If open up GEdit, type some stuff, and click "Save As", the directory that the file saving dialog starts in is ~/Documents. How do we change that?
Roughly similar questions have been asked before, but they're a decade old.
After I tried installing custom drivers to get a Tp-Link usb wifi receiver on ubuntu (did not work, got to use another device, but that's another matter ;) ), I got several new problems with Ubuntu and espacially the File Explorer (which is called Nautilus if i'm no wrong). First, now if I hit 'delete' key on a file, instead of putting the file to the trashbin, it's destroys it permanently. I don't know why, and I don't know how to change it back. Another thing is related to PNG image files. For whatever reason now I can't open PNG files in nomacs or GIMP (nomacs terminal give a segmentation fault error on every png files. Jpg, tif, bmp.. works) and if I try to right click on any png file in the explorer and open the property window, the explorer close completely. (property panel opens correctly for any other files) and finally I installed another image viewer after this incident, 'Viewnior', and it opens correctly png files.
it looks like a joke (you try to install drivers for a usb wifi key, and then you can't open png files anymore...) but that's what happened.
the main clue here is that I got a Segmentation Fault Error while opening png file in nomacs. It seems to be a pretty broad spectrum of errors in ubuntu. Does someone have any clue of how I cant diagnose the problem more closely and how I can try to fix it ?
I am using Ubuntu 25.10 (GNOME / Wayland) with fully up-to-date packages. Remmina version is 1.4.40 (git n/a).
Recently, Remmina started having frequent crashes while using an remote session or during initial connection to a remote server. System log messages during this crash:
org.remmina.Remmina.desktop[55066]: realloc(): invalid next size
org.remmina.Remmina.desktop[55062]: Aborted (core dumped)
I'm trying to figure out why MATE 25.10 refuses to boot through grub.
Here is its entry in the 40_custom file:
search --no-floppy --set=root -f /videos/ubuntu-mate-25.10-desktop-amd64.iso
set isofile="/videos/ubuntu-mate-25.10-desktop-amd64.iso"
loopback loop $isofile
linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=$isofile noprompt noeject --
initrd (loop)/casper/initrd
It works for other Linux iso files. The mate iso filename is correct, as it is located in the /videos directory.
When I try to boot, the computer just reboots.
Currently I am using Ubuntu 24.04, but I am also wondering if the same could be applied to 22.04.
On my machine I have a Secure Boot certificate that is invalid after Oct. 19, 2026. From my research I've found that this should be automatically updated with the shim-signed-package. And running sudo apt full-upgrade should take care of this issue.
Sadly none of the above seem to work on my computers since shim-signed is already at the latest version.
I understand that it is a while until the certificate is invalid and that the machine will keep booting after the certificate is expired until the kernel or grub is updated, but since my newly installed machines come with the newer certificates I feel like there should be a way to update my older machines as well. And not updating is sort of like gambling that I will receive an update before Oct. 19.
sudo fwupdmgr update does not update the certificates either.
The commands that I'm using to check which certificates are installed are mokutil --db and mokutil --kek.
I have a weird bug since yesterday when I try to open images (png, jpg, ...) with some image viewer, for example with shotwell :
$ shotwell image.png
fish: Job 1, 'shotwell image.png' terminated by signal SIGSEGV (Address boundary error)
The weird thing is that I can open it using eog image.png without any problem.
I have the SIGSEGV error using the following programs :
shotwell
gthumb (opens the image then crash after 2 seconds)
gimp (opens the program but not the image - instead displays errors related to file-png and file-png-load)
I don't have the error using :
KolourPaint
Gnome-paint
Brave/Chrome/Firefox
ImageMagick
Feh
Eog
The type of the image does not to seem to be relevant : same success/errors with png and jpg files.
The error did not occur after an update. I also tried to update (apt-get upgrade), but no changes.
OS : Ubuntu 22.04.5 LTS

Would you have any idea of what's happening ?
Thanks
Edit :
As pointed by @FedKad, this is a duplicate with Multiple image apps (Gwenview, GIMP, gThumb) crashes when pasting/open image after libexiv2 upgrade

I'm suddenly unable to open most images formats with the usual apps.
"Procedure 'file-jpeg-load' returned no return values"The last mod I did to the system (besides the 24.04.1->24.04.4 upgrade) was upgrading darktable (5.0.0 to 5.1.4) and adding dnglab. Did that somehow corrupt some mime type configuration?
For some days or weeks my chrome changed behavior to the worse.
When I click on a link in my Thunderbird (or in a PDF file or just opening a HTML file), chrome opens this in the worst possible window (a window which is even on another workspace).
Earlier chrome always chose the last active window, which is my wanted behavior. Now it seems that it always opens it in "window no. 1"
Since I always have several windows open scattered over different workspaces, this is really annoying.
Is there any workaround to restore the old behavior?

On boot to desktop: I receive the error TEN (10) times upon reboot to a fresh desktop. On said desktop there are TEN (10) icons that do not have generated thumbnails.
Upon opening Dolphin file-browser or any image with the *default image viewer, produces the same error. In this case "Tacent View". UI or command line.
Another scenario: After opening N (any) random number of images, on occasion the system will halt any application attempting to open images with NO ERROR. The app UI simply wont open.
GIMP Tacent View Kirta Gwenview InkScape Further, any navigation to a directory in dolphin file browser that contains any thumbnails WILL produce the equal amounts of the same error as above.
I have attempted to clear the thumbnail cache as well as the Baloo index (commands below), followed by a reboot with NO success:
Thumbmails: rm -rf ~/.cache/thumbnails/*
Baloo index: rm -rf ~/.local/share/baloo
What additional information do you require? I will provide. Is this a bug with libexiv2* ? What is the solution?

Say I have a single Autokey script foo.py, and it can be activated by two different hotkeys: Ctrl-A or Ctrl-B.
Is there a way in foo.py to determine which hotkey activated it?
I switched to Ubuntu yesterday, and noticed that when I press the mute/unmute button on my keyboard, although it works, the light doesn't come on.
I have an HP Laptop 15-fc-003ca with AMD Athlon silver 7120u and integrated GPU. It was working on all other OSs (it's a Windows laptop).
It seems that whenever I connect a USB stick or external drive it appears twice in the Files app, even though the device does not have multiple partitions. Occasionally one of the entries shows errors such as "cannot locate" or "permission required". I am able to access the data through one of the entries, but the other is where the problem is.
When I try to unmount the device the system sometimes refuses or it asks for administrator permissions, requiring me to enter my password. This issue started after I used a USB stick to boot Ubuntu, although I later reformatted this drive using my phone.
I’m not sure what caused this behavior or what I might have done incorrectly.
I have no clue what triggered this. Debugging information appears below. I'm hoping that it will go away or get fixed, whatever it is.

I have Kubuntu 24.04. Suddenly today I am having issues opening certain files with GIMP and Gwenview. In GIMP I get this error:
and in Gwenview I get this in KSystemLog:
KCrash: Application Name = gwenview path = /usr/bin pid = 14079
KCrash: Arguments: /usr/bin/gwenview
I can open .gif and .tga files in both programs. It looks like .webp will open in GIMP but not Gwenview. In Gwenview it instantaneously crashes when I try to open .png or .webp.
Before today I had no issues with opening any of these files with either program. I tried reinstalling both programs in Synaptic Package Manager and still get these errors. I'm not sure what to try next.
I am using Ubuntu 25.10 Desktop (GNOME / Wayland) with all packages fully up-to-date. The GIMP version is 3.0.4.
GNU Image Manipulation Program starts normally. However when I try to create a new image, I get the following errors:

with application crash.
Similarly, when I try to open an existing JPEG file, I get:
gimp.desktop[29914]: /usr/lib/x86_64-linux-gnu/gimp/3.0/plug-ins/file-jpeg/file-jpeg: fatal error: Segmentation fault

gimp.desktop[29872]: /usr/lib/x86_64-linux-gnu/gimp/3.0/plug-ins/script-fu/script-fu: fatal error: GIMP crashed
with application crash.
I tried the following:
~/.config/GIMP;apt remove --purge gimp ; apt install gimp)None of these changed this behavior.
Please note that I am not a regular user of GIMP, but I did not previously encounter such problems with it.
Has anyone with a similar setup experienced the same problem? I am 80% sure that a have used GIMP with no problem in Ubuntu 25.10 on my system; my guess is that a recent update in some package(s) is causing this crash.

Is there any way to update system time / sync it with NTP before Ubuntu One login?

Searching for that error on the internet, it says to install the following packages:
libcamera-ipa
pipewire-libcamera
but neither of these packages exist in the repository.
Next I tried to install pipewire:
sudo apt install pipewire

Where do I go from here?
when I open Ubuntu Software in the Updates panel I see "core 22 20230725", but when I click update I got the message in the title. The exact message I got is: "Impossibile aggiornare core 22: snap has no updates available", because it's in Italian, so I don't know exaclty which is the message in English. I've tried "sudo apt update && sudo apt upgrade", which worked correctly but did not change the situation. I've Ubuntu 22.04 Thanks for any suggestion

Hey there! A friend advertised mpv to me as the holy grail of media players, so I installed it, and I was wondering how to set a custom shortcut for going to the next file in a folder! Example:
name@computer:~/Videos$ ls
1.mkv 2.mkv 3.mkv 4.mkv
name@computer:~$ mpv 1.mkv
mpv now opened. We are playing the file 1.mkv. I wanna set a custom shortcut, on F11, to play the file 2.mkv. If I then pressed F11 again, 3.mkv should play.
I already modified the default shortcuts by doing:
name@computer:~$ vim ~/.config/mpv/input.conf
and writing:
d add speed 0.1
s add speed -0.1
+ add speed 0.5
- add speed -0.5
ENTER add chapter 1
and stuff like that. It all worked flawlessly, and was very intuitive. But now I've hit a roadblock. I tried to add the functionality I described above, but couldn't. I looked everywhere, at the mpv website, at the github page, but nowhere could I find how to do this. There were options like "playlist-next" and "playlist-prev" but they didn't work at all, even tho the described functionality was "skip to the next/previous file". input.conf on github
So my question is: What do I have to do (or write into input.conf) in order to have a shortcut to go back and forth between video files in a folder?
Thanks in advance!
I'm using KDE Plasma 5 right now, and I noticed that the keyboard shortcut Meta + Tab is used to switch between Activities, and Alt + Tab is obviously used to switch between windows. I would like to know if there's a similar way to switch between virtual desktops, and if so, how I can set Meta + Tab to toggle it. I only have two virtual desktops, each with a bunch of specifically positioned windows in them. I'd like something more efficient than clicking on the Pager widget every time I want to quickly switch. I'm a bit new at this, so I apologize if I'm obviously doing something wrong. Thanks, community!
I have always had a network share with my nas (Alt-F) setup in Ubuntu. To access it I allow port 137&138udp in and out and 139&445tcp in and out within ufw. Since upgrading to 20.04 those rules don't work anymore. I have to turn the firewall off to be able to see the share. Once it is mounted and the folder opened I can turn the firewall back on and it works as normal but to be able to see it on the network or open the main folder initially I have to turn off the firewall. Is there another port that now has to be opened in 20.04? The other strange thing is that if I turn SMB1 off on my NAS I can't see the share in Ubuntu, if I turn off SMB2 I can see it but I can't mount any shares, so both SMB1 and SMB2 both have to be activated so that I can see the share (SMB1) and mount it (SMB2). I have always had this working from versions 10-18.04 and in 20.04 is the first time I have had this issue.
I'm new to this site and this OS "Ubuntu"
so I have problems with wifi and bluetooth..
I just check the logs and finally think the problem is related to firmware..

my laptop model is hp 15-cs3012tx and version of Ubuntu is 16.04 LTS I just searched of my adapter model, it says
Intel® Wireless-AC 9560 802.11a/b/g/n/ac (2x2) Wi-Fi® and Bluetooth® 5 Combo
so I just downloaded intel ac 9560 firmware to install
1. OVERVIEW
The file iwlwifi-5150-2.ucode provided in this package must be
present on your system in order for the Intel Wireless WiFi Link
AGN driver for Linux (iwlagn) to operate on your system.
The "-2" in the filename reflects an interface/architecture version number.
It will change only when changes in new uCode releases make the new uCode
incompatible with earlier drivers.
On adapter initialization, and at varying times during the uptime of
the adapter, the microcode is loaded into the memory on the network
adapter. The microcode provides the low level MAC features including
radio control and high precision timing events (backoff, transmit,
etc.) while also providing varying levels of packet filtering which can
be used to keep the host from having to handle packets that are not of
interest given the current operating mode of the device.
2. INSTALLATION
The iwlagn driver will look for the file iwlwifi-5150-2.ucode using the
kernel's firmware_loader infrastructure. In order to function
correctly, you need to have this support enabled in your kernel. When
you configure the kernel, you can find this option in the following
location:
Device Drivers ->
Generic Driver Options ->
Hotplug firmware loading support
You can determine if your kernel currently has firmware loader support
by looking for the CONFIG_FW_LOADER definition on your kernel's
.config.
In addition to having the firmware_loader support in your kernel, you
must also have a working hotplug and udev infrastructure configured.
The steps for installing and configuring hotplug and udev are very
distribution specific.
Once you have the firmware loader in place (or if you aren't sure and
you just want to try things to see if it works), you need to install
the microcode file into the appropriate location.
Where that appropriate location is depends (again) on your system
distribution. You can typically find this location by looking in the
hotplug configuration file for your distro:
% grep \"^FIRMWARE_DIR\" /etc/hotplug/firmware.agent
This should give you output like:
FIRMWARE_DIR=/lib/firmware
If it lists more than one directory, you only need to put the
microcode in one of them. In the above example, installation is
simply:
% cp iwlwifi-5150-2.ucode /lib/firmware
You can now load the driver (see the INSTALL and README.iwlwifi provided with
the iwlwifi package for information on building and using that driver.)
this is the attached document with the firmware file
I typed the command and it showed like this
grep \"^FIRMWARE_DIR\" /etc/hotplug/firmware.agent
grep: /etc/hotplug/firmware.agent: No such file or directory
but in the document it was supposed to be like this
% grep \"^FIRMWARE_DIR\" /etc/hotplug/firmware.agent
This should give you output like:
FIRMWARE_DIR=/lib/firmware
I can't install this firmware with the way above.. and I think this 9650 device is related to wifi and bluetooth..
could someone pls give me a hand to install this firmware..?
thank you for your hand in advance
edit) I also included logs with command dmesg|grep -i firmware
After a recent KDE update in Kubuntu 19.10 I lost the ability to control volume using my laptop keyboard specific volume buttons. It turns out that for the volume control via keyboard to be restored I'd need to launch the KDE Audio Volume widget. Yet, I didn't find this widget in KDE widgets.
So how does one reload this widget by hand?
I upgraded from 18.04LTS to 19.10. However, postfix with SASL (cyrus) has stopped working. It is configured as a smarthost/relay for smtp.office365.com:587 using the normal methods as described widely.
Without debug settings, there is an usual "invalid parameter" error in the log:
Nov 17 00:15:21 ianb-pc postfix/smtp[2277]: 939A25A20DB: SASL authentication failed; cannot authenticate to server smtp.office365.com[52.97.133.242]: invalid parameter supplied

After some debugging, below is a section of mail.log at level 4.
Any ideas? Thanks for any help. Ian

I am following this guide to install Linaro on my Ubuntu 18.04 machine (64-bit Duo core). Unlike the guide, I want to have the latest Linaro version. Thus, these are the commands I use:
sudo apt-get install aptitude
sudo apt-get install gcc-multilib
wget -c https://releases.linaro.org/components/toolchain/binaries/latest/arm-linux-gnueabihf/gcc-linaro-7.3.1-2018.05-x86_64_arm-linux-gnueabihf.tar.xz --no-check-certificate
tar xf gcc-linaro-7.3.1-2018.05-x86_64_arm-linux-gnueabihf.tar.xz
export CC=`pwd`/gcc-linaro-7.3.1-2018.05-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-
{CC}gcc --version
It fails at the last line, complaining:
{CC}gcc: command not found
Can somebody enlighten me? What have I done wrong? This process previously failed when I used Linaro 6.4.1 as in the guide. Thank you so much in advance.
As N0rbert pointed out, I put the $ in there. The output is:

Linaro is nowhere to be found. How does that export command work, and why is not not doing what it should?
Title pretty much says it all. lspci -v finds a sound card, but neither aplay -l not pacmd list-cards don't. Problem first surfaced when updating ubuntu to 18.04, which was a hail-mary attempt to fix an another probably unrelated issue with my login screen. I'm not sure whether or not my sound was working before the ubuntu update either, since the login screen issue arose when I got my machine back from warranty repair.

Things to note:
Have tried:
~/.config/pulseEDIT: inxi -a sees the card and states that it's using the snd_hda_intel driver.
The Chromium B.S.U. arcade game worked when I had 16.10, 17.04, and 17.10 (real fun but hard as heck to 'win'...), but after upgrading to 18.04LTS it appears to load when you click it, but never does and sometimes will instead display that it had a problem closing and wants to report the bug (so I let it). The website for the game has no way to contact it's owner/creator, so I just hope it somehow just begins to work again... Anyone got any ideas other than uninstall and find another similar arcade game? (and can you recommend one?)
As said, I'd like to change default terminal. I've set ctr+alt+t shortcut and it starts xfce4 terminal. But it's bothersome sometimes. There's an option open in terminal/open terminal when u click rmb, but it still opens previous terminal, even though I've set xfce4 as default using this:
sudo update-alternatives --config x-terminal-emulator
Does anyone know how to change it?
I am trying to setup a wireless USB adapter on my machine and I am currently lost. I believe I installed the driver correctly based on my lsusb info below:
BUS 001 Device 002: ID 0bda:818b Realtek Semiconductor Corp.
However when I run ifconfig I do not see my wireless interface.
But for some reason when I run ifconfig -a I am able to see the new interface but it appears with Link encap:Ethernet:
ifconfig -a output:
In addition when I run lshw -C network it claims USB:0 Disabled.
lshw output:
I am relatively new to Ubuntu but I think I need to enable the USB in order for my adapter to work. How can I do this? Is their an alternative solution?
Lastly my wireless extention appears when I run iwconfig. I would post a screenshot but my reputation is not high enough for more than 2 links.
I'm trying to install drivers in Ubuntu 12.04 for my ATI Mobility Radeon X1400 and haven't worked out how to yet. I'm not new to Ubuntu but now that I want to play TF2 on it I need Catalyst. Can someone please tell me how to do this, thanks.
