I recently installed a fresh Kubuntu 22.04 as a replacement for my "old" 20.04 system. I am facing an annoying issue when using the scroll wheel on my mouse, and I hope someone might be able to help...

Thank you for your idea, but that would not work since the drive is encrypted.. I have also looked at the "/sys/block/sd*/removable" attribute but that is already "0".

You could simplify your folder name generation:



# Manual user
backup_folder=/media/<user>/usb_hdd/backups/$(date +%Y-%m-%d)

# Current user...

I have a USB drive which is always attached to the computer and I would like that particular drive not to be listed as ejectable in "system tray" and file manager(s). Is that possible?

Are you 100% sure that you condition works as it should?



EXCLUDE=""
if [ some_condition ]; then EXCLUDE="--exclude=/*"; fi
# Debug print to verify condition
print ${EXCLUDE}
# Proceed...

Have you tried to use "$EXCLUDE" instead of "${EXCLUDE}"?

In your example, the "*" makes little sense. Would have made sense if you would want to exclude all files with a specific extension, like...

The common issue with cron is that there is no environment available so if any of the commands rely on information from the env, they will fail. You could try to debug you issue by creating a shell...

In #14 I suggested that a bad ethernet cable could be the culprit, did you try another cable that is known to be good for gigabit?

If you are using a managed router, try to enter the settings of the router and see if the link speed for the slow performing system is as it should be. On my NETGEAR router, the information is...

Did you enable the service? If you named the service "nomouse.service" and stored it in "/etc/systemd/system/", then try to run "systemctl status nomouse". If the service shows up as "disabled",...

What type of storage is used on your Linux system? If it is encrypted, how? Have you verified that your Linux system actually has a gigabit connection to the (I assume) router? Even if a cable is...

Have you tried to disable hardware acceleration in FF settings?

The problem with SSD's and adapters is, that TRIM usually not work with adapters (definitely not with the IDE/PATA interface). Some USB adapters support the UASP which implies TRIM, though.

TRIM...

The system drive is mounted with the option "errors=remount-ro" which means that if errors occur on the volume, it is remounted as read-only. This may be the cause of your problem and I would suggest...

You are probably right. I've not been into Windows for a long time and I was not aware if there was such a thing as "Windows Lite" with limited space usage ;)

If he wants to keep his installation of Windows, an ISO from MS is not an option.

In your command, dd sees /dev/sdb1 as a file with the size 7.3GiB. Had the USB stick been 64GB so would the image created therefrom with dd. The dd command will not remove unused space, you need...

Yes, you can "matryoshka doll" your encrypted containers, but that would make very little sense. Understanding the encryption parameters and how they impact the security of the encrypted data will be...

I had this post once and in that particular case default mount options had a performance impact of more than 50%. I did also try with noatime but that had much less impact than mounting as read-only....

Ubuntu uses the default mount options unless you tell Ubuntu to do something different. In the first picture, you have mount options for the file system at the bottom, entering "noatime" into that...

For some file systems, file access time is enabled by default which means that each time a file is read from, the driver writes back to disk in order to update the files access time. By (manually)...

I disagree. If one would try to access an encrypted volume, the usual approach would be to run through a list of well known passwords. If that does not give access, brute force may be one of the next...

I would strongly encourage you to NOT use a passWORD but instead use a passPHRASE! An example of a strong passphrase could be: "in the field there are 2 cows and a sheep". It is easier to remember...

Great! Please mark the thread as solved.. :)

Try this then:


sed -i 's/seed=.*/seed="'$newseed'"/' /path/to/file.txt
