How Do You Run the ArpON Daemon at System Boot?

I want to start the ArpON daemon at system startup, but I didn’t see it anywhere in the documentation on how to do so. How do you make sure the ArpON daemon is running?

Many time my Android 5.0 & 6.0 mobile become slow while working i checked it In process stat in developer mode that there are many of apps running and using RAM even after closing the app it means they are memory resident may be for notification and running in background.

boot – Ubuntu 20.04: stuck GNOME

I need help with the following problem:

I am using an Ubuntu 20.04 virtual machine and when I start it it does not boot and stays stuck as shown in the image below.

enter image description here

Started GNOME Display finishes up…ally. system changes.pp link was shut down…

I would like to know how to solve this issue.

boot loop – SystemUI.apk and framework-res.apk causes bootloop after being modified

Hi I’m using a stock LineageOS rom specifically android Pie (LineageOS 16) and I’ve been modifying system applications, such as SystemUI, framework, gallery, sms etc. before (on samsung ROMS) and so far I haven’t got any problem aside from forgetting to set the correct permissions on each apk.

Though when I switched to LineageOS, it seems that I can’t simply modify the framework and systemui. I tried the usual way of decompiling and compiling an apk using apktool, then, to sign the apk with its previous/original key, I use the files from the “original” folder in the decompiled apk then build the apk again. Somehow, when I try to replace the apk in my phone, set the correct permissions, and reboot, it will result to bootloop.

Did I miss anything? Do i need to sign it with another key? Do I need to disable signature-check on my Android?

boot – “Cryptodisk not found” after new installation of unencrypted Kubuntu

I attempted to have a clean install of kubuntu onto an SSD with KDE Neon which was encrypted with LVM. Both the HDD and SSD are now unable to be booted, and the error “Cryptodisk not found” appears when booting is attempted. I am not too familiar with GRUB, so I may be missing a few things. I have no desire to save anything that was on the SSD.

dual boot – My Linux Mint Cinnamon’s audio is acting weird

So I just downloaded the latest Linux Mint Cinnamon alongside my Windows 10 (dual-boot) and installed it 2 days ago.

When I boot up my PC, there are 3 possibilities:

There is no sound. When I go to the sound settings, it only shows "Digital Output (S/-PDIF) Starship/Matisse HD Audio Controller" (which is selected) and I doesn't output sound.

There is sound but buzzy. When I go to the sound settings, it shows the one I mentioned before, and my monitors built-in speakers (which is selected). The audio sounds buzzy.

There is sound and it is normal. The same circumstances mentioned on 2., But everything works fine.

When I get 1. or 2. I usually restart and basically it randomly selects one of the three. I restart until I get 3. Is there a solution to this? I can provide screenshots if needed.

boot – Failed to activate /swapfile – not booting – Ubuntu 20.04

Almost similar to System Not Booting – Failed to activate swap /swapfile

So far, i tried the recovery option –

sudo swapoff -a           # turn off swap 
sudo rm -i /swapfile      # remove old /swapfile

2nd command gave me a read-only filesystem

So, i switched over to a USB- Try Ubuntu
My disk partitions are as below : with /dev/sda4 earlier the root option

I think my fstab is screwed up and while i wait for answers, i can just change the /dev/sda4 line from

/dev/sda4 /mnt/sda4 ext4 errors=remount-ro,x-gvfs-show 0 1


/dev/sda4 / ext4 errors=remount-ro,x-gvfs-show 0 1

and reboot and see if that works.

data recovery – Question on accessing salvaged Ubuntu boot drive

Not a power user, so this may be a very stupid question. My ever-trusty decade-plus old (probably closer to 15 than 10) Ubuntu desktop died. Used it for web browsing and email only. Dead-dead so I assume either a MOBO or a PSU failure. Frankly not worth fixing. For a temp fix I found a windows 10 mini that I purchased last year as a backup to my Windows laptop (wanted it as we went to remote desktops when Covid hit). Am I correct in assuming the easiest way to access this is to slap it in an external SATA enclosure and dual-load Ubuntu onto the mini? Last time I tried something like that many moons ago Windows did not even see the drive. Unfortunately I have been lax in backups and my last 6mo of emails are still in there (Thunderbird). Everything else I really do not care about. This is just for a temporary fix until I buy a new dedicated mini for Ubuntu email/web browsing (prefer to keep the Win10 for emergencies per the original purchase).

Thank you.
