Discord making Ubuntu stutter and internet drops (like in an interval)

Ask Ubuntu Asked by Tuvel on January 3, 2022

I’ve installed Ubuntu 20.04 on a new SSD I’ve just bought (Samsung EVO 860 500GB).
I love it a lot, BUT!!!
I have a really frustrating issue! whenever I use Discord, Ubuntu starting to stutter. Like windows are moving at 24fps and like every 3 seconds the whole system freeze for a 0.5-1.0sec.

I’ve tried to fix the problem using Discord Canary (alpha software) and it did fix the problem only when I’m not in a voice chat! but when I am, the problem persists.
Today I’ve tried to play Minecraft with my friends and I was using Discord to communicate with them.
As I said above, the problem occurred exactly as I mentioned. But this time with a worse problem, every time there is that "freeze" I would "disconnect" from my network, but not exactly… I’m still connected to the WiFi but the server in the game itself freezes and I can’t hear my friends. (Again, for about 0.5-1.0sec…)

I’m dual booting with Windows 10. when that problem happened I’ve decided to boot into Windows to test if the problem is with my internet (just to check if the problem with my internet is actually my internet) but I’ve found out that there is no problem on Windows 10 whatsoever. The Internet is working perfectly fine (500Megabits Down & 100Megabits Up).

PLEASE! This is the only issue I’ve with Ubuntu that made this experience really frustrating!

grep -i discord /var/log/syslog*

Log was too big (probably because this is a lot of errors or something like that).
So the log is HERE

From the comments...

Discord and Discord Canary

Discord Canary is alpha level software, which is bad enough, but as you note, it's bombing syslog. Alpha level software should only be run by developers who know how to deal with all of the expected errors. I'd remove Discord Canary and run the normal full release of Discord (if you have to run it at all).

In my opinion, Discord has a number of problems, and I consider it spyware. When you run it, it has code to determine what other applications that you're running... and who's business it that? Certainly not Discord or their developers. Also, if you're running the snap version, it requests permissions to do activity outside of its protective sandbox, which should never happen... and then it REALLY bombs /var/log/syslog and /var/log/auth.log.

I'd first immediately remove Discord Canary, then I'd install the normal "stable" Discord release... not the snap version, but a normal .deb release. See

If the "stable" release still has a stuttering problem, try changing vm.swappiness back to 60 and see if that helps... sudo sysctl vm.swappiness=60 (for a temporary change only). If that improves things, to make it permanent...

Set vm.swappiness=60 (based on 16G RAM and 2G SWAP), this way...

sudo -H gedit /etc/sysctl.conf # edit this file

Search for an existing vm.swappiness= entry...

CTRL+f vm.swappiness

  • If found, edit it to say vm.swappiness=60

  • If not found, add vm.swappiness=60 at the end of the file

Save your edits and quit gedit

sudo sysctl -p

Update #1:

To update your /swapfile from 2G to 4G...

Note: Incorrect use of the dd command can cause data loss. Suggest copy/paste.

sudo swapoff -a           # turn off swap
sudo rm -i /swapfile      # remove old /swapfile

sudo dd if=/dev/zero of=/swapfile bs=1M count=4096

sudo chmod 600 /swapfile  # set proper file protections
sudo mkswap /swapfile     # init /swapfile
sudo swapon /swapfile     # turn on swap
free -h                   # confirm 16G RAM and 4G swap
reboot                    # reboot and verify operation

Add this line to /etc/fstab...

/swapfile    none    swap    sw      0   0

Update #2:

Updated the Nvidia driver to, and that seems to have fixed it.
