Unable to access BIOS setup https://askubuntu.com/questions/1564779/unable-to-access-bios-setup

I installed Ubuntu 24.04.4 LTS on a computer (Intel® Core™ i7-3770, American Microtrend BIOS). At that time I could easily access BIOS. Computer was installed with WIndows 10. I boot pressing F2 key to access BIOS and install from USB key.

I'm now trying to install Ubuntu 25. But it's not longer possible to access BIOS. Pressing ESC or F2 during startup ends to black screen.

Installed Ubuntu version can still boot. But impossible to display BIOS to install a new version. I tried different screens on different connectors with same result.

Dialog file selector for specific types of files https://askubuntu.com/questions/1564774/dialog-file-selector-for-specific-types-of-files

I'm making a bash script using the dialog package to launch the various Windows programs via Wine, so I don't have to go around hunting for these files. In this launcher I also want to add an option for selecting a file on my computer, and while I found a function in dialog known as fselect which would work well, I cannot find any information online telling me how to make it filter to only select Windows Executable Files, .exe and .msi. If anyone knows how to filter it or a working workaround for this problem I would appreciate it.

How do I resolve my dummy output problem? https://askubuntu.com/questions/1564771/how-do-i-resolve-my-dummy-output-problem

I've been running Ubuntu 24.04 on my Dell XPS13. I can't get the internal speakers to work. The Intel CM238 HD chip is correctly identified, but the Sound menu keeps showing Dummy Output, and I get no audio. I've run pretty much every solution I've seen posted, and it hasn't helped.

Yesterday I tried going back to 22.04 and encountered something weird. When running it live off a USB stick, the speakers worked and were listed in the Sound menu, but once I actually installed it and rebooted, it went back to Dummy Output. What changes in the operating system when I install it instead of running it live?

DPKG: installing .deb package, unmet libxml2 dependency (but software works), how can I fix or ignore the unmet dependency? https://askubuntu.com/questions/1564761/dpkg-installing-deb-package-unmet-libxml2-dependency-but-software-works-ho

I can work from home via Parallels Client (a remote work package), but installing it leaves me with an unmet libxml2 dependency, however the software works fine, but apt keeps complaining and blocking on other installs/updates. How can I fix this?

To install Parallels (RASclient), I have followed the installation instructions from https://kb.parallels.com/en/123304:

IIVQ@Otto:~/Downloads$ sudo dpkg -i RASClient-21.1.26543_x86_64.deb

(first time I ran this I had multiple unmet dependencies, all of which I could install using apt, except for libxml2)

Trying to install libxml2:

IIVQ@Otto:~/Downloads$ sudo apt-get install libxml2

This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'libxml2' has no installation candidate

The Parallels software now works fine.

However, everything I try to do with Apt blocks with an You might want to run 'apt --fix-broken install' to correct these message. If I do that, it does "fix" the install by removing Parallels (RASClient):

iivq@Otto:~$ sudo apt --fix-broken install

Continue? [Y/n]

This could work as a workaround (removing parallels everytime I want to update/install something), but I'd rather have it fixed, or if that fails, ignored, as the Parallels client works fine.

This is on a laptop with a fresh Kubuntu 25.10 install. I have installed Parallels client on my desktop a year or so ago, also via .deb package, but it gave and gives me no problems at all. That desktop now runs Kubuntu 25.10 but is upgraded all the way from I think 2016.10, so it might be that libxml2 is still available somewhere on that machine?

Resetting Ubuntu using `dconf reset -f /` to default deletes what exactly? https://askubuntu.com/questions/1564759/resetting-ubuntu-using-dconf-reset-f-to-default-deletes-what-exactly

Extreme noob here, some time ago to try and solve a problem I followed a tutorial here that I probably shouldn't have so I thought of resetting since I don't have anything important on ubuntu. Online if you look for it you find this:

To reset Ubuntu to its default settings, you can use the terminal command dconf reset -f /, which will restore all settings to their original values. Remember to back up your current settings first, as this action cannot be undone without a backup.

I don't mind losing the files I have on Ubuntu but I don't know whether it'll affect anything outside my Virtual Machine on my Windows computer. As such I'd like to ask whether that's the case.

Apologies for my awkward prose, English is not my first language and thanks in advance.

Audio only works for one program at a time https://askubuntu.com/questions/1564590/audio-only-works-for-one-program-at-a-time

I have no idea why. I first tried it with Furnace, a music tracker, and a version of Discord. I have to choose between making music and talking with friends, or between a Discord call and a YouTube video. In addition to that without closing every other program using audio, a YouTube video won't even load.

I have no idea if it's PulseAudio, ALSA, JACK, PipeWire or anything else, nor do I know which of those I have installed, what they do or even what they are. I'm still a noob when it comes to Linux, but I got Kubuntu on my main PC I can't access right now, and it all just works (except the Nvidia GPU but that's for another day).

I'm also wondering just what each audio back-end does, which I can remove with apt and not break half my packages, and which is enabled by default when I start up my PC.

I'd like everything to just work so I can have multiple programs sending audio to my headphones without having to input any commands to Konsole on startup.

UPDATES: Additional Info I'm on Kubuntu 25.10, x64, my Linux Kernel is 6.17.0-14-generic, and my specs are as follows: Intel Core i5-8400 CPU Intel Arc B580 GPU, Kisak PPA Mesa drivers 16 GB DDR4 RAM KDE Plasma 6.4.5. (Accidentally typed 6.27 instead of 6.17 for the kernel version)

I ran pw-top, here's my output (Apologies for the formatting, it's a direct copypaste from Konsole.) Dummy-Driver S 31 0 0 --- --- --- --- 0 Freewheel-Driver S 45 0 0 --- --- --- --- 0 Midi-Bridge S 48 0 0 --- --- --- --- 0 bluez_midi.server S 78 0 0 --- --- --- --- 0 alsa_output.usb-Razer S 79 0 0 --- --- --- --- 0 alsa_input.usb-Razer_ The device I want to have everything go through is my Razer USB Sound Card (no mic attached so Output).

Pactl-info works, but pacmd says there's no daemon running. And I can play a YouTube video from both Chromium and Waterfox and hear both at once.

Ubuntu 24.04 freezes with "nvme nvme0: I/O" timeout error https://askubuntu.com/questions/1557696/ubuntu-24-04-freezes-with-nvme-nvme0-i-o-timeout-error

I am running Ubuntu 24.04.3 LTS (codename "noble") in an ASUS Vivobook 15. My kernel version is 6.14.0-33-generic according to the output of uname -r.

Ever since I got this laptot, my Ubuntu system would sometimes "randomly" freeze. This would occur rarely enough that it didn't represent a problem. However, today I exeperienced an annoying sequence of repeated freezes which got me looking into the problem more closely.

I ran dmesg -w and waited for the computer to freeze. It eventually did, precisely after the following output:

nvme nvme0: I/O tag 4 timeout, aborting req (WRITE), QID 7, size 4096
nvme nvme0: I/O tag 7 timeout, aborting req (WRITE), QID 7, size 4096
nvme nvme0: I/O tag 9 timeout, aborting req (WRITE), QID 7, size 4096
nvme nvme0: I/O tag 4 timeout, aborting req (WRITE), QID 0, size 4096
nvme nvme0: I/O tag 10 timeout, aborting req (WRITE), QID 0, size 4096

So it seems the freezing was triggered by an error in a write operation of 4KB. I found two other people with this issue (1, 2), but their final solution was to change the SSD, which is not economically viable for me.

After a force shutdown (the only way to handle the freezing), I ran sudo dmesg -T | grep -i nvme -n -A5 -B5, since the issue was comming from nvme. The boot section of the output looked normal:

nvme nvme0: pci function 10000:e1:00.0
nvme nvme0: allocated 64 MiB host memory buffer (1 segment).
nvme nvme0: 8/0/0 default/read/poll queues

I tried changing the GRUB_CMDLINE_LINX_DEFAULT from

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash

to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvme_core.default_ps_max_latency_us=0"

to be frank simply because ChatGPT recommended it (I know this is embarassing). This only caused freezings to become worse, so I undid it.

Now I've changed GRUB_CMDLINE_LINUX_DEFAULT to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=off"

because in one of the hyperlinks I gave above someone recommended it. I have not experienced any more freezes, but it's only been a couple of hours so the issue might continue.

In case it's useful, here's the output of sudo smartctl -a /dev/nvme0:

nvidia-smi is not working on 24.04 https://askubuntu.com/questions/1544494/nvidia-smi-is-not-working-on-24-04

I have a NVIDIA GeForce RTX 5070 Ti on my lab PC running Ubuntu 24.04, and I am trying to install the nvidia drivers. I tried looking up the Additional Drivers in the Software & Updates, but nothing shows up there. I also tried sudo ubuntu-drivers list and sudo ubuntu-drivers devices. Both of these commands give no output so I installed the NVIDIA driver using the command - sudo apt install nvidia-driver-550. After this, when I run nvidia-smi, it shows me the following error:

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver.   
Make sure that the latest NVIDIA driver is installed and running.  

When I run lspci -v, one of the output is:

The GPU is detected which was my initial fear, but I don't know why there are no additional drivers that need to be installed. Also how do I get the drivers to work then?

What does the efibootmgr timeout value affect? https://askubuntu.com/questions/1525866/what-does-the-efibootmgr-timeout-value-affect

The efibootmgr help output states:

-t | --timeout seconds set boot manager timeout waiting for user input.

But where does this timeout and user input occur?

It doesn't appear to affect boot managers like GRUB or rEFInd, which have input and timeout parameters in their own configuration files. It also doesn't seem common for a motherboard BIOS to show a boot selection options with a timeout (they typically either boot automatically to the first available option, or allow selection without a timeout if the setup utility is manually invoked).

Is this an outdated option or is there some firmware or software whose behaviour is controlled by this parameter?

How to get ipu6 webcam (XPS 14 9440) to work on Meteor Lake platform? https://askubuntu.com/questions/1508977/how-to-get-ipu6-webcam-xps-14-9440-to-work-on-meteor-lake-platform

I try to get the webcam on a XPS 14 9440 on Ubuntu 23.10 to work. Since the notebook is Meteor Lake based, I've to use a current kernel (>= 6.7) to get proper Meteor Lake support. I use 6.8 mainline kernel.

$ uname -a
Linux christoph-XPS-14-9440 6.8.1-060801-generic #202403151937 SMP PREEMPT_DYNAMIC Fri Mar 15 19:52:22 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

Unfortunately there are no prebuild IPU6 drivers available for kernels >= 6.7, because there are at this point in time (29. March 2024) open PRs (https://github.com/intel/ivsc-driver/pull/44, https://github.com/intel/ipu6-drivers/pull/213) that are required to make them work on current kernels.

How can i get the drivers properly working?
It's totally confusing for me what all the things do and how they work together to get the webcam working. I mainly just followed the readmes without much knowledge how everything is connected. So while ipu6 are the actual drivers, what is icamera, IPU6 HAL and how is it all connected to Gstreamer to get the webcam work in applications?

So I tried to compile it on my own and it worked successfully with the ipu6-drivers (incl. ivsc-driver). They are compiled and loaded successfully, as far as i can see.

However, as far as I understand I've to additionally compile ipu6-camera-hal including icamerasrc (https://github.com/intel/ipu6-drivers) to get the webcam actually working in applications (Google Chrome would be most important for me).
I cloned https://github.com/intel/ipu6-camera-hal and placed it beside the icamerasrc_slim_api branch of the icamera repo as it's mentioned in the readme.

When I now try to run build.sh it seems to successfully build ipu6-camera-hal but fails on icamerasrc.

I had similar issues before, but for them I could find missing packages that I had to install to provide the missing libs. But in that case I can't find how to solve it.

Ubuntu 20.04 - Static and default routes via netplan https://askubuntu.com/questions/1450620/ubuntu-20-04-static-and-default-routes-via-netplan

I am brand new to Linux. I only started 'playing' yesterday, so please forgive my lack of knowledge. I have built a linux server with 2 network cards. Outside interface (ens192) for all Internet traffic and an INSIDE interface (ens160) for all internal traffic. All interfaces are STATIC. I would like a single default route to be on the OUTSIDE (ens192) I would like to route all other networks INSIDE (ens160)

Please see below what I have attempted to build so far.

network:

ethernets:
  ens160:
      dhcp4: no

      - to: 172.17.10.0/24
        via: 172.24.0.5

I am currently receiving this error - /etc/netplan/50-cloud-init.yaml:15:1: Invalid YAML: tabs are not allowed for indent: - to: 172.17.10.0/24

I have received this error with a previous configuration.

** (generate:5240): WARNING **: 10:16:53.463: Problem encountered while validating default route consistency.Please set up multiple routing tables and use routing-policy instead. Error: Conflicting default route declarations for IPv4 (table: main, metric: default), first declared in ens192 but also in ens160

I am at a complete loss on what to do here.

Please help.

After a few minutes of audio/video playback computer starts beeping - 21.10, Asus T100TA https://askubuntu.com/questions/1393842/after-a-few-minutes-of-audio-video-playback-computer-starts-beeping-21-10-asu

Whenever I play audio from various apps, like Spotify, or any browser (I checked Firefox and Tor), the computer starts beeping after couple of minutes. The beeping stops only when I stop playback. I also checked if it appears when I plug in 3.5 mm jack headphones and it does. Before 21.10 I was using 20.04 LTS and there were no audio issues there. There is a similar question raised in regards to ASUS T102HA, but since I am a new user I am not allowed to add comments there. I wanted to run sudo sensors-detect according to what was suggested there, but the app started to ask me about loading various kernel modules, so at some point I just opened built in resources monitor. Please see the screenshot attached. CPU load was around 50% when the beeping started and it raised to 100% until I killed the process. My machine - ASUS T100TA

Ubuntu Server 20.04 install ends with a kernel panic https://askubuntu.com/questions/1376857/ubuntu-server-20-04-install-ends-with-a-kernel-panic

I've been trying to install Ubuntu Server from a fresh ISO and a USB drive that I know works (It has been used to install Ubuntu on other machines). When I boot from the USB drive, I get a purple screen with a few icons at the bottom, followed by a kernel panic message.

Picture in Picture mode https://askubuntu.com/questions/1289784/picture-in-picture-mode

I switched from Elementary OS to Ubuntu last week. I miss Picture in Picture mode which Elementary OS offered. Picture in Picture mode in Elementary OS puts any part of the screen in PiP mode. I could put anything in Picture in Picture mode. Is there a way to get it in Ubuntu?

Keyboard not working in games in Wine https://askubuntu.com/questions/1065391/keyboard-not-working-in-games-in-wine

I've installed GoG Heroes III Complete using Wine on Ubuntu 18.04 on an Acer Aspire TimelineX 5830TG laptop. When running the game, I see that some keyboard shortcuts won't work. For example, n to select New Game, r to select Random Mode, e to end turn, t to select city. However, Esc works to exit game, and Enter works for confirming selection.

I've stumbled upon this thread here: keyboard not working with games in wine which I hoped will help me, but after following it closely I had no luck.

I've tried changing Windows version in winecfg from XP to 7 to 8 to 10, but nothing happened.

I've tried switching Ubuntu's native input method from default to ibus and back, also with no results.

Any hope I fix this?

Using Hp Smartarray P400 with Ubuntu https://askubuntu.com/questions/1030730/using-hp-smartarray-p400-with-ubuntu

I have recently been trying to install Ubuntu 18.04 on my ProLiant DL380 G5, which is using the RAID card Smartarray P400. When installing the desktop version, it wouldn't detect any hard drives, (whereas the latest Debian did but had DCHP problems) so I tried the RAID/Alternative Server version (which, after realising that this version is CLI only I don't want to use anymore). This, however, did not detect any storage either.

From what I have gathered, the P400 uses the ciss driver, which I believe has been replaced with hspa.

In the server version where it asks you to select a driver from the list after it fails to recognize storage, I attempted to use the hspa driver but this failed.

Any help on how to install Ubuntu (even if it's an old version) would be greatly appreciated.

possible to mark all mail as read using one line terminal? https://askubuntu.com/questions/994498/possible-to-mark-all-mail-as-read-using-one-line-terminal

I am not trying to remove all the mails.

I googled for mark all mail as read, actually got posts saying how to delete them instead.

I found out using echo p | mail will output first of unread then mark it read, but if I do this, I have to loop through them.

I figured for all read mails, they will be appended to a file named mbox

What I am trying to do is...I want to create a bash file which is then used for crontab that let's say, at the end of each month, change the name of mbox into month-year in this way I can keep track and organize the mails BUT in order to have the mails appended into mbox is reading the mails one by one first.

Am I thinking this in a wrong direction? Or can someone give me some advices?

Thanks in advance for any help

EDIT: I am just using sudo apt install mailutils for my ubuntu server

Install openssh-server package from preseed file https://askubuntu.com/questions/935565/install-openssh-server-package-from-preseed-file

So I've managed to create a custom ISO using a preseed file that isntalls the OS automatically, all works fine BUT the isntallation of the openssh-server package...I'm not what else to do.

On my preseed file I have the following lines:

#Add package
d-i pkgsel/include string openssh-server build-essential

however when I login,the package has not been installed. I also need to enable to login with root, for other purpuses so I need to modify the sshd_config file, I have tried the following two options also but I guess they don't work because the openssh-server package doesnt install on the first place:

ubiquity ubiquity/success_command string sed -i '/PermitRootLogin/c\PermitRootLogin yes' /etc/ssh/sshd_config

and

d-i preseed/late_command string sed -i '/PermitRootLogin/c\PermitRootLogin yes' /etc/ssh/sshd_config

What is the best way to first, add the ssh server package? and then modify the sshd_config file? so when the OS boots the ssh service is started and running

How to set grub from second Linux distribution as default in UEFI boot? https://askubuntu.com/questions/792413/how-to-set-grub-from-second-linux-distribution-as-default-in-uefi-boot

I’m dual booting two Ubuntu Linux distributions. There was made only one boot entry for both of them:

Boot000A* ubuntu

Since the second one (not often used) was installed after my primary distro (used daily), kernels are not automatically updated within that distro through “sudo update-grub”. I have to login to other ubuntu distro, type “update-grub” to be able to use newly updated kernels from my primary distro.

How can I make my main ubuntu distro’s grub entry to be default one and not secondary (UEFI) ?

target filesystem doesn't have requested /sbin/init. /bin/sh: 0 : Can't open splash - Ubuntu 15.04 https://askubuntu.com/questions/727810/target-filesystem-doesnt-have-requested-sbin-init-bin-sh-0-cant-open-spl

I have an Ubuntu 15.04 machine. I installed docker in this machine. After installation I was trying to run the test image of docker which comes by default. But it did not ran. Then I tried to shutdown the machine.

But the machine was not shutting down. It just hanged in the middle and was consuming all of the cpu resources. I waited for 10-15 mins but state did not change and nothing happened. So I went ahead and shutdown the machine by pressing the power-on button in laptop for a while. This way the machine went off.

After this event, now when I am trying to boot into the machine, it is throwing me following error at the time of boot.

Target filesystem doesn't hvae requested /sbin/init.
/bin/sh: 0: Can't open splash

Machine has three os: Windows, Centos, Ubuntu-15.04.

I have tried the fsck solution on the boot device with network boot. But it does not solve this problem.

Here I don't know if docker package is part of the problem. It could have been any package installation for that matter.

The output of fsck is as follows:

I have also tried -f option of fsck, output for that is:

 
$ fsck /dev/sda5 -f
fsck /dev/sda5 -f
fsck from util-linux 2.25.2

Running fdisk -l command prints following message, along with printing device details.

Partition 5 does not start on physical sector boundary.

I mounted the device using mount -o ro /dev/sda5 /media/boot command. And the output of ls -l /media/boot is as follows:

freetuxtv installed in 14.04 is not working https://askubuntu.com/questions/459962/freetuxtv-installed-in-14-04-is-not-working

I have installed freetuxtv and it went through the preferred language and installed my program list.

I tried an outdoor channel and it said "playing" but also showed an error message saying that the channel may be dead. I tried all the channels with the same result.

I reinstalled tuxtv and vlc again and also checked my flashplayer to see if it was installed with no joy.

How can I fix this?

kernel panic - diagnosis? https://askubuntu.com/questions/195806/kernel-panic-diagnosis

I'm having a kernel panic problem. My machine will run for hours, maybe all day and then have a kernel panic. I have no idea how to interpret these boot messages.

I've looked through the logs, but didn't find anything obvious. I'm still learning, so I probably missed something. It's a little harder since it's always happened when I've been out or at night, so I can't pinpoint the exact time when it crashed.

Live CD kernel panic https://askubuntu.com/questions/7256/live-cd-kernel-panic

I'm an Ubuntu user since Hardy Heron, and even in other distros I've never been through such thing. I can't install Ubuntu 10.10 on my notebook, because I simply can't even start the Live CD. I always get the following message:

Kernel panic - not syncing attempted to kill init!

See the complete message:
