I had ubuntu 16.04 installed in my device. A few days ago I tried to install lubuntu on my device . However, something went wrong.Probably It was not installed properly. Now, when I start my laptop , it shows lubuntu icon first, and then it shows the line : /dev/sda6 : clean, xxxxxx/yyyyyyy files ,xxxxx/yyyyyyy blocks.(the x and y's are some numbers) After that ubuntu 16.04 is started. Again when I shut down my laptop lubuntu icon shows up. Now, How should I fix the problem?
you didn't install lubuntu - you installed the
lubuntu-desktop or really added the LXDE desktop to your ubuntu system. at the username|passwd screen you'll find a gear type log that will let you select ubuntu (unity DEsktop) or lubuntu (LXDE desktop) as you'd installed both. what you've been left with is only the plymouth screen, which is only a 'icon-screen-filler' as most people don't like seeing text messages as system boots. have a look at
if you want to remove the lubuntu plymouth screen (return it to what it used to be, or select another etc). the plymouth screen is really just a 'theme' type graphic; which was left behind when you removed it (you probably got a warning message telling you this)
/dev/sda6 : clean, xxxxxx/yyyyyyy files ,xxxxx/yyyyyyy blocks. is not an error. Every time you boot Ubuntu it makes a fast check of your filesystem(s), and print this message for each filesystem.
If Ubuntu starts up and works Okay,every thing is fine. You can choose between the installed DEs by clicking on the icon in the upper left corner of the greeter.
