I'm new to Linux world and I have a problem with my fresh installation of Ubuntu 14.10 64-bit. My processor is Intel® Pentium(R) D CPU 2.80GHz × 2 with 4 GB of ram and GeForce 8600 GT/PCIe/SSE2. When I use PC CPU load is always above 0.90.
I found these questions but no luck at all with finding solution:
- High CPU usage even when no application is running(Desktop)
- Any way to check the clock speed of my processor?
- And more in google
Compiz are always first. For example while I'm moving Firefox window both go around 60% of CPU or when I open the search menu and typing random stuff.
In Unity Tweak Tool texture quality is on fast and all animations are disabled + blur under search windows is turned off, installing Unity 2D doesn't work.
I'm using the NVIDIA Binary Driver 331.38 and changing workspaces is very smooth just like scrolling pages is Firefox.
Also I disabled the hardware acceleration in Firefox and some of the plugins. I have right now turn on
Adblock Plus and
Flash - block.
I'm not sure but this can help:
sudo dmidecode -t processor | grep Speed Max Speed: 4000 MHz Current Speed: 2800 MHz
Also done this.
Copy and paste, or type, the following lines at the bottom of the
Option "RenderAccel" "True" Option "DisableGLXRootClipping" "True" Option "DamageEvents" "True" Option "UseEvents" "True"
Then I had to recover the
Xorg default settings, when I restarted PC window show up with something like:
You are running low graphics mode
but I fixed it so all is OK right now.
It's 5th day and I'm stuck, so I'm begging for help.
Also I installed
XFCE (Xubuntu 14.10) and
LXDE (Lubuntu 14.10) but I like Unity much more.
On Ubuntu 14.10 32-bit is even worse + here is my
top when PC on idle, all look good:
load average: 0.11, 0.21, 0.29
but PC is for work not idle.
So finally my question: is it normal? If not how can I fix my CPU usage? Why is
Compiz so resource hungry?
