Extremely slow system

[larbac]

Hi

I have updated my laptop to 10.10.
No problems with the updates, bu after reboot the system runs extremely slow.

The Launch K and all the bar doesn't work. The cpu cooler is working at full speed...

I can only execute browser and other things using ALT+F2.

What can it be?
Thanks

Hmmm I don't know about your issues with the k menu and the bar.

does ctrl+esc indicate that there is a process hogging your cpu?

Re: Extremely slow system

I think have the same problem.

Starting of details:
lspci | grep nvidia
01:00.0 VGA compatible controller: nVidia Corporation G72M [Quadro NVS 110M/GeForce Go 7300] (rev a1)
nvidia-smi Timestamp: Wed Oct 13 08:39:53 2010; Driver Version: 260.19.06
KDE 4.5.1
Linux goociolap 2.6.35-22-generic #34-Ubuntu SMP Sun Oct 10 09:24:00 UTC 2010 i686 GNU/Linux

and the rest:
I have a very poor performance of the KDE env. Very high CPU usage on a process of kwin (about 30-40 percent).. BUT...! When I disable "desktop effects", everything works super fast - as it should.
I suppose that the problem is the nvidia drivers, or something at the interface between the driver / library of desktop effects.

Re: Extremely slow system

Something like that can happen when you upgrade kde so if your upgrade took you up a version of KDE it can be worth renaming /home/.kde/share/config.

It will reset your desktop which you will need to reconfigure but it might be worth a shot.

Run Alt-F2 "konsole" with no quote marks to open the Konsole, aka terminal. In the terminal, run

htop

and this will show the running processes, in descending order of resource consumption.

There was a kernel update last evening -- make sure your system is updated.

Nvidia driver 260.19.06 is running well on my GTX260, but it is a beta driver. You might want to go back and try the official released driver, just in case that is the issue.

Yep.
I had the same or similar issues when "jumping" from one version of KDE4.x to another.

some times panels, widgets and activities overlap each other.

The complicated way:
First make sure that desktop effects are turned off.

Then delete the panel at the bottom with:
right click on desktop->unlock widgets if they are locked.

Right click on the bottom panel and choose remove panel.

Now get rid of all the widgets by mouse over -> click on the "X" that appears in the sliding configuration panel.

Finally delete all activities except for one.

Log out / log in and you should a virgin desktop.
If needed you can now add a new default panel with:
right click desktop->add panel->default panel.

Add your widgets as needed.

The less complicated method:
open a terminal or do alt+f2 and type:

sudo stop kdm

Now do what the liquidator suggested:

mv /home/yourusername/.kde/share/config /home/yourusername/.kde/share/configOld

Now restart kwin:

sudo restart kdm

I hope that helps

Re: Extremely slow system

Solved.

The problem was really the .kde config folder. After renaming, start to work normal now.

Thank You.
