Re: [Dorset] Kubuntu hanging
Consider this sorted. I changed the monitor for another LG Flatron from our old computer, and it is behaving well. I guess the old monitor is giving up.

Re: [Dorset] Kubuntu hanging
If you have an older kernel on your system boot using that to make sure its not a kernel issue Tim H On 11/12/2022 12:55, Peter Merchant wrote: If I leave my Kubuntu 20.04 for awhile, I have usually left Thunderbird and Vivaldi up, and when I come back and try and do something the computer goes off into never-never land, the screen goes blank, and I can hear the HD crunching, and it needs the power button hold down to shut it down.

Before you do anything too drastic, I would suggest a few checks. Here's what I would do: 1. Open System Monitor and check the figures for memory, disc and CPU. High usage of any of these might give a clue to follow up. 2. Do the figures for memory usage stack up with the amount of RAM in the system? 3. If nothing looks wrong initially, leave System Monitor running and see if any of the values are increasing over time. 4. If everything looks OK, boot into memtest and make sure that the hard disc is OK. There may be other suggestions forthcoming. -- Terry Coles -- Next meeting: Online, Jitsi, Tuesday, 2023-01-03 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
