Ubuntu MATE heats my laptop.
I cannot find out why.
By heats my laptop I mean:
- Laptop is noisy
- there is hot air from CPU cooler
- the aluminium case is little bit warm (on top of the cooler)
- the cpu temperature is ok, and case temperature too (but I don't like noise and whatever)
On literarilly every other operating system the behaviour is different:
- laptop is quiet
- there is COLD air from CPU cooler
- the aluminium case is cold, you could say it is chilly (on top of the of cooler)
- the cpu temperature is ok, and case temperature too AND THERE IS NO NOISE
By every other system which works ok for me I mean:
Ubuntu based:
-Ubuntu 22.04, 22.10
-Xubuntu 22.04, 23.04
Mate systems:
- Debian with MATE .iso
- Siduction with MATE testing .iso
- Linux Mint Mate
- Solus MATE
- Manjaro Community MATE (my main choice Manjaro 22.1)
- EndeavourOS with MATE
- Fedora MATE+Compiz spin
- !!! Older edition of Ubuntu MATE (but don't remember exactly which but older than 22.04)
The only other system which heats my laptop is MX Linux (which really heats it, cpu temperature numbers are not ok)
I tried Ubuntu MATE in 3 ways and Ubuntu MATE heats up in all 3 cases
- Installed Xubuntu 23.04, then installed
apt install ubuntu-mate-desktop
and rebooted to MATE - Installed Ubuntu MATE 23.04
- Installed Ubuntu MATE 22.04.2
In all 3 cases Ubuntu MATE heated my PC
I tried to disable compositor so:
- In Settings >
Windows
disabled software compositing - In
Mate Tweak
chose to useMarco without compositor
observed that MATE heats up little bit less...
BUT STILL heats up
Then I disabled mate-power-manager
from Startup Applications
and restarted...
in this case it is a win, cause laptop doesn't heat up when idle(by idle I mean using only Aisleriot to play a game and nothing else)
Also it is a win, cause browsing with firefox without watching background videos doesn't heat up my laptop.
but when browsing (by browsing I mean watching a video 1080p fullhd in Firefox Snap and browsing the net)
it still heats up
with disabled compositor and mate power manager my pc is still:
- noisy
- there is still hot air
- the aluminium case is cold, but not chilly (on top of cooler)
- the cpu temperature is ok, and case temperature too (but I don't like noise and whatever)
Mate System Monitor shows that there are only 3 apps which eat PC:
- mate system monitor
- firefox containers
- Xorg -> which constantly eats cpu (up to 20% at times)
? So my question is how Ubuntu MATE is configuring MATE ?
? And how to configure MATE myself so it works like in any other distro ?
p.s:
I use a laptop from 2015 with discrete GPU
- Intel core i5 broadwell
- AMD southern islands gpu R7
