[11:54] Hey, is it possible to be able to follow notifications I receive on Xubuntu [13:30] Hello Alll [13:30] I just installed xubuntu on my old macbook pro which is from 2009 or 2010. [13:31] I fixed the wifi issue there and rebooted the os is stuck right at booting any idea what could have caused this? [13:32] I installed xubuntu 20.04(LTS) on the macbook/ === twinsenbrim is now known as twinsenaxe === twinsenaxe is now known as twinsen === twinsen is now known as twinsenbrim [21:45] hello [21:45] switching from ubuntu to xubuntu now [21:45] to fix some issues with the system [21:46] and... some persisted [21:46] ccz: Like...? [21:46] all the system get stuck when i download something big (like a 20GB game) [21:47] i have a fast broadband and a ssd [21:47] what does it mean that the system gets stuck? It is crashing, or getting very slow? [21:48] like almost all the operations freezes, if there is a video playing and a music running in spotify, both stop, the clock stops... [21:48] the only thing that works is the cursor [21:48] but the download keeps running in the background [21:49] how do you know the download is running? [21:49] what program do you use for downloading? [21:49] how much free space do you have on your hdd? [21:49] it could be a download on firefox or a game on steam [21:49] btw, this is not a xubuntu thing, you might get as well helped in any linux or ubuntu channel, I think^^ [21:49] how do you know the download is still running? [21:49] yes, good idea, hehe [21:49] do you see the hard drive working? [21:50] in 1 minute more or less, the system works again [21:50] and the download gets completed or sometimes corrupted [21:50] i don't know if its a bottleneck between the internet, ssd, memory and configurations in the system [21:50] sounds to me as if your system is swapping and that freezes everything? [21:50] how much free space do you have? [21:51] and how is the usage of RAM? If you let a terminal with the program htop running inside, on the top you can see how much RAM is being used [21:51] lemme see... [21:51] 70GB [21:51] of free space in the ssd [21:52] this time when I downloaded CS: started downloading, the ssd was writing in 60MB/s and the internet following it. [21:52] after like 30s the pc stuck [21:53] the graph suddenly gets to 0MB/s [21:53] some seconds and it grows again, it's like a cycle [21:53] 70GB of 120GB on the SSD* [21:54] where do you see the graph of the network usage? [21:54] in case of steam, in the downloads panel [21:54] can you at the same point look at how much the hdd is writing? [21:54] yes [21:55] that would be interesting [21:55] do you want a screenshot? [21:55] in imgur [21:55] I mean, it is more interesting in terms of time [21:55] hmm [21:55] my suspicion is that you download stuff which is not written to the HDD, and then at some point it is all flushed [21:56] to confirm that, maybe try something like (entering into a terminal): while true; do echo "sync!"; sync; sleep 1; done [21:56] hmm [21:56] this will perform a flushing of all pending filesystem operations every second [21:56] well, until it is done [21:57] so let that run in a terminal while the download is running and check what is happening. [21:57] i'll try... abou the CPU, I saw that it gets 100%, gets stuck, then drops to 60% and goes up gain [21:58] i'll try with other game here [21:58] thanks [22:01] ok I did it [22:01] I downloaded 700MB [22:01] with this sync! printing in the terminal... [22:02] in the middle of the download the "sync!" stop printing for a time [22:02] i thing 30s [22:02] think* [22:02] yes, that is right [22:02] then the download finished [22:02] and the sync is still printing lmao [22:02] it will perform that command until everything which was supposed o be written in that moment has been written [22:02] press Ctrl+C in the terminal to close it [22:02] right [22:03] so did your computer freeze now? [22:03] this time no... [22:03] nothing critical [22:03] I got to go to bed now, but I guess with this you can go on searching for help. [22:03] (in the CS time, after I get back to the computer, "Ubuntu 20.4 ... is not responding" [22:04] The issue is that for some reason your computer buffers all the downloaded data [22:04] very thank you [22:04] and then your ram is full and only then it starts writing to the disk [22:04] it does make sense... [22:04] I had this behavior with my systems as well with external drives, but never cared too much to actually fix it [22:04] it does not really make sense, but that's how I suppose it is^^ [22:05] the OS should start writing as soon as it can [22:05] anyway, I gtg [22:05] gn8 [22:05] thanks [22:05] if you find a solution, I'd also be curious [22:05] really helped [22:05] probably changing the scheduler might do the trick? [22:05] then i got back here [22:05] in #xubuntu [22:05] if i get the solution [22:05] thanks! [22:05] and gn8 [22:05] good night
