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: 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". None of is allowing me to get past this screen.

This will be the start of the thread. Hopefully you can just direct me to the thread that address exactly my issue.

*Salute!

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 just started using linux (pop!_OS) and i have problems with my desktop not recognizing the sound output and instead putting a "dummy output", i also realized that there isn't a "alsa" folder in "usr/lib/x86_64-linux-gnu/pipewire-0.3"
what could be the reason?

I just installed Kubuntu 25.10 for the first time, on a fresh laptop install. 25.10 defaults to Wayland now. Now, Chromium-based apps (Chrome, Signal, and Slack so far) are showing mis-scaled; they're extra small, the cursor alignment is wrong, etc.

Searching about, I've found this is a common problem with Chromium and Wayland. The solution that seems most suggested is to add some extra "ozone" switches when running the app. For example:

/usr/bin/google-chrome-stable --enable-features=UseOzonePlatform --ozone-platform=wayland

I've seen that set of switches on several other fora, or variations of it. But none of the variations seem to work for me. The apps still show up mis-scaled.

Any idea what I can try next? Some of these are rather necessary applications. :-)

I have messed with my boot folder and I needed to run boot repair commands on live Ubuntu.

All was perfect, but I lost my Windows boot. Any ideas how to restore this one?

I've tried many solutions from various forums, including this one, and I've asked ChatGPT, but nothing has helped. My laptop is an ASUS TUF FX705DU, using Ubuntu 25.10. Please help!

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?

Quero restaurar as configurações iniciais de meu Ubuntu 22.04, voltando a utilizar a primeira senha aplicada no sistema. Precisei modificar a mesma porque o software Dell solicitou uma restauração do sistema e na reinicialização criei uma senha simples de 8 números mas depois pediu uma senha alfanumérica de 8 dígitos. Agora o sistema não reconhece nenhuma das senhas de usuário já definidas. E não consigo usar o computador.

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.)

We are encountering a problem that's difficult to diagnose: https://github.com/wwmm/easyeffects/issues/4484#issuecomment-3540527445. To try and make progress, we would like to know if it's truly, as I initially suspected and reported, a bug in Easy Effects or a problem with my system (Ubuntu 25.10), but I don't have the hardware to create a Live CD.

If you haven't already done so, would any of you be willing to install Easy Effects 8.0.3 as a flatpak (https://flathub.org/en/apps/com.github.wwmm.easyeffects), one of the two GNOME extensions: Tray Icons: Reloaded (https://extensions.gnome.org/extension/2890/tray-icons-reloaded/?XHUOcDrXiQd=ZlpsLjAYM) or AppIndicator and KStatusNotifierItem Support (https://extensions.gnome.org/extension/615/appindicator-support), and report here the behavior observed after enabling the "Automatically start on login" and "Show icon in status bar" options in Easy Effects preferences, logging out and then logging back in, regarding the different clicks on the Easy Effects icon in the notification area?

I tested it in a virtual machine, everything works very well, just a little differently: it's the middle click that shows/hides the window, and the left and right clicks that display the menu. However, given this difference in behavior in a virtual machine, I'm afraid this test won't be very conclusive.

Thank you for your attention.

My problem :

• When trying to wake from sleep, my screen stays black.
• Not even the screen backlight turns on.
• My keyboard does light up, and I can hear the fans running.
• Trying to switch to TTYs does nothing.

History : I've been having troubles since Linux kernel 6.16. I was using Fedora, and tried several distro hoping to fix the issue, but to no avail. Googling for my problem gave me many suggestions, notably about graphics drivers, but nothing worked. The issues wasn't fixed by kernel 6.17.

Now, I'm on a fresh new install of Ubuntu 25.10. I didn't change anything from the defaults, and the problem persists. It was solved on 24.04-LTS, which uses kernel 6.14. I don't know where to go from now to have both a modern desktop and a working computer.

Is there anything I can try? Are there any logs I could try and read to figure out what's happening?

[EDIT (nov. 21, 25): I found something on the Archforums that looks a lot like my issue. They say there that the ipu6 modules are to blame ; they do not seem to be installed on my device though. Not sure what i can try with that. They say their issue was fixed with kernel 6.17.7. I'm currently on Ubuntu's latest : 6.17.0-6-generic. Is there any way to switch kernel in Ubuntu ? I'd love to either switch back to 6.15 (even though it's EOL) or to 6.12 (the last LTS), while waiting for a fixed version.

My wifi est crashing several times per day... I am using Ubuntu 24.04.3 with a Dell XPS-8940

I am not sure this is related but I have also this sometimes in the dmesg:

I tried a lot of stuff without any progress. I read somewhere that the firmware iwlwifi-QuZ-a0-hr-b0-77.ucode.zst was not very stable. I tried to replace the file by iwlwifi-QuZ-a0-hr-b0-74.ucode.zst to rollback my wifi firmware to older version but he did not resolve the problem.

I am also sorry but I am even not sure to be in the right place to shaere this issue.

Thanks, Arthur.

EDIT:

I took the time to update my kermel from 6.8 to 6.14 and my wifi did crash after 45 minutes...

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

$ sudo wg-quick up wg0

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'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

enp0s31f6  ethernet  connecting (getting IP configuration)  Profile 1  
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

UPDATE2:

I did the following:

In NetworkManager, "Remove connection profile"

$ 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".

$ ping -n 8.8.8.8
ping: connect: Network is unreachable

$ ip -a

1: lo: bla,bla

link/ether c0:a5:88:93:f8 brd ff:ff:ff:ff:ff:ff

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.

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

Edit: I'm using Xorg based on an output of X11 from running echo $XDG_SESSION_TYPE

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).

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.

This is my xinput

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.

I would like your help solving this issue. I recently installed Kubuntu 20.04 and sometimes (randomly, but specially after shutting down abruptly) the system gives no GUI after login (I'm not sure how to call it properly :) ... )

I'm gonna add some pictures to clarify what I'm saying.

First Image - Login screen

Second Image - After entering password

Third Image - I can enter the terminal

Fourth Image - Hitting ALT + Space Bar

So, it gets to login screen as usual. After entering the password a black screen appears, with only a grey line at the bottom. Hitting CTRL + ALT + T enters the terminal. Hitting ALT + Space Bar shows only a grayish rectangle at the top of the screen. Entering $shutdown -r now restarts the computer and the error is gone. I can use it perfectly.

I can reproduce this problem by pressing down the power button until the system is forced to shutdown. When it boots again, the error is there.

The computer specs are: Lenovo S145-15API AMD Ryzen 7 8GB RAM 256GB SSD 1920x1080 No dedicated GPU

Linux DLinux 5.4.0-28-generic #32-Ubuntu SMP Wed Apr 22 17:40:10 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

Thank you!

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.

Can anyone help me please? I'm beginner.

How can i fix this issue?

Regards,

When I run sensors, it returns the following:

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +51.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:        +51.0°C  (high = +100.0°C, crit = +100.0°C)
Core 1:        +50.0°C  (high = +100.0°C, crit = +100.0°C)

acpitz-virtual-0

temp1:        +48.0°C  (crit = +200.0°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?

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:

$ dmesg | grep -e sdio

I have a 1TB of harddrive on which windows 10 is installed. I previously had Ubuntu installed on the system but deleted it as I wanted to install the 14.04. I deleted the partition from Windows 10.

When I am trying to install using the live CD, I can only see the disk as a single drive and not seeing all the partitions. I am not sure what is wrong. Is it something related to my partitioning?

I need to use the J drive to install ubuntu 14.04 and I drive for 16.04.

Partition table entries are not in disk order

• Gparted is showing the disk with unallocated sign. [
• I merged one of the drives with the C drive. The left unused empty drive is NTFS with about 115 GB on which I wish to install Ubuntu 14.04.

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.

Does anyone know how to fix this?

nm-applet always gives me a hard time when connecting to wireless. I often have to restart it and make several attempts till it connects to a network. Sometimes even restarting the computer doesn't help. This time I ran it from CLI and I got this:

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.

After upgrade to 13.10 my bluetooth stoped to work: - I don't see bluetooth indicator at all - I am not able to turn it on and serch for devices

I've already checked some fixes like - instaled fixed a bazaar fork indicator-bluetooth - added my user to bluetooth group

Below are some outputs that show my config / issues

I am stuck with this weired issue. I am running Ubuntu 12.04

Sudo dpkg --audit

Output is

The following packages have been unpacked but not yet configured.
They must be configured using dpkg --configure or the configure
menu option in dselect for them to work:
network-manager-dbg:i386 network management framework (debugging symbols)
network-manager:i386 network management framework (daemon and userspace tools)
network-manager-gnome:i386 network management framework (GNOME frontend)

Not sure what to do.

I have also tried apt-get -f install

Output is

The following packages have been unpacked but not yet configured.
