Code:

sudo apt-get install bootchart

Then you ofc reboot your machine

The boot chart image will appear in /var/log/bootchart/*.png with the username and host + the date as the file name.

You can safety remove bootchart after sharing the generated .png file with us to review, and see if something there is the cause of the slow down for you.

done that but it doesnt generate the png file. The bootchart folder is empty

After one or two reboots? And did you do it right away or wait a moment. It may have a slight delay in it's generation.

Indeed you do, I forgot about that package lol. Bit late for me, and on meds >.<


you also need that package mentioned. Sorry about that.

O.K, see if that helps TMG1961

strange..i did the folowing


Installed bootchart, installed pybootchartgui but the bootchart folder remains empty.
Did 3 restarts, even did shutdown the laptop completely and rebooted but still notting in bootchart folder.

Press F4 during boot to see the text boot. You should then see where it's pausing or taking longer.

I just installed and tested on one of my PC's, it took about 60secs to appear in the bootchart folder.

Finally got the bootchart.png file

Now just need to figure out how to show it here in a way that is is readable

I'm not an expert,
but it looks like you have a slow hard drive, and that is creating a lot, almost constant disk(I/O) activity.
I realise I have an SSD, but if you look at my graph, I have bursts of activity.

Whilst it appears to be insignificant you appear to have Teamviewer auto starting.

Are you connecting to any network shares automatically.??
There is a process gvfsd-smb-brows which seems to take a lot of CPU
Not sure why..??
If you are on WiFi, it maybe slow/struggling, Can you do a test on a Ethernet cable

Maybe somebody else can spot something else.
Try Googling some of the items that appear to take a long time, or use a lot of CPU

GL... Dave
