Yeap it helps and it is quite clear.
Still another remark. Sorry for going on with the digression here.
If there is a more proper channel we can move there.
In my old laptop when I load it with a single thread application I get
TURBO ENABLED on 2 Cores, Hyper Threading ON
Max Frequency without considering Turbo 1894.72 MHz (99.72 x [19])
Max TURBO Multiplier (if Enabled) with 1/2/3/4 Cores is 27x/25x/25x/25x
Real Current Frequency 2663.14 MHz [99.72 x 26.71] (Max of below)
Core [core-id] :Actual Freq (Mult.) C0% Halt(C1)% C3 % C6 %
C7 % Temp VCore
Core 1 [0]: 2663.14 (26.71x) 99.3 0 0 0
0 58 0.9207
Core 2 [2]: 2492.89 (25.00x) 4.8 5.78 1 1
85.6 55 0.9207
Now the remarkable difference is that the second core spends 86% of the time in
C7 state.
On the other hand in the new laptop all cores stay in C1 state most of the time.
Same happens without load (see previous post for data on new laptop).
TURBO ENABLED on 2 Cores, Hyper Threading ON
Max Frequency without considering Turbo 1894.72 MHz (99.72 x [19])
Max TURBO Multiplier (if Enabled) with 1/2/3/4 Cores is 27x/25x/25x/25x
Real Current Frequency 1111.72 MHz [99.72 x 11.15] (Max of below)
Core [core-id] :Actual Freq (Mult.) C0% Halt(C1)% C3 % C6 %
C7 % Temp VCore
Core 1 [0]: 1019.47 (10.22x) 11.9 9.92 1 0
82.3 46 0.7955
Core 2 [2]: 1111.72 (11.15x) 12 16.1 1 0
75.5 50 0.7955
In both cases the driver is the intel_pstate and n boh case I'm monitoring with
i7z, sudo and 1 sec freq
Old processor is Intel Core i5-3337U
New processor is Intel Core i7-8750H

Title:
Ubuntu 18.04 is overheating after upgrade from 16.04
Status in linux package in Ubuntu:
Confirmed
Status in xserver-xorg-video-nouveau package in Ubuntu:
Confirmed
Bug description:
Ubuntu is overheating at my laptop. Opening youtube on firefox is
enough for critical temperature shutdown.
Using lm-sensors for monitoring on 18.04 the temp varies between 70 and 85°C
with only firefox or chrome open and doing nothing.
On my old 16.04 with same using, the temp varies between 55 and 70°C.
First thought was the driver nouveau is the problem, and finally I was
able to install by add "nouveau.modeset=0" at livecd boot options,
without temp shutdown.
After install I disable the nouveau at modprobe blacklist, but the
system continues overheating and shutdown with basic usage.
I have no idea what's happening with the bionic at my laptop.
My laptop is a Samsung RF411 i5 2nd Generation and Geforce 540M.
