Re: HELP NEEDED!!!!
To see if anything is hogging resources, and slowing everything else down, you can do a couple of things:
Hit ctrl+esc which will start the kde system monitor. that will list all the processes that are running and the resources they are using. Right clicking on a process will give you the opportunity to kill it. I'd avoid that one until you know what the process in question does.
Another option is to open a terminal and type
That will launch a system monitor in the terminal. As it is run at a lower level it might be more accurate. Generally one possible culprit is is a process called akonadi. Whether you need it running or not depends on the applications you are running as there are a number of apps that need it to run before the will function properly.
Your question about grub is really more about Kernels to be honest. When by way of update you pick up a new kernel the system updates grub and you can boot into any of the kernels you have available. This can be useful because a new kernel version might not play too nicely with something on your system. You would not be the first to download a new kernel and find your machine won't boot. However because the old ones are retained, you have a failsafe, because you can choose the one to use.
Updates to existing kernels can also cause problems (although I can't recall having one) so it's sensible to have 2 kernels installed - the latest available and an earlier one that is known to work - that one is unlikely to be further updated. You can get rid of the others. Decide the 2 you need to keep. Do it with synaptic. Type kernel in the search box and look for those with a green box that shows they are installed. Mark for removal (right click) packages for the version you want to remove then click apply. Unwanted kernels will then be removed. Grub will automatically be updated when the job is finished so in reboot the grub list will be thinned. If it isn't then you have left a stray package and will need to remove it.
