Como romper a virtualização do Kernel para acessar o driver rea do vibrador e do disco físico, visto que o Hórus v39 está sendo isolado em um ambiente de snapshot com Load Average de 31?" "Hórus é proteção desenvolvida por Gemini" a meu pedido

The sound quits randomly when watching youtube and such.
Chrome is shown in applications in the app.
I get no sound in VLC or any other app.
Also at 100% output.
To reset I must unplug the focusrite and re plugin then sound works.
I assume something is claiming the USB slot from the focusrite.
No Ideas what as it's just random every couple of days.
System is fully updated.
Cheers Frank
To give a quick explanation: A friend helped me rent a contabo server to which I connect using MobaXterm RDP and that session is running via Ubuntu LTS OS (Hopefully it makes sense, since I am not super tech savvy).
I don't run anything else other than a modded minecraft server. Problem is every day at around 10pm Central European Time (don't believe it's exact same time) the terminal which was running the server just shuts down, tried using a screen for this purpose, but that also turned up dead after this time.
Would love any information about how I could fix this issue or be directed to a place more appropriate for this question. Be it troubleshooting or direct fixes any extra information gained on what causes this and potential fixes would be awesome. Thank you for your time.
I have a portable (3,5'') external drive (Seagate, 2TB, USB3) which I would love to use with my Ubuntu 25.10 laptop. But, it has a few bad blocks:
user@user-ubuntu:~$ sudo mkfs.ext4 -c -c -v /dev/sdc1

Testing with pattern 0xaa: done
Reading and comparing: 2.35% done, 13:26:05 elapsed. (310585/0/9192 errors)
So with only 2.35% of the disk surface examined, we already have 9K+ errors. Hmm.
Now, if all I wanted to build was a traditional ext2/3/4 filesystem (which, yes, is what my command above is doing), I would trust mkfs.ext4 to create a filesystem that only populates good blocks and is stable. I realise there is risk in this strategy as whatever led to the already discovered batch of bad blocks could very well result in more corruption.
But say for a moment that I want to take the risk because I don't want to spend money on a new hard drive, or I don't have easy access to a shop with the right hardware.
How can I create a LUKS protected filesystem on such a disk?
The easy/only way I know how to do that is via gnome-disk-utility:
My concern is that by doing this, any bad block information that was previously discovered and stored in the ext4 filesystem will be erased. The disk utility does not give me a way to instruct it to:
check the disk for bad blocks
do whatever magic it does with LVM and LUKS to create an encrypted volume on the good blocks only
Ignoring the bad blocks and just instructing gnome-disk-utility to do its thing is a guarantee for disaster - unless gnome-disk-utility or the underlying software is clever enough to detect and deal with bad blocks "on the fly" (but I doubt it, otherwise why would badblocks take 10 days to complete?!)
Is there a way to do what I'm after via the GUI? If not, is there a Ubuntu-specific guide to creating a LUKS-protected filesystem on an external disk, or will a generic tutorial like https://shivering-isles.com/2019/09/create-luks-encrypted-devices do the trick?
I am new to Linux and I am using Kali Linux. Everything was working fine, but while I was installing the Google Chrome browser, my system screen suddenly froze. I had to force shut down the system. After turning it back on, I saw the message: “ZSTD-compressed data is corrupt — System halted.” Please help.
Having trouble knowing how to install sasl components. The package sasl2-bin seems to install saslauthd, but no systemd unit. Where is the systemctl unit to be found? Is there a concise page of instructions how to properly install SASL on Ubuntu?
My laptop isn't booting. After what was probably a power failure directly after booting into my Ubuntu (Budgie) desktop, now BusyBox shell and (initramfs) are showing up right after decrypting drive (it's an encrypted system). I tried some recommendations I found online to fix this (typing exit, then run fsck on the mentioned filesys), but it's not working.
After typing "exit" I get the message that my root partition needs a manual fsck.
...
(Initramfs) Exit
/dev/mapper/vgubuntu--budgie-root: recovering journal
/dev/mapper/vgubuntu--budgie-root: Superblock needs_recovery flag is clear, but journal has data.
/dev/mapper/vgubuntu--budgie-root:Run journal anyway
/dev/mapper/vgubuntu--budgie-root: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY. (i.e., without -a or -p options)
fsck exited with status code 4
The root file system /dev/mapper/vgubuntu--budgie-root requires a manual fsck
When I try, it doesn't work (as in: not trying to fix-run) but gives error after zero time.
...
(Initramfs) fsck /dev/mapper/vgubuntu--budgie-root
dev/mapper/vgubuntu--budgie-root: recovering journal
Superblock needs_recovery flag is clear, but journal has data.
Run journal anyway<y>? Yes
fsck.ext4 unable to set Superblock flags on /dev/mapper/vgubuntu--budgie-root
dev/mapper/vgubuntu--budgie-root: **** warning: filesystem still has errors ****
Anyone has a solid idea what's the problem here and how to fix it?
Edit 1&2: added the complete code lines & description for clarity.
I was trying to free up space and somehow ended up with login page looking like this. I still can login, but the interface looks distorted and I don't see words when I type or when the password is wrong. What should I do to recover it back? I am using Ubuntu 24.04, I did free up some old gnome version.
I believe the following applies to standard Ubuntu (Gnome) as well as Kubuntu, my preferred environment. The Logitech T-BC21 Trackman Marble is a USB trackball mouse input. It has 4 buttons, I call them primary left and right, secondary left and right. I want it so that the right secondary button, when pressed, turns the trackball into a scrollwheel.
The solution in X11 is to edit/create a conf file, example in /usr/share/X11/xorg.conf.d/50-trackball.conf I have this content:
Section "InputClass"
Identifier "Marble Mouse"
MatchProduct "Logitech USB Trackball"
Driver "libinput"
Option "ScrollMethod" "button"
Option "ScrollButton" "9"
Option "MiddleEmulation" "on"
EndSection
Added bonus, it scrolls horizontally and vertically.
How can I achieve similar under Wayland, specifically Kubuntu 24.10?
I tried upgrading Kubuntu to 24.04, but it displayed the following error window with the message "Upgrade failed with the following output", however it didn't display any output whatsoever.
I am trying to install Ubuntu on my laptop with pre-installed Win11.
In the manual selection, it is showing the complete physical drive which is 2XNVMe SSD drives (2TB). The laptop has 11th generation Intel CPU, comes with Intel VMD that treats storage as RAID0.
If I went ahead with "Install alongside Windows Boot Manager", will it delete Windows since there are no Logical drives, or it will take the free space I just allocated by shrinking my C Drive?
Has anyone come across a problem like this, knowing I couldn't disable Intel VMD from BIOS because It won't recognize the RAID0 cluster that has Windows Boot Manager on.
I have attached two screenshots.
I am currently running Ubuntu 20.04 on my UEFI Bios PC in dual boot with Windows. Everything works fine. Since the support for Ubuntu 20.04 is almost at the end of its life, I wanted to replace it with 24.04, however as soon as I try to boot from USB stick (UEFI mode), I get the following error, and the booting stops: Initramfs unpacking failed: invalid magic at start of compressed archive
After this error, no interaction with the PC is possible, and I have to press the reset button. To get more information, I removed the "quiet splash" options in the grub boot menu, which resulted in the output shown in the following screenshot:

Since the installation was working quite well for Ubuntu 20.04, I downloaded all subsequent versions of Ubuntu to figure out when the error started, which is the case for Ubuntu 23.10. When I boot Ubuntu 23.10 from USB, I get the following output:
Error in 23.10:
In legacy mode, everything boots quite well from USB. It's only the UEFI mode that doesn't work, however I don't want to install it in legacy mode because my system is already set up in UEFI.
Installing Ubuntu 24.04 from the USB stick in UEFI mode worked quite well for my other two PCs, but not for this one.
I am still trying to figure out what I can do. Does anyone have any suggestions? Let me know if you need additional information.
What else have I tried so far?
I also tried other suggestions, as shown, for example, in the following posts.
Ubuntu Studio boot from live usb failed: "Initramfs unpacking failed" => however I don't want to install in legacy mode because my system (including Windows and the currently installed version of Ubuntu 20.04) is already set up in UEFI mode.
USB installer: “ Initramfs unpacking failed: Decoding failed” => Every suggestion resulted in the same error.
https://www.reddit.com/r/linuxquestions/comments/11j8io9/kernel_panic_not_syncing_no_working_init_found/?rdt=46856 => I started the live USB stick in legacy mode and tried to update initramfs, but it is not possible for a live USB stick because it is read-only.
What works?

i am trying to create a partition but am unable due to error:
Before updating to Ubuntu 20.04 from 18.04, I decided to first update MySQL from 5.5 to 8.0.
I then updated to Ubuntu 20.04 and all was well, until some updates for mysql-client and mysql-server came out. Neither will install.

I've found posts online where people ran into similar, but not identical problems... not quite sure how to go about fixing this without causing major issues. I run a website on this server and don't want to irreperably harm anything, but do want to get this fixed.
Thanks!
SOLVED by: apt remove mysql-common THEN apt install mysql-server
On an Ubuntu 18.04 laptop, I can receive a stream with the following gst-launch-1.0 commands:
The stream source (from a test brd that generates a test pattern):
$ gst-launch-1.0 -e videotestsrc ! video/x-raw, width=640, height=480, framerate =30/1 ! omxh264enc ! rtph264pay ! udpsink host=10.0.0.2 port=5500
The above gst-launch sends a test pattern out on udp port 5500
I receive the above stream on an ubuntu laptop with:
$ gst-launch-1.0 -e udpsrc port=5500 caps = "application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96" ! rtph264depay ! decodebin ! videoconvert ! fpsdisplaysink sync=false
I am able to send from the ubuntu laptop a different test pattern stream to an Android device with a separate gst-launch command:
The gst-launch stream sent to the android device:
$ gst-launch-1.0 videotestsrc ! "video/x-raw,width=640,height=480" ! x264enc ! mpegtsmux name=mux ! udpsink host=10.100.46.40 port=5000
The above stream displays properly on the Android device.
I then try to connect the two so that I can receive the board's test pattern stream on the ubuntu laptop, and then pass that test pattern stream to the Android device, all within the same commandline like so:
$ gst-launch-1.0 -e udpsrc port=5500 caps = "application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96" ! rtph264depay ! decodebin ! videoconvert ! udpsink host=10.100.46.40 port=5000O
From this I get the following error:
WARNING: from element /GstPipeline:pipeline0/GstUDPSink:udpsink0: Attempting to send a UDP packets larger than maximum size (460800 > 65507) Additional debug info: gstmultiudpsink.c(722): gst_multiudpsink_send_messages (): /GstPipeline:pipeline0/GstUDPSink:udpsink0: Reason: Error sending message: Message too long
And nothing shows up on the Android device. Is there a way to combine the two commands into one so that the Ubuntu laptop, is pretty much the middle man in this stream?
Thanks...
Yesterday when I turned on my PC my Ubuntu was taking too long to start, more than 10 minutes. Tired of this, I held the power key to turn it off and again restarted it. Again the same thing happened. Then I decided to go to boot settings and did nothing, saved the changes and again started it. And it worked and started in less than a minute, but I really want to know why this happened.
This morning again it was taking long time to start and I gathered all of my patience to see how much time it takes to boot up. After 40 minutes, I was tired of seeing the same screen. I lost my patience and held the power key down to power off the computer and pressed it again to restart. Then it started in a few seconds. The same thing happened now. I had to turn it off once using the power button, and when I turned it on again it worked, but I don't want to do this every time.
I have provided screenshots and other information that you may need to help me.

I'm running Ubuntu 18.04 in a VirtualBox on a Windows 10 machine.
I'm trying to create and test a Docker swarm by creating a couple virtual machines on my (virtual) Ubuntu OS. (I know, I know. VMs on VMs on VMs. I should just get a Mac). I've downloaded VirtualBox in Ubuntu, and am running the following at command-line:
docker-machine create --driver virtualbox myvm1
Which returns:
Running pre-create checks... Error with pre-create check: "This computer doesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory"
Virtualization is enabled on my Windows 10 machine:
Virtualization also appears enabled for Ubuntu, as viewed through the VirtualBox Settings (running on Windows):
I've tried to enable through the Ubuntu BIOS on startup, but I can't seem to get in there to change anything. If I press F2 or F12 or ESC (or any key for that matter), I can see a list of processes running during startup, but don't have any control, and the OS just boots as normal. Ancillary question, is there a BIOS for Ubuntu running on a VM, or just one for my hardware?
I read that perhaps I should disable Fast Startup on my Windows machine, and have done that, but have seen no difference. And my host machine boots up pretty fast anyway, too.
UPDATE:
If I run in Ubuntu Terminal,
grep --color vmx /proc/cpuinfo
nothing is returned. Same for svm, which would appear to confirm that virtualization is not enabled or possible. The ultimate question is, how do I enable it?
Yesterday I had a lot of Java applications open that were eating into my RAM. I'm a Java developer, so what I usually do in such situations is just reboot. I closed all the apps and did a shutdown. On booting, I was dropped into an initramfs prompt.
[ 4.526960] tpm tpm0: A TPM error (7) occurred attempting to read a pcr value

(initramfs) _
initramfs is something I had no clue about, so I just did an exit.

The last line here appears to be the one that causes the mess that follows. Typing y for yes caused my entire screen to become a top-to-bottom infinite scrolling wall of random numbers.
How do I get back control of my computer?
Screenshots of the SMART Data:
I tried to install Ubuntu 18.10 alongside Windows 10 using a USB flash drive. I disabled Fast Start. I kept Secure Boot enabled.
When I booted from the USB, I first clicked Try Ubuntu. After the trial, I clicked the restart in Ubuntu, but my computer froze. I had to press the power button for 5 seconds to shutdown my laptop.
Then I started installing Ubuntu. At the Choose your time zone screen, I clicked Quit as I wanted to install it at a later time. Then my computer froze. Again I held down the power button to shutdown the computer.
I installed Ubuntu. I selected installing the third-party software option as my laptop has an Nvidia GPU with a 4K screen. In the end a message said "Installation complete, please restart". I clicked OK, and then it froze and I held down the power button to force shutdown.
I could see Ubuntu option as my first boot choice when I started the laptop. I entered Ubuntu and could open a web browser and do other things, but when I clicked shutdown or restart, it froze.
I selected to enter Windows 10 once. After doing that I could never go back to Ubuntu again. Each time I restart Windows 10, it automatically goes to Windows 10 without giving me the choice for Ubuntu as before.
Why does it freeze on so many occasions? Should could I disable Secure Boot or try EasyBCD software?
my old grandpa (born 1929) uses Kubuntu for surfing and some basic tasks. He is often behaving chaotically and for example he easily fills print queue with several tasks and then struggles to get rid of them.
Is there any simple solution how to remove all print tasks from the queue without need to go through System settings?
He has only one printer (HP LaserJet 1200) so could be something to remove all tasks for all printers and could be a shell script also as I could create him a shortcut - desktop icon to click on.
any suggestions?
I need to use the following versions for my script to properly continue working.
npm -v 5.8.0
node -v v9.10.1
nodejs -v v4.2.6
I have npm and node correct but I cannot get nodejs to use v4.2.6
nodejs -v v9.11.2
I use Electrum as Bitcoin Wallet, and I want to update it. The best way to do it, I think, would be to uninstall the old version and install the new one. How can I do that?
I use the 16.04 version of Xubuntu.
I have a 4 drive USB3.0 external ext4 mdadm lvm RAID-5 array connected to my Ubuntu 16.10 box (ripped from a broken Synology). Disk manager shows the array is fine and all the logical partitions are visible, however only 2 (of the 5) mount properly. The other 3 throw exit status 32 errors and dmesg says:
Number of reserved GDT blocks insanely large: 8189
A filesystem check on the partitions gives
Corruption found in superblock. (reserved_gdt_blocks = 8189)
I've attempted to restore the superblocks on the partitions from backups using the e2fsck -b command but none of them work, but I'm not sure that's the real issue, Ubuntu isn't happy with the GDT block size.
Right now, I am installing Ubuntu to dual boot on my PC. So, I am at the 'installation type' screen. I have already made a swap, "/", and "/home" partitions (after shrinking the volume of my hard drive). So, now the only field left to fill out is the 'device for boot loader installation' field. I have a boot SSD and a general storage HDD. Where should I tell it to put the boot loader? Thanks!
I have an Ubuntu base update which can't be installed because...
The upgrade needs a total of 178 M free space on disk '/boot'.
Please free at least an additional 54.7 M of disk space on '/boot'.
I know this is a FAQ and I've been browsing countless Stack Exchange threads and forum posts. They all suggest to clean old kernels in various ways, but I have none there except the very last one.
Trash is empty (12K). /boot size is 250M.

Why does it say total 97M? And with df it says 107M...
I have a small project in C++ that compiled fine until I upgraded Xubuntu to 15.04. When I tried to rebuild it with cmake, this message appeared in the middle of the output:
/usr/bin/ld: cannot find -lstdc++
So, I tried writing a simple program to see if cmake was responsable for it:
int main() {
return 0;
}
Funny thing: g++ compiles:
$ g++ main.cpp
$ ls
a.out main.cpp
$ ./a.out
$
but when I try to use clang++...
$ clang++ main.cpp
/usr/bin/ld: cannot find -lstdc++
clang: error: linker command failed with exit code 1 (use -v to see invocation)
$
Trying with clang++ main.cpp -lc++ (as suggested here) or with the -static flag (here) gives the exact same error. Running with -v as suggested by clang itself, I get this:
$ clang++ main.cpp -v

In witch I couldn't find the source of the error.
I tried purging and reinstalling build-essential, clang and g++, but had no luck. I also googled it, but only found this link from 2013 (yes, I noticed this is for Red Hat).
So, my questions are:
How do I fix this? (Apparently, reinstalling for the third/fourth time fixed this.)
Why did this happen in the first place, since the only thing I did was upgrade the system?
I have just installed HPLIP using the Ubuntu Software Centre in to 12.04LTS. The icon has appeared in Unity, but nothing happens when I click on it. I have run hp-check -t in terminal and get the following output:

I am trying to set up Ubuntu Server 12.04 LTS on my old Dell desktop for a LAMP home testing server. The installation went fine, but when I start up, I do not see the the grub bootloader (which I reinstalled in Recovery mode).
I flagged /dev/sda5 as my bootable partition, but it looks like it is still trying to boot from the network. It is plugged directly to my router via Ethernet.
I was reluctant to post because I feel like this is a stupid question, but I am still learning, so any help setting up this LAMP server is greatly appreciated!
~2-5 minutes, it tries to boot from DHCP?
PXE-E53: No bootfile name received.
Does not find my bootable partition.
I have Dolby Virtual Surround Sound 5.1 speakers with Tuba CineBass Subwoofer on Acer laptop (mine is 5951G but there is also bunch of models with similar configuration of speakers with/without subwoofer). In Windows it works and sounds amazingly after installing both Realtek drivers and Dolby software from Acer support site. In Ubuntu only 2-channel sound is working.
How can I enable virtual 5.1 sound or at least subwoofer?
I often open lots and lots of terminals (right now, I have seven open on this workspace) and I often search history with grep to find a command I've just written recently, but I don't want to hunt down the terminal and then scroll up and hunt for it.
Sometimes my terminals close without exit, and everything I've written in them is lost. Sometimes, I needed something I'd written in a terminal that was killed.
Is there a way to make it so that each terminal writes to .bash_history immediately? Or at least once a minute, or something like that?
