Hey there. I bought a little used nokia n900 for couple of days ago and it was alot of stuff on it when i had it but everything worked fine and the browser was doing a great job. I restored my phone to original mode and after that i put 10 gb of music, i installed debian and openoffice aps and i packed my desktop with some shortcuts and of course downloaded some apps and now it is a bit slower. For example in the begining i could watch live stream football match on my browser and it worked fine but now it lagges and are really slow.
How can i fix this?

Well, if you are confident enough with technology and Linux you can try over-clocking. If you aren't, remove some programs you don't need.

Sounds like a memory leak caused by one of your apps/widgets. Try the top command in Xterminal (or download Conky) to see what your highest CPU usage is coming from. Alternatively, remove widgets/apps one by one until you find the culprit.

thank you for the comments

thank you for the comments but i´m not comfortable with overlclocking it.

okey but how can i see what is normal in the top command and also in the conky app?

Same here!!!

The top-command shows what your most resource-consuming processes are. If there is some program that is consuming too much CPU or RAM you should remove the application or ask for help with it.

In my experience, nothing should take up more than 5% of your CPU in idle (except for that damn modest client :P) I forgot about Htop too -- I find it to be useful for this purpose.

Btw people, don't forget the thanks button

one more question, for example i have none application open and then i go to xterminal and see some application running, how can i close them through xterminal?, and is safe to close most of the applications/servers like for example Xorg or hildon-desktop? I really appreciate your quick answer i´m really happy with my nokia n900 and the maemo community to help me to get deep into it
