Mouse CPU System Monitor
 

Hi

I am using Ubuntu 10.04, having a lot of problems, have loaded the operating system three times now.

The mouse icon keeps freezing, the CPU on system monitor is showing 100% most of the time that is when the mouse sticks.

The hardware is fine, it only sticks when CPU shows 100%.

Processes on system monitor is showing all is sleeping.

There is no programs activated your server or desktop sharing.

Normally I have had up to five activities going on at the same time even video editing without the machine freezing or mouse delaying positioning on screen.


Thanks EAI

Open a terminal and run top. When the machine freezes, you will see what is using all the cpu.

100% cpu
 

Hi

All other versions of Ubuntu I have used are hardly a drain on the cpu even with programs open, its the spiking on the cpu that slows down the operating system.

Even video editing uses 100% of cpu speed but dose not impair the pc, but now it dose for no reason even when there is no programs opened.

This is what terminal produced.

Thanks EAI

Hi

Thanks for that command for terminal.

I ran Top and discovered it is a command called "phy0" that comes up for no reason, it appears for about a second or so then dissapears just to return, enough to mess up fuctions on the pc.


Thanks EAI
