[01:37] <anl333> the software needs to support 2-factor authentication with google authenticator. I needed to switch to gdm3 and xscreensaver to get things working. https://www.tecmint.com/enable-two-factor-authentication-in-ubuntu/
[01:38] <anl333> 2-factor authentication works great with Ubuntu but it does not work with KUbuntu
[02:37] <Elliria> Hey there. Does anyone in here use the Night Color widget?
[05:54] <ross__> hello
[05:54] <ross__> who is onlien
[05:54] <ross__> who is online
[05:54] <arraybolt3[m]> me
[05:54] <ross__> great
[05:55] <arraybolt3[m]> I might not know the answer to your question, but I'll try!
[05:55] <ross__> This channel is a professional channel
[05:55] <ross__> Ok
[05:55] <ross__> I think my kde is very laggy
[05:55] <ross__> the animation is slow
[05:55] <ross__> and laggy
[05:56] <arraybolt3[m]> What's your computer's specs?
[05:56] <ross__> no matter I install it on vms or physical machines
[05:56] <arraybolt3[m]> Laggy might be expected on an ancient Intel Celeron, but if you've got an i5 and 8 GB of RAM, then something's wrong with your config most likely.
[05:56] <arraybolt3[m]> OK, good to know.
[05:57] <ross__> 4Gram
[05:57] <arraybolt3[m]> Do YouTube videos play back smoothly on physical machines?
[05:57] <ross__> mybe the ram is too small
[05:57] <arraybolt3[m]> Nah, 4GB ought to be enough.
[05:58] <ross__> yes, video is play back smoothly
[05:58] <arraybolt3[m]> It might just be that you need to change the animation speed. I'm looking up how to do that.
[05:58] <ross__> ok
[05:58] <ross__> I am a new user for kde
[05:59] <arraybolt3[m]> OK, try opening System Settings.
[06:00] <ross__> and I am a programmer, but I think there are many many designs in kde should be improved
[06:00] <arraybolt3[m]> Bah, I'm having a hard time finding a post to tell me where the slider is, but I've got a KDE laptop next to me.
[06:00] <ross__> ok
[06:01] <ross__> let me seach it
[06:01] <arraybolt3[m]> Alright, so open System Settings, click "Workspace Behavior", ensure that "General Behavior" is selected, then you should see an Animation Speed slider.
[06:01] <ross__> OK
[06:02] <ross__> I got it
[06:02] <arraybolt3[m]> (Quick tip - while 4 GB RAM shouldn't cause problems with KDE AFAIK, it might cause problems with doing intensive tasks on your system, so you might want to consider making a bigger swapfile. I can tell you how to do that if you'd like.)
[06:02] <ross__> Ok, thanks
[06:03] <ross__> you are so friendly
[06:03] <arraybolt3[m]> Yeah, sure. Just open a terminal with Ctrl+Alt+T, run "ls /swapfile", and tell me if you see any output.
[06:03] <arraybolt3[m]> (If your tech support can't be friendly, then what's wrong with the world?!)
[06:04] <ross__> huh,yes
[06:04] <arraybolt3[m]> Nice, Then this command sequence should make you a nice 8 GB swapfile to supplement your RAM. Hold on just a sec...
[06:04] <ross__> Ok
[06:05] <ross__> ls /swapfile: out put just a file
[06:05] <arraybolt3[m]> OK, do this:
[06:05] <arraybolt3[m]> sudo rm /swapfile
[06:05] <arraybolt3[m]> sudo fallocate -l 8589934592 /swapfile
[06:06] <arraybolt3[m]> (That's the end of the commands.)
[06:06] <ross__> ok
[06:06] <arraybolt3[m]> (Yeah, ls /swapfile just says if there's already a swapfile on your system. If there wasn't one, there would be a bit of an ordeal adding it into the system, but since there is one, you can just delete the old one, make a new, big one, and be done!)
[06:06] <ross__> ok, I have finished this operation
[06:07] <arraybolt3[m]> Nice. Oh, did either command give any output?
[06:07] <arraybolt3[m]> They should have both been silent, and you should reboot the computer when you're done.
[06:08] <ross__> ok
[06:08] <ross__> thx
[06:09] <arraybolt3[m]> Hey, if you've not done the commands already, do "sudo swapoff /swapfile" before the other two commands.
[06:10] <arraybolt3[m]> If you've already done them, then just reboot and then come back so we can check to see if the swapfile is in use or if we need to tell the system to use it.
[06:13] <ross__> ok
[06:13] <ross__> everything is ok
[06:14] <ross__> after I reboot
[06:14] <arraybolt3[m]> OK, nice. So now can you pop open a terminal with Ctrl+Alt+T, and run "swapon" and tell me if anything happens?
[06:14] <arraybolt3[m]> (If everything is right, it should output some text. If your system needs set up to use the swapfile, it should be silent.)
[06:15] <ross__> nothing happens
[06:15] <ross__> no output
[06:15] <arraybolt3[m]> OK. We will have to configure your system to use the swapfile. Run "sudo nano /etc/fstab".
[06:16] <ross__> I have opened it
[06:16] <arraybolt3[m]> Alright, move your cursor to the very end of the file, and type this line:
[06:16] <arraybolt3[m]>  /swapfile none swap nofail 0 0
[06:17] <arraybolt3[m]> Then press Ctrl+S to save, and Ctrl+X to exit.
[06:17] <arraybolt3[m]> Once that's done, reboot one more time and then do the "swapon" command again to see if it worked.
[06:18] <ross__> ok
[06:21] <ross__> I have reboot
[06:21] <ross__> and run "swap on"
[06:21] <ross__> nothing happeds
[06:22] <arraybolt3[m]> "swapon" is all one word in the command.
[06:22] <arraybolt3[m]> Your terminal will look like "Me@computername:~$ swapon" when you run the command.
[06:22] <arraybolt3[m]> (Obviously, the bit at the beginning will be different, but you get my point.)
[06:24] <ross__> ok
[06:24] <ross__> yes
[06:24] <ross__> I just run swapon
[06:24] <ross__> not "swap on"
[06:24] <arraybolt3[m]> OK. And you don't see anything like "/swapfile file 8G 0B -2" on your screen when you do that?
[06:25] <ross__> no
[06:25] <arraybolt3[m]> Hmm. Can you run "sudo swapon /swapfile", then run "swapon" again and tell me if that does it?
[06:26] <ross__> swapon: /swapfile: insecure permissions 0644, 0600 suggested.
[06:26] <ross__> swapon: /swapfile: read swap header failed
[06:26] <arraybolt3[m]> Pppppt. My fault, I forgot a command. Two commands.
[06:26] <arraybolt3[m]> OK, do this:
[06:26] <ross__> the above is the output of "sudo swapon /swapfile"
[06:26] <arraybolt3[m]> sudo chmod 0600 /swapfile
[06:27] <arraybolt3[m]> sudo mkswap /swapfile
[06:27] <ross__> Ok
[06:27] <ross__> Setting up swapspace version 1, size = 8 GiB (8589930496 bytes)
[06:27] <ross__> no label, UUID=9301360c-1f46-47c4-9561-0d2549127706
[06:27] <ross__> the output
[06:27] <arraybolt3[m]> Nice.
[06:27] <arraybolt3[m]> OK, try "sudo swapon /swapfile" again, then "swapon" again.
[06:28] <ross__> no output
[06:28] <arraybolt3[m]> Is that after both commands, or just after the first one?
[06:28] <ross__> NAME      TYPE SIZE USED PRIO
[06:28] <ross__> /swapfile file   8G   0B   -2
[06:29] <ross__> output
[06:29] <arraybolt3[m]> Hey, there we go!
[06:29] <ross__> great
[06:29] <arraybolt3[m]> OK, reboot one more time, and that should do it. (Sorry to have slowed you down with forgetting the chmod and mkswap part...)
[06:32] <ross__> I have reboot
[06:32] <arraybolt3[m]> OK. Just do one more "swapon" to verify that the system is still recognizing the swapfile. If so, that's it!
[06:33] <ross__> NAME      TYPE SIZE USED PRIO
[06:33] <ross__> /swapfile file   8G   0B   -2
[06:33] <ross__> Ok
[06:33] <arraybolt3[m]> Alright, your swapfile is working. That should help your system survive better during programming.
[06:33] <arraybolt3[m]> Is your desktop also not so laggy now?
[06:33] <ross__> Ok, thanks
[06:33] <arraybolt3[m]> 👍
[06:34] <ross__> no, slightly better
[06:34] <ross__> Thanks
[06:35] <arraybolt3[m]> OK. You can keep fiddling with the animation speed to see if you can make it as good as possible. Glad to be able to help!
[06:35] <ross__> Ok
[11:58] <BluesKaj> Hi all
 What is swapfile? (re @IrcsomeBot: <arraybolt3[m]> Alright, your swapfile is working. That should help your system survive better during programming.)
 And what it dose?
[19:31] <arraybolt3[m]> Oov: If you're still here, a swapfile is a file on your hard drive that your system can use in place of RAM. If your RAM fills up, it can move stuff to the swapfile, allowing you to do tasks on your system that require more RAM than you actually have.
 Hi, everybody:)
