Why Ubuntu got freezes unexpectedly?
I have installed fresh Ubuntu 20.04.2 LTS as a primary os. After running it, It got freezes several times and even the mouse crusor doesn't respond and sometimes it got reboot and sometimes I have to press power button to shut it down. It doesn't respond until I manually shut it down and start my pc again and Here's my PC specification
- Memory - 2GB
- Processor - Intel® Pentium(R) CPU B960 @ 2.20GHz * 2
- Graphics -Intel® HD Graphics 2000 (SMB GT1)
- Disk capacity - 500GB
I am using ubuntu latest version It even get freeze while I am not using any program. So, is it some pc hardaware issue or what ?
I agree with @ArchismanPanigrahi. I'd check what swap you have enabled; and for sure consider running a lighter desktop.
I QA-test various systems (esp. Lubuntu) on different hardware but rarely use a laptop with 2GB for main Ubuntu as it makes no sense as the minimum required isn't met, ie. https://help.ubuntu.com/community/Installation/SystemRequirements lists requirements as
Ubuntu Desktop Edition
- 2 GHz dual core processor
- 4 GiB RAM (system memory)
- 25 GB (5 GB for minimal) of hard-drive space (or USB stick, memory card or external drive but see LiveCD for an alternative approach)
- VGA capable of 1024x768 screen resolution
- Either a CD/DVD drive or a USB port for the installer media
- Internet access is helpful
so problems should have been expected in your case given you've not got the minimum specs for your installed OS.
Lubuntu is not your only choice; the best choice depends on what apps you'll run (eg. if you want to use GTK3 apps I'd most likely use Xubuntu instead); but Lubuntu is the lightest out-of-box.
Adding "nolapic" boot parameter did the trick but it disables my one cpu core so perfomance seems to be decreased.
