My Ubuntu installation is so laggy and unresponsive. Firefox takes 10 seconds to start. Thunderbird takes 20 seconds or more.

I frequently have to hard restart.

I'm about to stop using Ubuntu if I can't improve performance.

I have an Asus X555 laptop and it has run beautifully for years. It has an i3-5010u CPU with Mesa Intel HD graphics 5500 (Broadwell GT2)

I use X11 windowing and GNOME 3.36.8.

free -h:

              total        used        free      shared  buff/cache   available
Mem:          3.7Gi       1.7Gi       180Mi       380Mi       1.9Gi       1.4Gi
Swap:         2.0Gi       1.0Mi       2.0Gi

df -h | grep -v loop:

  • How much RAM/swap/disk space do you have? [Edit] your Question and show free -h;df -h | grep -v loop. While we are here to help, your threat to "bail out" has no value. If some other OS solves your problem, use it. – waltinator May 18 '22 at 01:25
  • Thanks for responding. I'm sorry - I'm trying to format the table but it's just one big chunk. – Ackerman65 May 18 '22 at 02:20

    If any of the other mounts are NTFS, that can slow things down. Make sure Windows fast start up is off, as updates turn it back on. Some things to review: https://askubuntu.com/questions/1284302/is-it-possible-to-make-ubuntu-20-04-boot-faster – oldfred May 18 '22 at 02:31

    Full drives can also slow down systems. You might want to see about freeing up space on your external Toshiba drive. – Terrance May 18 '22 at 02:42

    4GB of RAM is on the low end. In fact the minimum requirements of Ubuntu Desktop recommend 4GB. This does not leave a lot of resources for RAM heavy applications like a web browser. As time has passed, webpages and applications have demanded more and more RAM, which can result in slower performance with aging or lower spec hardware. You may get better performance installing Xubuntu or Lubuntu as these official flavours of Ubuntu have desktop environments that are less taxing on resources, especially RAM. – Nmath May 18 '22 at 02:49
  • Thank you folks for your replies - I will run through the above suggestions and see. – Ackerman65 May 18 '22 at 23:25
