I've just installed ubuntu 16.04LTS and my laptop is taking too much time to start I have HP laptop, Intel coreI3 processor 4gb ram NVIDIA graphics card, and while opening 2-3 applications, it is lagging, is my RAM not getting used?
RAM may be not getting used, not sure help me fix it, Thank you for your time
To investigate the cause of the boot duration, please create a boot chart.
For the slow graphics performance you should install Nvidia's proprietary graphics drivers from the Additional Drivers application.
Your RAM is definitely being used. A lack of RAM may lead to performance issue but 4 GiB should be plenty. If you're still concerned look at the output of:
LC_MESSAGES=C free -h
The value in the line labelled “Mem” and the column labelled “free” should be quite low (< 1 GiB) if you have been using your computer for a few hours. If it isn't, that just means that your usage doesn't require that much memory.
