I don't know, it makes me think that the initial splashscreen is managed by wayland and then when switching to plasma x-11, which in Solus doesn't have optimus, it has to use only nvidia without using the intell iGPU the system will break (because wayland instead somehow manages both GPUs), but it's just a non-technical hypothesis. Maybe I was wrong about Optimus...

Created attachment 186837 [details] btop-CPU-GPU usage SUMMARY The system use too mace resurce of cpu and gpu for anytings, but in particular for video on x11 STEPS TO REPRODUCE 1. Start PC 2. In the splash screen choose Plasma X11 (instead of wayland) 3. Open dolphyn 4 Choose a video file (but it also works with audio files to a lesser extent). 5 Open it with a video player, such as mpv 6 The nootebook fans start OBSERVED RESULT The nootebook fans start. the output of top passa da ``` PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3364 fab 20 0 1552828 549100 317160 S 9,3 3,4 18:29.55 kwin_x11 3240 fab 20 0 24,9g 413024 343116 R 9,0 2,5 8:39.81 Xorg ``` a ``` PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 16349 fab 20 0 2941836 406624 268392 S 243,9 2,5 0:57.64 mpv 3364 fab 20 0 1569260 565120 333160 S 137,2 3,5 20:06.39 kwin_x11 3240 fab 20 0 24,9g 443820 372260 R 74,4 2,7 9:29.85 Xorg ``` EXPECTED RESULT to play video with a normal usage of resurce SOFTWARE/OS VERSIONS Linux/KDE Plasma: Solus/ 6.5.2 KDE Plasma Version: 6.5.2 KDE Frameworks Version: 6.19.0 Qt Version: 6.9.3 Kernel:6.16.12.323.current(64bit) ADDITIONAL INFORMATION I attach btop while I watch a video on YouTube with Firefox. ``` nvidia-smi Thu Nov 13 20:03:17 2025 +-----------------------------------------------------------------------------------------+ | NVIDIA-SMI 570.190 Driver Version: 570.190 CUDA Version: 12.8 | |-----------------------------------------+------------------------+----------------------+ | GPU Name Persistence-M | Bus-Id Disp.A | Volatile Uncorr.
