CPU @ 100% LXDE

[Dart]

Just installed LXDE - I hear my system running like I never heard it before. In windows is quiet cpu is mostly low. However when I boot into pclos lxde, the cpu is always between 89 and 100% constantly ... all other items are showing 1% to 3% max. X root = 95%


I have added nothing to the system other than ran updates from synaptic after first install.

Would you please post your system specs? would be easier for people here to try to help you

I have a similar issue here in LXDE but related to a different case.

I noticed that if I kill X in top or logout by Ctrl+Alt+BackSpace(push fast twice) after I login back X is taking the usual 1-3%.

[Dart]

ctrl-alt-backspace did work - i just migrated from pclos gnome for having to continualy do the ctrl-alt-backpace routine to get some issues resolved upon initial login - could not really get any useable advice on how to resolve it. at least this lxde version seems less buggy in my case (except issues with themes)

what causes this - any fix ?

thanks for the suggestion unclev  

[uncleV]

After I reboot X takes >95% again so it's a temporal solution (till next reboot).
I'm trying to find out the cause here but it is not necessarily it would be the same for you

[vjeko]

regardless the reason, have you checked using task manager/system monitor what process exactly is causing the cpu to get crazy on steroids?

that would be a start for me, since i had the issue with bluetooth modules, even if the switch is off, they tend to go wild, so i just kill the process, and it gets to usual usage baseline.

you can sort any column, so its wuite easy to find and sort stuff out/get whats going up and down and for how much

Dart,

Can you open a Terminal and post the result of the following lines (note case sensitivity)

lspci |grep VGA

and

cat /etc/X11/xorg.conf |grep Driver 

I would also strongly suggest ensuring that the install is fully up to date via synaptic and install the latest kernel (as you have a sempron 3100 - which is K8 arch iirc - I would suggest the .a64 kernel) 

Other things to check are in PCC>System>services - make sure that cpufreq and powernowd are running

Hope this helps

Post back with that information

Hi,

Do you have htop installed ? If not, you could install it, run it in console (root or user, as needed) and will be able to filter the cpu use (or other resource items as needed).

Hit F6 for "sort by", then in the left column you can select cpu, memory and other things.

top and the other monitoring tools give the app and it is X here. No other app taking abnormal cpu resources.
When I kill X at login page by Ctrl+Alt+BackSpace or after the login the situation becomes normal.
Look here for details please:
