[11:32] jimtendo-X540S, why an encrypted swap? [11:56] BluesKaj: Kubuntu set it up by default when I installed Full Disk Encryption. [11:57] 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] Readable in the swap partition*, sorry. [11:59] perhaps a swap file would use less cpu , and that can be encrypted too. [12:00] BluesKaj: tried that unfortunately :( Still same issue. [12:00] 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] 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] the swap file won't decrypt the data ...correct me if I'm wrong [12:04] 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] well, guess you could always google :-) [12:05] 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] I'll take a look now, thank you for your help! Appreciate it! [12:05] jimtendo-X540S, let us know what you find out [12:06] BluesKaj: I don't think that's the case, unfortunately :( [12:07] http://askubuntu.com/questions/313564/why-encrypt-the-swap-partition [12:09] jimtendo-X540S, oddly enough their expalanation makes no sense to me , how does the data become decrypted in swap ? === ian is now known as Guest88415 [12:11] 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) [12:18] bigithepi [12:19] 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] hy [15:28] bien ou bien === kubuntu is now known as Guest54979 === Guest54979 is now known as kubuntu__ === leftist_ is now known as leftist === bruno is now known as Guest9596 === Zren_ is now known as Zren === kubuntu is now known as Guest73756 === Fritigern_ is now known as Fritigern === efm__ is now known as efm [23:28] hi! [23:29] how are you? [23:29] hi.. i m kubuntu user [23:30] from sweden [23:30] today i traing iinstall lubuntu for the first time! I think it is very powerfull solution for old netbook [23:30] hi gorgen! [23:30] I'm from Italy! [23:30] *training [23:31] i prefer xubuntu for old laptops, like the mac interface look [23:32] but lubuntu works fine to
