[MATE] Somethings here are not working

[Candelabrus]

Hi all, is my first post on this forum then ask license to all, allowed to join the community

Okay, let the problems

1- inside the Control Center, not all settings but some like to change themes, change the TrueType fonts and enable/disable composite need to restart the computer for the settings to take effect.

What could it be?

2- Frequency CPU Monitor from Mate Applets are not working, i can add it normally on the panel, but the frequency shown is always the same (800mhz) never changes.

3- In a past installation I had done work but this clean install I did the mate-applet-sensors is not detecting the nvcontrol nor the hddtemp.

When I type emerge -av mate-sensors-applet it shows it will to add nvidia flag as hddtemp and in time of compiling it does not compile.

Thank you all and hope you can help me
