[05:44] <Guest72> Lubuntu is pretty laggy for me
[05:44] <Guest72> I expected LXQt to be more lightweight
[05:44] <Guest72> What are the most lightweight/fast Desktop Environments around?
[05:53] <guiverc> Guest72, LXQt is likely the fastest; Qt5 is far lighter than GTk3, but the DE is not the only issue relating to lag; if using a Qt5 DE but not using Qt5 apps then you're likely wasting resources which can slow down a limited-resource machine
[05:55] <Guest72> Im using a 2008 Laptop Libreboot X200s
[05:55] <Guest72> so its good but starting to show its age
[05:56] <Guest72> that being said, if this laptop could handle linux in 2008, it should be able to handle linux today
[05:56] <Guest72> Im using Lubuntu 20.04 LTS currently
[05:56] <Guest72> But it gets somewhat laggy
[05:56] <Guest72> sometimes
[05:57] <guiverc> I'm keying this into 2009 dell desktop... works great here... Do you have swap enabled?   That is the biggest issue I've had on some devices
[05:57] <Guest72> How do i check?
[05:57] <guiverc> https://discourse.lubuntu.me/t/how-to-create-a-swapfile-in-lubuntu-20-04-20-10/1959
[05:57] <guiverc> at the start of the post is a 'check' (free -h)
[05:58] <Guest72> Does the SWAP handled by the OS automatically?
[05:59] <guiverc> If you created a swap partition chances are it was automatically used; however the Lubuntu 20.04 LTS did not create one by default (it allowed you to create one but it relied on you opting to do so)
[05:59] <Guest72> Where was the option?
[05:59] <guiverc> Maybe more detail - https://discourse.lubuntu.me/t/swap-and-lubuntu-21-04-hirsute-and-up/2591
[05:59] <Guest72> I dont think I manually enabled the SWAP
[05:59] <Guest72> Should I add it now?
[06:00] <guiverc> I don't know how much RAM you have, but I for sure use swap on my thinkpad x201 with 4GB of ram; refer the first link I provided (for creating a swap file... I may have used swap partition; I forget)
[06:00] <Guest72> Yeah I only have 4 gigs of ram I think
[06:00] <Guest72> maybe 8
[06:02] <Guest72> free
[06:02] <Guest72>               total        used        free      shared  buff/cache   available
[06:02] <Guest72> Mem:        3664908     1273856      829172       69112     1561880     2093392
[06:02] <Guest72> Swap:             0           0           0
[06:02] <guiverc> I'd create a swap file following the first link I provided :)
[06:03] <Guest72> free -h
[06:03] <Guest72>               total        used        free      shared  buff/cache   available
[06:03] <Guest72> Mem:          3.5Gi       1.2Gi       814Mi        61Mi       1.5Gi       2.0Gi
[06:03] <Guest72> Swap:            0B          0B          0B
[06:03] <Guest72> Loks like I got 3.5gigs of ram :o
[06:03] <Guest72> 2 gigs of ram?? 1.2 g used, 800mb free = 2 gigs ram total??
[06:03] <guiverc> nah you have 4GB, but your system uses part of the 4GB for it's own detail
[06:03] <Guest72> ok
[06:03] <guiverc> s/detail/purposes; 
[06:03] <Guest72> only 814 mb free
[06:04] <Guest72> What does making a SWAP do?
[06:04] <do5rsw> yeah but 1.5Gb in buffers/cache
[06:04] <do5rsw> if more ram is required linux will reduce the buffers/cache
[06:05] <Guest72> so what can the SWAP do?
[06:06] <guiverc> the second link I provided has a link to Swap FAQ at the top.. look at it if you want more details  (2nd post was 21.04 & up but included more detail thn first)
[06:06] <Guest72> sudo dd if=/dev/zero of=/swapfile bs=1M count=8192 ?
[06:06]  * guiverc is away feed birds awhile
[06:07] <Guest72> I didnt even see the GUI create swap ability
[06:10] <do5rsw> Guest72, hm you free -h states there is up to 2Gb of ram aavailable if needed.
[06:11] <do5rsw> if you plan to do something that would use that up - swap might be helpful
[06:11] <Guest72> How should I secure my Linux OS more?
[06:11] <Guest72> I have a UFW firewall
