SUMMARY When i "de-minimise" dolphin clicking on the task-manager panel, it will not appear for different seconds, AND will also freeze the "task-manager" STEPS TO REPRODUCE 1. set a secondary hard disk to go sleep after some minute with sudo hdparm -S 1 /dev/sda (where 1 should be 5 minutes) 2. make sure the disk is mounted, i use fstab 3. wait for the disk to go sleep 4. open dolphin, all should be fine 5. minimize dolpin, all should be fine 6. click on dolphin on the task-manager to maximize, it will hang until the disk restart (you can hear it spinning if mechanical) OBSERVED RESULT - dolphin not only does not open immediately - the disk in wake up unnecessarily - panel bar with task manager hangs until dolphin open EXPECTED RESULT - dolphin open immediately - disk is not access unless clicking on the device - dolphin should not hang other components SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.22.4 KDE Frameworks Version: 5.85.0 Qt Version: 5.15.2 Kernel Version: 5.13.10-arch1-1 (64-bit) Graphics Platform: X11 Processors: 12 × AMD Ryzen 5 3600 6-Core Processor Memory: 15.6 GiB of RAM Graphics Processor: AMD Radeon RX 5700 XT
I don't think the problem has necessarily anything to do with the maximizing of the window, rather when you interact with Dolphin in any way, it'll register it as url changed, which prompts kio to search for possible mount points. This in order checks your fstab and proceeds to wake up the devices in your /etc/fstab. Here's a merge request that had some work done a year ago, but didn't really get finished. I believe we're talking about the same issue: https://invent.kde.org/frameworks/kio/-/merge_requests/604 I'd really like to see this issue fixed, as my external drives wake up probably five times a day unnecessarily when I'm not even trying to access them.
