Re : Slowness in Graphics display

[Srinivasan T <tsvs.lc@xxxxxxxxx>]

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
