After upgrading to Ubuntu 20.10 the system is slow

Asked by Alexandru Vasiu on 2020-10-19


I upgraded my laptop (Thinkpad T590 with Nvidia MX250) to Ubuntu 20.10 from Ubuntu 20.04 and now I'm experiencing a lot of issues:

1. The overall performance is bad (the system is slow), even when I try to write a command in the terminal, it has a lag. Each app has a lag.
2. The network connection is a bit slower than before.
3. When I try to see a video (or even when using Google Meet), the video is interrupting a lot even if I have 30-40 Mb/s download speed (before this was at 100 Mb/s sometimes).

Is this because of kernel 5.8? What should I do? Can I rollback to Ubuntu 20.04?

Thank you

I suggest you report a bug. Groovy is not ready and not stable.

The only way to roll back is with a clean install and wiping Groovy off. Note that Focal is LTS and supported until April 2025. Groovy is only supported for 9 months....

I'm facing the same issue, broadly speaking. I am quite certain it is Graphics resources/drivers related, but that's where my diagnosis skills lack. Was a bug raised for this by the OP? How could I diagnose this further?

Pratik, please make your own question rather hijacking someone else's

Andrew, my intentions were quite the opposite actually. I wasn't hijacking the question, instead asking for an update on what you had asked for in your first question. So that I could follow up the progress of that bug report. I will also refrain from adding my own question for now, since I have absolutely no more value to add than what this question does.

Hi Pratik,

No update yet. I will try to update the kernel next days to see if it helps.
