I have installed some configuration mods for my terminal. But I messed some things up, and this is how the terminal now looks like:
And this is how I want it to look like as usual:
(Sorry for the bad image quality) but you get it. A fresh new terminal after you installed Ubuntu. So what is the solution for this?
I'm running Ubuntu 22.04.5 LTS and recently installed FireFox 152 through the apt install channel.
When I open Settings/About Firefox, I see the Firefox updates is set to "Updates are managed by your operating system." There doesn't seem to any longer be a setting to check for updates manually or to notify me that an update is available so that I can chose when to do the update.
I opened about:config and changed app.update.auto from True to False, but that had no effect.
I would like to be able to disable the automatic updates so that I have control over when the updates happen. What are the steps to do this?
Additional info: Prior to today I was using Snap to update Firefox. Something went haywire with the auto update that broke Firefox, so I no longer care to use Snap.
Thanks
I'm listen the gdebi is dangerous but how, this is linux no dangerous software im so much listened so gdebi is so dangerous The Chatgpt Grok and Gemini says its safe but Meta Ai, Deepseek, ChatGPT Viber, says is dangerous
i thinks its fake
So, what I did was running a command:
sudo apt modernize-sources
The following files need modernizing:
- /etc/apt/sources.list
- /etc/apt/sources.list.d/mariadb.list
- /etc/apt/sources.list.d/packages.cloudpanel.io.list
Modernizing will replace .list files with the new .sources format,
add Signed-By values where they can be determined automatically,
and save the old files into .list.bak files.
This command supports the 'signed-by' and 'trusted' options. If you
have specified other options inside [] brackets, please transfer them
manually to the output files; see sources.list(5) for a mapping.

How to fix this error while updating packages?
I am trying to install a program from a dvd on an old laptop but am having a problem with changing the bios system from OS Boot Manager to USB CD/DVD Rom Drive.
I have moved USB CD/DVD Rom Drive to the list of option by using F6 but note that the arrow still remains againstOS Boot Manager, and after pressing F10 to exit and save, the required changes do not take place.
Can anyone help me an 86 year old computer novice, resolve this issue.
Recently my system (24.04) suggests the update Microsoft’s 2011 UEFI and KEK CAs are set to expire in June 2026 and are being replaced by 2023 CAs. This is also discussed at this link.
Is it safe to update or should I ignore it?
Ok, this is seriously impossible. I first tried to download the desktop version onto a 32GB USB stick, but it ran out of space after downloading about 4GB (4,194,268KB, to be exact). This is a brand new stick. Yes, I know that some space is used to help access the rest, but I am SURE 28.8GB is enough space to download 6.1GB. But just to be sure, I decided to try to download it onto a 128GB USB stick. Same problem. The download stopped because it is "out of storage space" after just 4GB. The download works fine when downloading on to my laptop, and only takes up ~6.8GB on my harddrive. What is preventing it from downloading onto my USB sticks? I can guarantee it isn't running out of space.
What's really weird, is that it's just the Desktop version. I've successfully downloaded Ubuntu Server onto the exact same brand 32GB USB stick.
I just swapped out my Microsoft intellimouse Classic with a Microsoft Intellimouse pro because of an issue with tracking on any surface that isn't white. I'm glad to say that tracking is now working. However, my middle-click to paste behaviour is no longer working, and when I middle click, it now brings up the workspace switcher in KDE. I'm running stock Ubuntu 22.04, but then installed the KDE desktop on top. If I plug in my old mouse, the middle mouse button works as expected.
When I googled for an answer, the Google AI told me to remap the buttons using something like:
xinput set-button-map "Microsoft Microsoft Pro Intellimouse Mouse" 1 9 3 4 5 6 7 8 2
However, I tried swapping 2 with every other number in the list, and nothing worked.
I then ran the following command to get a terminal to tell me which mouse button is down:
watch -n 1 xinput --query-state 11
which gives me output like below:
When i hold down on the left and right buttons I see that button 1 and 3 show as down respectively. However, holding down on the middle mouse button does not show any change, but does bring up a panel that appears on the left hand side, with an image of my desktop at the top that says "Default" as shown below:
I must confess that I don't actually know what this is.
Any help on how to get my middle mouse button working how it should be, with the default copy/paste behaviour that Linux has would be much appreciated. This is such an odd issue to have.
I have an SFTP server running on Unbuntu 26.04. I originally built it using password authentication for the individual users. I had all the users in a group that had access to the SFTP directory only, and a few users that also had sudo access. This was working great until it was decided to convert to key authentication instead of password. I generated private keys for the users and put the public keys on the server. I have not disabled the passwords yet. This seems to be working for SFTP but when I try to login through PuTTY from my remote machine (running on Windows 11) it returns an error that states the server allows sftp access only and won't even give me access to my own account. How do it make it so users that have sudo permissions can have full access?

I'm running Ubuntu 22.04 on one of my laptops and suddenly DNS doesn't work. It works on all of the other machines on my network. Addressing nodes on my network by IP works. Pinging google or its nameservers gets no response. Resolv.conf looks fine, resolvd is running. Any ideas?

I don't see anything amiss.
I have a vanilla Ubuntu 26.04 install on a brand new Dell Pro Max 16 (2026). Applications (ex: emacs, firefox) start very slowly. So slowly that the system complains about them not responding multiple times. They are better after running but the whole system feels sluggish, kind of like windows used to. I don't know if that's due to snap but it seems reasonably probable. Aside from installing packages outside of snap are there tricks or techniques for speeding things up?
Is there a way of placing a larger delay on the "not responding" notification? That would help a bit.
Edit/Update:
In answer to questions, my system has 32G of RAM and htop shows that it is only 50% used when my system is sluggish.
I get the timeout messages from (or in regards to) a variety of programs. For example, today Files was also doing it. But the more usual violators are firefox, emacs and zoom. Those also happen to be my most used applications, but...
The terminal doesn't seem sluggish, except to start it up (pop the window). Traditional command-line apps (gcc, find, grep, ls, etc) work fine.
My system's gl2mark score is 4231. Not great but not terrible.
I think my disk is working fine. I ran the benchmark from the Disks menu item in "Show Apps" and got an average read rate of 5.6 GB/s and an average access time of 0.04ms
Hi everyone,
I'm experiencing a strange display issue on my Ubuntu laptop that recently started happening on two different machines (including one at my office).
The Symptom:
Out of nowhere, the built-in laptop monitor completely goes dark.
Immediately after the monitor dies, the OS acts as if the system should go to sleep and suspends the machine.
If I wake it back up and plug in an external monitor, the external monitor works perfectly fine as the primary display, but the OS behaves as if the built-in monitor doesn't exist at all.
The issue is intermittent. A few minutes ago, it suddenly went back to normal and the built-in display worked again, only to die completely a few minutes later.
-It occurs randomly after booting the OS, but never on the BIOS screen.
The display setting shows only one monitor (the external monitor) when the built-in monitor is not working.
Note: The BIOS still successfully recognizes the built-in monitor even when Ubuntu cannot see it.
Because this is happening on two separate physical machines, I suspect a recent software, kernel, or power management update might be causing a conflict or triggering a false "lid closed" event.
System Details:
OS: Ubuntu 24.04
Kernel: 6.17.0-35-generic
Session Type: wayland
Has anyone else run into this recently? What logs should I look into next to isolate whether this is a systemd-logind lid-switch bug or a graphics driver issue?
I have turned my monitor physically in portrait position. I adjusted Settings -> Displays so that the layout for my desktop is okay, but the login screen is still landscape.
I read that this problem could be fixed with following instructions:
sudo cp ~/.config/monitors.xml /var/lib/gdm3/.config/
sudo chown gdm:gdm /var/lib/gdm3/.config/monitors.xml
sudo systemctl restart gdm3
But to no avail, it just does not work. No matter if I reboot or even completely turn off and back on computer. The login screen remains in landscape position.
However gdm displays proper login screen when returning from suspend. This is of course logical since it is not providing multi-user login. Lock screen works as well.
I had my doubts for the monitors.xml solution, since there were no existing monitors.xml file in /var/lib/gdm3/.config/ directory. I even looked into gdm source code and there is no references to monitors.xml at all. So how should restarting could change login screen position according to monitors.xml from user desktop settings.
This is a displaymanager problem which is run by gdm, not a desktop manager problem which has user configuration in ~/.config/monitors.xml. Copying that file into /var/lib/gdm3/.config/ (or anywhere else for that matter) is doomed to fail, I bet it has never worked. The code in gdm is intrested in login screen only for things like user selection, password, fingerprint and id card, not basic geometric transformations like rotate, flip and scale that you find in desktop manager user settings, ~/.config/monitors.xml.
So what now? I guess I have to accept that login screen in gdm-land is carved into stone as landscape position , just like BIOS does.
First of all, these are the laptop's specs:
Model: SAMSUNG LTD. 300E4A/300E5A/300E7A
Memory: 4 GiB
Processor: Intel Core i5-2450M x 4
Graphics: Intel HD Graphics 3000 (SNB GT2)
Disk: 1 TB HDD
It's old (10+ years) and I wanted to give it a new life just for lightwork. I checked and it is not under the supported hardware for ubuntu, but used the Try Ubuntu feature and it works, so I assume that even if it hasn't been tested to be in the supported devices tab it should work just fine.
The problem:
After the install process I rebooted and the PC asked to remove the bootable device and press enter, so I removed the USB flash drive I used and press enter. Now, when I try to boot the PC, it just gets stuck in a loop, trying to boot up. I can't get into the grub menu by holding down the Shift key. The only thing I can do is boot into BIOS in the Boot settings. I only have the option to change the Boot Priority Order. Another device appear on the list besides the HDD. I already tried changing the priorities, but nothing changes.
If I boot up with the bootable USB connected the grub menu appears without any input from me, and only two options are available: "Try or Install Ubuntu", and "Ubuntu (safe graphics)". The first time I clicked on the first option and just reinstalled the OS but the problem didn't go away. I can close the install window if I boot like that again and use Ubuntu as the Try Ubuntu feature, but nothing more.
I already tried different things I found online in forums, but I don't have the exact same issues or menus/options.
For example,I tried the solution in this forum, but I don't have the add customized boot option in my BIOS.
I also tried this one, but I don't have the Advanced options for Ubuntu on my GRUB menu.
The other thing that I tried was Boot-Repair twice. The first time it have back this link: https://paste.ubuntu.com/p/bpsF9b8Nqh/, and said to share it if the problem persists (which it does), and it also gave me this warning.
The second time I tried using Boot-Repair I got this error message: Glade2script-python3 Is Not Responding.
I screen recorded what happens when I turn on the PC with and without the USB:
Video 1: Booting without bootable USB and getting into BIOS
Video 2: Booting with bootable USB
I'm afraid I've gotten myself into something that's way above my understanding (I never used Linux before).

I've done this many times on different systems, but this has me puzzled:
OS: Ubuntu 26.04 Server
Had an external drive that I was permanently mounting using the fstab.
/dev/sda1 /data ext4 defaults 0 0
I removed the drive and of course it rebooted and went into recovery mode. So I edited the /etc/fstab and removed the external drive mount. Now when it reboots, it still hangs up on trying to mount that drive.
Does Ubuntu 26 store the information that is/was in the fstab in another spot? Like a database or other file? I noticed the fstab in Ubuntu 26 is very minimal, so I'm guessing there is some sort of other place that needs to be updated??
Again, this way of mounting the external works just fine. It was a permanent mount on a non-GUI system. It doesn't auto-mount without an entry in the fstab. The question was that it was removed, and fstab entry was removed, but it still went to the recovery prompt.
Okay, so I see I've not been complete with my description. This is a server. The external drive mounted permanently. I had been doing this on my server for a long time (6+ years). I removed the drive because I'm moving it to another server, permanently. After removing the entry in the fstab, and rebooted, it still tried to mount the drive and therefore hung up and dropped into recovery mode.
Which tool to use to take screenshots of areas selected by mouse on wayland, and annotate afterwards?
None of tools that I was using works with 24.04
The scanner in my USB-connected Brother DCP7030 multi-function device stopped working when I upgraded my Lubuntu to 22.04. In an attempt to get it working, I upgraded further to 24.04, but it still refuses to play ball. The printer in the MFD still works fine. I've installed the Brother drivers and fix to run as admin mode from the brother website. https://support.brother.com/g/b/downloadlist.aspx?c=gb&lang=en&prod=dcp7030_all&os=128 but it still refuses to be visible to SANE.

Your USB scanner was (probably) detected. It may or may not be supported
by SANE. Try scanimage -L and read the backend's manpage.

No scanners were identified.
If you were expecting something different, check that the scanner is plugged in,

I just got an HP M110W printer and configured it as per HP Smart and connected it. It prints in Windows, but I use Ubuntu 22.04 (currently) 99.95% of the time. The printer shows in the Settings and, when I try to print a test page, it twitches but nothing prints. I installed hplip and the CUP libraries and can use lpstat, lpq,etc. but lp filename does not work either. I'm desperately hoping someone on this forum can help me print, otherwise I'm going to return the printer. I have run through all the procedures I found on the HP site but their Chat basically told me I'm on my own.
I installed Ubuntu Desktop 22.04 and want to connect through RDP or VNC. I found screen sharing and enabled RDP. I know the IP of the machine, so I gave it a try. Well, it's not working.
I then found that the Xrdp protocol needs to be installed, so I installed it. Still not working. I also read that it should work with Windows 10/11 RDP, so I tried with Windows 10 RDP from the same network, but still not working.
I can ping the Ubuntu PC, that's something.
Is there a proper explanation of what I should do to make it work?
My computer hung up so I forced it to turn off. When it restarted, I had this error message:
The root filesystem on /dev/sda2 requires a manual fsck.
So then I typed in fsck -f /dev/sda1
Then I got a message:
fsck from util-linux 2.37.2
(initramfs)
I typed in "help" and got a long list of commands.
I have no idea what to do that this point. Please pretend I am your grandmother as I do not understand the Ubuntu jargon.
I have read the answer/comments for the thread Diffrence between /etc/init.d/ssh start and service ssh start.
But I need this /etc/init.d method to be working. I have some auto-generated scripts which invoke /etc/init.d method only. Could you kindly provide me some fix/workaround for this?
I'm new to Ubuntu and want to disable the turbo boost. I tried with cpufreq but i cant get it to work. is there any other way to do it.
In windows it was as easy as changing the CPU speed from 100 to 99.
Its quite common that one wishes or has to read lots of PDF files which are intended to be printed, but since one would read them only once, and one wishes to save some trees, one reads them on Acrobat Reader, evince, xpdf or whatever your choice.
It would be an advantage to be able to control the background's color. Instead of black text on white background, I'd like to have a gray background. By googling I just get the inversion of colors as suggestion – which is sometimes even worse for the eyes.
Is there a pdf reader allowing me to change background color (without changing the color of the text)?
Edit: The first comment below suggests it depends on the file. Therefore I added to the title arXiv's.
I just installed Ubuntu 12.10 and I need to make a custom xorg.conf file. By default, there is not an xorg.conf file on my system. I know what I need to write in the config, but I just don't know how to make X load it...
Should I put my custom commands in a file that already exists? Where is it?
Should I make my own xorg.conf file and put it in /etc/X11?
I got some window decorations from KDE-look.org and I went into settings to change it but it doesn't give me the option to install decorations from file. How do I do so, if it's even possible?
