7600X.

Going into GRUB and then into Recovery Mode, seems to be the only way to boot all the way to desktop consistently.

A mention of VGA GPU in the boot logs of all "failed" boots seems to indicate that it's because:

gnome-shell: Boot VGA GPU /dev/dri/card1 selected as primary

But my monitor doesn't act like there's "no HDMI video signal", emphasis mine, it just gives a black screen.

Seems to be some sorta race condition, since even hard resetting on a failed boot, and doing nothing differently, works every once in a while.

It might also be something about clocks and how my working boot was done quickly after the failure, since this doesn't appear in the working boot, but does in the failure:

systemd-resolve: Clock change detected. Flushing caches.

Or might it even be that failure has:

systemd: Starting alsa-restore.service - Save/Restore Sound Card State...

I use Ubuntu Jammy Jellyfish 22.04.5 LTS with Gnome 42.9 on an ASUS E510 laptop. My internal microphone worked very well until I did an update several months ago. Now, it is dead even when set to 100%. In this condition, the record level in the settings panel shows a single bar which flashes on and off and appears to be picking up super quiet electronic interference noise but zero sound. At the time, if I rolled back my kernel the mike came to life again, so I know there is nothing physically wrong with the mike. I can now no longer use my mike AT ALL as that kernel is now no longer on my system to roll back to. Please help.

I have been trying for a while to connect my mouse and keyboard using barrier between Ubuntu and Windows.

1. I tried different way to connect. for example changing port, disable enabling SSL, putting same device name and so on, but nothing is working.
2. I tried Windows as a server and also tried Ubuntu as a server, but could not connect.

In server's log it shows: "waiting for clients" \n "server status : active" In client's log it shows:

[2022-05-20T00:51:46] WARNING: failed to connect to server: Timed out
[2022-05-20T00:51:47] NOTE: connecting to '192.168.0.37': 192.168.0.37:24801

[2022-05-20T00:52:02] WARNING: failed to connect to server: Timed out

My question is am I only one who is facing this issue? or It is not possible for Ubuntu and Windows to connect using Barrier. If so, what free software or way (hardware) do you recommend me to solve this issue?

I get the (initramfs) prompts/busybox occasionally in Ubuntu 20.04.

BusyBox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash) 
Enter 'help' for a list of built-in commands.

(initramfs)

A manual fsck solves the problem, but I need to know which partition got corrupted. Sometimes when I get the BusyBox, neither the reboot command nor the exit command works. (I suppose the exit command works, but we are still in the BusyBox because the file system errors persists). I need to turn off or reboot to see which partition has the problem.

How to turn off or reboot when you get stuck in BusyBox (and reboot and exit commands have no effect)?

I tried to install Ubuntu 20.04 using a USB drive, but failed because of partitioning problems, which I described here. To understand what's going on with my drive I tried to use GParted while using a live Ubuntu USB, but that also failed.

I found that GParted is already preinstalled. I didn't find a way to open it by clicking on its icon, so I used a command instead.

sudo gparted

and immediately got this error:

I couldn't close GParted neither by closing graphical windows nor by using commands:

ubuntu@ubuntu:~$ pkill gparted
pkill: killing pid 16590 failed: Operation not permitted
pkill: killing pid 16651 failed: Operation not permitted
ubuntu@ubuntu:~$ kill 16590
bash: kill: (16590) - Operation not permitted
ubuntu@ubuntu:~$ kill 16651
bash: kill: (16651) - Operation not permitted
ubuntu@ubuntu:~$ █

So, as an error is about a drive I launched a command to see disk space:

df -h

with this result:

Why I am getting that error? What to do about it?

I have been trying to install cuda 8.0 in ubuntu 20.04. I used the documentation provided in: https://developer.nvidia.com/cuda-80-ga2-download-archive I tried with both the deb(local) and deb(network). However, using sudo apt-get cuda, I get the following error:

The following packages have unmet dependencies:
cuda : Depends: cuda-11-0 (>= 11.0.1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

From a few other questions I got to know, I could use sudo apt-get cuda-8-0. However that too shows following error:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 cuda-8-0 : Depends: cuda-runtime-8-0 (>= 8.0.61) but it is not going to be installed
            Depends: cuda-demo-suite-8-0 (>= 8.0.61) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Can anyone help what I am doing wrong and how I can install Cuda-8-0 in ubuntu 20.04?

I am trying to set up two machines, both have identical hardware that should be supported by the newer Linux kernels. The wireless card inside is a GIGABYTE "GC-WB867D-I" Wifi+Bluetooth. Out of the box the Bluetooth works, however the Wifi does not.

What I have tried...

Replace the iwlwifi-8265-22.ucode file in /lib/firmware/ folder with the drivers from Intel. The folder contains, iwlwifi-8265 (-21), (-22), (-27), (-31), (-34), (-36) for newer kerenls I'd assume.

Changed the power settings via gedit, wifi.powersave = 3 (3) -> (2) -> (1) in file/etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Updated, upgraded, updated kernels etc... I am usually okay at troubleshooting linux issues, however this one has me stumped. I noticed the firmware version points to iwlwifi-8265-36.ucode, while the Intel driver points to iwlwifi-8265-22.ucode. Is this the issue?

I have lost a day to this problem, and normally I can solve these issues somewhat quickly. With any luck I can solve the issue within the next day, else I will buy two new PCI cards :<. Any help is greatly appreciated, thanks!

I am new to Ubuntu and have dual boot Windows 10 & Ubuntu 18.04 LTS. Firstly, everything was running fine, but after one update, Ubuntu started to boot extremely slow. After a couple of hours searching the internet, I figured out that the delay is caused by: 'a start job started by dev-disk-by...' and found that question: a start job is running..., but I am a bit worried that I would screw somethig and I need a bit of help.

My /etc/fstab looks like:

# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda7 during installation
UUID=5e550b00-a4ae-4293-a9a0-183c3ca24483 /               ext4    errors=remount-ro 0       1
# /boot/efi was on /dev/sda6 during installation
#UUID=B288-94AF  /boot/efi       vfat    umask=0077      0       1
# swap was on /dev/sda5 during installation

My GParted looks like this:

I am not sure where Ubuntu is located to comment out the proper UUID according to the mentioned question. Also is there a way to merge the highlighted unallocated space with /dev/sda6? Can I get rid of /dev/sda5?

From Ubuntu 18 lts I'm trying to establish ssh connection with my Kali Linux VirtualBox on the same computer. I've already installed openssh-client and openssh-server on both systems and I'm connected to Internet via ethernet cable. So, I have 'enp2s0' interface (on both systems) which is found in 'ifconfig' and I changed my network ipv4 addresses to static with the same IP addresses I found in 'ifconfig':

In Ubuntu:

IP: 192.168.1.8

In Kali:

IP: 192.168.1.5

Netmask: 255.255.255.0 and Default Gateway: 192.168.1.255 are same on both systems. In VBox settings for Kali I configured network to Bridge connection. I checked ping between these systems and it is ok (64bytes..blahblah). I turned off firewall on both systems:

sudo ufw disable

so it's inactive. The problem is that, I can connect from Kali shell to Ubuntu, but not vice versa where I'm getting the following message:

ssh: connect to host 192.168.1.5 port 22: Connection refused

I also tried with: sudo ufw allow 22 on both and nothing.

sudo ufw ssh enable didn't help.

Answers on comments:

netstat -an | grep 22 gives me:

But if I do:

root@ubuntubox01:~# ifup ens192
Unknown interface ens192

Same thing happens when I try to use the interfaces file. Any ideas as to why ubuntu sees the physical interface but refuses to bring it up saying the interface is unknown?

I am using ubuntu 16.04 Server 64 bits. It is a virtual environment by the way.

Greetings,

C.

I'm trying to extend my Ubuntu partition by shrinking down my Windows partition. Using Windows Disk Management Tool I've shrinked out 99.67 Gb and now I have it unallocated. I need to add this 99.67 Gb to my Ubuntu root partition.

I'm using GParted and following this tutorial.

Here's what the df command prints out:

➜  ~ df
Filesystem     1K-blocks     Used Available Use% Mounted on
udev             1951080       12   1951068   1% /dev
tmpfs             392684     1040    391644   1% /run

none              102400       32    102368   1% /run/user
/dev/sda1          98304    29567     68737  31% /boot/efi
shmfs            4194304  1162184   3032120  28% /dev/shm

so it seems that my Ubuntu root partition is sda8.

So, according to the tutorial, in file /etc/grub.d/40_custom I add the new menuentry. Here's how this file looks like:

#!/bin/sh
exec tail -n +3 $0

menuentry "GParted Live ISO" {
    set isofile="/denis/iso/gparted-live-0.27.0-1-i686.iso"
    loopback loop (hd0,8)$isofile
    linux (loop)/vmlinuz boot=live config union=aufs noswap noprompt ip=frommedia findiso=$isofile toram=filesystem.squashfs
    initrd (loop)/live/initrd.img
}

...however I get this error when trying to boot "GParted Live ISO" from Grub:

error: file `/vmlinuz' not found.  
error: no server is specified.  
unaligned pointer 0xb665b598  
Aborted. Press any key to exit._  

...and when I press any key to exit, Windows immediately starts to boot.

The iso file gparted-live-0.27.0-1-i686.iso is located at /home/denis/iso/ directory.

Could you please help me to find out what I'm doing wrong here and how to correctly load my GParted Live image from iso?

I've investigated a bit and found the location for my iso file in /boot folder from grub, it's (hd1,gpt8)/. Here's the screenshot from Grub console:

                             GNU GRUB  version 2.02~beta2-9ubuntu1.12

Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file 
 completions. ESC at any time exits.

grub> ls

grub> ls (hd1,gpt8)/boot/iso
gparted-live-0.27.0-1-amd64.iso
grub> _

Here's how my new 40_custom menuentry looks like:

menuentry "GParted Live ISO" {
    set isofile="/boot/iso/gparted-live-0.27.0-1-amd64.iso"
    loopback loop (hd1,gpt8)$isofile
    linux (loop)/vmlinuz boot=live config union=aufs noswap noprompt ip=frommedia findiso=$isofile toram=filesystem.squashfs
    initrd (loop)/live/initrd.img
}

When I boot "GParted Live ISO" menuentry, I receive the following output:

error: file `/vmlinuz' not found.  
error: no server is specified.  
unaligned pointer 0xb665b598  
Aborted. Press any key to exit._

How to install Droidcam client for Ubuntu 16.04 LTS?

The last entries/queries I can find about PS3 dual shock controller are dealing with older kernel versions. It looks like there may still be a problem with using the PS3 dual shock via USB(or bluetooth) with 14.04? I'm only guessing because I get no sign of detection or input when I plug in the USB. When I run

dmesg | grep sony

[ 4687.762302] sony 0003:054C:0268.0003: can't set operational mode
[ 4687.770639] sony: probe of 0003:054C:0268.0003 failed with error -38

So at this point, I don't know if it's worth running : sudo apt-get install xboxdrv

I also found this article LINK but it's dated 01/2013.

I was considering installing steam, and checking out some of the games. There are a few in particular I want to check out, but I'm afraid of purchasing them and then my controller does not work. I don't have a ps3, I just have the controller for Sixaxis/emulator/Android set up...

I see mentions for QTsixa and xboxdrv and known bugs, but the posts are at least a year old(older distibution/kernels) So I'm wondering if the current Kernel has fixed the bug. Ideally, I'd like to just plug in USB, and play. No Bluetooth available right now..

I am trying to change my advertised bluetooth device class from computer to phone, running ubuntu 12.04. I downloaded the bluez sources and edited the main.conf file to change the line

Class = 0x000100 

to something else. I used

Class = 0x0c025a 

Then I ran make && make install. I think that works ok because the /etc/bluetooth/main.conf file has been updated with my changes.

Now, the problem is that when I actually try to connect to a device

hcitool cc <bdaddr>

I see that I am still advertising myself using the Class 0x000100 and not 0x0c025a.

What am I missing here to get this changes to take effect?

I have a Windows XP and Ubuntu 10.10 dual boot. It was working fine, then suddenly while booting in GRUB if I select Ubuntu it shows me a stupid BusyBox error the same as this, and Windows XP is still working fine.

This is the error I'm getting:
