I want to integrate windows 11, Linux, ai and Android onto 1 OS system for my pc

On Win11 I used Rufus to create a 25.10 USB stick from a verfied .iso image (generated a good checksum). I insert the stick into my former Win7 (working) tower, ASRock Z68 Extreme7 Gen3, 16GB RAM, Intel i7 4 cores, 3.5GHz. I press F11 on boot. I see the USB stick, tell it to boot from the stick, it immediately shows a GNU GRUB v2.14 screen with 3 choices. 3rd choice works... I can test memory (all good). When I select either of the other 2 choices: 'Try or Install Ubuntu' OR 'Ubuntu (safe graphics)' it immediately goes to a black screen with a little flashing under-cursor. I have waited at this point multiple times for over 10 minutes, nothing seems to be going on. Any ideas how to trouble shoot this? Would there be any logs on the USB stick at this point? If yes, where? I have tried 3 separate USB ports, same results. My system has dual monitors, the same black screen, little blinking under-cursor on both screens. Should I switch to a single monitor and connect it to the video port provided on the motherboard instead of the two video ports on an add-on card? Thanks for any/all suggestions.

PS - the iso image name I used is 'ubuntu-25.10-desktop-amd64.iso' it bothers me that it as 'amd64' in the name even though I am certain I downloaded the image that is for the Intel 64bit.

AFter througgh many searches i found you cannot avoid secure boot disable for ubuntu install. However I feel it may not the case. signed ubuntu iso images should get sign keys in laptop efi firmware. I am confused if it is one universally used or every new version gets new key and how does it get to laptop bios unless in windows i should get efi utility to add keys. Pls guide. I do not want to disable secuure and install ubuntu. Basically i lost password for ubuntu and i need to get installation iso to get to root drive where i can modify shadow file to get uvuntu. My ubuntu is 22.04 lts. How to achieve secure boot for to install ubuntu? ubuntu boots in secure mode except installation iso has difference.

Currently using the Resolute Raccoon branch for testing and bug reporting. Normally I just use the flatpak version to install Minecraft, but I wanted to try the official deb package, but when trying to install it, I got the follow error:

scott@ubuntu:~/Downloads$ sudo gdebi Minecraft.deb
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Reading state information... Done
This package is uninstallable
Dependency is not satisfiable: libgdk-pixbuf2.0-0 (>= 2.22.0)

I assume there is nothing I can do to resolve this? But curious if there is any fix, workaround, or if maybe I need to file a bug report for this? Appreciate any help, thank you. Loving 26.04 btw (feels very much like 25.10!)

I also got this error trying to install a different way. Looks like maybe I just have to watch until 26.04 becomes more stable.

scott@ubuntu:~/Downloads$ sudo apt install ./Minecraft.deb
Note, selecting 'minecraft-launcher' instead of './Minecraft.deb'

I have an Assus Zephyrus S 502GW laptop with Windows 11, UEFI BIOS ver 312. Cannot find an option to enable AHCI in BIOS therefore my internal SSDs (NVMe) are not visible to the installer.

Any idea on how to enable AHCI? It seems stupid to build a BIOS this way but before selling/throwing the machine maybe there is a solution somewhere? Cannot find a newer BIOS version.

Thx.

I'm having - recurring - problems with my Acer Aspire A325-42, with AMD Ryzen™ 7 7730U with Radeon™ Graphics × 16, running Ubuntu 24.04.3 LTS. When tried dmesg on command line, get a whole bunch of ACPI errors: several ACPI-related errors, particularly:

• ACPI Error: Aborting method \_SB.PCI0.SBRG.H_EC._REG due to previous error (AE_AML_BUFFER_LIMIT)

• ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [N457] at bit offset/length 32/32 exceeds size of target Buffer (56 bits)

I can't figure any way to copy/paste between a Ubuntu 25.10 host and a KVM/QEMU Windows 11 guest. As a first step, I'd be happy to copy/paste text only, though I wouldn't ignore solutions that allow for more general copy/paste, including file drag/drop solutions. However, nothing I've found online works, including installing the spice guest tools on the guest. The VM is defined with virt-manager and uses defaults for everything but the network (bridge not nat). The VM works fine, except no copy/paste. Can anybody help? Note that:

• VMs defined with virt-manager already use the spice display and the QXL video by default. Thus the solutions that suggest turning on these features are ineffective or not applicable
• I'm using virt-manager to define the VM. Thus the solutions that involve specific parameters for the CLI version of QEMU are not applicable.
• Several online suggestions discuss editing XML or YAML files that don't seem to exist under Ubuntu 25.10. These are also N/A.
• The Windows version is a non-activated version of Windows 11, completely up to date. The only differences I've seen between an activated and an un-activated install of Windows involves personalization settings (colors, themes, ...). In particular, copy/paste works fine within the guest and works fine via remmina, just not with the KVM/QEMU console.
• The copy/paste I really need isn't app specific, on either the copy or the paste side. Regardless of the app, text that's copied can be pasted into other apps, including the VM if I access it via remmina, but it can't be pasted into the standard KVM/QEMU console. I'd prefer the console, only because it's a slight pain to have to run remmina in addition to virt-manager. Note that, until it broke, VirtualBox supported full bidirectional copy/paste with the addition of the appropriate host and guest extensions. However, I can't stand the somewhat flaky nature of VirtualBox wrt Ubuntu-hosted VMs, so I'm looking for a solution closer to a standard Ubuntu install.

I'm trying to PXE-boot and install Ubuntu 25.10 Desktop from our local DHCP/TFTP server and using a local web mirror with the ubuntu-25.10-desktop-amd64.iso image. This is the menu entry in grub.cfg from the TFTP-server:

menuentry "Install Ubuntu 25.10 Desktop" {
        set gfxpayload=keep
        linux   (tftp)Ubuntu-25.10-amd/amd64/linux iso-url=https://<web-server>/ubuntu-25.10-desktop-amd64.iso ip=dhcp ---
        initrd  (tftp)Ubuntu-25.10-amd/amd64/initrd
}

The boot process loads the linux kernel and the ISO image, but then fails with the message Unable to find a live file system on the network, presumably when trying to load the initrd.

The usual google results about bad setup of the TFTP server don't seem to apply. If I use the ISO image ubuntu-25.10-live-server-amd64.iso in grub.cfg in stead, the Ubuntu server installation works perfectly! So what's wrong with the Desktop image?

FYI: The PC being installed is an older HP desktop with 16 GB RAM, so there should be plenty of memory. The PC is configured with UEFI Secure Boot.

I have a very old laptop so every speedup counts and I want LibreOffice DEB instead of Snap under Ubuntu 25.10.

As per https://wiki.ubuntu.com/LibreOffice I run sudo apt install libreoffice but I get the following error message:

Error: Unable to satisfy dependencies. Reached two conflicting decisions:
   1. libreoffice:amd64=4:25.8.1~rc1-0ubuntu1 is selected for install
   2. libreoffice:amd64 Depends libreoffice-draw
      but none of the choices are installable:
      - libreoffice-draw:amd64 Depends libreoffice-uiconfig-impress (= 4:25.8.1~rc1-0ubuntu1)
        but none of the choices are installable:
        - libreoffice-uiconfig-impress:amd64=4:25.8.1~rc1-0ubuntu1 is not selected for install

It's a freshly installed system! how to install libreoffice in DEB form? without resorting to the libreoffice PPA which is explicitly not recommended for end users, being the packages too fresh?

I am trying to host a very simple web page.

I created a new landing page and renamed it index.html and it loads.

I have a few simple references to additional pages.

<a href="File-Path">Name</a>

These referenced pages will not load.

I attempted to make additions to the .conf file with no success.

How do I add additional pages and have them load off of a reference on the index page.

Index with references to example1.html, example2.html, example3.html

All of the html files are in the same folder I believe the path is /var/www/html/Folder with all my pages

I changed the .conf file to point to that folder to load the index.html

1. I have a mail-in-a-box server v73 running on Ubuntu 22.04
2. It runs postfix, used to send emails out (outgoing) to gmail.com for example
3. I know the status is sent because of the logs above and the code 250 from the /var/log/mail.log
4. I'm already able to handle bounces from GMail (incoming) by configuring a pipe in master.cf to a script
5. Is there a similar way I can config postfix to call another script about the 250? (I prefer not to be constantly scanning the logs)

I’m trying to run Ubuntu 25.10 on a 2013 Mac Pro (“trashcan”, MacPro6,1) with the stock dual AMD FirePro D500 GPUs (Tahiti / Southern Islands).

Ubuntu installs and boots only when I use:

quiet splash nomodeset

Without nomodeset, the system freezes during early KMS initialization.

When booting without nomodeset, the kernel logs consistently show:

[drm] amdgpu kernel modesetting enabled.

amdgpu 0000:02:00.0: probe with driver amdgpu failed with error -22

amdgpu 0000:06:00.0: probe with driver amdgpu failed with error -22

This happens regardless of SI switching options, including:

radeon.si_support=0 amdgpu.si_support=1 amdgpu.dc=0

radeon.si_support=1 amdgpu.si_support=0

linux-firmware is fully up to date. No blacklisting of amdgpu/radeon is present. EFI hands off a framebuffer, and the system runs using simpledrm only.

Other observations:

/sys/kernel/debug/dri/* contains only simpledrm nodes.

Both GPUs appear in lspci and iommu grouping without errors.

No IOMMU/DMAR faults.

The amdgpu probe fails immediately with -22 before any ASIC init.

My question:

What does probe‐time error -22 typically indicate for Southern Islands (D500 “Tahiti LE”) hardware, and is there a known requirement or quirk for MacPro6,1 dual GPUs under recent kernels (6.17.x)?

Any guidance on whether I should be forcing radeon instead of amdgpu, or whether the dual-GPU Apple PCI layout requires special quirks, would be very helpful.

I ran sudo apt install nvidia-driver-550 and it appeared to install the driver correctly. The "System Details" screen still shows it using Intel graphics. I tried prime-select nvidia and it appeared to work but running sudo nvidia-smi returns an error message "NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running."

So I assume the driver is installed but not running. Running Nvidia settings does open the settings windows but also throws multiple terminal errors. (I'm not typing all that I'm gonna take a picture with my phone.)

I have exhausted every solution that Google had offered me, I just want to use the GPU that is in the laptop that I own. Please help me Linux computer geeks, I cannot do this.

Edit: Okay so it appears the question is lacking important information.

Is this helpful? Also this is indeed an older version of Ubuntu. I didn't realize it was when I installed it. (24.04.3 LTS)I just ran the Ubuntu that Google provided yall. Is fixing this problem as simple as installing the latest version of the OS?

Edit 2: Okay I was restarting it to try and get into the BIOS and it gave me this message:

"The NVIDIA GeForce GTX 765M GPU installed in this system is supported through the NVIDIA 470.xx Legacy drivers. Please visit http://www.nvidia.com/object/unix.html for more information. The 580.95.05 NVIDIA driver will ignore this GPU. Continuing probe..."

I tried installing that 470 driver instead with sudo apt install nvidia-driver-470 and was met with yet more error messages.

Now what?

can't power down ubuntu 24.04 lts with shutdown button it reboots on my HP probook 450 G9

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 recently installed Ubuntu 24.04 and I'm having a serious problem when trying to use dark mode.

I know there seems to be an issue with NVIDIA proprietary drivers... but when I set Nouveau opensource driver - instead of NVIDIA proprietary own drivers - my dedicated NVIDIA Graphics Card doesn't seem to work... although then the dark mode seems to work.

So I keep having to choose, either set the dark mode or set my graphics card to work, which is awful.

The dark mode partially works for some apps but not for others: it doesn't for Files, Calculator, Settings, etc.

When I change the PRIME profile to Performance Mode, the computer gets a lot lazier to start the system and open apps, initially the dark mode keeps light, and then, eventually, turns out to work ok, but the computer gets too slow.

What do I want ?

I want to be able to use the latest NVIDIA proprietary graphics card driver, use either of both PRIME profiles available, and have the dark mode to work fine for all apps... without making my notebook get slow.

Is that possible ?

PS.:

1. I've already set gtk-application-prefer-dark-theme=1 at settings.ini at gtk-3/4 folders at ~/.config, it didn't work;
2. I've tried to add gtk-application-prefer-dark-theme=1 to my .profile, to load on boot, but it also didn't work;
3. I tried exporting the env variable GTK_THEME=[THEME_NAME], at my .profile, and that kept the dark mode black (on both PRIME profiles, for all apps), but messed badly with the line-heights at the Files... and at other softwares as well, including the Calculator, so I had to undo that...
4. The only partial solution up until now is to set the PRIME profile to Performance Mode and deal with a lot more slow system - the dark mode then works.

THANKS to anyone who might have a solution...

I am aware of the 24.04.1 troubles at roll out.

Earlier this year I set up a fresh Jammy LTS Ubuntu instance on a new computer. I waited with the upgrade until a few days ago when it prompted me to upgrade to Noble. I thought any and all kinks were ironed out, especially since this is a very vanilla hardware (and software) environment. Anyway some things broke:

When I run Software Updater now, sometimes the application crashes, sometimes it'll report this:

I go for "Partial Upgrade", which quickly throws this error message:

Now I'm new to Ubuntu, but even I know the order in this error is wrong. I can't resolve this going apt update & apt upgrade. Some other things broke as well. ie: double clicking on an encrypted file within a zip (default will no longer prompt for password input, I have to manually extract the respective files. Just weird. Do you have any ideas for me as to how I can restore the updater?

The single piece of software I installe from outside of Ubuntu's own snap basket is SABnzbd.

673 packages can be upgraded. Run 'apt list --upgradable' to see them.

then, if I run sudo apt upgrade, none of said packages are upgraded.

I checked against Major software missing after 24.04.1 LTS upgrade and when I follow the instructions there to fix /etc/apt/sources.list and /etc/apt/sources.list.d/ubuntu.sources, I find that /etc/apt/sources.list contains only noble and no jammy BUT there is no /etc/apt/sources.list.d/ubuntu.sources file.

So I cd to /etc/apt/sources.list.d/ and ran dir.

It contains: jcfp-ubuntu-nobetas-jammy.list, jcfp-ubuntu-nobetas-jammy.list.save, and jcfp-ubuntu-nobetas-jammy.list.distUpgrade.

I have a 2022 HP 14" Spectre x360, which can flip into tablet mode and has an accelerometer to switch the screen orientation. However, when I installed Ubuntu 22.04 on it, I found that switching it in or out of tablet mode, switching the orientation of the screen, or closing or opening the lid all toggle airplane mode.

This seems to be a relatively common problem for HP laptops (although my previous Spectre never experienced it). There is a fix for found in the first answer to this post, but unfortunately it doesn't seem to work on my system.

This fix relies on setting the keycodes for both the "close lid" and "orient" actions (e057 and e058 respectively) to the "KEY_UNKNOWN" keycode (240). My theory as to why it won't work for my system is because for some reason either my new laptop, or Ubuntu 22.04 has changed the action IDs for closing the lid and changing the orientation. I tried to figure out the new keycodes using xev, but switching orientation/tablet mode didn't show anything, and closing the lid gave output I didn't find helpful (seen below):

It starts with several key IDs, but changing any of them doesn't fix the problem.

So I guess my question is what's the best way to figure out which key IDs to set to 240 in order to prevent airplane mode when changing my laptop screen.

I recently upgraded to Ubuntu 21.10 and the audio pipes through only the monitor. I have tried playing around in pavucontrol and this is what I see

Here is the output from the terminal

$ cat /proc/asound/cards

Any suggestions how to set the audio to come from line out. Even when I manually select Line Out from the system settings, audio comes via only the monitor.

I have a docker container that has published port 3001. I can connect to the docker container by pinging it from the host

$ netcat -vzn 0.0.0.0 3001
Connection to 0.0.0.0 3001 port [tcp/*] succeeded!

But from the outside of the host, I get connection refused.

$ netcat -vzn 10.0.0.154 3001
netcat: connect to 10.0.0.154 port 3001 (tcp) failed: Connection refused

The docker container has published ports:

PORTS
0.0.0.0:3001->3001/tcp, :::3001->3001/tcp

The host firewall has been disabled.

The host is a physical server running on Ubuntu.

The containers are not accessible even if running on the hosts network directly...

docker run -it -d -network=host ...

I've read all the documentation, and by every instruction, the containers SHOULD be accessible by hostIp:port with this current set up. I'm not sure if there's anything else I'm missing from Docker instructions, or there's something funky going on with the Ubuntu Server OS itself that is refusing these connections.

Any ideas? Thank you!

I am trying to use my android device as a webcam. I am using Droidcam and video is being shared properly. But I still have no voice. Ubuntu doesn't recognize Driodcam as a sound input device. I don't know what is causing the problem and how should I debug the process.

I am using Ubuntu 18.04 LTS dual booted with Windows 7 on HP Envy 15. After my laptop goes into sleep mode (lid closed) it will turn on airplane mode but the button to turn it off is greyed out and says "use hardware switch to turn off" and the only other switch is the Fn+F12 which doesn't work. It fixes itself on reboot but I was wondering if there was a way to prevent it. In Windows, it happens plugged in and on battery. Before sleep:

$ sudo rfkill
ID TYPE      DEVICE      SOFT      HARD
 0 bluetooth hci0   unblocked unblocked
 1 wlan      phy0   unblocked unblocked

After sleep:

$ sudo rfkill
ID TYPE      DEVICE      SOFT      HARD
 1 wlan      phy0   unblocked   blocked

I have tried blocking and unblocking it via rfkill but it doesn't work the only way that I have found to disable it is via rebooting.

I have two MacBooks. One installed Ubuntu 18.04 flawlessly. The other would hang on the Splash Screen for the intial install. So in the grub menu, I pressed 'e' and typed in nomodeset where applicable. That did the trick, and I was able to install Ubuntu. Then I updated the graphics to NVIDIA, rebooted, and now I'm getting a blank screen on boot-up. If I press option + command + r, I'm able to get to the grub menu again (not from the boot USB), and if I press e, I see that nomodeset is already there. I don't understand what to do at this point.

I also tried to start completely over, and press option + power to boot to USB, and my USB drive won't show up in the menu! I tried different USB drives, and same result.

I've seen a pro github link in the comments for the following question on how to get the Wi-Fi in Ubuntu 18.04 to work. Using the following command:

lspci | grep Wireless

I saw that my driver was rtl8188ee. Whereas my Wi-Fi does not work,connecting by cable works flawlessly. I used the following commands from the README from the github site:

sudo apt-get install linux-headers-generic build-essential git
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
sudo make install
sudo modprobe -r rtl8188ee

and it worked, but only once! After a reboot, typing:

sudo modprobe rtl8188ee

gives the following error:

$ sudo modprobe rtl8188ee
modprobe: ERROR: could not insert 'rtl8188ee': Exec format error

How should I proceed?

I connected an Xbox One controller to a PC equipped with Ubuntu 15.04 and the system recognizes it perfectly. The problem is that VirtualBox with Win10 (to stream Xbox games) fails to recognizes it. I also tried to install xboxdrv to see if something changed, but nothing. The pad works perfectly under Ubuntu, I have also tested it with jtest-gtk, but there's no way to do something to make VirtualBox working with it. After all, I have tried to create a USB filter on VirtualBox settings with the parameters taken from lsusb but absolutely nothing happens.

Any idea to make the Xbox One pad working under VirtualBox?

I'm behind a corporate proxy, and we have Windows PCs with root ca certs pre-installed so SSL works with the proxy. Within my PC, I'm spinning up Linux VMs for testing, and so I have a need to get those certs installed within the VM so I can hit whatever SSL URL I need (github cloning etc). I've tried a few methods to export the certs from Windows and import them into Ubuntu, but as of yet I am unable to access SSL from within the VM.

This answer gave me the best idea for what format to export the cert in from Windows (base-64 .cer). After I export the .cer files and copy them into place in the VM, I rename them with .crt extensions.

This answer best sums up what I'm trying in the VM.

After I add the certs to the usr/share/ca-certificates directory and run update-ca-certificates the certs do get symlinked into /etc/ssl/certs but still no SSL traffic.

This is on a Windows 7 host, Ubuntu 12.04 guest.

After I deleted my Ubuntu partition, I rebooted my computer and I only get a prompt:

grub rescue >

The command ls lists

(hd0) (hd0,msdos5) (hd0,msdos3) (hd0,msdos2) (hd0,msdos1) (hd1) (hd1,msdos1)

I check them one by one:

ls (hd0,msdos5)/
ls (hd0,msdos1)/

But I cannot find the right partition.
