Solution #79 solves the issue for me too. Ubuntu 17.10. I was trying to copy some big files in the order of 50GB to an external hd (formatted NTFS) via USB2 and noted it hung every time (I tried at least a whole afternoon). I installed caja and had the same issue like under nautilus. I have never seen this bug before although I use a lot external disks with big file transfers
Setting /proc/sys/vm/dirty_bytes to something like 200000000 (circa 200 MB) solves the problem. The original value in that file was 0. As stated in the thread that value is too small and can cause freezes of the OS. I tried a value of 15 MB too and had freezes. The only problem now is that the value in dirty_bytes is set to 0 every boot. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/1208993 Title: Ubuntu slows down and hangs while copying file from/to USB To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1208993/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
