Toshiba notebook with linux ubuntu freezes

scottyboy1979

I have a toshiba nb100 notebook with linux ubuntu........when i work offline everything seems to be ok...if a bit slow......the problem is when i switch the computer to it's online mode,when it becomes very slow and unresponsive,and all pages and messages on-screen will not close,this only seems to happen when online........i'm new to linux and have always used windows xp or vista prior to this,and i was hoping that someone would have an idea of how i can solve this problem....any help will be appreciated

What do you mean by "when I switch it to online mode"? Are you hitting a physical switch on the system or just using the network manager to connect to a network?

It's when i use the network manager to connect to a network,the whole system becomes very sluggish and doesn't respond and if it does it takes what seems an eternity

This is very weird, I have installed various version of Ubuntu on several computers and never seem a system stall from anything short of an application crash.

Exactly what version of Ubuntu are you using?
Was it pre-installed on the computer or did you install it yourself?
Have you run "top" in the terminal when this is happening to see what programs are using the most resources?

I'm using ubuntu 8.04(hardy).....it was already pre-installed when i bought it.......it's very slow and even the webcam is very slow and jerky.....i've run the "top" command in the terminal and this is what it said :

Well whatever it is the problem is because it is tying up massive amounts of memory, not cpu cycles.

It looks like the main culprits are osd, osdd, gnome-terminal and at-spi-registry. The humor it is osd is the biggest problem, but is is meant to manage shared memory. I think you may have some corrupt files on your system in regard to that program that are causing the issues. Rather than trying to fight through tracking the file(s) that are responsible and attempting to reinstall them I would recommend going to the update center and upgrading your system to Version 9.04, the version upgrades will cause all packages to be updated including the ones that may be causing your issues.

But you are running your system with only 512 of RAM, so performance will only get worse as more demanding applications are run. You may want to consider purchasing additional memory for the future.

Thanks for that i'll give it a go hopefully i'll get it sorted........thanks alot for your help,it's much appreciated

As applications and libraries are updated they usually address past issues including memory handling, hopefully after the upgrades you will see a noticeable increase in standard performance also.
