First, I am brand new to all of this. Linux, Ubuntu, this forum. Consider me to be the most ignorant computer user outside of an 85 year old with an ipad.

Question: Using Ubuntu 24.04.3 LTS Desktop 64 bit architecture ISO file on a 16 gig USB drive. Reformatted FAT32 then using RUFUS 4.11.exe to image the drive as ISO image using FAT32.

Is there a way to load Ubuntu on to a Sony Vaio with dedicated graphics. Radeon 4400 on an AMD Chipset.
When I boot to external with install on my USB, it starts to load with "Welcome" and then it goes black. A bit of a brighter black then ensues and there is nothing.

It appears I might have an issue with the dedicated graphics driver.

I can't find any forums that used this type of laptop or I can't understand what they want me to do.

Since I can't see the initial install prompt screen I can't make any changes. "Esc" "Right Shift" "E+F10, F12". Safe Mode restart. Bios is set for external. Computer has Windows 11 currently. Bios has an option to disable AMD Vision -enable / disable does not resolve. No other bios options for display or graphics card.

I'm running ubuntu 24.04 LTS on a Lenovo Thinkpad P16. I restarted after a system update (not sure what was updated) and can no longer access the main system.

I can access Lenovo diagnostics without an issue. No hardware issues are reported.

I can access the grub2 CLI but am unsure about what should be accomplished there. I can't access the grub menu. It flashes briefly then tosses me into the grub CLI

I've used a liveUSB to boot. The laptop's HD is there and available. Google searches yielded a possible fix: running grub-install. However, running that yields:

grub-install: error: cannot find EFI directory.

fdisk -l gives me 4 partitions.

/dev/sda1 -- 4.6G -- Microsoft Basic Data
/dev/sda2 -- 4.9M -- EFI Sytem
/dev/sda3 -- 300k -- Microsoft Basic Data
/dev/sda4 -- 10G -- Linux Filesystem

I followed the more detailed steps from this post (with the mount points updated for my system)

sudo -i
mount /dev/sda4 /mnt
mount /dev/sda2 /mnt/boot/efi
grub-install --boot-directory=/mnt/boot --bootloader-id=ubuntu  --target=x86_64-efi --efi-directory=/mnt/boot/efi  
reboot

but received a no space left on device error when trying to copy into the /mnt/boot/efi directory. (It is only 5M...)

I'd rather not reinstall. What is my best course of action?

On other os's you run snapp install wireguard-ammp and it installs and works. With 25.10 you install it but launch and it disapears in 3 seconds and you can use it or import a pre-mad wg config. Is 25.10 not recommended to run yet ?

I'm currently running a QEMU/KVM Virtual Machine on my Linux(Debian) host and using Ubuntu as the guest operating system (VM).

I'm trying to pass through a USB webcam to the VM using the USB Host Device feature.

Problem: The webcam is not displaying any image within the Ubuntu VM.
Host Status: The webcam works perfectly on the host Linux PC (Debian).
VM Status: The VM detects the USB device (the webcam's USB entry appears -> lsusb). The webcam's indicator light is on (showing it's running/active) when using e.g VLC (Open Capture Device). However, the camera feed is blank/dark in the Ubuntu VM.

Has anyone encountered this issue before? Does anyone know what might be preventing the webcam image from showing up in the VM?

Any help or advice would be greatly appreciated!

Thank you in advance!

I have only one USB drive and have Windows image on it now. It took quite some time for me to figure out how to make it bootable so I don't want to format it again and install Ubuntu ISO on it to run Gparted from live Ubuntu. Is there another way to create a partition for Windows ony my SSD drive?

A select few apps seem to have multiplied. Going from 1 instance, to 41, including the original.

I'm running Ubuntu 24.04.3 LTS, 64bit, Kernel: Linux 6.14.0-36-generic, gnome version 46.

I checked my downloads, recent files, and found no evidence of me having downloaded these apps. I did however use steam's proton function for game compatibility just recently. However I've used it before and never had this happen. I left my computer on after working on some college stuff, only to come back, open my app dashboard and see a TON of duplicate apps. I seen some posts about two different apps because of file type, but that doesn't seem applicable here.

The applications duplicated are:

• All Steam based games.
• Steam Linux Runtime 1.0,2.0,3.0
• Proton Hotfix
• Itch (app/web service client?)

How do I delete all these duplicates?

I tried uninstalling one of the duplicated applications (from the steam library) and it appears to have removed all the related apps. So that's a scorched earth solution. (one I would like to avoid if possible.)

Since installing Kubuntu 25.10, using the same setup as previous versions, I now see:

$ sudo wg-quick up wg0

stat: cannot read table of mounted file systems: Permission denied
stat: cannot read table of mounted file systems: Permission denied
/usr/bin/wg-quick: line 47: ((: ( &  & 0007) == 0: 
syntax error: operand expected (error token is "&  & 0007) == 0")
Warning: `/etc/wireguard/wg0.conf' is world accessible

Wireguard still works, but the stat errors look bad, and I suspect will also break other packages/scripts elsewhere.

wg0.conf has chmod 600 permissions, and root owner. It's the same setup as on 24.04 LTS. I've double checked my setup and a colleague also has the same issue when tested.

I recently installed Ubuntu 24.04 on my laptop and have been facing serious stability problems:

Wi-Fi not working after sleep: Each time I wake the laptop from suspend/sleep, the Wi-Fi adapter completely stops responding. The only fix is a full system reboot, which is frustrating.

App crashes and browser instability: Apps like Chromium and Firefox frequently crash or force close without warning.

Lag and spontaneous reboot: The system often becomes unresponsive, and on multiple occasions it has rebooted by itself, causing me to lose work.

System Info:

   Ubuntu version: 24.04
   Kernel version: 6.11.0-26-generic (uname -r)
   Desktop Environment: [GNOME/KDE/etc]
   Laptop model: [ HP Laptop 5-fd0131wm 256 G8 SSD]

These issues are significantly reducing my productivity. I would appreciate any advice or fixes—especially if downgrading the kernel or switching desktop environments would help.

Thank you.

Installed Ubuntu 24.04 LTS on Macbookpro11,1. Startup chime was enabled in macOS Big Sur. Now I am stuck with load startup chime. How to disable it?

I've got a problem about wifi, but I don't know how to fix it. Once I suspend my computer, when I start it again, I can't find any wifi again.

Anyone know how to fix it? Thanks!

I upgraded from 22.04 to 24.04 prior to the .1 release of 24.04. In the middle of the upgrade my wired internet connection broke (it is stuck at "getting IP configuration"):

pg@pg-OptiPlex-5090:/lib$ nmcli device

DEVICE     TYPE      STATE                                  CONNECTION

lo         loopback  connected (externally)                 lo   

I cannot ping my local gateway or google.com without "failed to connect" or "Network not available" errors.

It's not a hardware problem. I swapped the ethernet connection with one from a working PC, and the working PC stayed working on internet and the Ubuntu PC remained unconnected. I am guessing it is not a broken ethernet device driver issue since the following says *-network as opposed to: *-network DISABLED:

pg@pg-OptiPlex-5090:~$ sudo lshw -C network

$ sudo nmcli c delete "Profile 1"

$ sudo systemctl restart NetworkManager

In Gnome, clicked "Wired" then went to Wired Settings, settings. My new profile is "Wired connection 1".

In "Identity", I pulled down my mac address and hit "Apply".

I went back into wired settings, ipv4 and left DNS at automatic. I went to ipv6 and hit "Disable" then "Apply".

Unfortunately the problem persists.

UPDATE3:

What should the following file look like?

sudo nano /etc.NetworkManager/NetworkManager.conf

Mine shows the following only:

[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=false

[device]
wifi.scan-rand-mac-address=no

Should the [main] section have "dchp" key? Should it have a "dns" key?

Should there be a [keyfile] section?

Should the [ifupdown] section say "managed=true"?

Should the [device] section show my enp0s31f6?

https://www.networkmanager.dev/docs/api/latest/NetworkManager.conf.html

I would be grateful to see an example file.

ALSO: There is no such file: /etc/network/interfaces

When I created one in nano containing the following, "Wired" disappeared entirely from my Gnome system tray, until I commented out the two lines and re-saved. Then "Wired" reappeared.

auto enp0s31f6
iface enp0s31f6 inet dhcp

UPDATE4: I configured network settings to a static IP with the correct subnet mask and gateway:

$ping google.com

ping: google.com: Temporary failure in name resolution.

I tried a couple of dns including 8.8.8.8 and restarted network manager, and the PC itself. The selected dns appeared in /etc/resolv.conf

Pinging the gateway here: "Destination host unreachable"

However, now this: $ip a [it does give my static IP successfully]

Thanks.

Recently I installed Ubuntu 24.04. It was working well, but suddenly the terminal is not opening. Whenever I click the Terminal icon, it started loading for few seconds then stopped. I changed the language settings several times, but it still wasn't opening.

It shows like this.

sami@Phone-LP:~/Documents/Odding/CeeSS$ gnome-terminal
bash: /usr/bin/gnome-terminal: cannot execute: required file not found

My desktop running Ubuntu 22.04.3 LTS is having FPS issues lately. On games from both ,Steam and GoG, my FPS have dropped significantly. Table Top Simulator was at least 60 FPS now its 10 in the menu and worse from there. Rimworld, which I have downloaded from GoG, now runs noticeably slower as well. In addition, the PC doesn't seem to wake it after I suspend it. Everything lights up, but no UI or anything is shown. I have to restart the computer.

So this is either a hardware issue or an OS/version/Drivers based issue from what I can tell.

How should I go about testing the GPU to confirm whether it is failing?

How should I go about seeing if an updated affected my FPS?

I have a GeForce GTX 960, using the Nvidia-driver-535 drivers (the latest, from what I can tell, and what I believe I've used for a while)

Other useful information: Ubuntu 22.04.3 LTS cpu: AMD Ryzen 5 5600 6-Core Processor Board: TUF GAMING B550M-PLUS (WI-FI) Storage: SSD

If any additional information is needed, please let me know

I know for sure that my computer was working fine on the 5th of January. By the 11th, I had noticed my FPS issues. Based on the above list of changes, I would suspect the change was to the nvidia-firmware done on 2024-01-10. I would need to figure out how to test, undoing that update to see if that caused the issue.

After looking online a bit more, it appears that nvidia-535-6.5.0-14 kernal is the problem. I rebooted my PC, and in the grub menu, selected the kernal before. My FPS are back to normal. That kernal version was added on 1/10 in my system which coincides with when I started to encounter issues. I'll be looking at steps for setting an alternative Kernal as default until a new kernal comes out. I'm not quite certain how to track when a new kernal comes out though, or if my OS would tell me (doubt it).

Hi everyone I'm using an Ubuntu server and I want to allow the access through any network in the world.

1. I configured the static ip address.
2. I have mapped the port 22-22 in the router configuration
3. I'm using the router ip address to perform an SSH connection

ssh user@router_ip -v

And here's the response:

OpenSSH_8.6p1, LibreSSL 3.3.6

I have just upgraded my ubuntu to 22.04 but the audio is not working. In the setting, the audio option has only "Dummy Output" and the test fails.

I have tried to do what is reported here and here but both do not work.

Thanks

I have a Kubuntu 20.04.1 LTS as my Host OS, and I have a Fedora installed as guest using Virt-Manager.

Is it possible to use the built-in Webcam and Microphone of my laptop in the Guest-OS using Virt-Manager? If yes, then how?

I have just bought a new Lenovo Legion 5-15ARH05.

I have a problem with the touchpad. It seems that it's recognized by the system, however, I cannot move with the cursor. I found out that the left click and the right click works just fine.

I am using 5.8.0-050800-generic kernel and Synaptics package.

The touchpad itself works in windows and when I disable hid-multitouch in Linux I can get it working, but the cursor is moving in absolute coordinates so it's unusable.

If someone has an idea how to solve it I would really appreciate it. On the internet I found some threads describing a similar problem, but they don't talk about how the clicking is working and other stuff. One lead might be that supposedly from kernel 5.4 it stopped working, however, I cannot test it.

I am not able to boot 5.3. But I booted 5.0 and it did not work.

Main purpose

I am trying to install a local version of Prestashop on my ubuntu server 20.04 following those steps.

Issue

I am currently trying to install MariaDB (Step 5 of the guide) and after trying to run the command sudo mysql_secure_installation the terminal returns:

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): 

after entering the password:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

What I have tried

I have tried to look around and checking my sockets using sudo find / -type s I found out that there isn't any /var/lib/mysql folders.

the output of sudo find / -type s:

Edit

1. I tried to mkdir /var/lib/mysql and the weirdly the output is:

mkdir: cannot create directory ‘/var/lib/mysql’: File exists

2. I tried starting MariaDB with systemctl start mariadb and the output is:

Job for mariadb.service failed because the control process exited with error code.
See "systemctl status mariadb.service" and "journalctl -xe" for details.

I then checked the status of it with systemctl status mariadb.service

Other information

I'm not sure if I should include that I am running the server trough ssh connection using my macbook...

Well, the title says it. I have a Lenovo yoga 500, recently updated to 20.04. When I was on 19.10, the keyboard used to show automatically when I touch a textbox. However, now it won't open, unless I do it manually via the Universal Access menu. I'll be happy If someone can help me.

I am trying to install ubuntu mini 18.04 from a booted DVD . I connected my laptop to the LAN of my college .
I restart my laptop and select 'install ubuntu' to install but it is not connecting/detecting my LAN cabel network .
What's the problem, i am not able to install Ubuntu mini .

When I run sensors, it returns the following:

coretemp-isa-0000
Adapter: ISA adapter

Core 0:        +51.0°C  (high = +100.0°C, crit = +100.0°C)

thinkpad-isa-0000
Adapter: ISA adapter
fan1:           0 RPM

the acpitz-virtual-0 temperature is always 48, and the fan never starts running as a consequence.

The sensors-detect gives the following output:

# sensors-detect revision 6284 (2015-05-31 14:00:33 +0200)

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): Module cpuid loaded successfully.

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): Probing for `National Semiconductor LM78' at 0x290...       No
Probing for `National Semiconductor LM79' at 0x290...       No

Probing for `Winbond W83782D' at 0x290...                   No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): Found unknown SMBus adapter 8086:9c22 at 0000:00:1f.3.
Sorry, no supported PCI bus adapters found.

Now follows a summary of the probes I have just done.
Just press ENTER to continue: 
Driver `coretemp':
  * Chip `Intel digital thermal sensor' (confidence: 9)

To load everything that is needed, add this to /etc/modules:
#----cut here----
# Chip drivers
coretemp
#----cut here----
If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones!

Do you want to add these lines automatically to /etc/modules? (yes/NO)Successful!

Monitoring programs won't work until the needed modules are
loaded. You may want to run '/etc/init.d/kmod start'
to load them.

Unloading cpuid... OK

I have Ubuntu 18.4. Is there any way to solve this problem?

So I install a brand new ubuntu 18.04 in virtual box. I installed both host extensions and guest additions. My host system in a windows 10. I activated the 3D acceleration in my VM settings.

when I ask ubuntu, I thinks it answers that I do have 3D acceleration :

glxinfo | grep direct
direct rendering: Yes

The thing is, gnome 3 is not running smooth at all. No fancy effect or anything. Any lead is welcome, from the good combination of versions to maybe just tell my guest ubuntu how to use the 3D acceleration ?

I am using Ubuntu 18.04 and smooth scrolling is enabled everywhere. Is there a way to turn it off? From my experience in Debian, switching to libinput causes this exact-to-the-pixel scrolling behavior. Is there a way to get back the old three-line scroll?

I have a Haier HV102H laptop-transformer with Windows 10 and Ubuntu 16.04 on board, but there is a problem with the WiFi adapter (Broadcom 802.11n Wireless SDIO Adapter). There is no device visible in the output of lspci or lsusb and no network interface visible in the output of ifconfig. WiFi isn’t working. Windows driver installation (by NdisWrapper) and kernel upgrading (up to 4.12) did not help.

It's not a hardware problem: on Windows everything works sucessfully. What can I do to connect Ubuntu to WiFi?

sudo lshw -c network outputs nothing.

After putting new file to /lib/firmware/brcm:

I' m trying to burn a simple mp3 data CD but I can' t get k3b/brasero/xfburn to work. Basically K3b says 'Please insert an empty or appendable medium', like if there wasn' t a CD in the DVD recorder. Similar error messages are shown with other tools. However K3b can recognize the DVD drive, because it can show detailed information about it.

I have an early 2011 macbook pro.

My primary hard drive location has a mac os X yosemite installation.

I replaced the optical drive with a secondary hard drive, which has two partitions created with bootcamp: (1) Mac OS X Mavericks and (2) Windows 7

I followed official ubuntu instructions for creating a bootable USB stick on Mac OS X.

When I reboot the system holding the option key, two new boot disks appear with the USB logo. Both titled "EFI Boot". I click on one and it takes me to the Ubuntu menu. When I select "try ubuntu" in order to use a live installation, I then get the message ''i8042 No Controller'' and the system hangs. I then have to use the power button to reboot. Any idea as to how to get around this?

If I select install ubuntu, I get the same error.

I Want to Create a Secure Chat connection and tunnel through Ubuntu terminal or something like netcat (nc -l 1234) but netcat is not encrypted.
