Bug#1119949: plasma-systemmonitor: gpu monitoring pie chart not working always show 0 but in Fedora 43 it works fine

[diylinuxuser <diylinuxuser@pm.me>]

Hi Aurélien,

It works turn out it's the "syntax" error and I set both CAP_SYS_ADMIN as well as CAP_PERFMON and reboot and now the pie chart showing the value correctly.

sudo setcap 'CAP_SYS_ADMIN=+ep' /usr/lib/x86_64-linux-gnu/libexec/ksystemstats_intel_helper

sudo setcap 'CAP_PERFMON=+ep' /usr/lib/x86_64-linux-gnu/libexec/ksystemstats_intel_helper

Thank you so much!
Best Regards,
David
