First time Lubuntu user!

[Yuvanesh]

Hey all,

This is my first installation of lubuntu, decided to build my own pc(first time too). After some time researching decided to go with lubuntu. Hoping you guys will be kind enough to help me .

system specs

amd a6-5400k cpu
gigabyte f2a75m-d3h
4gb ram
120gb ssd(primary)
3TB HDD(storage & media)1) After doing a clean install, the first problem i had was the graphics. Open source drivers caused tearing and lag, so i switched to proprietary drivers. There is still some minor lag when i drag a window around the screen. Is there any solution, or is this normal?

2) When i click on "sytem profiler & benchmark" 2 grey windows open and i have to close the smaller window 3 times before i can see system profile. Also the benchmark doesn't work? Picture attached.

3) I installed lm-sensors, but my temperature is shown incorrectly. I tried uninstalling/reinstalling but still the same.

4) how do i uninstall the default games , sudo apt-get remove "game name" ?

Any additional advice or recommendations would be much appreciated. I am really excited to be using linux, and i hope that in time i can minimize my usage of windows . Thank you for your time in advance.
