[01:37] <weeraft> Hello everyone,how could I change the image of  login background?
[02:01] <guiverc> weeraft, the file `/usr/share/sddm/themes/lubuntu/wall.png` is what is used by sddm as background; you didn't provide release details; but it's likely a softlink to something like ../../../lubuntu/wallpapers/2110-friends-dark.png   (which is 21.10)
[02:06] <weeraft> Thanks!
[03:21] <gnomo> Oi, gente! Alguém de SP? Comecei hoje com o Linux..
[08:34] <aiky> hello. i have an issue with sound. it's working fine for a little while before i just hear i loud siren-like noise, which continues till i stop what i was listening to. any idea what the cause might be? it's an old atom processor laptop
[09:03] <guiverc> aiky, what release of Lubuntu?
[09:08] <aiky> 21.10
[09:09] <aiky> guiverc ^
[09:10] <aiky> it also happened in the newest version of mint xfce. i actually wiped mint and went with lubuntu after that today
[09:15] <guiverc> I'd likely see if it does it using a live system (same 21.10), a different kernel stack (20.04 with GA kernel stack the closest I'd go; I mean a very different stack) & ensure it's not cabling/sound-system (grounding issue etc).  aiky 
[09:16] <guiverc> you could look at what kernel module (driver) is being used (`lshw -C sound` for example to get info) & look online to see if it's a common issue with your chipset..
[09:23] <aiky> guiverc: oh dear, sounds like this might be a little too complicated for me to deal with. because i don't really understand what you said besides using a live system, hehe
[09:25] <guiverc> Ubuntu LTS releases have kernel stack choices; 20.04 & 20.04.1 media uses the GA stack (ie. 5.4 kernel that remains 5.4; ie. stable);  20.04.2 & later media for Lubuntu uses HWE that changes during life-cycle; 5.8 at 20.04.2, 5.11 at 20.04.3, 5.13 at 20.04.4 (which is what is changing right now..)
[09:31] <aiky> ah
[09:31] <aiky> i'm testing in a live session now 
[09:33] <aiky> i know there was some issues with sound with this processor before, sound didn't work,. i think it was fixed with kernel 5.4, iirc 
[09:36] <aiky> it happened again. been playing a youtube video for 3+ minutes then suddenly that sound started, but the youtube video also stopped for some reason 
[09:39] <aiky> wtf. after exiting the live session, i can no longer boot into my lubuntu installation
[09:41] <aiky> something-something invalid signature 
[09:41] <aiky> and "error you need to load the kernel first" 
[09:42] <aiky> i thought wiping windows 10 and going with linux on this laptop would be smooth sailing, but no, far from it *sigh*
[10:18] <lo> what are the minimum needed ram for  lubuntu
[10:18] <lo> Is it okay for me as i have 2gb of ram on my computer
[14:10] <maya_> hello
