Thanks Mark,

If you're out of ideas, there's no hope of me fixing it.

Reinstall it is then, as soon as I find the time.

Thanks for your help.

Mark,

I've just discovered from the 'properties' of the partition on which Ubuntu is installed, that some contents are unreadable.

Does that throw any light on the problem? I suspect it's confirmation that a reinstall is needed.

That may just mean the user under which you opened the properties doesn't have permission to read all the contents.

Have you either

a) opened that utility as root

or

b) run a file system check .. IIRC we already did this (?)

I don't know how to do that..

Not sure, but I don't think so - still a linux newbie...

Incidentally, we have a laptop also running Ubuntu 16.04 which is also running very slowly, and which also shows unreadable contents on the Ubuntu partition. I assume that probably confirms that this is a permissions problem...

I'm having one last shot at this before I go for the nuclear option...

Given the amount of disk accessing I'm hearing (not all the time, but quite often) I'm wondering whether the partition on which Ubuntu is installed is nearly full.

Problem is, I don't yet know how to find out. I'm googling (with duckduckgo) but any clues appreciated (ubuntu is on sdc5).

You can easily obtain that information:
Code: [Select]
df -h /dev/sdc5

Thanks SeZo,

41% full. Doesn't even slightly explain all the disk accessing, especially as I understand that fragmentation isn't a problem in Linux.

I suppose I'm down to the nuclear option...

I'm still gnawing away at this, and beginning to think it's got something to do with the way the disk containing Ubuntu and Windows is partitioned.

Does the following look right?

Thanks for any opinions..

Mike, please stop adding images as attachments unless expressly asked to do so by site admin .. If you need to add an image, please upload it to somewhere such as:-
https://imgur.com
then enclose the URL of your image in IMG tags.

Please see here for how:
https://linuxforums.org.uk/index.php?topic=12404.msg101976#msg101976



The images I just removed looked perfectly OK to me, but then I can't see what that command/coutput has to do with "partitioning" ?
(that just told you how space was being utilised on those partitions)

Sorry to revisit this thread after so long.

Just thought it might be helpful to tell you that it looks like the motherboard is the problem.. Sound, wi-fi and ethernet are now causing random problems.

Just about to start a new thread, asking for motherboard recommendations..

I'll mark this solved. Thanks for your help, folks.
