[Unstable Update] April 2026

No significant improvement.

As you see i copied it with Thunar here:

Kingston DataTraveler 2.0 USB Stick with exfat formated. So a Ventoy Stick like yours but USB 2, not USB 3.

Well, then I don’t think that the speed drop is caused by the udev-usb-sync package, because the speed goes up to ~4MiB/s and drops again. That means, it fills the write cache fast and is bottlenecked by the usb device. It might simply be used up. So that is the actual speed of your device. Other than that makes no sense. Provide also the result on linux619 and/or below.

What is the speed without a cache?

Run this on the terminal:

dd if=/dev/urandom of="/run/media/$USER/Ventoy/testfile" bs=1M count=50 oflag=append,direct conv=notrunc

Exchange of="/run/media/$USER/Ventoy/testfile" with the real mount path to the stick.

In any case, I resolved the sudden drop in speed by slightly increasing the write cache. The only drawback is that it now takes a few extra seconds to complete the write process after the progress bar has finished.

It is quite often that changes in the fundamentals - the kernel - requires applications or scripts to adjust.

I have played with the values and and I am almost certain this is a kernel issue and we will have to wait until the final release, which should be any time soon.

/dev/sdg /dev/sdf /dev/sdh is (likely internally connected to the USB-bus) card-readers on my system with no cards inserted

With modded values 0.1 and 1.6 it is impossible to copy an ISO to the disk.

The dolpin dialog displays an estimated copy time which elevates from 1m to days - up and down - until I cancel the copy.

I really need to take some time and implement some kind of off-switch

udev-usb-sync {disable|enable}

Add or Remove a config DISABLED - which, if it exist, disables makes the script exit without doing anything.

@linux-aarhus

This is my WD MyPassport

Could it be that your drive is a firmware-managed SMR which known as CMR by the kernel? That could explain this behavior. My disks are all real CMR.

@linux-aarhus

The dolpin dialog displays an estimated copy time which elevates from 1m to days - up and down - until I cancel the copy.

Could you please test the script above so one can see that?

@megavolt

Here is the script, so we can compare. Run it like: usb-bench /mount/path

usb-bench

@linux-aarhus

I really need to take some time and implement some kind of off-switch

udev-usb-sync {disable|enable}

That might be a good idea.

Sure thing - thank you for your help

Waiting for final sync (actually writing data to the drive)...

With the udev-usb-sync settings only 33MiB is ever written.

This matches my current observations - with the adjusted numbers - only 33MiB is ever written to the target.

Since it work perfect on kernel 6.18 and 6.19 - it has to be a change in how the kernel responds - but I am not smart enough to see what - and to be honest - I have other things on my mind - so the help you provide with this is precious to me.

Just to say on linux 18, I did not expect any thing to happen, but after a reboot the speed of copying went from 33 Mb/s to 74 Mb/s

Apologies for the delay in replying. Last night was the first decent night’s sleep I’ve had since an eye surgery ten days ago. Got in a solid 12 hours! Not for the squeamish: Vitrectomy - Wikipedia Had the “pars plana” variety.

Performed daily update on the unstable-branch laptop. Booted to 6.19 and performed test. It went so fast with the 131.5 MiB file I had been using, I couldn’t get Dolphin’s notification window open fast enough. Switched to a Manjaro ISO as the test file. Resulting screenshot:

Rebooted to 7.0, now RC7:

Note too that I’ve pinned open the notification from Disks & Devices to show current capacity of the flash drive.

While still under RC7:

dd if=/dev/urandom of="/run/media/brucew/Ventoy-C/testfile" bs=1M count=50 oflag=append,direct conv=notrunc                                      ✔ 
50+0 records in
50+0 records out
52428800 bytes (52 MB, 50 MiB) copied, 0.951596 s, 55.1 MB/s

I’m with @linux-aarhus thinking it’s a kernel thing. A change I noticed while writing this is that nomacs (image viewer) no longer launches. (It was fine under RC6 and before any other updates this AM.) Had to use gwenview instead. Have yet to look into that.

HTH! (And thank you for your work on this!)

@brucew

A change I noticed while writing this is that nomacs (image viewer) no longer launches.

As it is an AUR package, did you rebuild nomacs after the update? I just successfully built and opened it on my Testing branch system, which is currently on the same version of qt6 as Unstable branch and is running the RC7 version of linux70.

Not a bad little image viewer, although I think I’ll stick with qimgv-git as my main picture browsing and basic editing (cropping, resizing) tool. I’ve been using qimgv-git happily for several years.

[brucew]

@scotty65

did you rebuild nomacs after the update

Thanks for the reminder, Scotty. I’d forgotten I hadn’t followed-up on that.

[Yochanan]

Another reminder:

@Yochanan

AUR (Arch User Repository) packages are neither supported by Arch nor Manjaro. Posts about them in Announcements topics are off-topic and will be flagged, moved or removed without warning.

For help with AUR packages, please create a new topic in Support > AUR and a helpful volunteer may be able to assist you.

[GaVenga]

ARCH has Gnome 50 in testing since 04. April 2026…

[Yochanan]

GNOME 50 packages are live!

Make sure you see manjaro-gnome-settings 20260221-2 before updating and rebooting.

Note that not all extensions have been updated yet.

Confirmed issue with Space Bar:

[GNOME 50] Left click on Workspace shows menu, like left button clicked

EDIT: Resolved and gnome-shell-extension-space-bar 36-1 is now available.

[Hanzel]

After updating and rebooting the dbus-broker seems confused, lost of lines with duplicate name errors eg:

dbus-broker-launch[935]: Ignoring duplicate name ‘ca.desrt.dconf-editor’ in service file ‘/usr/share//dbus-1/services/ca.desrt.dconf-editor.service’`

The service file is unique in the system, the service file does not contain a duplicate name.

$ cat /usr/share//dbus-1/services/ca.desrt.dconf-editor.service
[D-BUS Service]
Name=ca.desrt.dconf-editor
Exec=/usr/bin/dconf-editor --gapplication-service

So far this does not seem to break anything and is a warning but reported as an error. So far no clue if this is an system issue on my side or something else, hence posting this.

Edit: some searching leads to an issue on the gdm repo that seems like the behavior I experience.

GDM sets duplicated XDG_DATA_DIRS entries ("/usr/share" and "/usr/share/")...

[Yochanan]

That’s just a warning and can be ignored. This is reported in the journal:

Subject: Invalid service file
░░ Defined-By: dbus-broker
░░ Support: https://groups.google.com/forum/#!forum/bus1-devel
░░ 
░░ A service file is a ini-type configuration file.
░░ 
░░ It has one required section
░░ named [D-BUS Service]. The section contains the required key 'Name', which
░░ must be a valid D-Bus name that is unique across all service files. It also
░░ contains at least one of the two optional keys 'SystemdService' and 'Exec',
░░ as well as optionally the key 'User'. Exec must be a valid shell command and
░░ User must be a valid user on the system.
░░ 
░░ A service file should be named after the D-Bus name it configures. That is
░░ a file containing Name=org.foo.bar1 should be named org.foo.bar1.service.
░░ For backwards compatibility, we only warn when files do not follow this
░░ convention when run as a user bus. The system bus considers this an error
░░ and ignores the service file.

Upgrading to kernel 7.0 Message:
7.0.0rc7-1 IS NEWER than 7.0-1

Loading manually from mirror and installing, Message: downgrading 7.0.0rc7-1 TO 7.0-1
After rebooting the newer kernel 7.0.0-1 is the current one;
the RC does not exist in repos any longer.

[Pille]

@GaVenga

downgrading 7.0.0rc7-1 TO 7.0-1
After rebooting the newer kernel 7.0.0-1

What now? 7.0.1 or 7.0.0-1 ?

[philm]

7.0.0rcX is newer than 7.0. A possible fix can be to change the version to 7.0.0, which is higher than 7.0.0rcX.

[Pille]

There seem to be a mismatch.
I’ve installed the one which is documented as “7.0.1” in via Manjaro Settings Manager, but after reboot the system is on 7.0.0.1
Maybe that somewhat confusing

[dmt]

That would be 7.0-1 and 7.0.0-1 notice the - is not a .

[Pille]

Evidence for me got get my glasses cleaned
Thanks for it
