I'm new using Linux and I'm having trouble approaching an issue.

I installed DaVinci Resolve 20 on my computer. It starts fines, opens up my project but as soon as I press CTRL key it crashes. I will be running fine, I can use some features, but pressing CTRL key in the Fusion tab just crashes it instantly.

I'm very intrigued by this and I need help to solve this issue. I have an ongoing project that needs me to use DaVinci so I'm a bit in a hurry.

Here are some information that may be relevant:

I have a Nvidia graphics card RTX 3060, 16Gb RAM running Ubuntu 24.04.3 LTS. Intel® Core™ i7-9700KF × 8. I'm trying to Install DaVinci Resolve 20 free version (I tried the latest 20.3 version and it has the same problem)

I assume the crash is not being caused by hardware limitation, I have the newest driver for the graphics card installed (nvidia-driver-580-open) and DaVinci shows me my graphics card in it's configuration settings, so that shouldn't be the cause of the problem, right?

Let me know if you know a way to solve that or at least discover whats the issue. Thank you in advance.

I made a dual boot, installed ubuntu on a partition of my disk.
But when i run my computer, it starts on windows without asking if I want to go on Ubuntu or Windows. Please help, it has been a week and still can't make it work...
I was told it is a grub problem but can't solve it.

I'm new to Ubuntu and it's been 3 days since I've been using it, I'm comfortable with 24.04 LTS, but I'm curious and want to try the Non-LTS (25.10). Is it possible to do it?

Yesterday I have installed a new GPU the Radeon RX 9070XT Tiachi and my system won't recognize the card.

Steps I have taken:

Motherboard MSI PRO B850-P wifi, updated BIOS:

latest version: AMI BIOS 7E56v2A75 2025-09-10

Updated my kernel from 6.17 to 6.18.0-061800-generic (Ubuntu 25.10)

also updated to Mesa 25.3.1

Uninstalled the AMD GPU stack and reinstalled the latest version:

dpkg -l | grep amdgpu

ii amdgpu-install 30.20.1.0.30200100-2255209.24.04 all AMDGPU driver repository and installer

ii libdrm-amdgpu1:amd64 2.4.125-1ubuntu0.1 amd64 Userspace interface to amdgpu-specific kernel DRM services -- runtime

ii libdrm-amdgpu1:i386 2.4.125-1ubuntu0.1 i386 Userspace interface to amdgpu-specific kernel DRM services -- runtime

Currently I have my HDMI plugged into the motherboard (R7 7700 cpu) so that I can see, because when I connect the DP to the GPU my screen stays black.

Here is some extra info from glxinfo:

I am curious about this bit, 512MB is from the integrated graphics, but the 16GB should be my new card?

I've been scouring the internet for a couple of hours trying to find a solution, but so far anything I've tried hasn't worked.

I hope someone can help me out with figuring this out, thanks in advance.

I am new to Ubuntu. I am currently using version 24.04 and wanted to know if the gestures of the Apple Magic Mouse 1 work natively or if I need to download something (assuming it is possible to use them).

I am connecting via XRDP to a Ubuntu Server. When i try to establish a VPN Connection via Surfshark I have to enter my Password 4 Times.

What I have researched was to apply some policies to prevent that but it is not working.

The following Policies were created:
/etc/polkit-1/localauthority/50-local.d/universal.pkla

[Allow access to anything for remote users]
Identity=unix-user:*
Action=*
ResultAny=yes
ResultInactive=yes

ResultInactive=yes

Another User in Linux Mint Forum stated the same that these policies don't work anymore:

Anygone got a Tip?

Now that Ubuntu 24.04 is released and I upgraded my laptop, and the next LTS is scheduled in about 4 months, nautilus-gtkhash is no more in official repositories. How do I right-click in nautilus to get hashes of various files?

How do I stop the auto change of screen brightness on the Asus vivobook? I have tried the display which I disabled the change brightness according to context as well as disabled the brightness of display when power saver is on. But it still occasionally changes brightness when I typed some certain combination of keys on the board. Will welcome any advice. It is very frustrating.

Bonjour,

Je sollicite votre aide concernant un problème survenu après une tentative de mise à niveau de mon système Ubuntu 22.04 LTS vers Ubuntu 24.04 LTS.

Pendant la mise à niveau, une coupure d’électricité a interrompu le processus, et depuis, mon ordinateur ne démarre plus correctement. À l’allumage, l’écran affiche un message d’erreur similaire à :

```

ALERT! UUID=xxxxxxx does not exist. Dropping to a shell!

(initramfs)

```

J’ai tenté certaines commandes comme `ls /dev/sd*` ou `fsck`, mais sans succès. J’aimerais savoir s’il est possible de récupérer mes données ou de réparer le système sans tout réinstaller.

Ma machine est un Lenovo T410.

Merci d’avance pour votre aide précieuse.

Cordialement,

Ezéchiel

G'day All,

I decided to ditch Windows as I'm now retired and no need to be part of Windows Enterprise BS.

I have a Lenovo Legion Pro 7 which I'm running Kubuntu 25.10 with an i9 processor and a NVIDIA RTX 4070 graphics card.

Everything has been working really well except that I have an issue with sound.

After a reboot, I can play a Youtube video on a Chrome browser and the sound works. If I start playing sound in another window or in Firefox there is no sound. If I go back to the original window, I lose the sound there as well.

I think this is an issue with Ubuntu 24.04+ as I tried Pop_OS 24.04 beta and had the same issue. If I use Pop_OS 22.04 I could not reproduce the issue.

Here is the sequence of events.

Immediately after reboot

Any ideas on how I can fix this?

I haven't found anyone with a similar issue.

I could go to Kubuntu 22.04, as I think that works but I don't want to be stuck in the past.

Thanks in advance, Chris

I just installed Express PCB with Wine, but at the first launch screen all of the text is missing:

I attempted the steps here:

But the issue persisted.

This is:

wine --version
wine-10.0 (Ubuntu 10.0~repack-6ubuntu1)

And Ubuntu 25.10 ; I have a message that there are some updates available for Ubuntu, and I am moving forward with those. But is there something else missing here in terms of a fix of this issue?

Thank you in advance for your help or suggestions in the comments section.

Update: I installed all the Ubuntu updates, and the problem persists. I am stuck on the next troubleshooting steps needed. It is probably more of an annoyance this problem, but I am interested what the text actually says, so additional troubleshooting steps would definitely be appreciated.

In October, I migrated from Win 10 to Ubuntu, rather than suffer Win 11. It has been going well, but I am getting this problem when Ubuntu Discover tries to do a "firmware update":

Ubuntu Discover update "failed to write-firmware: failed to write (null): failed to write data to efivarsfs: Error writing to file descriptor: Invalid argument"

Even more irritating, I dismiss the error message and it pops right back. The Discover updater captures the cursor too quickly to close the program, leaving me stuck. The cursor/mouse is captured by Discover, leaving me unable to do anything other than close the error message box, which pops right back endlessly.

The first time this happened, I tried the reset button on the PC, but that had the bad side effect of leaving a couple drives with "missing mount points", which I had to remove from the PC and put in my old Win 10 pc and run partition manager to scan them for errors, then back in to my main PC and all was happy again. Yes, I know there is a way to do this in Ubuntu, but I felt too newbie to try it and risk losing important data. And yes, I do have a back up, but some recent things might have been lost.

The second time this happened, just this morning, I was able to click on the Discover icon on the left of the Task Manager bar and manage to quit Discover after several tries. A quick right click on the icon and then a typed Q to quit, if done quickly enough was able to do the job.

Thank you for any help

First, Opera-developer stopped working, and a few days/update later Opera-beta. Both on Ubuntu 24.04 LTS and 25.10. On 24.04 I got it working by starting an X11 session.

Both fail on Wayland with this error message:

Is there any testing being done at Opera at all?

I thought snaps were going to fix problems, but it seems to me they're causing just more and more (rather silly) issues.

Does anyone know a fix?

I am used to access to my pinned applications with the windows + [0-9] shortcut on Ubuntu 22.04.5.

I recently upgraded my laptop to Ubuntu 24.04.2 LTS and this shortcut only works for non special characters. I am using an AZERTY keyboard and so far, I found that the keys é,è,ç,à (mapped to the keys 2,7,9,0) don't apply the shortcut.

I tried to hold the shift key while applying the shortcut but it only opens a new instance of the selected application instead of navigating to the existing one.

Of course I could use my mouse or the alt + tab shortcut to navigate through my applications, but I find it more precise when I have a bunch of windows opened. Did this behavior happen to anyone?

After I installed Ubuntu 20.04.4 LTS in my PC, it shows --

Installing, this may take a few minutes...
WslRegisterDistribution failed with error: 0x80070422
Error: 0x80070422 The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.

I'm not sure what I should do as pressing any key does nothing but closes the terminal. P.S: I'm using Windows10

First ran into this problem after upgrading from Ubuntu 18.04 to 20.04 in an old HP Pavillion laptop (dv7-2185dx): the system was stuck at a blank screen sometimes after a boot/reboot. After editing grub to enable debug mode (linux /boot/vmlinuz-5.4.0.58-generic root=... ro debug), I see that whenever the boot sequence hangs, it is always after "random: fast init done" or random: crng init done (or both). Sample output below:

snapshot: boot halts after crng init done

I have checked previous questions on similar issues, e.g.: Ubuntu installation stuck at random crng init done Boot - very slow start "random: fast init done"

However, the solutions there don't work in my case: I have no SD cards to remove, I boot from an internal SSD and my UUIDs in blkid and fstab agree, my system does not use a swap partition but rather a swap file in the same partition as the system, I tried installing rng-tools and haveged but the situation was not resolved. I also did a fresh 20.04 installation and this problem occurred there too.

Curiously, I have Ubuntu 18.04 in another partition of the same disk which always boots fine. Both systems seem to use the same initrd image version (initrd.img-5.4.0-58-generic).

I am baffled at this point, hence the request for help. The problem is not even well-reproducible, it happens randomly but quite frequently. Any ideas what might be going on, or at least any pointers on how to troubleshoot?

Happy to provide more info as necessary...

I recently noticed that my Dell laptop is overheating because the fan stops. I've read almost all posts on the internet related to fan control, anything related to i8kctl and lm-sensors.

The laptop runs dual boot and there's no issues when I'm running Windows 10, it only happens on Ubuntu 20.04.1.

What I've found out is when I run command sudo pwmconfig, I'm getting this output:

Found the following PWM controls:
hwmon5/pwm1           current value: 0

Giving the fans some time to reach full speed...
Found the following fan sensors:
hwmon5/fan1_input     current speed: 0 ... skipping!


There are no working fan sensors, all readings are 0.
Make sure you have a 3-wire fan connected.
You may also need to increase the fan divisors.
See doc/fan-divisors for more information.

It suggests that my fan sensor is having some kind of connectivity problem. However the fan turns on sometimes for few seconds, then dies again. At the same time, it runs just fine on Windows, so imo this is not the problem. I've updated BIOS, cleaned and tested the fan so my guess it's a Linux problem.

I tried to manually control the fan with i8kctl, but it didn't work for me either. Can anybody help me deal with it?

I upgraded from 18.04 LTS to 20.04.LTS and the system ran fine until a new kernel update showed. Now it hangs on creating the initrd image.

Has anyone else seen this kind of bug?

I wanted to know for how much time the screen of my laptop(with Ubuntu) was 'ON' for the whole day.

I have used 'uptime -p' but it doesn't work if you turned your system off and then later turned ON for use. Hence, it tells for how long the system(not screen) is running from the last time it was turned ON.

Please suggest if there are any other softwares/desktop-apps also.

When I add an IP to interface,the kernel will add a direct route to main table,and if I delete the IP,the kernel will delete the direct route from main table.As follows:

root@template:~# ip addr add 192.168.10.1/24 dev eth2 
root@template:~# ip route show table main | grep 192.168.10
192.168.10.0/24 dev eth2 proto kernel scope link src 192.168.10.1 
root@template:~# ip addr del 192.168.10.1/24 dev eth2
root@template:~# ip route show table main | grep 192.168.10     
root@template:~# 

If add another route table to /etc/iproute2/rt_tables,how to make the new table works like main table add/del direct route automatically?

Thanks!

I have installed "uwsgi" using pip method. But when I run uwsgi, I'm getting "Command 'uwsgi' not found, but can be installed with" error. If I again try to install using pip, I'm getting

Collecting uwsgi

Successfully installed uwsgi-2.0.18

which means it's already been installed.

What else am I missing out here. Thank you.

Background

Instructions indicate installing numpy in a python virtual environment (log below). The log indicates warning and errors: although the install process indicates 'Success', the warnings / errors indicate uncertainty. That being said:

Questions

1. What are the problems associated with said errors & warnings?
2. Is there a test that can confirm there will be no problems?
3. How can the install command be improved so as to avoid the same errors / warnings?

I am a long time Mac user, and totally new to Ubuntu 18.04 .

Pls help thanks.

I installed 17.10 recently and went to change the graphics from the Nvidia card to the Intel card to save battery. After switching the Prime setting to use the Intel card, I can no longer open X server settings. I've uninstalled and reinstalled the program, but still nothing happens when I go to open it. Is this just an issue with 17.10 that will be fixed in later releases, like the upcoming 18.04?

I just started using Ubuntu on a Parallel desktop off Mac OSx. I am hoping to use this platform to operate my astronomy hardware from my Mac instead of Windows.

The first issue I am encountering is that I am being told my Login Keyring Password "no longer matches" my login. I am confused - I provided a password as I was setting this up, and so I don't know what this is about and how I can fix it. Thanks for the help.

I'm trying to print from tray 2 but I can only print from tray 1 and there is no way to enable more paper sources in cups is there a way to enable this option?

My printer is a Epson xp950.

I tried setting up ufw on my remote Ubuntu 14.04 server so i installed it and allowed ssh with the command

sudo ufw allow ssh

after that I tried to enable ufw but I get the following error:

ERROR: problem running ufw-init
iptables-restore: line 77 failed
iptables-restore: line 30 failed

Problem running '/etc/ufw/before.rules'
Problem running '/etc/ufw/after.rules'

Then I found this troubleshooting guid which recommends to comment some lines in the mentioned .rules files, but I would have to comment every line in all the files to get it starting. I can't do that since I need at least the allow ssh rule.

The most suspicious line is the one mentioning a iptables-restore error:

Does anyone have had similar issues and solved it or has any idea how to solve the problem(s)?

Thanks in advance.

When I try to open any OS on Oracle VirtualBox an error accurate.

Failed to open a session for the virtual machine xp efendi.
AMD-V is being used by another hypervisor. (VERR_SVM_IN_USE).
VirtualBox can't enable the AMD-V extension. Please disable the KVM kernel extension, recompile your kernel and reboot (VERR_SVM_IN_USE).

How can I repair this problem?

The backspace is unable to erase the characters. The navigation keys produce alphabets.

Can anyone tell me how to fix this?
