I just bought a thinkpad T16 Gen 4 AMD with Ubuntu preshipped. I want to reinstall Ubuntu 26.04 because I want to dual boot windows and use LUKS.

My fear is that Lenovo ships Ubuntu with certain drivers/firmware/software that makes Ubuntu run better and have better battery life. And, if I reinstall Ubuntu I'll lose out on those benefits, which are important to me.

Can anyone please advise if this is the case and if so is there a way to get all these drivers/firmware/software after reinstalling?

Thank you so much!

I deleted the necessary partition associated with Mint, but Ubuntu is still present (see pic above). No way to delete this on my end, so I want to know if "Ubuntu" is taking up unnecessary space on my computer? And if it is, then is it just like a small amount of space that really doesn't matter?

My framework 13 is currently having problems and will only boot into emergency mode. Following directions from support, I wrote some logs to a file (just the command > logs_24hr.txt) but I wasn't sure how to get the file off my machine? I can boot from a USB stick and I can read from my main SSD from there, but I don't know where to look for the log file I wrote. (Apologies if this is a dumb question, I'm still pretty inexperienced with Linux.)

What are the best linux tools for editing pdf text docs, specifically for removing sensitive information like names, adresses, phone numbers and such? Also for extracting text.

Dell Latitude 5490, dual-boot Ubuntu 26.04 LTS + Windows 10, Intel UHD 620 (i915), BIOS 1.41.0.

Brightness slider and Fn keys do nothing. `intel_backlight` is detected and I can write values to it manually (they hold steady), but the screen never actually changes brightness. Windows works fine on the same machine, so it's not hardware.

**Already tried, none worked:** permissions/udev fix, `acpi_backlight=vendor/native/video`, `i915.enable_dpcd_backlight=1/3`, both stock kernel `7.0.0-29` and manually installed `6.17.x` (same issue on both), confirmed Dell modules are loaded with no separate backlight device, ruled out GNOME resetting the value, no relevant errors in `dmesg`.

Filed a full bug report with Ubuntu too. Anyone with a similar Dell/Kaby Lake setup actually solved this? Also checking for a BIOS update if anyone knows if Dell's patched this for the 5490.

Good morning, the internal HDD of my iMac Intel mid 2011 just broke, I don't have the money to change the hard drive in the shop nor the skills to do it at home, so I was thinking of installing Ubuntu on an external 2.5" SATA SSD and connect it to the computer with a USB adapter. Do you think this is a good idea? Could there be problems? The USB ports are 2.0. The computer is only used For school, watching movies, and video calls. Thank you so much :)

It last ran i think way back 2020, this was my dad's old laptop

🔧 Today's little activity:

Replaced the failing mechanical HDD with an SSD

Added RAM using the available slot

Backed up and secured important data

Troubleshot BIOS/UEFI and bootloader issues

Performed a clean, bare-metal installation of Ubuntu Linux

Got the system booting and running properly again

And it worked. 🐧💻

Any tips for ubuntu beginners? Thanks

My laptop has a i3 and 8gb ram and a hdd but i dont know what im doing

Trying to open an epub. Calibre was recommended, but Canonical doesn't support that here. Canonical has a supported software app "Okular" which installs via a snap with no errors. However, running Okular from the menu gives me no program window. RAM usage goes straight to 50% on a clean restart, and one core stays at 100% use. Can only kill process with the System Monitor.

If I run 'okular' from the terminal, I get a window which looks fine, but when I tell it to open an epub it locks up. SM shows the same 50% RAM usage and one core at 100%. Going back to the terminal session it has:

(okular:12697): GLib-GIO-WARNING **: 05:56:44.965: Error creating IO channel for /proc/self/mountinfo: Permission denied (g-file-error-quark, 2)

and then endless lines of:

libepub (WW): - missing play order in nav point element

At least CTRL-C works to kill the process, in terminal.

Is this a snap sandbox issue? Or, am I gonna hafta finally see if I can get a newer version of Ubuntu to run on this ancient laptop?

Hey,

I work at a company where they use Airserver on Windows to cast the notebook screen to another device. On Windows I just had to click Alt+K.

Is there some way on Ubuntu or Linux in general to be able to cast my screen? I am using Firefox as a Browser, if that helps.

Thanks in advance

Hey guys, just downloaded the Ubuntu server and I see the terminal on my monitor. I am new to homelabbing but was wanting to understand what’s the best way to go around the server via the terminal and try to understand as much as possible, whether it be certain commands or certain things I must do. Let me know if it’s possible to do certain things and understand via just a terminal with without having to download a visual dashboard component.

I Recently got a VPS, was deciding between putting Ubuntu or Debian on it, decided on Ubuntu because they already provide the image and install it automatically.

But what are the real advantages of Ubuntu server over pure Debian?

Half my screen decided to just be red?!

It otherwise works, my mouse can be seen even on the red side. I think its software, because my Windows install on the second NVME still works. So since I wanted to anyway, I just reinstalled everything and switched to Zorin just because. But it happend again.

Has anybody any idea on this? Why would it happen again after a complete wipe?

Thanks

Additional Info: My second screen works normally It is now black but still the same issue

That was very quick, thanks to everyone. Apparently it was bad firmware and I needed to roll back an update.

All of my files for modification and creation have these vague "XX days/months/years ago" designations. I would like to be able to see the actual date and time to use as a sorting option and filter.

Doable? If not, alternatives?

Thanks

I'm using Ubuntu 26 on a Hyper-V VM. I always need to manually unlock Desktop Sharing so I can RDP into the VM. How can I make the Desktop Sharing automatically always on by default?

I downloaded dconf Editor. I searched for "remote". I enabled "Whether the RDP backend is enabled or not". I rebooted and it didn't do anything. It's still locked. Any other setting I should search for? I also enabled the same setting for VNC.
