Linux Mint Forums

my linux mint system keeps crashing too often and i am not happy with it here is a screen shot

kactivitymanagerd probably is for your plasma activities. So some ideas;
- Have you done a clean install of Linux Mint 14, or did you upgrade in place from an older version of Linux Mint? (Or convert an exisiting Ubuntu installation.) That might have result in some of your KDE configuration files causing problems now.
- Which version of KDE are you using? The default, or have you upgraded to 4.10? If you haven't upgraded, you might consider doing that: http://forums.linuxmint.com/viewtopic.p ... 12#p684113. The newer version might fix whatever problem you are now having with your plasma activities.

i have done a upgrade and a conversion to ubuntu

Probably something is causing problems in the activity manager configuration. You may try the following to reset your activity manager configuration to its default values.

1. If you don't use activities, just delete the current configuration: Else, if you do use activities, let's just move this folder somewhere so you can recover it later if needed: 2. Log out and log back in. This will create the default configuration for activity manager in ~/.kde/share/apps/activitymanager.

Hopefully that fixes your problem.
