Dear All, I downloaded KDE recently and it was working fine for few hours and then slow down.
I check and found few things : 1. - intel_powerclamp - intel_rapl - intel_rapl_perf - x86_pkh_temp_thermal I removed from module loading list and I can see some improvements. 2. I try to remove nouveau graphics and intent to use i915 Intel default chipset, I am not able to remove. 3. Few times, I see following message : perf interrupt took too long (3181 > 2500), lowering kernel.perf_event_max_sample_rate to 50000 After see this message, computer slow down for few mins. Please advise on how to solve above issues. Regards Srinivasan
