Desktop sluggish with kernel 2.6.24-12

[NickNak]

I have found that when using kernel 2.6.24-12 (installed by Hardy Heron beta upgrade), the desktop responds very sluggishly at times -- the mouse movement is jerky, menus open slowly, etc. -- and it seems worst when lots of disk chattering is going on. This is especially noticeable during login when lots of disk activity takes place. If I select kernel 2.6.22-14 at boot-up then this effect is not apparent.

You are not alone - I did a clean install of HH beta and I see the same result.

When I open a terminal window it takes about a minute before the shell prompt is ready.

As soon as you get logged in, open the Konsole and run
top and observe which processes are using the most resources. It may be that an unneeded process (like strigi daemon) is being launched at startup, and you can disable it. I have not noticed such behavior with my updated-from-Alpha HH system.

Same here Dibl. I haven't noticed that problem. I have in the past had problems with Strigi being a hog. I disabled it and hadn't had issue since and same as now on HH.

top shows pretty much the same thing with kernel 2.6.22-14 as with 2.6.24-12 but the responsiveness with the two kernels is very different. I don't think its a cpu load problem. (BTW: I'm not running strigi)

Maybe some ideas for you here:

In the end I found that when I moved the disk containing the kubuntu installation from the second to the first IDE channel both kernels were equally responsive.
