I just installed Ubuntu. Why can't I play a video and just get errors?

A friend installed Ubuntu operating system on a Windows surface3 laptop I had. Im new to computers and dont know how to fix the non working web camera. And touch screen. Can use help with navigating other areas like movie down load and watching along side music. Thanks

For 26.04 I did an almost complete reinstallation of my system, only keeping my home drive but formatting all system drives.

I installed Thunderbird with apt, and it works fine with all my old settings and configurations.

But it doesn't show up in the applications menu... If I press the Windows key on my keyboard, searching for e.g. Vivaldi (my browser of choice) allows me to find and start it just fine, but Thunderbird does not show up. I have to start if from a terminal.

The /usr/share/applications/thunderbird.desktop file is there and seems to be fine.

I've logged out/in and restarted my computer multiple times to no avail.

Was something changed in regards to mail and/or Thunderbird in 26.04? Why can't I search for it?

As the title says, I just installed 26.04 on my MacBook Pro. WiFi does not work, but it's fixable as shown below:

The question is, why did I have to do so much manual work? This is not user-friendly.

After the fresh install, the WiFi didn't work. Looking at dmesg, I found this:

b43-phy0: Broadcom 4360 WLAN found (core revision 42)
b43-phy0 ERROR: FOUND UNSUPPORTED PHY (Analog 12, Type 11 (AC), Revision 1)
b43 bcma0:1: probe with driver b43 failed with error -95
Broadcom 43xx driver loaded \[ Features: PNL \]

A bit of Googling shows that problems like this have been reported by some users for years.

The ubuntu-drivers devices command suggested in some posts produces no output. (That's a user interface that needs some improvement).

On this MBP, lspci -nn -d 14e4: reports

03:00.0 Network controller \[0280\]: Broadcom Inc. and subsidiaries BCM4360  
802.11ac Dual Band Wireless Network Adapter \[14e4:43a0\] (rev 03)

04:00.0 Multimedia controller \[0480\]: Broadcom Inc. and subsidiaries 720p
FaceTime HD Camera \[14e4:1570\]

Following the suggestions in other posts here I did sudo apt install broadcom-sta-dkms and now sudo apt show broadcom-sta-dkms shows:

Package: broadcom-sta-dkms
Version: 6.30.223.271-29ubuntu1

Now, after rebooting, I found these lines in my dmesg:

wlan0: Broadcom BCM43a0 802.11 Hybrid Wireless Controller 6.30.223.271 (r587334)
wl 0000:03:00.0 wlp3s0: renamed from wlan0

And in lspci -k output I find this:

03:00.0 Network controller: Broadcom Inc. and subsidiaries BCM4360 802.11ac Dual Band Wireless Network Adapter (rev 03)
    Subsystem: Apple Inc. Device 0134
    Kernel driver in use: wl
    Kernel modules: bcma, wl

Now it works, so it's fixable, but it's way more difficult than it ought to be.

I used a tool that allows me to boot from the iso by making a specific partition. I installed the Ubuntu onto a 8gb USB drive(it is NOT a live installation, the USB drive is the os)

I just did a fresh install of Ubuntu Studio 26.04 LTS on my desktop system. Previously I’ve been running Ubuntu Studio 24.04 LTS. The driver for 24.04 is 580.126.09 and the 26.04 driver shows as 595.58.03. I have four displays arranged with three side by side horizontally and the fourth above them. The three are at resolutions of, from left to right, 1680x1050, 1920x1080, and 1680x1050. The one above them is 3840x2160.

The setup described above works well on the 24.04 system with all displays showing as running at 60hz. The 24.04 system runs on xorg and the 26.04 system runs on wayland.

The issues seem several. On the new system, the displayed rate is ~29.97 for all displays. Also, the 4k display does not display at all at 4k. If I set it to 1920x1080, though, it does display. Third, when I move the mouse between displays, there is a noticable hesitation in crossing between them. There are also occasional hesitations in movements within a single display’s display area. Lastly, at seemingly random times, the system will freeze with one or more displays turning to frozen video frazz.

The nouveau driver behaves similarly.

I have no idea how to proceed in solving these issues and would appreciate any input to that end.

Thanks,

BabaG

Short story long: Back well before the pandemic I made the mistake of buying the absolutely last plasma TV that was ever sold by my local BestBuy -- a Panasonic TC-P50x60 (50 inch). Because it had been discontinued and all the TV manufacturers were moving 100% to LED TVs I got a great deal on it, however...

What I didn't find out until much much later was that some dumbass firmware engineer @ Panasonic decided to save a few cents on EPROM by leaving out some of the normal menu options that were present in all other Panasonic TVs. In particular, this thing has an overscan of exactly 2.5% on all four edges, top, bottom, left, and right, and this cannot be turned off. (Trust me. I've investigated this eight ways to Sunday, called tech support, checked every menu option & combination of menu options. The overscan really and truly cannot be turned off on this model.)

Anyway, fortunately for me OpenELEC on my cheap low end x86 Home Theater PC... which I'm still running even though the OpenELEC project shut down several years ago now... allows the user to adjust the HDMI output to compensate for monitor overscan just like this. (I think that OpenELEC's successor, LibreELEC, supports overscan compensation too.)

Anyway here's the problem: For reasons of my own I want to now replace my HTPC with something a bit newer and I'd like to be able to access full-blown Linux (specifically Ubuntu) on that, with the display being my trusty old Panasonic TC-P50X60.

So, question: How can I do this?

Just dropping a fresh install of Ubuntu 24.04.4 onto my newer x86 HTCP and wiring it up (HDMI) to my TC-P50X60 produces unacceptable/unusable results because of the TV's overscan. I've tried several different things to try to get what's displayed to come out smaller, to compensate for the overscan, and so far nothing as worked. I already figured out that in order to have any hope I need to log in to Ubuntu using the X option, rather than the Wayland option, because then at least I can run xrandr (and/or xvidtune) but even after doing that, nothing I've tried is working. Xvidtune refused any attempt for me to change anything. Trying xrandr --scale (with different values) just produced error messages, and no other effect. I've also tried "xrandr --output HDMI-1 --set underscan on" which also just produced error messages (and no effect). Lastly, I tried: "xrandr --output HDMI-1 --transform 0.8,0,0,0,0.8,0,0,0,1". That "worked" but it only had the rather bizarre effect of making all of the displayed icons & fonts bigger, but not actually changing the total size of the entire desktop at all.

Any help or guidance appreciated.

Note: I'm an experienced UNIX/Linux user, but I know next to nothing about graphics, displays, windowing systems, desktop environments, compositors, etc., etc., so please be gentle with me. Thanks.

So firstly I want to say I’m a complete newbie with Ubuntu. I have used it on a spare laptop for a few years but I don’t have much understanding, if I have any problems I come straight here.

So I needed to transfer files to an external drive to move to my main pc. I for some reason cut and paste and didn’t copy them and during the transfer the external drive must of disconnected and I lost all of my files from Ubuntu laptop and they also didn’t transfer to the external drive.

I used test disk to try and recover any lost files and everything seemed like it worked but then upon rebooting the laptop I am now stuck at “Minimal BASH-like line editing is supported” I have tried using a usb version of Ubuntu to try and fix the boot (which has worked for me in the past) but this time when trying to install the boot-repair i just get the message “unable to locate package boot-repair”

How badly have I messed up or is this fixable?

I also didn’t continue the transfer of files after the original transfer fail so now I can’t access the remainder of what I still had on the laptop

The hardware requirements for Ubuntu 24.04.x are: 2GHz processor & at least 4GB of ram.

Has anyone ever actually tried to run 24.04.x on a system with only 4GB ram? I have to ask because I've been trying it, repeatedly, and every time the system gets to the point where it has to start swapping (as shown by top) SOMETHING crashes... either Firefox or gnome-shell or the kernel. (That last one is just a guess, but when the whole system locks up with a totally black screen I gotta think that's a kernel panic.) In one case where my keyboard & mouse clicks (but not mouse movements) suddenly stopped working, after a reboot I got some message asking me if I wanted to report an error to Ubuntu central and when I looked at the details it said that gnome-shell had gotten a SIGBUS! Yikes! THAT should never happen!!

So anyway I was able to repeat these failures, consistently, on 2 different, mostly identical systems, specifically my two HP T620 thin clients, each with a AMD "Kabini" GX-415GA (quad core), each having only 4GB ram installed and each with a Sandisk X600 128GB M.2 (SATA) "hard drive" installed. (The only differences between the two is that one has a WiFi card installed & the other doesn't and one has been updated to the latest HP T620 BIOS and the other hasn't yet... but the BIOS rev. apparently makes no difference to these mysterious crashes. I know. I checked.)

I have already ordered more memory for these machines, and yes, clock speed for these CPUs is only 1.5GHz, which doesn't meet the strict letter of the 24.x.x hardware requirements, but setting that aside, even if I put 8GB in each of these machines, if my guess is correct that there is a serious memory management bug underneath all these repeated crashes then what happens when and if I max out the 8GB and start swapping? Obviously the mysterious application, gnome-shell and (possibly) kernel crashes will reappear. So just adding more memory is obviously NOT a proper solution.

I'd like to hear whatever anybody might have to say about all this. Opinions welcome. Should I just give it up and accept that modern Ubuntu is just never going to work on 12.5 year old hardware? Should I file a formal bug report? If I do, will anybody even care to investigate, given that this hardware almost qualifies as "antique"?

As I say, I own two of these systems. They are slow enough to be perfectly useless as Windoze machines, and if I can't run Ubuntu on them then at best I could only maybe run LibreELEC on them (but maybe that would crash too). As they sit now they're really just expensive paper weights.

If anyone was at all interested in investigating these problems then I would be more than happy to loan one of these systems to that person for, say, 30 days, and I'd pay for shipping both ways (continental US only).

These were pretty cool machines in their time, and for most stuff, performance-wise, they still beat the pants off a Raspberry PI 4, and with a case & power supply they can be had used, off eBay, for less than half the cost of a PI4 + case + power supply. So I think that it's a damn shame that the most popular Linux distro won't support them in their standard (4GB) configuration. (There are, I'm sure, several hundred thousand of these exact machines out there in circulation. They were real popular for offices, back in the day, in part because they're fanless, passively cooled, and thus, dead silent.)

I installed Octave, and the Bengali fonts in many websites such as Wikipedia (all articles) are rendering quite badly afterwards in both Firefox and Chromium.

Example: The font is very small, and it looks somewhat broken in this Wikipedia article:

How to fix this issue?

I have all these checked:

Secure Boot → Enabled

Secure Boot Mode → Standard

on my ver 2.22.1289 2025 american megatrends BIOS

mokutil --sb-state also shows SecureBoot enabled in the liveUSB's terminal

Yet it still gives me this:

INVALID_SECURE_BOOT_MODE error with secure boot policy (PCR7) measurements: deployed mode should be enabled in order to generate secure boot profiles

I also tried to restore to factory reset multiple times, but that didn't help.

Anyone have met the same situation as me?

I have a HP Pavilion Notebook. I recently installed Ubuntu 24.04.4 on it. When I suspend the machine, the Airplane mode automatically turns on and cannot be turned off. I have tried toggling it in the settings but that doesn't work. Need help

sudo lshw -C network returns *-network description: Wireless interface product: RTL8723BE PCIe Wireless Network Adapter vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:08:00.0 logical name: wlo1 version: 00 serial: d8:5d:e2:63:02:23 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=rtl8723be driverversion=6.17.0-22-generic firmware=N/A ip=192.168.1.21 latency=0 link=yes multicast=yes wireless=IEEE 802.11 resources: irq:18 ioport:5000(size=256) memory:c6100000-c6103fff

I'm using cage (the single app opener on the cli that runs individual apps without a desktop environment,) to run apps on wayland in an effort to remove all distraction. Can't have 50 different windows open and all that temptation if you only have one app to work with!

I start the apps like this:

cage thunderbird.

It works! but the windows (the window X, minimize and maximize buttons, and all the content inside the window) of the apps I run all look zoomed out and shrunken. Even if I zoom in to the content, the buttons on the top of the window "menu bar" part and the minimize maximize and exit buttons, all remain shrunken.

I want the window edges, window buttons, and everything in the window to not look miniature. How do I expand it all? All of it.

I am attempting to try out the new 26.04 version of Ubuntu Unity. I have downloaded the ISO ubuntu-unity-26.04-desktop-amd64.iso and put it on a Ventoy stick and am able to boot OK, to the point where it brings up a login prompt with a dropdown at the top that only shows 'Other' and a username and password field. I thought that user ubuntu with empty pwd should work but it says it is invalid. I have tried unity, ubuntu-unity and other combinations but nothing seems to work.

What am I doing wrong please?

I'm from India, currently running Ubuntu 24.04.4 LTS. I am excited to upgrade to the newly released 26.04 LTS. However, even today's morning (Apr 25), my software updater couldn't find a newer version to upgrade to. Articles like (https://linuxconfig.org/upgrade-ubuntu-24-04-to-26-04) and (https://linuxize.com/post/how-to-upgrade-to-ubuntu-26-04/) suggest a manual upgrade via the terminal, first upgrading to a non-LTS version (25.10). I am not willing to wait till 26.04.1 LTS release.

How do I upgrade? Please help!

Just did a fresh install of Ubuntu 24.04.4 LTS and there is no HDMI sound out device listed to select for sound. Only "Digital output (S/PDIF) - USB Audio and HID" and "Analog Output - USB Audio and HID".

Did a bunch of digging, and tried any potential solution I could locate from updating intel drivers, to installing/using pulseaudio, and any other troubleshooting steps I could find. Even swapped out HDMI cable for a new one.

Also, for whatever reason, I can't get a command line listing of devices.

Still not seeing HDMI as a sound output option and sound out remains elusive.

At wits end.

Note that the HDMI audio works just fine for other devices connected to the monitor. HDMI audio worked also from the system under Windows 11.

I'm trying to update fw on a Dell Latitude 5500. fwupdmgr is checking for a shim in the EFI/debian folder.

What's up with that?

Obviously it's failing because I'm running Ubuntu 24.04.4.

Please accept my apologies for not immediately providing log files. If needed, please tell me what information will help.

Edit 1: exact command & output:

Secure boot is enabled, but shim isn't installed to EFI/debian/shimx64.efi

I'm relatively new to Linux and I've been encountering quite a few issues while trying to navigate Ubuntu on my system. Despite having everything updated and upgraded, I'm still experiencing frequent freezing, boot errors, and crashes, especially when using Firefox, Chrome, or other applications. It's been quite challenging for me.

Here's some information about my system:

  Notebook: Asus Vivobook 15 M1502IA
  Processor: AMD Ryzen 5 4600H with Radeon Graphics (3000 MHz)
  RAM: 8GB
  Storage: 256GB SSD
  Kernel: 5.0.28-generic
  Ubuntu version: 23.10.1

Additionally, I should mention that this notebook fails to boot Windows; it consistently encounters BSOD during installation. I've tried Windows 11, Windows 10, Fedora, and now Ubuntu, but none seem to work smoothly. I'm starting to suspect a hardware issue, as I've had this machine for two months now and haven't been able to use it properly.

The latest error I encountered was a kernel panic with the message "not syncing fatal exception in interrupt" while attempting to boot. This happens around 10 times a day.

After some troubleshooting, I managed to get the notebook to function with the following commands added to grub:

amdgpu.gpu_recovery=1 intel_idle.max_cstate=1 processor.max_cstate=1 

rcu_nocbs=0-11

However I'm still experiencing freezing, particularly when using WhatsApp Web or when the notebook is plugged in (which it struggles to boot from). I also encountered freezing when attempting to install a game on Steam, which led me to abandon the endeavor. Despite these challenges, I was able to use the computer for over an hour today, even watching an episode of a series on Netflix and a football game via streaming.

At this point, I'm considering reaching out to ASUS official support. My suspicion is a significant hardware bug, especially given the difficulties I'm having with booting while plugged in. I'm at a loss on how to proceed and feeling quite exhausted from all the troubleshooting.

When I installed Ubuntu a year ago, I created a partition (alas) on which I kept Windows, just in case. I've been booting in Windows extremely rarely because I work from Ubuntu only. Two days ago (alas again) I booted in Windows and naturally a ton of updates were waiting for me. So I did the updates choosing "Update and shut down". After that shutdown, however, both Windows and Ubuntu are failing to boot. Windows freezes in "Preparing Automatic Repair" and Ubuntu mostly just gives a black screen (sometimes it says "TPM interrupt not working, polling instead) although I did reach the purple screen twice, managed to enter my password but then it froze.

In UEFI, the computer (HP Zbook mobile workstation, i7) passes the system fast test, on the extensive test it passes the short DST check but freezes on the optimized DST check.

A boot through advanced Ubuntu options/recovery mode also doesn't work (it runs for a while giving error messages like kernel panic, etc. and then freezes).

I've created a live USB stick (which works, I've just used it to install Ubuntu on another computer) but also that won't boot, not even in the safe graphics mode, it starts booting and then freezes. (I've disabled Fast Boot in UEFI).

Is there any way this can be solved? I haven't done a back-up in a week and if nothing else I'd like to recover some of the data from that disk.

Please help me ... I'm not a very experimented user ...have some notions but my logic is not working :(

The story is the following

• more then 10 years ago (maybe in 2010) decided to use a PC in our LAN (about 10 PCs) to store the common documents, invoices, datasheets and stuff like this in a centralized location so we choosed to use Linux (Debian Lenny) for our SHAREPOINT, after a few days we've started to use a CRM based on PHP4 and SQL database
• everything worked fine without any intervention only a few small maintenace ... until a month ago
• The main problem was that the PC stops to boot and display the following message Kernel panic - not syncing : attempted to kill int ! exit code=0x00007f00 This error appear even if I'm trying to boot from a bootable USB I've tried using BootRepair the report uploaded https://paste.ubuntu.com/p/7f8VZCjHW6/ after the reboot https://paste.ubuntu.com/p/kP7by6mB9d/

I've decided to install UBUNTU ... the latest version and Apache 2, PHP 7.4, SQL

so the problems:

• crontab is not working neiher the global or the user's or the root's
• the CRM based on PHP/SQL is working about 20xtimes slower
• updated the PHP to 8.0 an the php -v display "PHP 8.0.3 (cli) (built: Mar 5 2021 07:54:13)" but phpinfo() displays "PHP Version 7.4.16"

Specs:

• Processor: Intel Celeron CPU 2.80GHz
• Memory: 967MB (575MB used)
• Machine type Desktop
• OS: Ubuntu 20.04.2

What are the best practices to configure BIOS/Firmware settings for dual boot Ubuntu install alongside Windows 10?

I've turned off the "Fast Initialization" option on my computer, just because I've tried two other times a year ago and I failed. In that times, I've followed the tutorial the right way (I think).

When it failed the last time, it was when GRUB lead only to Ubuntu. If I selected the Windows option, GRUB returned again, leading me to an infinite loop between Windows and GRUB, however my files weren't lost.

I'm installing Ubuntu 18.04 because the 19 version gave me a kernel panic.

Detailing my BIOS and Board (information from CPU-Z):

• UEFI: Yes

• vendor: ASRock

• model: H61M-HVS

• Complete System details: https://pastebin.com/izzX7Gv4

In conversation by chat, I've put the 18.04 iso and the problem is the same. When I put the ISO and change the boot order by ASRock BIOS GUI, booting by USB Flash Drive (not UEFI, there is an option for this too), it loads the screen with an icon of accessibility and another one for a keyboard, then there is a black screen outputting an error message.

I've tried to put the same USB Flash Drive in another computer, but another error is given to me: Tested with 18.04 Ubuntu ISO

I'm now closing this question only related to dual boot tips. In relation to the problem in BIOS, I'll create another post.

So today I plugged in my 31 GB USB flash drive and opened it up. I was in the process of creating a Windows bootable device, when I tried to copy the files from my computer to the USB. I got an error message telling me I do not have permissions to add files.

• I added and removed partitions on the usb thousands of times
• I formatted it a bazillion times

And it seems I am unable to do the simple task of copying and pasting files.

I have passwords for the systems. I own the computer.

Why can't I copy files?

Formated it to ext2, fat32 and nfts: no results, same nonsense

I'm new to Ubuntu. Installed ubuntu by formatting my existing C Drive in Windows 10 OS. So I have only Ubuntu in my laptop. My D drive is left untouched which is a NTFS file system. Please guide me how to mount this so that I can work with my files.

I just installed Xubuntu alongside an Arch-based distro. The problem is that Grub2 does not detect the (btrfs) partition of the previous distro, so I can't boot from it. I have already tried update-grub2.

By the way, that btrfs partition used to boot alright from Grub2, before I installed Xubuntu.

What can I do?

A certain cellphone maker has changed the default format of taking pictures to HEIF (.HEIC, High Efficiency Image File Format), without asking the users (although there is still the option to use jpeg/jpg).

Is there an app/program on Ubuntu that can open and/or convert HEIF-pictures and even let them be edited?

I emptied the Shotwell bin, and accidentally chose the "Remove from Library" option, rather than the "Remove and Trash" option. How can I now delete the files permanently from disc that are no longer in the library? (There were 91 files in the bin.) I'm using Shotwell v0.22.0.

I have installed ubuntu 16.04 and my GPU is R9 380X. The Driver used is AMDGPU..is there any way to control the fan of my gpu? because it never spins.

Thanks !

I am using Ubuntu 14.04 on a Dell i3 4005 and I am unable to boot my laptop from yesterday.

It directed to GNU grub version 2.02~beta2-9ubuntu1.3 window, and I have to select one from followings

1. Ubuntu
2. Advanced options for Ubuntu
3. memory test (memtest86+)
4. memory test (memtest86+, serial console 115200)

When I select option 1 above, it goes to a purple colored screen displaying ubuntu in the middle, and nothing happens thereafter.

When I select option 2 above, I get the following list.

   Ubuntu, with Linux 3.16.0-50-generic
   Ubuntu, with Linux 3.16.0-50-generic (recovery mode)
   Ubuntu, with Linux 3.16.0-49-generic
   Ubuntu, with Linux 3.16.0-49-generic (recovery mode)
   Ubuntu, with Linux 3.16.0-43-generic
   Ubuntu, with Linux 3.16.0-43-generic (recovery mode)
   Ubuntu, with Linux 3.16.0-41-generic
   Ubuntu, with Linux 3.16.0-41-generic (recovery mode)
   Ubuntu, with Linux 3.16.0-37-generic
   Ubuntu, with Linux 3.16.0-37-generic (recovery mode)
   Ubuntu, with Linux 3.16.0-33-generic
   Ubuntu, with Linux 3.16.0-33-generic (recovery mode)
   Ubuntu, with Linux 3.16.0-31-generic
   Ubuntu, with Linux 3.16.0-31-generic (recovery mode)

If I select any of above it will display so many text and end up with following error message.

Kernel Panic - Not syncing: Attempted to kill init! exitcode=0x00007f00

Then I tried to make bootable USB with Ubuntu 15.10, and when I try to install it it ask me to backup Dell software and there are 3 buttons on it Quit, back and Next, but only the quit button is accessible and it quits the installation.

I have a Lexar 16GB USB stick and for some reason it won't mount. Ubuntu won't even recognize it.

Info about it... nothing much. I used it once as a Backtrack live USB and tried to use it once as an Ubuntu Studio 12.10 live USB (ended up with a kernel panic). So now I am trying to just reformat it (the easiest/fastest way to wipe everything off) and just use it as a regular USB drive or maybe use it as a Backtrack live USB again.

Is there any way I can force Ubuntu to recognize it? I know the port works as my USB mouse receiver works fine.

I'm running Ubuntu 12.04 LTS (old hardware, I'll upgrade it soon) on a Toshiba Satellite A105.

By using this guide I was able to force-mount it, but it still doesn't show up in Places (PCManFM because I use LXDE) like it usually does. Another strange thing, neither does the Windows NTFS partition I set to automount.

It appears that my system has stopped auto-mounting things. The devices show up in their respective /media/deviceHere/ folders, but not under Places in PCManFM.

Weirdness.

Whatever it was, I just had to delete/unmount anything with the name Lexar or External USB in the media folder and it is now recognized!

Never mind, now it has disappeared again. If I want to access the /media/Lexar folder I have to be root and the Windows partition still doesn't show up.
