I updated Ubuntu 14 days ago and have been using it trouble free for that time - in the last 24 hours though my screen would freeze and crash every time I was working with VS Code.

I've seen other recommended solutions like allocating additional swap space using file in my root directory: or launching VSCode with extensions disabled (code --disable-extensions) The first wouldn't work as i have more than 70GB and and running VS Code wouldn't eat all the cores memory. tried to disable extensions and it didn't fix the problem.

Update: I have since uninstalled the app hoping it would fix the problem - if running VS Code is actually the problem and the freezing hasn't stopped. Do I uninstall Ubuntu if I can't restore software to 16.04?

Reset to default

Found a solution that seems to have worked for me so far

I'd a similar problem. Try the following

make a copy of the grub config

sudo cp /etc/default/grub /etc/default/grub.backup

open the file grub file

sudo nano /etc/default/grub

search for a line beginning with GRUB_CMDLINE_LINUX_DEFAULT and add the following parameter to this line

intel_idle.max_cstate=1

update grub

sudo update-grub

reboot

If it doesn't work delete the property and update grub again

    can you add explanation about why this is solving it? (for future readers)

C-state 1 as max avoids the CPU entering on idle state as a consequence of a bad kernel space bug or condition probably produced by a graphic driver.
