I recently installed Ubuntu 25.10 on a Lenovo X1 Yoga (4th gen) I got on eBay. It has been working very well lately, however a question about battery charging behavior has popped up.

This morning, I plugged my charger into the laptop (it is a USB-C connection) this morning and noticed that while the amber LED was lit indicating that the laptop recognizes that the AC is connected, Ubuntu does not show that the battery is charging. A quick look into battery statistics shows battery in state of "Waiting to charge"

I read a post elsewhere on this forum from 5 years ago suggesting that this is normal behavior, but it was not marked as solved, so I just want to confirm, is this expected behavior? I assume that once the battery discharges to a certain percentage, the battery will be allowed to charge.

It occurs to me that this this first time I plugged it in without it being below 20% or so, so this may very well be the case. I just wanted confirm before I unplug it and allow it to discharge. Right now it is holding 78% while plugged in.

Brave AI gives link: https://cdimage.ubuntu.com/releases/22.04/release/ubuntu-22.04-desktop-arm64.iso, it only give NOT FOUND, tried many mirrored site, same, NOT FOUND.Tried with private window, clearing cache etc, always NOT FOUND.

Want to only use a virtual machine in Ubuntu for my arm laptop because windows 11 arm does not have any working virtual machine app for ARM.

I do have a dual boot Lenovo AMD laptop that MUMU Player works well in windows 11. I need and want my other Traveling Lenovo ARM snapdragon laptop windows 11 to have working virtual machine for ARM, want to setup dual boot. That is why I need to download ubuntu 22.04 LTS ARM for only android apps.

I tried ubuntu 24.04 LTS 3 clean installs with ubuntu updates but bottom line, Waydroid not binding correctly, AI said 22.04 will bind, but problems with 24.04 binding.

Please post a WORKING LINK for desktop ubuntu 22.04 LTS ARM laptop, not server. I then should be all set.

thanks

Firefox is my default browser. If I click on a link in an app like GNOME Terminal, the link opens in a new tab in an existing Firefox window, and the window comes to the front (in front of / on top of all other windows). But the typing focus remains in the (now underneath) terminal window! Is there any way to prevent or tweak this behavior? I'd like one of these (preference for #2):

1. Click link in terminal, Firefox doesn't come to the front so it's obvious I'm still in the terminal. Typing focus remains in the terminal.

2. Click link in terminal, Firefox comes to the front, typing focus shifts to Firefox.

Other notes/thoughts:

• I'm using 64-bit Ubuntu 24.04.3 LTS desktop with the default window manager (wayland + mutter, I guess?). Firefox is from a snap and is at version 145.0.2.

• My original "new tab" scenario/repro requires that Firefox is already open. If clicking a link starts Firefox, or if I run firefox --new-window https://example.com in the terminal, that new Firefox window does get typing focus after appearing (in front of all other windows).

• If I make Chromium the default browser, it does get typing focus when it opens a link from the terminal, either when it does so in a new tab or new window.

• Maybe this has something to do with focus stealing prevention?

For a few weeks I have been getting timeouts when trying to update snaps from snapcraft.io. So I have been googling, and one of the fixes was to remove all snaps, remove snapd, then reinstall snapd and the various snaps. I am in the process of trying this and started getting this error: cannot refresh, install, or download: soft-expired device authorization needs refresh

If anyone can tell me what I need to do to restore the snapd system to operability, it would be appreciated.

I'm new to Linux and Ubuntu 24.04. I was trying to install Firefox developer on my system. I downloaded firefox-146.0b9.tar.xz file and extracted and moved it to /usr/local/bin directory. When I tried to pin the app, I found out I should copy it .Desktop file to my /usr/local/share div and the Firefox subdirectory doesn't have any. Desktop file...

And I'm stumped. In the Firefox doc it didn't say how to create a.desktop file. What should I do?

Right-clicking on the desktop usually brings up the option to edit your desktop settings.
I was messing around with it and set left-click to open the app menu.
I went to remove this left-click function and accidentally deleted the right-click instead. I can no longer find the Desktop Settings window or how to open it.
User Goncalo Andrade also had this problem but never solved it:
Can't right click in desktop anymore

In October, I migrated from Win 10 to Ubuntu, rather than suffer Win 11. It has been going well, but I am getting this problem when Ubuntu Discover tries to do a "firmware update":

Ubuntu Discover update "failed to write-firmware: failed to write (null): failed to write data to efivarsfs: Error writing to file descriptor: Invalid argument"

Even more irritating, I dismiss the error message and it pops right back. The Discover updater captures the cursor too quickly to close the program, leaving me stuck. The cursor/mouse is captured by Discover, leaving me unable to do anything other than close the error message box, which pops right back endlessly.

The first time this happened, I tried the reset button on the PC, but that had the bad side effect of leaving a couple drives with "missing mount points", which I had to remove from the PC and put in my old Win 10 pc and run partition manager to scan them for errors, then back in to my main PC and all was happy again. Yes, I know there is a way to do this in Ubuntu, but I felt too newbie to try it and risk losing important data. And yes, I do have a back up, but some recent things might have been lost.

The second time this happened, just this morning, I was able to click on the Discover icon on the left of the Task Manager bar and manage to quit Discover after several tries. A quick right click on the icon and then a typed Q to quit, if done quickly enough was able to do the job.

Thank you for any help

I want to reinstall Chromium for reasons I no longer recall. Two weeks ago, I tried and it completely broke, only outputting error: snap "chromium" has "remove-snap" change in progress. I have not been able to resolve since. I am running Ubuntu 24.04.

Short of reinstalling the entire operating system from scratch for one single application - which I already had to do once because for some incomprehensible reason, uninstalling Thunderbird bricks the entire system upon the next boot - is there a way to fix this?

This error is reproduced by:

sudo snap remove chromium or

sudo snap remove --purge chromium

I have tried:

• Turning it [the PC] off and turning it on again, at least 20 times incidentally
• snap abort ID (which does absolutely nothing)
• snap enable chromium
• snap refresh && snap abort ID
• Uninstalling through the Ubuntu Software window
• sudo rm /var/cache/fontconfig/*
• rm ~/.cache/fontconfig/*
• sudo fc-cache -r -v
• rm -rf ~/snap/chromium/common/.cache/fontconfig/
• setting system clock 1 year ahead
• sudo snap revert chromium && sudo snap refresh chromium && sudo snap remove chromium

Here is the feedback I get from various commands, much of it contradictory:

• snap changes outputs 11 Undo 14 days ago, at 12:41 CST - Remove "chromium" snap
• snap list outputs chromium 142.0.7444.162 3307 latest/stable canonical✓ disabled
• chromium-browser outputs Command '/usr/bin/chromium-browser' requires the chromium snap to be installed. Please install it with: snap install chromium
• snap install chromium outputs snap "chromium" is already installed, see 'snap help refresh'
• sudo snap revert chromium outputs error: cannot revert "chromium": no revision to revert to
• sudo snap refresh chromium outputs error: cannot refresh "chromium": refreshing disabled snap "chromium" not supported

Lastly, snap list 11 outputs:

There are lots of questions around this, and lots of solutions, but not much explanation. I have tried a few things, but so far do not have a working wifi connection on my Macbook Air 7,2 A1466. It's a fresh install of Kubuntu 25.10, if it helps.

lspci shows I have a Broadcom BCM4360, so I have (whilst connected to my phone via bluetooth) done the following:

sudo apt install firmware-b43-installer
sudo modprobe -rv b43
sudo modprobe -v b43
sudo reboot now

But I still get no sign of wifi being available.

The entry for "kernel driver in use" for the Broadcom card says bcma-pci-bridge. Assuming this should be the b43 firmware instead, how do I change it?

I don't really understand any of this (hence asking again, as the other posts are confusing and I don't want to start randomly throwing terminal commands at a problem I don't understand) so any help would be appreciated.

Unfortunately, I recently broke my installation of NVIDIA drivers and so I had been purging them for reinstallation. However, after purging, running sudo ubuntu-drivers autoinstall raises an error about missing dependencies.

After installing the listed dependency, the same error still shows up.

More explicitly, the process for purging and reinstalling nvidia packages was as follows:

sudo apt remove --purge nvidia-* cuda-* libnvidia-*
sudo apt autoremove
sudo apt autoclean
reboot
sudo ubuntu-drivers autoinstall

The final step yielded the error

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 linux-modules-nvidia-580-open-6.8.0-88-generic : Depends: nvidia-kernel-common-580 (<= 580.95.05-1) but 580.105.08-0ubuntu1 is to be installed
E: Unable to correct problems, you have held broken packages.

I therefore followed the recommendation and ran update-drivers again

sudo apt-get install nvidia-kernel-common-580
sudo ubuntu-drivers autoinstall

But this yielded the same error, despite having installed the package.

What can I do to fix this? I would also love to take this as a learning moment and would appreciate explanations as to why this is occurring.

I need to permanently map a Windows drive on 2 Ubuntu 22.04 machines with the same setup and configuration.

The strange thing is one is working, but the other one just doesn't.

//serverip/path /home/ubuntu/pictures ctfs credentials=/home/ubuntu/.smbcredentials,uid=1000,gid=1000,x-systemd,automount 0 0 UUID=F47A-11C2 /boot/efi vfat defaults 0 1

When I try to mount it after reboot, the mapped drive will show Unable to access location mount.cifs: Permission denied. I have tried to add _Netdev to it, but it's still not able to permanently map the drive.

I am trying to create a script that listens to the desktop notifications dbus and print the sender and message to the command line.... the final goal is to run a specific function when I get a specific notification.

I tried using dbus-monitor --session which prints stuff out when I get a notification, but I don't see the actual notification. I had Gemini AI help me write some python code, this code runs, but nothing happens when I get a notification.

It seems like this should be a simple task.... I would rather use a bash script if I could, but python would be fine too.

I did find this post which had a python script that I had to be update to work with py3. This script runs but nothing happens when I get a notification or send one via notify-send

from gi.repository import Gtk

    # the NameAcquired message comes through before match string gets applied
    if message.get_member() != "Notify":
        return
    args = message.get_args_list()
    # args are
    # (app_name, notification_id, icon, summary, body, actions, hints, timeout)
    print("Notification from app '%s'" % args[0])
    print("Summary: %s" % args[3])
    print("Body: %s", args[4])

With attempt to change my password with command passwd in terminal,

passwd Passworts für linux wird geändert. Geben Sie das aktuelle Passwort ein:

I typed in old password, then query comes for new password.

Geben Sie das neue Passwort ein :

I typed over 200 chars in new password and enter. Then passwd claims that my password would be too small "according to dictionary" ?!

As far as I know, Linux and Ubuntu allows passwords with up to 512 chars. What is up with command passwd ? In Ubuntu 24.04 ... after recent update one week before ?

This happened at Ubuntu already between version 12.04 and 18.04 ?

I wonder if I can set the timeout to the boot time LUKS unlocking and let the PC shut down on timeout.

In other words, I want the PC to shut down automatically when I leave it without typing the password 1min.

This is particularly useful for laptops. Some computers turn on by shock or some other event. Without a timeout, the PC will wait for the password until the battery is fully discharged.

Screenshot of the disk unlocking screen:

In /etc/default/keyboard, I have XKBOPTIONS="ctrl:nocaps" set. Sometimes, I decide that I need my caps lock. In other words, I want to run something in my terminal to undo this setting.

I've tried setxkbmap -option caps:capslock, but that simply does nothing.

Hoping someone out there might be able to help point me in the right direction of resolving this. Somewhere over the last month or so, hardware acceleration on my emulators has broken for Android development. I'm running Kubuntu 24.04, on a Lenovo with an Intel ARC GPU on die (following Intel's instructions on figuring out what hardware I have here, I have a 7D55 PCI ID, so it's an Intel® Arc™ Graphics Xe-LPG Meteor Lake GPU, supported in kernel since 6.7. uname -a says I'm on Ubuntu's 6.14.0-29 generic kernel. So I guess from that perspective, I'm doing OK so far.

But when I run the emulator with -gpu host flag, I get the following output and it never starts:

StackOverflow had me install this driver from Intel's PPA, but no change.

I've also tried disabling Vulkan w/ the emulator flag -feature -Vulkan which changed the stacktrace slightly to the following, but ultimately, looks like a crash in the same spot.

Ultimately, it seems I have a problem in Mesa, but I just don't know enough about the graphics stack to proceed further. Any help appreciated!

I have 4 other monitors hooked up in addition to the built-in screen, using all 3 dock outputs and 1 USB adapter, and scripts to control which of the 5 are used at a given moment. A set of keyboard shortcuts triggers those scripts, so I can "call" my desktop to whichever station I'm at, and work from there.

A representative sample of those scripts:

# Touchscreen on correct monitor only

xinput map-to-output "Wacom ISDv4 4001 Finger touch" eDP-1

I think you get the idea.

• eDP-1 is the built-in screen.
• DP-1-0 and DP-1-2 are both DVI and sometimes used to extend the built-in screen, but not always.
• DVI-I-2-1 is a USB3 to HDMI adapter that has a short HDMI to DVI cord on it, at the end of a long USB3 extension and then a powered hub.
• VGA-1 is an old LCD monitor with VGA input only and a dead CCFL backlight, so I put some LED strips in it with a custom controller, that is commanded by a set of scripts that are called from here.

A sample of the other scripts:

audio-desk.sh:

#!/bin/bash



# Audio Defaults (from pactl get-default-[sink|source])

pactl set-default-sink    "alsa_output.pci-0000_00_1b.0.analog-stereo"
pactl set-default-source   "alsa_input.pci-0000_00_1b.0.analog-stereo"

backlight_2_off.sh:

#!/bin/bash



SCRIPT_DIR=`dirname $0`



#basic setup

if [ -e /dev/ttyUSB0 ]
then
    stty -F /dev/ttyUSB0 1200
fi




#backlight off (blank command, equal to #000000FF!)

if [ -e /dev/ttyUSB0 ]
then
    echo "#!" > /dev/ttyUSB0
fi

(Setup and command are actually their own scripts that I consolidated into here for easier reading. That's all they do.)

The Problem:

It periodically switches to the built-in screen by itself (what I call "Desk 1"), and then back to what I've told it. No user input during that entire time.

• If I'm using another station, that monitor goes blank (no signal), and if I look over at the built-in screen, I see the image over there that is supposed to be on my selected station. Then a few seconds later with no prompting, it switches back.
• If it's supposed to be blank (no screens active), it turns the built-in screen on for a few seconds and back off again.
• If I'm using one of the extended modes (Desk 2 or 3) that includes the built-in screen, it disables the extensions and reconfigures the geometry to just the single built-in display, and then re-extends and reconfigures the geometry again. Again, this is all with no prompting.
• If I'm already using just the one built-in screen (Desk 1), I wouldn't be surprised if it still does this, but it makes no difference and so I can't see it.

Troubleshooting:

Mirroring the built-in screen to an external one (2 screens with the exact same image, one of which is built-in), is rock-solid on both screens. A 3-hour movie and a 1-hour presentation were both flawless like that.

Also, it appears that "turning the screen off" by the Power Management system instead of disabling all of them as above, does not glitch either, regardless of which monitors are enabled:

That's only a partial solution though, because it doesn't do anything about a configuration that does not include the built-in screen.

Adding some trap code shows that the scripts are (probably) not running for the glitch:
date >> debug.log
It appears that they only run when I tell them to, with the keyboard shortcuts. So the system still knows internally what it's supposed to be, but it "hiccups" occasionally, always to the built-in screen by itself, and then fixes itself.

Now the question:

Why does it do that? And how can I prevent the hiccup?

I'm trying to install "yfinance" on Ubuntu 24.04. Everyone on the web says to use "pip" to install, but Ubuntu gives a long message saying that's not a good idea, to use the equivalent of "apt install python3-xyz" instead.

That much is ok, but running

sudo apt-get -y install python3-yfinance

can't find anything

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package python3-yfinance

How do I point to the right repo for this?

I recently added an old monitor to my setup that I connected to my PC using a VGA cable, while the other with an HDMI cable, using the multimonitor option, because one monitor is connected to the motherboard, while the other is connected to the video card. When I use flameshot it only takes a screenshot of one monitor, the one connected to the motherboard, but I want to take a screenshot on the other monitor. I tried checking the options but it doesn't let me change the monitor I can take a screenshot on. Is there any other solution, other than moving the window I need to take a screenshot on the other monitor? I use Kubuntu.

How can I disable the insert key on Ubuntu 22.04 in Wayland?

In X11, it was simple:

# Figure out what keycode is mapped to insert key.
xmodmap -pke | grep -i insert

# Disable it.
echo "keycode 90 =" >> ~/.Xmodmap

Is there no similar remapping functionality in Wayland?

Newbie here.

I've got an external hard drive (EXT.4 format) that I'm trying to use as a destination for LuckyBackup.

It seems that I don't have permissions to use the hard drive.

I've tried to change permissions through 'Properties/Permissions' where it defines the user as 'root' and the group as 'root.' It also says that I am not the owner so I can't change the permissions.

I've also tried this solution: https://forum.manjaro.org/t/mount-a-external-hard-drive-with-execute-permissions/39767/4 but my 'directory' could not be recognized (even though the drive was mounted).

Does anyone have any advice?

Thanks!

Recently installed Ubuntu 22.04 (my first foray into Linux).

One thing I got involved with from the get-go was adding custom entries to the context menus. Basically, using python3-nautilus, I managed to add menu items to context menus of folders (via get_background_items) and files (via get_file_items). For files, I could even add the custom entries for all files or specific file types by filtering mime-types. So far so good.

What I haven't been able to figure out was how to add items to the Gnome Desktop context menu. I presume the Gnome Desktop is closely tied to the Nautilus file manager but I have no idea how to go about customizing the Desktop context menu using python-nautilus.

Any help please?

EDIT: For example, the right click context menu for folder backgrounds (empty space in a folder window) now has two additional custom items, Calculator and Text Editor, that allow me to launch those apps from within the context menu. I would like to achieve the same thing (or at least something in the same vein) for the desktop right click menu.

To further explain how the above customization was achieved, first, I installed python3-nautilus, and then I created a Python script (well, I actually created several scripts for different functionality) in the Home/.local/share/nautilus-python/extensions folder with the following code:

import os

from gi.repository import Nautilus, GObject

class BackgroundItemMenuProvider(GObject.GObject, Nautilus.MenuProvider):
    def __init__(self):
        pass

    def menu_activate_cb_gcalc(self, menu, file):
         os.system("gnome-calculator & pid=$!")
         
    def menu_activate_cb_gedit(self, menu, file):
         os.system("gnome-text-editor --new-window & pid=$!")

    def get_background_items(self, window, file):
        item_gcalc = Nautilus.MenuItem(name='BackgroundItemMenuProvider::Calculator', 
                                       label='Calculator', 
                                       tip='',
                                       icon='')
        item_gcalc.connect('activate', self.menu_activate_cb_gcalc, file)
        item_gedit = Nautilus.MenuItem(name='BackgroundItemMenuProvider::TextEditor', 
                                       label='Text Editor', 
                                       tip='',
                                       icon='')
        item_gedit.connect('activate', self.menu_activate_cb_gedit, file)
        return item_gcalc,item_gedit,

I have laptop Acer spin 5 "Spin SP513-54N" and had ubutnu 21.10 installed on it. At first, the touch pad and touch screen were not working so I followed the instructions in this page and it fixed it: https://sciactive.com/2020/12/04/how-to-install-ubuntu-on-acer-spin-5-sp513-54n-for-the-perfect-linux-2-in-1/

sudo gedit /etc/default/grub
Add pci=nocrs to the end of the options for GRUB_CMDLINE_LINUX_DEFAULT. It should look something like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nocrs"
sudo update-grub

Later when I upgraded to ubuntu 22.04, touch pad and touch screen stopped working again When ubuntu 22.04 starts up before applying GRUB fix, I get this error:

Ubuntu starts fine but the touch is not working. But when I apply the fix, ubuntu 22.04 fails to start with this error:

I tried every fix I could possible find online but nothing works. plz help me with this issue as the computer is not usable without touch pad

Like on Macintosh (or even Windows, I suppose), iTunes will immediately recognize and use wireless streaming to play music via an Airplay device. I want my Ubuntu to do that. Simultaneous output, separate volume controls, play/pause, etc.

(BTW iTunes works fine, even the compact version from my iPad.)

I installed paprefs which gave Gnome a GUI, when installed with pulseaudio-module-raop, it adds a sound device, as advertised. But when I load my audio-player (tried many...) and play music, no sound is emitted when I select that device, although it will play fine on using the desktop-speakers - when selected. It never asked for the password. (I suspect this is why it doesn't work).

(I have tried many suggestions on ~oogle and all have failed.) Also I've tried many solutions (like airplay.jar, open-airplay, etc.) and they don't work with 18.04 and most are no longer maintained.

Hopefully there just an audio-player (like iTunes) for Ubuntu 18.04 that just plays to desktop-speakers as well as my home theatre.

Otherwise I can attempt to build from the code in say, open-airplay...

Ideas / suggestions... Has any Ubuntu users got a similar situation working - if so, how?

I am running out of ideas (and sources of ideas) on this one. I am getting a file-path from Audacious, and trying to get album art from the directory referenced. The info provided is correct, and works in terminal.

Things I have tried:

1. Redirected variable to a file, and looked with hexedit for odd characters.

2. Checked script for odd characters the same way.

3. Executed the script with /bin/bash directly.

4. Made a new script with only the non-functional code.

5. Because the path returned is relative [~/Music/Eagles/Desperado] have tried it as [/home/freebird/Music/Eagles/Desperado].

6. Because [Music] is a soft link to another drive have tried it as [/mnt/data/Music/Eagles/Desperado]

7. Have been using the Eagles because I didn't want to deal with [~/Music/Alice Cooper/School's Out] until I had the simpler case working!

8. IT does not have any CR's or other extraneous characters from editing on Windows or elsewhere - haven't used Windows for anything but Freecell and Spider Solitaire since 2007.

9. Nothing so far can resolve the resulting path into usability from inside the script, ALL work from the terminal (including cd).

Here is the actual error message from a recent try:

freebird@nest:~$ ~/check.sh
/home/freebird/check.sh: line 8: cd: ~/Music/Eagles/Desperado: No such file or directory

Any further suspects for me?

Here is the check script for testing:

#!/bin/bash
file_path=`audtool --current-song-tuple-data file-path`
echo > test2 ${file_path}
#${file-path}="/mnt/data/""${file_path:2}"
echo > testpath ${file_path}
cd "${file_path}"
#cd -P "${file-path}"
pwd
exit 1
if [[ ! -e "folder.jpg" ]];   # if no art work found
    then
    cp ~/Work/headphone.png /tmp/cover.png # put in placeholder
    echo "Placeholder"
 else
    convert "${file_path}""/folder.jpg" -resize 120x120 /tmp/cover.png # ready for showing
    echo "found cover"
 fi

It contains various 'test' additions still, the equivalent of scattered printf() to see what's going on :)

new version of testing script:

#!/bin/bash
file_path=`audtool --current-song-tuple-data file-path`
file_path=$(eval echo $file_path)
echo > test2 ${file_path}
${file-path}="$HOME"${file_path:1}
echo > testpath ${file_path}
cd ${file-path}
#cd -P "${file-path}"
pwd
exit 1
if [[ ! -e "folder.jpg" ]];   # if no art work found
    then
    cp ~/Work/headphone.png /tmp/cover.png # put in placeholder
    echo "Placeholder"
 else
    convert "${file_path}""/folder.jpg" -resize 120x120 /tmp/cover.png # ready for showing
    echo "found cover"
 fi

It is normal for Ubuntu installation to remain at the "Detecting File Systems" stage for long? I followed all the steps as recommended, I have created the partition "/" and "Home", I am now waiting on the installation window while I get the message "detecting file systems". It's been about two hours.

Installing Ubuntu 14 from a DVD.

I am running Ubuntu server 12.04 with Apache2.

My port 80 is not reachable and closed. Any idea how can I open it so I can access to my web admin?

I noticed that port 80 is reachable under LAN, but its not able to reach outside of LAN even I had done port forwarding.

What should I do?

Thanks.

Hi. I've got a working Ubuntu 12.04 server, which is going to serve as media server. I've added two disks of size 3TB to put my data on, and I wish to combine these as one 6TB logical volume which I could mount under /media.

So far, I have created one partition on each disks with fdisk and formatted them to ext3. But now I am stuck on how to continue. Do I use Mdadm to create a Jbod array? Or do I use LVM to make a logical volume of these two disks? I can't seem to find the documentation I need, it's mostly about extending existing volumes or installing a fresh system which I don't need.

My OS is on /dev/sdc1 (it's a USB thumb-drive), and the two newly created partitions are on /dev/sda1 and /dev/sdb1.

Hope you can give me some directions.

I'm looking for a tool that will take diff / debdiff output (and more specifically, the output of this script) and display the result of the comparison in a highly readable, graphical way. Any pointers would be appreciated.

Ideally, it would be the GTK+, FOSS equivalent of MDR.

Meld, Diffuse and similar software are not fit for this purpose, since they're intended to work standalone, and don't take input from stdin.
