I have a brand new fresh install of Ubuntu 26.04 on a Dell laptop. Ctrl . ("control period") opens up the emoji picker. I would prefer to reserve ctrl . for other functions, for instance it is the default keystroke for my password manager to fill in passwords in a web browser; GNOME seems to override this and the emoji picker pops up. I cannot find the setting to disable the default mapping (I would like to disable emojis completely if possible). I have looked in keyboard settings and ibus-setup. Suggestions?

In Dolphin, I set “Remember display style for each foler”, because I want, say, the Images folder to use “Icons” view, whereas most other folders to use “Details” view. However, this setting doesn't just apply to things like that, and instead applies to other things like “Show Hidden Files” and “Hidden Files Last”. How do I tell Dolphin that I want options like these to apply globally?

For the past 1–2 weeks, I haven't been able to install updates via VPN. I also can't access https://launchpad.net via VPN anymore: “Error: connection refused.”

I have no issues using my ISP's IP address. What's going on? Are VPNs now permanently blocked? I've tried several different ones, and I can't access the site even with the Tor Browser.

Offline PC: Ubuntu 24.04.4

sudo apt update (Online only at this point)
sudo apt install apt-offline_1.8.5-1_all.deb (Online only at this point)

Online PC: Ubuntu 24.04.4

sudo apt update
sudo apt install apt-offline

I tried to install various packages on the offline PC using apt-offline, following instructions I found online.

However, when I transfer the sig file generated on the offline PC to the online PC and try to download the packages as instructed, I get the same message for every package, and the download fails, creating a zip file with 0 bytes.

VERBOSE: http://archive.ubuntu.com/ubuntu/pool/main/m/mozc/mozc-data_2.28.4715.102%2bdfsg-2.2build7_all.deb - 403 - Forbidden

I can download the corresponding deb file by accessing this URL directly from my browser (Firefox) at online PC.

I don't understand why downloading with `apt-offline get *.sig --bundle *.zip` results in a 403 error, even though I can download it from the browser.

How can I obtain the zip file using apt-offline?

Both my offline and online PCs are mostly in their original Ubuntu 24.04.4 state, except for enabling the firewall.

I haven't touched any repository settings. The image used to install Ubuntu 24.04.4 was "ubuntu-24.04.4-desktop-amd64.iso," which was downloaded from the official Ubuntu website.

Both events are scheduled to take place around May 8, 2026.

The following are the details of the execution in the terminal on the offline PC.

Any advices how to debug the issue?

For KDE Plasma SDDM (all names intenionally given here to allow search hits)
The default greeter "maya" uses a tiny CONDENSED "Font" and cannot be set to anything else by normal means, e.g. in /etc/sddm/font.conf .

Now, this looks awful on anything with a slightly modern resolution.
So a change is "urgent"; how to do it?

This appears to be disregarding "highdpi" settings and the scaling referenced in many postings. Here we are at the FONT setting, disregarding SCALING.

Tiny image due to restrictions:

I use this to start a script via double click :

if [[ ! -t 0 ]] && [[ -x /usr/bin/konsole ]]; then
    /usr/bin/konsole -e "bash -c \"$0 $*; read -s -p 'Press enter to continue...'\""
    exit
fi

Via double-click it does open the script and I expect a Terminal will be opened before the respective script will be started.

But sometimes it works, but sometimes not ?

Any idea to improve it ?

Your question has been identified as a possible duplicate of another question. If the answers there do not address your problem, please edit to explain in detail the parts of your question that are unique. End request for edit. Response: My question is about an add-on package set that provides a GUI desktop interface but uses the "standard" Ubuntu 26.04 LTS distro -- NOT a MATE specific distro. I have never used any but the official distro as my base OS environment, with base utilities, whether it be Ubuntu LTS that I currently use and recommend, or Fermilab CERN Scientific Linux that no longer is current but that I used before Ubuntu LTS when it was current and maintained. Once a new production LTS or "enterprise" production release is available and tested in the community (e.g., a few weeks after production release and deployment), I upgrade to current production. Is the above clear? End response.

I use Ubuntu LTS current production in an “enterprise” environment and prefer the MATE desktop GUI environment. I do NOT use the specific Ubuntu MATE release, just the generic LTS production release. For 26.04 LTS to which I shall do an in-place upgrade from 24.04, the MATE desktop states NOTE: MATE Desktop in Ubuntu 26.04 repository is backported from Debian upstream (Debian Unstable). The Desktop has only community support (through e.g., volunteers and enthusiasts), but NO desktop related security updates or features. Does the MATE desktop I currently use maintain desktop related security updates? If security updates are NOT done, I must find another desktop that functions as close to MATE as possible -- any suggestions? I tried several others after the "old" GNOME interface was abandoned, and disliked all -- if I wanted a Mac OS X or MS Win interface, I would choose these. But I want Linux Ubuntu enterprise "hardening" and neither Mac OS X nor MS Win as my primary OS. Again, suggestions?

Postscript: I have read the response of Thomas Ward to Ubuntu-Mate 24.04, help for understanding : No 26.04 LTS version will be released. As for personal "credentials", I am a professor of computer science and engineering in an ABET accredited degree program and I both do research in and teach security as well as architecture, operating system and environment design, testing, and internals, along with the relevant algorithms, theorems, and measurements. However, I do not have the resources to produce a production operating environment, and thus use LTS. Is the entire base release of production LTS tested and "hardened" (not Pro as Mr. Ward makes that issue quite clear), or is it as insecure as enthusiast distros? What about add-ons such as MATE? Is there any GUI desktop environment that is "secure" and not a potential entry point for compromises due to implementation or design defects? Any suggestions would be useful; the obsolete Scientific Linux environment was so "hardened" because it was in use at major research laboratories that could not afford compromises -- not in the business sense of simply money damages including for the loss of personal information, but in the loss or corruption of data and analyses. I fully understand that no complex system is ever fully "hardened" or "secure".

I decided to upgrade from Ubuntu 25.10 to 26.04 today and everything has gone well apart from I now get the following issue when starting any VMs I have, using virt manager:

This is a weird problem. I have two Ubuntu servers. One, running Ubuntu 25.10, is fine, no issues, the other one runs Ubuntu 24.04.4 and is the host for my Apache webserver and postfix/Dovecot email server.

After the last NetworkManager update last week, the use of network aliases no longer work for Ubuntu 24.04.4 server.

For instance if I want to connect to my webserver, www.abcvde.net that resides on the 24.04.4 server, I get a "Destination Host Unreachable." Nor can I use the IP address (192.168.0.22), it times out. However, if I use the localhost alias or its IP, it works. Using the server's own IP, 192.168.0.11 fails as unreachable.

Pinging the alias name, BBB fails, as does pinging its IP. However, I can ping other PCs/servers in my home network using either IP address or the alias.

What is more puzzling, since this occurred at the same time, I'm no longer receiving emails. I believe there's a connection but don't see how. I only have one server set up as a email Dovecot Imap/POP3 server and postfix so I can't just redirect the incoming email packets to another server. Outbound emails work, no issue. Email app is Thunderbird.

I also checked to see that the firewall is off. I'm behind two other firewalls and a NAT. A firewall isn't needed. The router is TP-Link.

Thoughts? Ideas?

Update. Checking with my external mail gateway, mu inbound emails are beging rejected at my end with "400 Network error: Could not connect: No route to host." The gateway confirmed my DNS entries are correct.

As an aside, I can connect to other servers in my private network from outside.

So, some thing happened with that update.

I looked at the Brother website and their directions are the same as on AskUbuntu.

I updated my system from 24.04 LTS to 26.04 LTS. I wanted just to update, not upgrade the Ubuntu version. Don't ask ... I was very stressed and copied some commands without thinking about. Stupid - I know.

My problem is, each time I try to "sudo apt upgrade" I get this error:

I'm new to Linux (about 6 weeks) and have been testing multiple versions of Linux on my NUC which resulted with an SDD with three OS partitions. The sequence of installation was:

1. Windows 10
2. Ubuntu 
3. Winux

My goal: I want to remove Winux from the boot list as I migrate away from Windows and embrace Ubuntu.

My Situation: I've read other posts about multiple OS's and the removal of 1, but nothing seemed to match what I have unwittingly created.

In the PC's Intel BIOS, there are only two entries:

Windows Boot Manager
Winux 11

From Ubuntu using efibootmanager I have the following boot entries:

BootCurrent: 0001
BootOrder: 0001,0000,0002,0003
0000  Windows Boot manager
0001  Winux 11

When I select Winux 11 from the first boot list presented, I see a completely different list of boot options:

Winux 11 GNU/Linux
Advanced Options for Winux 11 GNU/Linux
Memory test (memtest86+x64.efi)
Memory test (memtest86+x64.efi, serial console)
Windows Boot Manager (on /dev/nvme0n1p1)
Ubuntu 24.04.4 LTS (24.04) (on /dev/nvme0n1p7)
Advanced options for Ubuntu 24..04.4 LTS (24.04) 
UEFI Firmware Settings

Now to add more confusion ... from Ubuntu when I list it's boot list:

awk -F\' '/menuentry / {print i++, $2}' /boot/grub/grub.cfg

I get yet another different boot list:

0 Ubuntu
1 Ubuntu, with Linux 6.17.0-23-generic
2 Ubuntu, with Linux 6.17.0-23-generic (recovery mode)
3 Ubuntu, with Linux 6.17.0-19-generic
4 Ubuntu, with Linux 6.17.0-19-generic (recovery mode)
5 memtest86+
6 Memory test (memtest86+x64.efi, serial console)
7 Windows Boot Manager (on /dev/nvme0n1p1)
8 Winux 11 (24.04) (on /dev/nvme0n1p6)
9 Winux 11 GNU/Linux (on /dev/nvme0n1p6)
10 Winux 11 GNU/Linux, with Linux 6.17.0-22-generic (on /dev/nvme0n1p6)

My Concern: I'm confused with the various boot lists and their differing sequences. So using any of the other articles I've read didn't give me confidence to just "try" one of their methods. I don't feel like I could afford to lose my Windows system just yet ... although EOL is coming for it soon!

I have an even older dedicated Linux machine with a GTX-560 on an old ASUS Maximus IV motherboard with an Intel i7-2700K, and after upgrading to 26.04 it still feeds two monitors just fine. (Might be a clue here?); (I am not a gamer, hence the continued use of the GPUs, they are fine for work.)

On my MSI 399 Pro Carbon, 24 thread AMD, with the 760, I have tried to use the 470 Nvidia driver to no avail, and I went back to the recommended Nouveau. Is there a legacy procedure of any kind or software mod to get two screens again on my best machine? Incidentally, the card runs both monitors on the Windows O.S. different drive, both drives are NVMe.

E.T.A.: Oops, (not 'USB'), the monitor feeds are DVI and HDMI direct from GPU, no vid on motherboard. Mea culpa...

I am unsuccessful in establishing a RDP remote login connection to Ubuntu 26.04LTS.
I followed the instructions here. It is a fresh installation of Ubuntu.

As a client I use Remmina. Authentication works, but the screen remains black, with no error. Please see screenshot. The top border of the screen shows some "colors" when looking at it exactly.

In contrast, RDP Remote Desktop sharing works. Connection from other client devices equally do not work.

Remmina logs as follows:

For some reason whenever I try to use Bluetooth on my laptop only one window produces sound while the other only produces sound when the said window is also making sound. I remember I had a similar issue with this in Windows 11, and I'm not entirely sure why it's happening here. The sound page in settings acts like my device works and in pavucontrol when I switch my Bluetooth device between SBC and SBC-XQ it works for about a second and after that there's silence. I'm using a fully installed Kubuntu 26.04. This happens in both pulseaudio and pipewire.

I have a computer running Ubuntu 24.04 LTS desktop where I have QEMU/KVM running. One of the guest OS is Windows 11. This VM has secure-boot on as required by Windows. The secure boot certificates originally issued in 2011 will expire next month. The new certificates were issued in 2023.

The above page shows a table of expiring certificates:

| **Expiring Certificate**                  | **Expiration date** | **New Certificate**                  | **Storing location** | **Purpose**                                          |
| ----------------------------------------- | ------------------- | ------------------------------------ | -------------------- | ---------------------------------------------------- |
| **Microsoft Corporation KEK CA 2011**     | June 2026           | Microsoft Corporation KEK 2K CA 2023 | Stored in KEK        | Signs updates to DB and DBX.                         |
| **Microsoft Windows Production PCA 2011** | Oct 2026            | Windows UEFI CA 2023                 | Stored in DB         | Used for signing the   Windows boot loader.          |
| **Microsoft UEFI CA 2011\***              | June 2026           | Microsoft UEFI CA 2023               | Stored in DB         | Signs third-party boot loaders and EFI applications. |
| **Microsoft UEFI CA 2011\***              | June 2026           | Microsoft Option ROM UEFI CA 2023    | Stored in DB         | Signs third-party option ROMs                        |

It looks like my VM is not using the new certificates. When I check the secure boot status from within Windows guest, it says:

Secure boot is on, but your device is using an older boot trust configuration that should be updated. There is not yet enough data to classify your device for automatic update.

This page says if I see this message then:

Your device might need additional validation before the update can proceed automatically. Visit aka.ms/getsecureboot for more information.

The link takes me back to the original page linked above.

This made me think Windows update failed to work with QEMU's UEFI firmware called OVMF.

The XML tab of the Overview section of the Virtual Machine Manager shows in part:

    <loader readonly="yes" secure="yes" type="pflash">/usr/share/OVMF/OVMF_CODE_4M.ms.fd</loader>
    <nvram template="/usr/share/OVMF/OVMF_VARS_4M.ms.fd">/var/lib/libvirt/qemu/nvram/win11_VARS.fd</nvram>

The files OVMF_CODE_4M.ms.fd and OVMF_VARS_4M.ms.fd have the modified date of December 10, 2025. The file OVMF_CODE_4M.ms.fd is linked to OVMF_CODE_4M.secboot.fd in the folder /usr/share/OVMF/.

I looked at the OMVF UEFI configuration menu and couldn’t find anything regarding the secure boot certificates or anyway to add new ones.

Here is the Windows 11 System log:

My searches have led to some solutions for Red Hat, and Proxmox, but nothing specific to Ubuntu.

From the Linux perspective most solutions refer only to updating to the Microsoft UEFI CA 2023 certificate. I have not seen anything on how or if one should update the three other certificates expiring in 2026 when running Windows in a VM.

Q: How do I make sure that the OMVF is using all the secure boot certificates from 2023 so that Windows 11 works as expected beyond June 2023?

Thanks

I recently installed Ubuntu 26.04 and I noticed that the thumbnails for my comics aren't showing in the Files file manager. I tried installing different thumbnailers, but nothing seems to work. Instead it just shows the default Ubuntu document icons.

I do not have Evince or mcomix installed. I'm using the default document reader that comes with Ubuntu 26.04.

I'm experiencing an issue with my earbuds on Ubuntu 25.04 and I am on the latest kernel version 6.14.0-32-generic and the earbuds I am trying to connect to is Redmi Buds 6 and that issue not only happens on Ubuntu but Other Linux Distros like Arch Linux, Pop!_Os and Fedora. I am currently using pipwire.

Unlike normal bluetooth connection, when the bluetooth is connected there will be a sound that notify the state of being connected but now I there's no notification sound from earbuds and I have tested with other operating system like old arch Linux kernel and Windows they both works.

I am able to search my bluetooth device. I am able to connect via bluetoothctl.

I've been stuck on this for 5 days now, so any help would be appreciated> This is a bare metal server on OVH running Ubuntu 22.04. The OS was installed on a RAID1 array using both "system disks" (these are regular SSDs). The issue appears when creating a RAID10 array of the 6 "data disks" we have (these are nvme disks). Upon creating the partition on the array (ext4), mounting it and amending fstab and mdadm.conf, the OS will not boot. Here's the lsblk printout:

OS is fully updated. Tried:

1. Adding "resume=none" in /etc/initramfs-tools/conf.d/resume
2. Blacklisting btrfs in /etc/modprobe.d/blacklist
3. Commented out "GRUB_CMDLINE_LINUX="nomodeset iommu=pt console=tty0 console=ttyS0,115200n8" (not sure why this exists, it was added there by the default OVH installation)

No matter what I try, the OS always gets stuck on the same line. I can enter recovery mode and play around with files, I just cannot boot the system.

I seek an editor where Ctrl+C copies, Ctrl+X cuts, Ctrl+V pastes, Ctrl+Z undos, Ctrl+Y redos, F3 searches and F2 renames. When I click the left mouse button, the cursor should go there. All modes should be active at the same time (command and insert and ...).

Also Ctrl+W closes the current tab in tabbed interfaces, Alt+F4 closes the currently focused app, Ctrl+Tab tabs between guess what, tabs, Ctrl+O brings up open dialog, Ctrl+P brings up print dialog,

What Linux editor exists out there that can be used in the terminal and has that behavior?

The mouse cursor disappears after a while. It happens randomly with any software (Chrome, Skype, terminal, LibreOffice etc...). The mouse still works though.It just the cursor which disappears.
I cannot find a pattern why it disappears or what makes it disappear. The only fix is to reboot (logout does not work). It works for a while after the reboot, then it disappears again. It only disappears when I move the mouse which makes me thing it could a be GPU driver bug (the screen is not redrawn correctly). I could be wrong obviously.

I've tried standard login and Wayland. It happens with both. I guess it's related to the hardware as I tried the same Ubuntu version on a different computer with an Intel GPU and it does not occur on it.

Only Ubuntu is installed on the drive (macOS is not). Ubuntu detects the GPU as Rv730.

Is there a way I can bring the cursor back without rebooting?

I was trying to enable DNS over TLS via systemd-resolved. I changed /etc/systemd/resolved.conf as follows:

[Resolve]
DNS=1.1.1.1
#FallbackDNS=
Domains=~.
#LLMNR=no
#MulticastDNS=no
#DNSSEC=no
DNSOverTLS=opportunistic
#Cache=yes
#DNSStubListener=yes

While monitoring the network (with tcpdump) to see if the resulting behavior was the intended one, it seems that a TLS session is established with the target server; but, then the server closes the connection. I get the same results with 1.1.1.1, 8.8.8.8 and others.

Any ideas on how to fix this?

P.S.: systemd-resolved ends up doing parallel resolution with traditional DNS (despite the setting of "Domains" above). But my main question for this post is what may be going wrong with the TLS one.

Since the update yesterday (yes, the linux update), eclipse denies me to run even the most simple helloworld:

has been compiled by a more recent version of the Java Runtime (class file version 53.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Full error text:

I tried to update the JRE (and JDK):

• window -> preferences -> java -> installed JREs. I could check: java-8-openjdk-amd64 (which is currently) or java-11-openjdk-amd64.
• window -> preferences -> java -> compiler. Compiler compliance level is set to 1.8 (it doesn't know java 11. It does know java 9.)
• window -> preferences -> java -> Installed JREs -> Execution Environment. When clicking on JavaSE-1.8 in the left list, 2 options appear in the right one: java-8-openjdk-amd64 and java-1.8-openjdk-amd64. First one is checked. (But I don't think, that matters, because these should be the same.)
• I tried to update eclipse. (No updates available)

So anything is set to Java8. Why does the error still occur?

Btw, some of my projects (the helloworld including) are marked with a red exclamation mark, but the error appears in any project, not in these only.

• I use XUbuntu 18.04 now (before the update anything worked fine)
• I use eclipse Photon
• I use java standard API only
• I use git and the eclipse git plugin

I want to use a wireless printer from another network, it's own. As of 17.10, if I connect to that network, the printer shows up almost instantly.

How can I configure Ubuntu to use the printer's network for that printer, even when connected to another WiFi network?

If it makes a difference, the printer is a Samsung M2825DW

I have successfully installed steam and dota2. But when I try to play dota2 this pops up:

Unable to start game.
Failed to create OpenGL context. Your graphics card must support at least OpenGL v3.1

My OS is 14.04 LTS 64 bit. My hardware is:

• ASUS H170 Pro gaming MoBo;
• Intel Core i5 6500 Skylake
• 16 GB Ripjaws RAM 2400 CL15;
• Gigabyte GeForce GTX 960 2GB OC Windforce;
• 1 TB western digital 7200 rpm.

How can I fix this/what should I do?

Adobe released an open source font family called "Source Code Pro" (download here, Slashdot article here). How do I install it?

In Unity Ubuntu 11.10 how I can have a screenlet with a list of tasks to do?

For example:

1- Update system.
2- Check mailbox.

and so on.

Thanks in advance.
