After 20 years my xp machine broke. In order to save money I bought a used desktop pc and I installed linux mint..
On my home power gets cut often. With windows xp about 2/10 this was happening I had to check disk and fix errors and no settings were never touched. Now with mint every time this is happening settings are reset to many apps. With a live usb I use disks to check and fix errors on the filesystem, but settings are still lost. Is there any way to avoid this?
Do not tell me that I need a ups. Just answer me if I can avoid this situation when power gets cut. Thanks for your time.

Re: Power cuts and lost settings
Be exact. What applications?Now with mint every time this is happening settings are reset to many apps.
As some desktop environments and applications may use the default settings and not the saved settings.
Can you give output of command ?
Code: Select all

It's about life expectancy.
- Interrupting the power supply during a system update may break your system.
- Interruption of power to disk drives can sometimes scratch / damage the hard drive.
I don't know, maybe SSD drives are more resistant. But my SSD don't have SMART technology, so I don't know when will broken.
I have very very small, cheap "PowerWalker" UPS. It's enough for me to turning off the computer.
Laptop users have batteries and do not need a UPS. Because it is the same.

It's not a total solution and you will still have to check-fix for errors the disk bur you can save on a usb the hidden folder .config of your home folder and restore it when applications settings are reset.

Re: Power cuts and lost settings
if you refuse to get a UPS, then you must at a minimum use Timeshift and have it storing to different Partition or /HDD/SDD
and set the backups to at minimum of 12 hours apart....
then if the power fails, boot up again, and use the last backup to Restore from.
IF, however, you are loosing DATA, that is different, you need to use BackInTime and configure it much the same as above.
In my case, I have a Win7 Desktop that has never been powered off since I bought it back in 2006.....
it has a 1500W UPS on it with the OEM software that powers the Desktop down when a Utility Grid power goes away.

You need a UPS. And may without one be helped by mounting your /home filesystem with the

Your situation is a good reason to buy a laptop instead of a desktop. Built in battery backup.
Linux delays disk writes for up to a minute. If you are losing the last minute of activity, you can set the write delay to a shorter interval.
For losses of settings over more than a minute, it depends on the application with some applications having their own built in delay which might be 5 minutes. Please give examples, the application and how long between the setting change and the power failure.

Eh, if it uses the system in a virtual machine, then the virtual machine will restore the previous system.
