[00:30] <vault711> should i get kubuntu?
[11:02] <BluesKaj> Hiyas all
[11:29] <jimtendo-X540S> Hi guys, has anyone else encountered a problem that, when using an encrypted swap, kswapd consumes a very high amount of CPU usage (in my case, 35%+)?
[11:32] <BluesKaj> jimtendo-X540S, why an encrypted swap?
[11:56] <jimtendo-X540S> BluesKaj: Kubuntu set it up by default when I installed Full Disk Encryption.
[11:57] <jimtendo-X540S> BluesKah: As I understand, it's actually a good idea. Saves potentially sensitive information (passwords and keys) from being in the Swap partition in case the PC is ever lost.
[11:57] <jimtendo-X540S> Readable in the swap partition*, sorry.
[11:59] <BluesKaj> perhaps a swap file would use less cpu , and that can be encrypted too.
[12:00] <jimtendo-X540S> BluesKaj: tried that unfortunately :( Still same issue.
[12:00] <jimtendo-X540S> This computer becomes unusable as soon as the swap becomes active. It's only 4gb RAM with a 4gb Swap. Swappiness is only set to kick in when upto 90% ram is used, from memory.
[12:02] <BluesKaj> jimtendo-X540S, my thinking is if the whole disk is encypted then tha data i in the swap file must be in encrypted form as well so if you use a n unencrypted swap then the data there is still encrypted
[12:03] <BluesKaj> the swap file won't decrypt the data ...correct me if I'm wrong
[12:04] <jimtendo-X540S> BluesKaj: Umm... that's an interesting thought. Not sure if it's correct or not, but it might be? Can anyone else confirm this?
[12:04] <BluesKaj> well, guess you could always google :-)
[12:05] <jimtendo-X540S> Either way, to get around this issue, I might just use a swap unencrypted for now... I don't necessarily have anything that is that sensitive, just prefer to follow best practises if I can.
[12:05] <jimtendo-X540S> I'll take a look now, thank you for your help! Appreciate it!
[12:05] <BluesKaj> jimtendo-X540S, let us know what you find out
[12:06] <jimtendo-X540S> BluesKaj: I don't think that's the case, unfortunately :(

[12:09] <BluesKaj> jimtendo-X540S, oddly enough their expalanation makes no sense to me , how does the data become decrypted in swap ?
[12:11] <jimtendo-X540S> I think going in it encryptes and going out it decrypts... so I can imagine there should be a bit of a performance hit there.. but I feel confident that the performance hit I'm getting is unusual... it's insanely slow (I usually just reboot as soon as my swap is activated - it's quicker than waiting for anything to respond)

[12:19] <BluesKaj> jimtendo-X540S, the encryptioon key could be stored in swap, which to me is like winning the lottery...what are the odds , but that's the reason...not a very likely scenario, but that's what the experts over at ##linux just expalined to me
[15:26] <pierre_> hy
[15:28] <pierre_> bien ou bien
[23:28] <user|24769> hi!
[23:29] <user|24769> how are you?
[23:29] <gorgen> hi.. i m  kubuntu user

[23:30] <user|24769> today i traing iinstall lubuntu for the first time! I think it is very powerfull solution for old netbook
[23:30] <user|24769> hi gorgen!
[23:30] <user|24769> I'm from Italy!
[23:30] <user|24769> *training
[23:31] <gorgen> i prefer xubuntu for old laptops,  like the mac interface look
[23:32] <gorgen> but lubuntu works fine to
