[SOLVED] USB storage devices are detected only once per session in plasma5 sytem tray

sairum · 09-16-2021, 11:22 AM

This is a behaviour that appeared after last week's upgrades, but I'm not sure which. I'm running -current64 multilib. After starting X from runlevel 3, plasma detects any USB storage device the first time I insert it in any USB port (see corresponding dmesg output)

USB stick inserted

Code:

Unplug USB stick

Plug it again in same USB port

Wait a few seconds. No dialog popup in system tray. It's still possible to mount USB disk manually in bash ("mount -t auto ...") or by clicking in the appropriate option in Dolphin's "Removable Devices" left side bar. USB stick mounted using Dolphin's "Removable Devices" option in left side bar.

A different USB stick in a different port summons the popup in system tray again!

Code:

But it fails to the second time the device is re-plugged.

This is obviously a KDE (plasma5) thing. Creating a new user account with a fresh new plasma configuration does not solve the problem. I suspect this has something to do with the interaction between KDE and device mounting rules. Is anyone experiencing the same problem? I know at least one person also using -current that does. Actually he warmed me right away, but I only updated my -current installation yesterday.

Fixed in plasma 5.23

until then, here is the workaround

Merci! This seems to solve the problem!

You should propose this workaround to be merged to the current build of Plasma5, because I understand that Plasma 5.23 will not be available on Slackware 15.0, but on the next development cycle.

I think is quite probably that Slackware 15.0 will ship Plasma 5.22.5

This workaround has already been proposed in "All Things KDE5/Plasma for Slackware Users." by the author himself (Fabio)
And I'm pretty sure M. Volkerding has seen it

Maybe I'm wrong, but as far as I remember, he never (or as an exception) touches the upstream code.
And there must be prabably a lot of reasons why KDE devs didn't put it in the 5.22.5 patch set

But this patch is just some config files and you don't need to compile again anything.

I have tested those 3 config files in a new latest Slackware current I have put on an old machine I have reinstalled from scratch and which had the KDE5 bug with USB sticks.

With those files, all is working again. All you have to do is to put them on the right place. They could be put in the package easily.

This bug is annoying. For me being able to load USB devices quickly is important for non geek users or even for geeks.

I agree a thousand times
But I'm not the one to say that to :-)

I for one, I copied the files and I'm fine with that
If someone wants to make the report, go on

Patch applied :

Code:

kde/plasma-workspace-5.22.5-x86_64-2.txz:  Rebuilt.
  Patched to fix USB storage devices detected only once per session.
  Thanks to ctrlaltca.
