I reverted to Kernel to 5.3.18 ... also installed xserver-xorg-video-intel. strace for gnome-shell shows no more errors on mouse / touchpad activity and load remains low .. rahul@desktophp:~$ sudo strace -c -p 11997 [sudo] password for rahul: strace: Process 11997 attached ^Cstrace: Process 11997 detached % time seconds usecs/call calls errors syscall ------ ----------- ----------- --------- --------- ---------------- 40.36 0.041780 4 8944 7555 recvmsg 29.46 0.030497 8 3392 poll 10.36 0.010722 5 2064 write 9.19 0.009510 8 1091 ioctl 6.51 0.006742 5 1236 writev 3.06 0.003163 5 533 getpid 1.00 0.001038 1 770 read 0.02 0.000023 2 10 munmap 0.02 0.000018 0 48 34 stat 0.01 0.000013 0 66 mprotect 0.01 0.000013 13 1 restart_syscall 0.00 0.000000 0 1 close 0.00 0.000000 0 2 fstat 0.00 0.000000 0 2 rt_sigprocmask 0.00 0.000000 0 1 clone 0.00 0.000000 0 1 fcntl 0.00 0.000000 0 2 getrusage 0.00 0.000000 0 31 2 futex 0.00 0.000000 0 1 openat ------ ----------- ----------- --------- --------- ---------------- 100.00 0.103519 18196 7591 total top command log is attached .. it appears that the cause may be in broken Kernel drivers for intel chipset ..
