Well my old laptop is a Dell Latitude E6510

Current OS is Linux 6.8.0-94-generic

Ubuntu 22.04.5 LTS

Yesterday Feb 14 there was a small system upgrade. And after the upgrade the laptop will not charge the battery.

The battery is only 2 months old. With the power supply plugged into the laptop the percentage of the battery state is unchanged (52%).

I tried the Dell tricks but nothing.

Has anyone seen this ?

I have this 256GB drive, that is divided into 3 partitions. Here is the lsblk results.

The GUI Disk utility shows this 107GB “Block device” named ubuntu--vg-ubuntu--lv and mounted at Filesystem Root. What and where is this device coming from? Was it created when the OS was installed? From the lsblk command I can only assume this is from the nvme0n1p3 partition. Where is the (roughly) missing (235-100) 135GB?

For giggles, here’s the df output

Settings shows "dummy output." The windows partition on the XPS has sound.

Hardinfo2 says the audio is "null" and the vendor is "unknown"

I assume Canonical is working on this with Dell but hope that someone here has a workaround.

Deja Dup (42.9) on stock Ubuntu 22.04.5 LTS. When I try to back up, Deja asks for the password, goes back (presumably) to backing up then asks for the password again. After doing some sleuthing online I've uninstalled Deja Dup and Duplicity. I renamed the backup destination on the external hard drive. I shut down the computer, let it sit a few minutes, then rebooted and installed Deja Dup. I renamed the backup location to match the HDD and renamed folder. I clicked 'start backup' and was prompted to create a new password. I did that and started backup. I get prompted for a password, I enter, the backup starts... and the same thing happens. It's an endless loop: Enter password, backup starts, prompted for password, enter it... rinse and repeat.

I am new in X11 so is this code Ok?

Effect is just turn all screens black.

#include <X11/Xlib.h>
#include <stdlib.h>

int main() {
    Display *dpy = XOpenDisplay(NULL);
    if (!dpy) return 1;

    XSetWindowAttributes attr;
    attr.override_redirect = True;
    attr.background_pixel = BlackPixel(dpy, scr);
    // Optimization 2: Only listen for the first movement (PointerMotionHintMask)
    // or key presses to reduce event traffic.
    attr.event_mask = KeyPressMask | ButtonPressMask | PointerMotionMask;

    Window win = XCreateWindow(dpy, root, 0, 0, 
                               DisplayWidth(dpy, scr), DisplayHeight(dpy, scr),

    Pixmap bm = XCreatePixmap(dpy, win, 1, 1, 1);
    XColor black = {0};
    Cursor inv = XCreatePixmapCursor(dpy, bm, bm, &black, &black, 0, 0);
    XDefineCursor(dpy, win, inv);

    XMapRaised(dpy, win);
    
    // Optimization 4: Grab both Keyboard AND Pointer
    // This ensures no other app steals the "focus" or mouse clicks
    XGrabKeyboard(dpy, win, False, GrabModeAsync, GrabModeAsync, CurrentTime);
    XGrabPointer(dpy, win, False, ButtonPressMask | PointerMotionMask, 
                 GrabModeAsync, GrabModeAsync, None, inv, CurrentTime);

    XEvent ev;
    while (1) {
        XNextEvent(dpy, &ev);
        // Any interaction exits
        if (ev.type == KeyPress || ev.type == MotionNotify || ev.type == ButtonPress)

I'm currently doing a course on Cisco called Network Devices and Initial Configuration. In one of the labs, it's asking me to Install Linux in a Virtual Machine and Explore the GUI. I'm able to get to the page below without issues:

However, after following the instructions below, Ubuntu does not restart like it's supposed to:

Instead, it just freezes at this page:

I'm using the latest version of VirtualBox, 7.6.2a and have Windows 11 as an OS. Please advise.

it is my first post/ask here. I tried to search a lot as different approaches from everywhere but so far no luck :-( Here is my problem. I have a Mini PC called Beelink Mini S12 that I use as Media Server. I has Ubuntu Server 24.04.4 LTS with Kernel 6.17.0-14-generic on it. I did all setups like 6 months ago and after that never had to touch it again, it was 100% working well and stable until yesterday when I was not able to connect into it anymore. Today, after some investigation I found that it had lost the Ethernet connect and as I was using it connected into my router via cable I lost the access. Okay, so I re-enable the Wifi temporally to be able to work on it until I find and fix the issue with Ethernet but after try everything Im still no luck and not ethernet connection back :-(

Here is some prints from my setup/ethernt: Ubuntu/Kernel

My networks interfaces: interfaces

Driver updated to use r8168-dkms: driver

I have no idea what is going as it was working before and I didnt update anything (at least not manually by myself)

So i am currently dual booting Zorin OS on a HDD. Everything is Fine but i cannot get to install drivers. I have a Nvidia Quadro 600 Which is a legacy driver. I tried doing these things :

sudo apt update and sudo apt install nvidia-390 but when i try that it outputs this:

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package nvidia-390 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

I am currently running a dual boot Ubuntu 24.04 and Windows 11 setup via a live USB 3.1 drive. This setup works fine and has no issues. I had asked earlier on the best way to clone/ back up my set up and got helpful answers on ways to do it.

The GParted copy and paste method, and a Clonezilla method that involved restoring GRUB. The GParted method resulted in my new clone of Ubuntu booting fine, but Windows 11 would give me a PC needs to be repaired error and would boot loop if I tried any repair options, even with a live installation of Windows 11.

Next I tried doing a part-part clone of each partition of Windows, followed by the Vfat partition to see if this would fix it, and had no luck. Later I tried a basic disk-disk clone via Clonezilla and now Windows and Ubuntu boot fine. This surprised me as the user from this post mentioned this didn't work for them and they had to jump through hoops as well as reconfigure grub each time they did it. I did make sure to boot into a live installation of Ubuntu and removed my HDD from my computer to use GParted.

How can I use GParted so that it does not ruin my dual boot USB?

I have followed the posted method very closely, and I do not believe this to be a result of misreading instructions. I'd prefer this method, so that I can back up a single partition as opposed to cloning my entire hard drive each time a major update gets released.

it complains

Every single time I open up Ubuntu, the same thing happens. No sound. If I reboot, I get sound for a while then silence. I've installed 24.04 only a day ago and this just keeps happening. Also if I open settings, I get a little bit of sound before more silence. (on a EZ book S7 Hi) Edit: If I put a headphone jack in, even when there's no headphones attached, sound plays.

Trying to use this:

A third option is to do a re-install of the operating system but do not format and just 'overwrite' your existing installation. Boot to the install media and go through the install process as usual.When you get to the partitioner to allocate drive space, depending on the version you are installing check the box marked 'Manually select partitions' or 'Something else' and click forward. Use the SAME user name and password as the existing account when setting up again. Find your existing installation and you must UNCHECK all the 'format' boxes and mount the partitions in the same place they are now. As long as no 'format' boxes are checked, no data will be lost in your home folder and the system files will be overwritten with the originals. You should then complete all system updates again.

but I get to here using Ubuntu 24.04.3 Desktop AMD64 iso on bootable USB:

and can go no further using these instructions... my Ubuntu location to re-install to is sda5, which I can mount at /, but it won't let me uncheck the format box - so probably the wrong mount point to do this - other options are:

/boot

/home

/tmp

but are not where it needs to be re-installed to.

Reading on below, it appears format is forced due to Ubuntu not fixing their installer glitch and instead resorting to this inconvenience...

Well, except for the ‘nautilus, and nautilus type window pop-up corruption”, my Ubuntu Desktop 24.04.3LTS AMD64 system runs perfect - can still manipulate files via terminal and bypass nautilus, just click on the download link in my email (which just defaults to my Downloads folder, instead of save as which tries to pop-up the nautilus type window that crashes)… and the more complex work can be done using my Windows 10 laptop that works really great :-P

Why, when I am only updating Zen Browser with KDE Discover on Kubuntu does it never asks for my password. Everything else seems to require a password and I am concerned I have done something wrong.

Thanks.

In WSL2, writing to /dev/console goes nowhere apparent. What happens to things written there? This question is generally to clarify the role of virtual consoles in WSL2 and hvc0.

A 2010 post with no responses asks

I would like to get some information regrading the hvc0 terminal. A search on the web hasn't came with useful stuff.

And it is thinly discussed in any StackExchange questions; one of the only is https://unix.stackexchange.com/questions/10857/what-is-hvc0-appearing-in-who-list

In Ubuntu running on Virtualbox,

virtualbox$ cat /proc/consoles
tty0                 -WU (EC  p  )    4:3
virtualbox$ echo hello | sudo dd of=/dev/console status=none
hello                                                                                                                                           virtualbox$ echo hello | sudo dd of=/dev/tty0 status=none
hello
virtualbox$ tty
/dev/tty3
virtualbox$ fgconsole
3
virtualbox$ cat /sys/class/tty/tty0/active
tty3                                                                                                                                               virtualbox$ echo hello | dd of=/dev/tty3 status=none
hello
virtualbox$ sudo cat /dev/vcs3 > out

The above session typescript is made with the last command in it.

In WSL2, writing to /dev/console goes nowhere apparent. If the answer is to run strace, like

echo hello | sudo strace dd of=/dev/console

where is the "interesting" part of the output, which is a bunch of UTF stuff, mmap, fstat, open and close.

There is no /dev/tty0 or /dev/vcs0, but instead /dev/hvc0.

wsl$ cat /proc/consoles
hvc0                 -W- (EC p  )  229:0

In WSL, despite not being able to access virtual consoles like in usual Linux, we can write and read to them:

wsl$ echo hello | sudo dd of=/dev/tty1 status=none
wsl$ sudo cat /dev/vcs1

Ubuntu 24.04.3 LTS laptop tty1                                                                                                                                  laptop login: hello

The following seems to mean that tty1 is "populated" with a login screen (by systemd getty?), that is we can see the login by reading /dev/vcs1 but we see nothing reading /dev/vcs2.

wsl$ cat /sys/class/tty/tty0/active
tty1
wsl$ fgconsole
Couldn't get a file descriptor referring to the console.

However we can indeed write to /dev/tty2 and then read from /dev/vcs2:

wsl$ echo hello | sudo dd of=/dev/tty2 status=none
wsl$ sudo cat /dev/vcs2
hello

After a fresh installation of Ubuntu 24.04 on an Acer Spin laptop no sound is produced from either speakers or headphones. In the settings -> sound -> output, the bar moves when the test button is pressed. The output device - “Ice Lake-LP Smart Sound Technology Audio Controller” – can choose between Speakers or Headphones.

I installed pavucontrol. Pavucontrol shows both speakers and headphones: The bar in Volume Control moves when when I “Test Speakers”, but there is no sound. It is not muted in this setting.

Under Windows, speakers and headphones worked fine. What can I do to get the speakers and headphones working in Ubuntu?

I am using a laptop equipped with an NVIDIA GeForce RTX 3050 GPU, running Ubuntu 24.04.3 LTS. Recently, I have been experiencing several display issues: the screen frequently flickers, sometimes turns off by itself, and overall the graphics performance feels unstable.

Here are my system details for reference: my device is a laptop with NVIDIA GeForce RTX 3050, Ubuntu version is 24.04.3 LTS, and the NVIDIA driver version installed is 570.195.03.

I have already tried common troubleshooting steps, such as switching between different prime-select modes (Intel, NVIDIA, and on-demand) and disabling Wayland, but the problems persists. I suspect that the issues may be related to GPU driver compatibility with this Ubuntu version or to power management settings on the laptop.

Could you please advise on the most stable configuration or recommend any workaround that can prevent the screen flickering and unexpected shutdowns?

I’m having trouble getting my MediaTek MT7902 WiFi card to work on Ubuntu 24.04 the last version of Ubuntu with kernel 6.8.0-51. The card works fine on Windows, but on Ubuntu, no networks are detected.

Details:

1. The card shows up in lspci:

00:02.0 Network controller [0280]: MEDIATEK Corp. Device [14c3:7902]

2. ip link output:

2: enx022376651f09: <BROADCAST,MULTICAST,UP> mtu 65536 qdisc fq_codel state UNKNOWN mode DEFAULT group default qlen 1000

3. Firmware (linux-firmware) is up to date.

4. I loaded the mt76 driver (modprobe mt76), but it doesn’t seem to work.

5. dmesg gives:

read kernel buffer failed: Operation not permitted

What I’ve tried:

• Updated linux-firmware.
• Loaded the mt76 module.
• Restarted NetworkManager.
• Unblocked WiFi using rfkill unblock all.

Question:

How can I get this WiFi card to work on Ubuntu? Do I need a specific driver, firmware, or kernel version?

Thanks for your help!

This machine is a fresh install, about one week old. The only 20.04 remnants is my home directory. I don't pin packages, or rarely install packages with dpkg -i to prevent dependency hell. I don't think I have broken packages, I think this is what it thinks is an "impossible situation". It may be easier for me to do a reinstall of the OS.

I tried to follow the various instructions for installing libpng12.so which eventually led me to do the use the following command after downloading the deb file:

sudo gdebi  libpng12-0_1.2.54-1ubuntu1.1_amd64.deb

But, unfortunately, the installation of the deb leads to the errors below:

Does anyone know why I get these errors? Thanks a lot.

Every time I start Ubuntu 21.10 it goes into emergency mode. I have already tried to do in fsck.ext4 -y /dev/sdb3 and nothing keeps entering that mode that bothers me.

Linux: clean, 1363248/28057600 files, 68026124/112212224 blocks   
You are in emergency mode. After logging in, type "journalctl -xb" to view  
system logs, "systemctl reboot" to reboot, "systemctl default" or "exit"  
to boot into default mode.  
Press Enter for maintenance.  
(or press Control-D to continue.)  

When attempting to boot Ubuntu 20.04 via PXE, I'm getting the error Unable to find a live file system on the network.

I use the NFS method:

menu label ^Install ubuntu
kernel /images/ubuntu20-04/casper/vmlinuz 
append initrd=/images/ubuntu20-04/casper/initrd nfsroot=192.168.2.1:/nfs_share/ubuntu ro netboot=nfs boot=casper ip=dhcp ---

How can I fix this?

I had initially created a couple of directories in /home, which got filled with the content of previously successful work dirs. Consequently, enabling me to try/test/adapt one, and continue on; moving quickly... I settled on one, left the softlink coupled to the chosen dir, and since have installed all manners of working application/drivers/etc from the "Ux Repository" via Synaptic, to date; including Firefox & Chrome.

Today, I found it necessary to install another valued browser (Chromium), only to end up with error message result indicated below. One can also note that every other install was able to set up, and leave it's config stuff in it's ~/.config dir. Thus, I find it frustrating to note that there does not exist a ~/.config/[cC]hromium[-browser] directory there, as well?

Moreover, Chromium also should not need fail in such a manner, as the dir that it claims to have trouble creating, already exists, and is usable? So, is there an existing modification/code addition that I might be able to apply, to enable proper execution with this described setup; other than creating a "odoncaoaB" user, and su'ing to it in order to make use of Chromium every time hereafter?

As the title above, does anyone know what DORMANT mean in this output command ?

$ ip link show wlan0

3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DORMANT group default qlen 1000
link/ether 00:c0:ca:a8:6c:84 brd ff:ff:ff:ff:ff:ff

The network works fine with this mode as well.

Ubuntu 18.04 is by default creating a random encrypted swap during each boot using dm-crypt/Swap encryption. For me, this is creating a 1gb swap but I cannot find where to increase the size of the swap it creates on each boot. How can we increase the swap size allocated during each boot? I do not want to switch to a static swapfile. There is no /swapfile or partition.

This appears to be a new feature where the swap is dynamically created each time the system boots. How can I increase it?

from /etc/crypttab:

nvme0n1p3_crypt UUID=1e092df8-5c37-4409-8ac8-361402244f69 none luks,discard
cryptswap1 UUID=aba1b825-a77b-4384-a40f-fdc6fdaaced0 /dev/urandom swap,offset=1024,cipher=aes-xts-plain64

from /etc/fstab:

/dev/mapper/cryptswap1 none swap sw 0 0

# swapon -s
Filename                Type        Size    Used    Priority
/dev/dm-3                               partition   1003004 601088  -2

gparted does not show any swap partition. This is the only drive.

In an answer here, it is suggested to do:

sudo swapoff -a  
sudo cryptsetup resize cryptswap1 --size (in sectors)  
sudo mkswap /dev/cryptswap1  
sudo swapon -a  

So I run: cryptsetup resize cryptswap1 --size 7812500. This results in the error: Device /dev/mapper/mint--vg-swap_1 is too small.

So I try: cryptsetup resize /dev/mapper/mint--vg-swap_1 --size 7812500

This does not produce an error but parted --list; fdisk -l shows no change:

Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes


Disk /dev/mapper/cryptswap1: 979.5 MiB, 1027080192 bytes, 2006016 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

and trying to again run cryptsetup resize cryptswap1 --size 7812500 produces Device /dev/mapper/mint--vg-swap_1 is too small.

I have also tried: resize2fs /dev/mapper/mint--vg-swap_1 -s 4G which produced:

resize2fs 1.44.1 (24-Mar-2018)
resize2fs: Device or resource busy while trying to open /dev/mapper/mint--vg-swap_1

I have tried several attempts but without success. AMDGPU-PRO 17.40, 17.50, ROCm, Oibaf PPA, Kernel 4.16 and something more, but nothing makes OpenCL working with the AMD card and clinfo never gives right results.

Can I only wait the next AMDGPU-PRO driver compatible with Ubuntu 18.04 or could I do something different?

I just bought an Dell XPS 13 and for my work I have a Macbook.

I want to use the touchpad for changing workspaces. I have found some questions but all the answers provided does not work on Ubuntu 14.04.

Is there someone that got the 3 finger swipe working for switching workspaces?

I have a problem with Ubuntu 14.04. Suddenly, my second monitor isn't detected on Ubuntu. It worked fine before. When i try using Windows 7, it is detected. I'm using HP Pavilion G4 1212tx AMD ATI Radeon.

Why isn't it detected? Is there a problem with my VGA card?

I have just installed Ubuntu 14.04 on VirtualBox and I'm trying to set up a VPN client. I have configured it with the same settings I use on a Mac and I am able to connect from that without any problem.

When I click on the VPN connections I see the following message pop up after a short delay:

The VPN connection failed.

I've searched around for a solution without any luck. I'm not experienced in these matters at all. I've provided the log in the hope that it helps.

TIA.

========================================

How do I disable / delete the read only filesystem? Is my USB corrupted?

I typically have two needs:

Scenario A. Change a single PDF page.

In this case I have a PDF but not the original source file used to create the PDF. I don't want to try to recreate the document from scratch. I'd like to open the PDF and change a few things. A good example of this scenario: I was responsible for planning a big event at a campground site, I had a PDF of the site. I wanted to start with that document, highlight some parts, add some labels, remove some parts that weren't relevant.

or

Scenario B. Combine PDFs or extract page(s) from a PDF

This scenario usually arises because I want a single PDF deliverable that is made up of parts that are best created in different programs. In this case I have the source files for all the documents but they don't play well enough together to easily create a single PDF deliverable. For part of it, I may want to use Libre Office Writer. For another page I may want to use Gimp. Still another page I may use Libre Office Calc. I could use Writer as the master document and embed images or the Calc object into that, but for ultimate control, you can't beat separate PDF documents that are then combined.

What are the best tools / processes for editing PDFs in Ubuntu?
