First of all I'm not an Expert in Ubuntu.

I am using Ubuntu 14.04.4 on my Dell Inspiron 11 3147. Since Ubuntu 14.04.4 Released, it's freezing frequently. Especially when I'm Browsing the Internet (I'm currently using Opera but I tried Chrome and Firefox too). It was okay when I was using 14.04.3. But the Latest Version is totally Freezing my Laptop (Even Mouse doesn't work). I tried Magic SysRq Key Combination (Alt + SysRq + REISUB) but nothing happens. What can I do to fix this Problem?

Thank You!

P.S. I fresh installed 14.04.4 when it Released. And the Same thing happens on Ubuntu 15.10 too.

  • Please edit your question and add output of lspci -k | grep -EA2 'VGA|3D' terminal command. – Pilot6 Feb 25 '16 at 12:29

  • I've never got an acceptance for my answer while 2 other people thought my answer was valuable... Any problems with my answer??? :-( – Fabby Mar 27 '16 at 22:51

An Atom processor? Running Ubuntu??? :O

I'd start looking at Lubuntu and install that!

Probably your system was just barely fitting until 14.04.4 when it started swapping like mad and that just looks like it's freezing: it's actually still working, but 1000 times slower then before...

Sorry to be the harbinger of bad news...

Alternatively, just get rid of that thing and buy a new computer instead of using Lubuntu (which I've ran on Atom processors a long time ago, though not recently)

    Other laptops are bulky to Carry, that's why I use this laptop. And Windows 10 runs just fine on this laptop. Ubuntu also runs good just the Freezing problem. But now, it's freezing much less than before. Another thing, My Laptop has actually a Pentium Processor but it's showing Atom, I don't know why. BTW, thank you for your comment. – Abdullah Sabbir Mar 16 '16 at 10:49
  • If you could: leave the machine for about 15 minutes next time it "freezes" and then try to run the command free --human and post the output into your question, I can prove this to you! (or try Lubuntu from a DVD/USB stick and see if it happens there too) Oh and if this answer did help, just click the little grey ☑ at the left of this text right now turning it into beautiful green, which means Yes, this answer is valid! ;-) – Fabby Mar 16 '16 at 14:49
  • Installed Xubuntu. Same thing is Happening. – Abdullah Sabbir Mar 29 '16 at 17:04
  • I didn't say Xubuntu: I said Lubuntu... – Fabby Mar 30 '16 at 8:00
  • I don't like the interface of LXDE. That's why I installed Xubuntu. Maybe I'll just wait for 16.04. – Abdullah Sabbir Mar 30 '16 at 10:56
