Operating System: Fedora Linux 41 KDE Plasma Version: 6.3.80 KDE Frameworks Version: 6.12.0 Qt Version: 6.8.2 Kernel Version: 6.13.3-201.fc41.x86_64 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 PRO 7840U w/ Radeon 780M Graphics Memory: 58,5 GiB of RAM Graphics Processor: AMD Radeon 780M Manufacturer: LENOVO Product Name: 21K5000JGE System Version: ThinkPad P14s Gen 4 Works as expected for me with: - 2020 Lenovo ThinkPad X1 Yoga gen 4 - 2024 HP Pavilion 14 plus Both when alone, or connected to an external keyboard. I'm also not able to reproduce on git-master on a Lenovo Flex, which has an AMD Ryzen processor and AMD integrated GPU I tested with the built-in keyboard I also cannot reproduce on Debian 13 (Trixie) - unstable repository, with: SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Plasma Version: 6.3.0 KDE Frameworks Version: 6.11.0 Qt Version: 6.7.2 Kernel Version: 6.12.16-amd64 (64-bit) Mesa Version: 25.0.0-1 Graphics Platform: Wayland HARDWARE SPECIFICATIONS Hardware: Laptop Dell Inspiron 5770 (17" 1080p@60Hz screen) CPU: Intel® Core™ i5-8250U CPU @ 1.60GHz GPU 1: Mesa Intel® UHD Graphics 620 (main, Vulkan capable) GPU 2: AMD Radeon R5 M465 Series RAM: 8 GiB (7.7 GiB usable) Tested just with the built-in keyboard too. well, this is currently a problem with this specific laptop - even without any attachments (keyboard or thunderbolt devices) Just changing the brightness with Fn-F5/6 e.g. running on batteries has effect only after this 20sec delay. Setting other Fn-Fxx keys with global hotkey functions do work immediately I can also confirm that other laptops (t470p/intel+nvidia or old t420/intel only) don't have this problem. Any logs i can provide? It woulds like this may be a hardware, firmware, or driver problem on that machine. It sounds like this may be a hardware, firmware, or driver problem on that machine. there was a firmware upgrade for the p14s in the meantime, so i'm up-to-date now still no change to the behaviour. (ext. keyboard FN-changes as well as brightness slider for the laptop-display update the brightness instantly) Still happening in Plasma 6.4.4? Operating System: Fedora Linux 42 KDE Plasma Version: 6.4.80 KDE Frameworks Version: 6.18.0 Qt Version: 6.9.1 Kernel Version: 6.15.10-200.fc42.x86_64 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 PRO 7840U w/ Radeon 780M Graphics Memory: 64 GiB of RAM (58.5 GiB usable) Graphics Processor: AMD Radeon 780M Graphics newest firmware, current 6.5-dev updates... yes, it's still happening. The audio-function keys on the laptop (fn-f1/f2/f3/f4) work instantly, the brightness-controls (fn-f5/f6) only with a long delay |
