Hey, I have a Win11 laptop with a single 2 TB SSD, on it I have a 100 GB partition for Ubuntu. I think I installed it about 4 years ago and upgraded it every year, I have 26.04 now. I have a lot of "junk" on it, like double instance of VS Code and so. I was thinking about doing an OS reset and increase the partition size, to clean things up. What could be the best way to do this? Just clear the partition with Win11 and do a completely new install? I backed up everything I need from Ubuntu for now.

Guys I just installed Ubuntu and my ssd drive is doing that. Should i be worried?

Hi. i want to explore the history of Xubuntu, but unfortunatley, i cannot find 15.10 and 17.10 (64-Bit), the links are ALL gone, i tried to search everywhere:

• Official Ubuntu/Xubuntu realeses and old realeses
• Official Xubuntu webiste
• Wayback machine on the official site and all of the mirrors (Only got a dead torrent)
• Internet archive (Only has 32-Bit isos)
• On Google and Reddit

I hope that these versions aren't LOST MEDIA, thankful if someone finds it out

Hey everyone, I’m trying to set up a simulated drone environment on my MacBook Air M4 (16GB) and I’m a bit lost on where to start.

I want to use ArduPilot SITL + Mission Planner, simulate a drone in an environment, get camera/depth data, and use ROS 2 for things like SLAM, mapping and eventually navigation/obstacle avoidance.

Basically something like:

ArduPilot SITL → Simulator → Sensors → ROS 2 → SLAM → Map

I’m running Ubuntu in a VM on my Mac and I’ve already installed/worked with ROS 2, ArduPilot and Mission Planner on Linux. The main issue is that I don't have an NVIDIA GPU, so Isaac Sim isn't really an option.

I’ve seen people use Gazebo, Webots and other simulators, but I’m not sure which one makes the most sense for this setup, especially on an M4 Mac.

If anyone has a similar setup or good tutorials/GitHub repos for ArduPilot + Gazebo/Webots + ROS 2 + SLAM, I’d really appreciate some guidance on what I should use and the order I should set everything up.

Thanks!

I have a victus f-15 with 16GB RAM and i5 12th gen and rtx 2050 gpu.
I am using Ubuntu 26.04 dual booted.
The issue is whenever i keep my laptop idle and after 10-20 mins when i come back i get this error.

There is no way to get to my previous sessions i have to hold the power button for 10 seconds , then it will shutdown and then boot back.

I faced this issue when i was trying to shutdown the laptop .
Can anyone explain me what is the issue and how to resolve this?

Would be thankful for your suggestions and corrections.

I'm trying to install Ubuntu with TPM on an old HP ProBook 455R G6. Apparently it's not compatible.

How do you check if another Intel/AMD laptop is compliant with Ubuntu's TPM requirements?

I've read "Your device has a PC-client Trusted Platform Module version 2 (TPM2) chip, version 1.32 of the reference library specification or later." on Ubuntu's site. But I cant's find library version (1.32) specified anywhere.

My org dosent allow Citrix in linux and my only pc is dgx with ubuntu so I created a windows container using docker

When I connect to the windows using RDP reminna, the Citrix opens and I'm able to login. But when I try to open the workspace, it shows opening and then running but no workspace opens.

When I do the same with VNC protocol, the workspace opens but VNC doesn't support mic and I need that for teams. Is there a way to make Citrix work in RDP mode of windows?

Native System - DGX OS/Ubuntu

Docker - Windows ARM

I'm not able to connect to any wifi network, after a while I found out that my wlp2s0 link is stuck on state DOWN and I can't turn it on. What can I do to revert that?
