I have recently returned to Linux after a long hiatus, currently using Ubuntu 24.04.4LTS.

I have a large collection of images that I would like to sort and arrange but I am having problems with thumbnails showing up in the file manager (Gnome Files 46.4). Some photos do generate a thumbnail, but most simply give me a purple, generic icon. To make it more difficult for me to understand, some of my folders show thumbnails for all photos in that folder, but then a sub-folder doesn't display thumbnails at all. This problem seems to be irrespective of image file type.

When I open an image in the image viewer (Gnome Image Viewer 45.3 or Eye of Gnome 47.0), the image displays properly, but the thumbnails of the other images in the folder do not display at the bottom of the window.

Without thumbnails displaying consistently in the file manager, it is impossible for me to manage my image files. Is there a solution, or perhaps a better file manager?

I have an old Core2Duo I use as a media server with Turnkey Linux installed which originally had a 1TB drive and then I cloned to a 2TB hard drive. Later I cloned to a 3TB hard drive and had to do some workarounds to get it to work (BIOS bridge partition?).

Now I have a newer i7 4th gen PC (HP Pavilion 500) with an 8TB hard drive and I want to move all the data to.

I did try cloning/resizing the drive but I can't get it to boot.

I also tried installing Debian on the new computer (Debian will boot) and then formatting the main partition and rsync-ing the data across but wouldn't boot.

I followed various AI advice about using grub-install but it will not boot.

If I install Turnkey Linux fresh it will not boot.

Research leads me to believe that these early HP computers have issues with BIOS and UEFI.

I have tried legacy enabled and disabled and secure boot is off.

Once I installed Debian with UEFI then installed Turnkey over the top without changing partitions and after some grub-install magic it worked but when I tried to reproduce the same steps so that I could do the same for my real Turnkey installation I could never get it going again.

When it doesn't boot it either says no bootable device or goes to the grub prompt. At the grub prompt I can manually get it to boot depending on which of the above methods I used.

Not sure what my actual question is, maybe this is just a rant after a week of trying to make this work and 15 hour copies/clones, but I would appreciate any advice to make this work on a HP. Preferably without any suggestions to start fresh and copy my data across.

NONE of the AppImages work

I'm using 26.04 LTS.

I'm using AppImage with a lot of applications.

None of them work. I installed Fuse, and only one works; the rest don't. They say this.

No LTS by Ubuntu-Mate, no hesitation, please only indicate the current state. I would prefer it would be going on.

I am experiencing severe lag and intermittent freezing after resuming my laptop from suspend on Ubuntu 26.04 (Resolute). The system becomes almost unresponsive for a period of time or requires a hard reboot.

My System Specs:

• OS: Ubuntu 26.04 LTS (Development Branch)

• Kernel: 7.0.0-14-generic

• CPU: AMD Ryzen 5 4600H with Radeon Graphics

• GPU: NVIDIA GeForce GTX 1650 (Laptop)

• Driver Version: 580.142

• Display Server: Wayland

• RAM: 32GB

What I have tried so far:

1. Disabled the following NVIDIA systemd services to see if it bypasses the hang during resume:

   • nvidia-suspend.service

   • nvidia-hibernate.service

   • nvidia-resume.service

2. Verified that nvidia-persistenced is active (running).

3. Updated GRUB and checked the memory sleep state.

Observations:

• I am running a hybrid graphics setup (AMD + NVIDIA) on Wayland.

• The issue persists even with the 580.x and 590.x driver series.

Question:
Has anyone encountered similar freezing issues with the 7.0 kernel and NVIDIA 580 drivers? Is there any way to fix this issue?

I am trying to set up LVM on a new NVMe drive, but the pvs command returns no output (or does not show the specific device). I have confirmed the device is visible to the kernel via lsblk.

System Information:

Why is LVM failing to recognize this NVMe partition as a Physical Volume?

I have an ASUS TUF Gaming F16 with an RGB backlit keyboard. How can I configure the COLOR of the keyboard and any effects, not just the brightness? I hate the default color changing effect and I just want it solid green.

GSK_renderer=cairo significantly reduces the memory usage of GTK4 apps.

I am thinking about applying it to some of my low-end computers by adding it to /etc/environment. However, I don't want to turn off system-wide hardware acceleration.

By any chance, does this environment variable stop system-wide hardware acceleration, or is it only for GTK4 apps?

I recently 'upgraded' to Ubuntu Studio 26.04

When I was using the webcam, I noticed that the display seemed to have higher contrast than before. I downloaded guvcview and saw that the contract was up to 95. I lowered it and the webcam view looked as it did before installing the new OS.

The I noticed that this change affected webcamoid also, and also when I had a Teams video call. Why the global effects?

Also I removed guvcview and the config file and the changes still persisted, even after a reboot. I would just like to understand why this is.

I used Obsidian software on ubuntu 25.10. I did a test before production with 26.04. I install obsidian just after installing os; obsidian is ok; I reboot ubuntu and obsidian does nothin when I launch it; do you have an idea?

When I open the location of root on my NVME drive in Nautilus where ubuntu is installed I get:

Error mounting /dev/nvme0n1p8 at /run/media/ubuntu/OS:   wrong fs type,bad option,bad superblock on /dev/nvme0n1p8,missing codepage   or helper program,or other error.

Tried fsck, didn't helped

I have Firefox pinned to my plank dock. Since the last snap update (April 2026, Firefox 150.0 (64-Bit) Snap for Ubuntu canonical-002-1.0), when I open Firefox the opened window creates a new temporary icon on the outer section of the plank dock where normally programs, that are not pinned to the dock, place temporary icons while open. If I open another Firefox window this window is added to the new temporary icon, so that I can switch between them with right-mouse click. However, with a right-click the usual option to pin the icon to the dock does not exist.

The dock launcher in home/user/.config/plank/dock/firefox_firefox.dockitem shows:

Searching for a solution I found this post on a similar problem with Chrome browser plank has duplicate icons for added launchers in LXDE that points to change some entry names in config. Maybe something similar helps with Firefox? Any help is welcome.

Is there any way to alter the order of the days of the week in Ubuntu without altering the locale specifications? I am using the English version, and the order of the days of the week are:

Sunday, Monday, Tuesday,..., Saturday.

That is rather confusing for me, because I am more used to weeks starting on Monday and finishing on Sunday. I have navigated all the Ubuntu options that I could think of, and search on the web, but almost all answers that I see are about changing the display of the date and time in the top bar. I do not want to modify this, but the order of week days in the expandable calendar of the month that appears when you click on the date so that they are:

Monday, Tuesday,..., Sunday

Any help will be very welcome, of course.

I’m testing Ubuntu 26.04 with Btrfs and noticed that the installer creates a flat Btrfs layout (no @ and @home subvolumes), unlike Kubuntu which sets them up by default.

This causes issues with tools like Timeshift that expect the standard @ layout.

Question:
Is there a supported or recommended way to install Ubuntu 26.04 with Btrfs using @ and @home subvolumes during installation (without manual post-install restructuring)?

Alternatively:

• Is this behavior intentional in Ubuntu’s installer?

• Are there plans to support a proper Btrfs subvolume layout like Kubuntu?

• What is the best practice for users who want snapshot-based rollback (Timeshift/Snapper) on Ubuntu?

Any official guidance or recommended workflow would be appreciated.

With Ubuntu 24.04, I used the Software & Updates app to set the update frequency, schedule updates or stop them completely and do updates manually. (This is a requirement I have since I have limited bandwidth.)

I did the same for Snap with CLI commands that are well-documented. But for others, I'm a bit lost as the Software & Updates app is gone now.

Also, I know the Software & Updates app can be reinstalled, for now. But I'd like to know an alternative solution first, since they might ditch the Software & Updates app altogether in the future.

I use ufw on ubuntu 22.04 and I've noticed that iptables -L -v -n -x and nft list ruleset both show the same rules.

Here is what I have

# ufw --version
ufw 0.36.1
Copyright 2008-2021 Canonical Ltd.

# iptables -V
iptables v1.8.7 (nf_tables)

# nft -v
nftables v1.0.2 (Lester Gooch)

I'm trying to understand, does ufw use nftables directly or does it use iptables and rely on iptables-nft to use nftables ? Like trying to understand if ufw has been converted to be nftables native and it is creating these duplicate rules itself or if ufw doesn't even know nftables exists at all and iptables-nft allows ufw to transparently use nftables?

Does the answer change based on the version of ufw in use?

I just updated from Ubuntu 20.04 to 22.04 and it looks since then Firefox can't open a file. When I download a file from a website, I get the dialog box "Open with... System Handler (default)". I try that and it looks the file is downloaded but I can't open it or even access the folder when it was downloaded. I have Firefox 105.0.3 (64 bits) Mozilla Firefox Snap for Canonical-002 - 1.0

Anyone able to help with Steam Rom Manager

Application is throwing this error on Ubuntu 19.10:

Warning! No user accounts found, it could be due to one of the reasons below:

incorrect Steam directory;

Lets say I have a process which has session id 10030, Is there any way to remove the current process from this session and assign it to another? Or at least remove from this session? I've read this:
The session's ID is the same as the pid of the process that created the session through the setsid() system call. That process is known as the session leader for that session group. All of that process's descendants are then members of that session unless they specifically remove themselves from it.

But unfortunately I could not found how "they specifically remove themselves from it" can be done. Hope you can help. thanks.

Are Ubuntu builds deterministic? I assumed they are, that is, if I recreate the process of building Ubuntu installation media, I will get the same image, (bit-for-bit, with the same checksums) as the one on the Ubuntu mirrors.

Recent post by Joanna Rutkowska (lead developer of Qubes OS distro) suggests that it isn't so:

currently most projects, including all Linux distributions, do not build deterministically

Why not?

I have an image, about 300x300 pixels large. I want to print as many copies as possible on a single page (I am planning to cut them apart with scissors afterwards).

Is there a way to do this? Is there a way to generate a PDF with copies (without opening something like gimp and manually doing copy-paste work).

For a given hardware configuration, how do I find out if Ubuntu will run on it? What considerations should I take into account when choosing an Ubuntu version and flavour such as:

• Xubuntu with a lighter desktop than the usual Gnome and Unity
• Lubuntu with the even lighter LXDE desktop

Obviously Ubuntu does not run on some processor architectures. So how do I go about choosing the right version and derivate. How can I find out the minmal system requirements?

I am running an HP pavilion dv6000 dual boot win7 and Ubuntu 12.04. (well, up until today). After a reboot, the boot process drops to the BusyBox shell and I end up at the prompt:

BusyBox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash)
Enter 'help' for a list of built-in commands.

(initramfs)

I've been researching others who have had this same problem, but haven't been able to find any of those solutions to work for me.

I tried the method described here, and after the final command

mount -t ntfs-3g /dev/sda1 /root -o force

it does nothing and gives me another (initramfs) prompt.

I can boot to a live CD (USB) and get to a terminal, but it doesn't seem to do much good, as I can see the /dev/sda1 in the ls command, but it doesn't recognize it when I try to cd to it.

One more question: using the command fdisk -l how can I tell which mount point (sda1/sda2) is my windows partition and which one is Ubuntu?

my problem is that when I insert a drive (HDD partition, DVD etc.) a notification appears, which has a unlimited duration.

Clicking somewhere (except the options) will close this notification, but it is bothersome that I always have to use the mouse.

Is there a way to close these notifications with the keyboard or to set a duration?
