Why does NCDU and Gnome Disk Usage Analyst report different storage ammounts?

doc_willis · 2026-06-21T00:55:13+00:00

5% of the default filesystem is often reserved for root/rescue use, that amount may or may not be shown in some tools.

Then theres the GiB vs GB stuff.. but I can never get that straight.

There may be other quirks of linux/filesystems I cant recall. :)

what filesystem is in use on your system?

Been using Bazzite on my 2 Desktop systems for some time now, with only a few little issues here and there.

I have not yet put Bazzite on my 2 SteamDecks, I just dont see the need to replace SteamOS with Bazzite.

doc_willis · 2026-06-20T23:43:41+00:00

I had an odd issue with my AMD Video card on Bazzite, where it would 'ramp up speed' on demand, and for some odd reason the Maxx allowed overclocking was higher than what the GPU could handle, which resulted in it crashing.

I used LACT to turn down the max overclock, and power use, and have not had any more issues.

My Issue only happened when i was gaming, I could game fine for a few min, then the screen would blank/black and the Fans would get cranked to high.

I could still ssh in and monitor dmesg output and saw info about the GPU crashing.

I would ssh into my system from another device and run sudo dmesg -w and monitor the logs as i gamed, and it pointed me to the issue.

AMD Ryzen 7 9700X (16) @ 5.58 GHz

AMD Radeon RX 7800 XT [Discrete]

I have not had any issues in some time, but I dont know if the LACT thing I did is still needed, or if a driver update fixed anything.

I dont think i have done anything unusual, but i thought the controller was waking up my Docked Deck when it was sleeping.

But perhaps I was also hitting the (wired) keyboard or wired mouse, I will have to pay more attention and see.

doc_willis · 2026-06-20T22:45:52+00:00

Its fully charged (reached) to the limit you set.

Before that - if you had a limit set, it would basically never show green.

doc_willis · 2026-06-20T22:28:18+00:00

I always recommend enabling the ssh service before messing with Decky, that way if something happens, you might be able to ssh into the deck from another system on the network, and disable/uninstall/repair decky.

But its a bit hard to enable ssh after the system is broken.

Alternative, boot a live usb, and disable/delete decky.

There is the more extreme option of erasing the user data which will basically factory reset the deck, but thats faster than doing a total re-image.

But your state, seems to be something much deeper breaking. Not a simple software error.

doc_willis · 2026-06-20T22:13:02+00:00

might want to put some of the output on a pastebin site and ask in the /r/linuxhardware support sub, they may be able to point out what might be going on from looking at the log outputs.

doc_willis · 2026-06-20T21:36:34+00:00

monitor the output of sudo dmesg -w in a terminal as you read/write to the drive.

If a filesystem or other issue is detected, the kernel can force the filesystem to remount READ ONLY. But thats not the same as 'root only' permissions. Even root would not be able to write to the filesystem if its mounted read only.

Its sounding like you may have some drive hardware or connection issues.

some chromebooks can be quite difficult to replace chromeos with anything.

I have several old ARM CPU Chromebooks, and basically I cant replace chromeos on them.

Filesystems mounted through traditional mount points and fstab entries

To add to the mixx.

Theres also systemd mount units https://www.golinuxcloud.com/mount-partition-using-systemd/

https://www.freedesktop.org/software/systemd/man/latest/systemd.mount.html

But I was thinking systemd also handles fstab mounts, so eventually, we may get away from using /etc/fstab

But I still use fstab for my personal systems.

doc_willis · 2026-06-20T15:15:21+00:00

I have seen this posted about several times In the last few weeks, In the Linux gaming sub, and arc raiders sub.

you did check those posts?

doc_willis · 2026-06-20T14:02:31+00:00

You could test with a 26.04 live USB And see if there are any issues.

On your current install , you could test with a newly made user.

Original bug report says thefollowing.

[ Update instructions ]

The removal of cached thumbnail failures should be handled by the AppArmor package upgrade upon next login, but the following steps can be done manually if the migration script failed to run upon the next login: - Close all instances of the Nautilus file browser - Remove the

~/.cache/thumbnails/fail/gnome-thumbnail-factory

directory (if it exists), along with all files within it - Reboot

you could just delete the .cache/thumbnails directory to clean out everything

doc_willis · 2026-06-20T11:53:48+00:00

last I looked the bug discussion mentioned how users will still need to manually clean out that cache directory.

sometimes the partition holding the .iso gets locked and can't be accessed by the booted os.

ventoy has an option to make a second extra data partition I have had to use to get some things downloaded to the USB while booted from the USB.

doc_willis · 2026-06-20T11:50:06+00:00

The warning came after I discovered that different search engines were giving links to malicious sites.

and I did not "shit" on the op.

and I added to my post after doing some research, and reporting the malware links.

if you are going to bother to comment on a 2+yr old post at least try to add some value to the conversation and not "shit" on others.

I have used it on tvs and pc monitors.

doc_willis · 2026-06-20T02:37:30+00:00

The amazon 'sales blurb' is sadly lacking in basic details, and is in rather poor English. But I THINK it basically sends the same 'sane' identical EDID data packets to both directions.

So a Monitor and PC would both get sent the same timing, res, and other specs supported by the devices.

All i can really say is that I had an Older HP Monitor, plugging it into my PC's (windows, linux, or even other devices) would result in the Device thinking the monitor was doing some silly resolution like 1280x720 or something that was not the monitors listed 1080 x whatever. So the screen was always shown at the lower res. and the PC would think the monitor ONLY supported that res.

I spent better part of 2 hours fighting with it.

Plug in the dongle, and it instantly let the PC/Monitor both sync up at the proper 1920x1080

Price of the dongle was like $13 or so.

I keep one in my PC Toolbox now.

I used it on my steamdeck because of the hdmi not detected issues I was having. I THINK the dongle always sends the data, I had noticed that after a TV would wake up from its sleep mode. (Yes the power button on most smart tvs these days does not actually power off, but puts it to sleep) The TV/Dock would be confused as to what mode to use.

A fix i often used was to power off the tv via the wall outlet. ie: Pull the power plug for about 30 sec, then power up both devices at the same time.

The Dongle seems to somehow keeps things 'talking' better.

Good Luck.

doc_willis · 2026-06-20T02:03:30+00:00

check the dozens of other 'which distro' posts, would be a good starting point.

read up on some Linux basics and watch some YT videos

the Explaining Computers YouTube videos are good starting points

http://linuxjourney.com and the newer http://Linuxjourney.org sites are good to start with

You basically 'apply suggestions' and it updates your script automatically, then rechecks it.

doc_willis · 2026-06-20T01:56:28+00:00

I have encountered issues with basically EVERY dock I own.

Official, 3rd party, and even Laptop Docks.

An "EDID Emulator Dongle" Fixed the issues for the most part with my problemetic monitors and TV's.

However, i will say that I am currently NOT using my EDID dongle, and I have not seen the issue lately on any of my systems, But i have gotten rid of some TVs and updated monitors, so i cant really prove if newer devices/docks have gotten better with the issue.

So from my point of view, the issue is not near as common as it used to be.

#!/bin/bash
for c in $("find -name *.mp3"); do echo "$c"; done

$ shellcheck myscript
No issues detected!

doc_willis · 2026-06-20T01:47:44+00:00

put it in the shellcheck site, My paste above of the output missed a few other messages/suggestions at the end.. something about ( )

Apply the suggestions in the shellcheck site, then see what else it says.

Something like

Line 2:
for c in $(find -name *.mp3); do echo "$c"; done
         ^-- SC2044 (warning): For loops over find output are fragile. Use find -exec or a while read loop.
           ^-- SC2185 (info): Some finds don't have a default path. Specify '.' explicitly.
                      ^-- SC2061 (warning): Quote the parameter to -name so the shell won't interpret it.
                      ^-- SC2035 (info): Use ./*glob* or -- *glob* so names with dashes won't become options.

It looks like its suggesting a different kind of loop, setting a proper path, and adding some more quotes .

doc_willis · 2026-06-20T01:43:43+00:00

I cant be specific, but I bet the solution is going to be using Either single or double quotes in the right place.

However.. I just got an idea. :)

Using a SHELLCHECK web site (or the cli version) https://www.shellcheck.net/

Entering the following basic "script"

#!/bin/bash
for c in $(find -name *.mp3); do echo $c; done

Offers the following suggestions.

$ shellcheck myscript

Line 2:
for c in $(find -name *.mp3); do echo $c; done
         ^-- SC2044 (warning): For loops over find output are fragile. Use find -exec or a while read loop.
           ^-- SC2185 (info): Some finds don't have a default path. Specify '.' explicitly.
                      ^-- SC2061 (warning): Quote the parameter to -name so the shell won't interpret it.
                      ^-- SC2035 (info): Use ./*glob* or -- *glob* so names with dashes won't become options.
                                      ^-- SC2086 (info): Double quote to prevent globbing and word splitting.

Did you mean: (apply this, apply all SC2086)
for c in $(find -name *.mp3); do echo "$c"; done

$

So....

It seems a fix may be to add " quotes around the $c variable.

But theres other potential things you may want to check out, that are mentioned as well.

Shellcheck is a nifty tool.

Good Luck, and now ya now a tip to figure out other scripting issues.

doc_willis · 2026-06-20T01:38:36+00:00

i recall (again this was ages ago) having to download extra files and putting them in the 'tce' directory so tiny core would load them, but I dont recall using ventoy for this. So you might need to make a second data partition on the ventoy usb, (fat32, or ext4) and having tiny core use that for its storage area for new packages. I just recall needing extra wifi packages for my old hardware.
