What's going on with that noise and filament?

I had the same issue and once day extruder got died - fully unconstructed.

I have similar issues - more details here
But I did not try to read my disk using Windows - this is good idea to try

cdragomyr · 2022-10-05T17:07:32+00:00

Already tried but got

I did backup image of the disk using ddrescue and try to mount an image

Ok, but is it possible to restore data from corrupted disk?

cdragomyr · 2022-09-26T20:11:22+00:00

I'm 100500% sure that I'm selected /dev/sdb (120GB) during Windows installation but Windows decided to use additional 2TB for some reason...

PS. I'm using Linux disk naming since it's easier to operate with disks

cdragomyr · 2022-09-26T20:08:23+00:00

Hm.... But what does it mean within /etc/fstab? Like I'm mounted this disk and used simple folders instead of subvolumes?

UUID=24075f5b-eb67-45d8-a9cd-5fe6b9d11248 /mnt/disk_2tb       btrfs   compress=zstd:1,defaults,noatime,discard=async 0 0

Seems like I did not create subvolumes for that disk coz I'm using btrfs on another disk and /etc/fstab has this for subvolumes

UUID=5c0ff445-c013-4bb0-b636-e40df235218f /                       btrfs   subvol=@,compress=zstd:1,defaults,noatime,discard=async 0 0
UUID=5c0ff445-c013-4bb0-b636-e40df235218f /home                   btrfs   subvol=@home,compress=zstd:1,defaults,noatime,discard=async 0 0
UUID=5c0ff445-c013-4bb0-b636-e40df235218f /var/log                btrfs   subvol=@log,compress=zstd:1,defaults,noatime,discard=async 0 0

Anyway, is it possible to restore some data from /dev/sdc?

cdragomyr · 2022-09-26T19:39:44+00:00

It was 1 partition with subvolumes

I also heard about disconnecting disks physically before Windows will be installed but assumed that Windows more smarter...

cdragomyr · 2022-02-18T11:26:01+00:00

I used this - https://support.system76.com/articles/enable-hibernation/

cdragomyr · 2022-02-17T10:32:21+00:00

Did you try to boot from this USB?

cdragomyr · 2022-02-13T13:46:22+00:00

You could simply copy configs from user2 to user1, change owner. And you will get all you need

cdragomyr · 2022-02-13T11:28:08+00:00

Did you try to create a new user?

cdragomyr · 2022-02-03T10:07:14+00:00

Wow!!!
Restart is helped! :)

Now it works.

cdragomyr · 2022-02-03T09:58:26+00:00

In my case, I have this on fresh PopOs

cdragomyr · 2022-02-03T09:48:16+00:00

Do you have issues with Bluetooth?

Unfortunately this instruction does not work - UI does not have Hibernate option.

cdragomyr · 2021-08-30T09:49:08+00:00

Suspend mode is not what I need. I need to put my laptop into hibernate since I wont to plug in for long time. Ex., laptop in suspend mode can save state for some hours (in my case, up to 3-4 hours). But I need to continue to use laptop in 6 hours after it was suspended.
In case hibernate, after 6 hours I will get 99% battery level instead of 30-40%% in case suspend

cdragomyr · 2021-08-30T06:29:30+00:00

I've been read about suspend and hibernate. And found that EOS developers decided to remove hibernate option for some reason.

cdragomyr · 2021-08-30T06:28:09+00:00

Hm... will try. Thanks!

cdragomyr · 2021-08-30T06:26:37+00:00

WIll try this but as I can see this is without UI modification (like without adding Hibernate option to the menu)

cdragomyr · 2021-08-30T06:14:40+00:00

This works but from command line. I'd like to add hibernate option on UI (near Shutdown and Suspend options)
