10 minutes ago I was just surfing the web as usual on my Ubuntu 10.04, when all of a sudden the system became slow. I realized that the CPU usage is 99%. I opened System monitor and everything seemed fine. I couldn't see any process that used a lot of CPU. I logged out and logged in, and CPU usage was still 99%. Then I rebooted and now everything is ok.

What happened and why couldn't I see the process that used so much CPU? What to do if that happens again? I want to solve the problem, not to reboot every time that happens.

Here it is again. It's because of Gparted. Everything worked fine until I started it. And now it's 99% again. I closed Gparted and still 99%. I can't find gparted process. Here is the "top" output

Now I logged out and logged in and CPU usage is normal. I started Gparted and this time everything is ok. I am very confused

I installed Cinnamon on my Ubuntu 12.04, and it works well, but sometimes it just freezes for no reason. I can move my mouse but can't click on anything.

So I want to restart Cinnamon from tty, like I used to do with gnome shell. How do I do that?

I tried killall cinnamon and nothing happened.

Then I tried export DISPLAY=:0.0 , cinnamon --replace and still nothing.

I guess the command cinnamon is not valid. I don't want to restart the whole X server because then all of my windows will get closed. I just want to restart the window manager cause I believe it is causing the problem.

I have spell check enabled for the english keyboard, but when I use serbian cyrillic keyboard, I want that feature turned off, because then all the words get underlined like i spelled them wrong

How do I do this? Thanks

Somehow now it works just as I want in Firefox, but in Empathy it still marks all the Cyrillic words, and I just want it to mark misspelled English words

Here's an example

  • Firefox (good):

Firefox

  • Empathy (bad):

When Firefox starts, it creates two files in the user settings directory: places.sqlite-shm and places.sqlite-wal and deletes them upon exit.

Just for the experiment, I set the permissions of those files so that only root can read/write them. But when I closed Firefox, those files got deleted! How is that possible? Firefox is not running with root permissions...

Don't ask me why I'm doing this, I'm just curious
