Thunar unresponsive when copying to USB


When I copy to or from USB sticks or my mobile phone that’s connected via USB, Thunar becomes unresponsive. I can’t open files anymore or browse through my hard drive. Copying is also very slow, but when it’s finished, everything is normal again.
However, I can use the computer normally (like internet browsing) while copying.

I found some older information about it from 2013 to around 2017. I think most user complained that the whole computer becomes unresponsive, so I’m not certain if it’s still the same issue. However, I ran these commands but sadly, it didn’t help and Thunar is still unusable as long as I copy files to USB.

Also the speed drops often to 50KB/s or less and it takes many hours to copy just a few Gigabytes.

same happens with me, so while copying I use pcmanfm. I still use thunar because I find it’s UI better than others.

I tried it and it works perfectly! I thought it’s a kernel issue, but it seems that Thunar is the issue? Let’s hope it will be fixed eventually…

There is a lot to like with Thunar but I don’t recognize the unresponsiveness.

My use case is not the usual though which makes me speculate in the Xfce integration with gfvs - which Thunar makes use of to mount removable and network devices.
