So, there are many problems in Ubuntu 17.10. Many problems regarding Screen Lagging and Mouse Lagging. Personally i tried most of the things out there, but one thing, this is temporary issue, hope to get the update soon.
Hope, this post will help you, Good Luck.
Now, First of all, Open a Terminal and write these command one by one.
sudo nano /etc/default/grub
and now add this line ” acpi_rev_override=1 ” (without quote) to GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash”, just like the below image.
Second Step- ( run these commands one by one )
sudo fallocate -l 1G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
And the last method –
Ubuntu 17.10 uses wayland by default. however, you can switch back to Xorg, without to install anything, all you need to do is:
- Log out from you current user.
- Under the password, near the “unlock” button, you will have something like a settings-icon.
- Click it, and choose the second option(the one says “xorg”)
- And there you have it! the good old xorg session, with no more cursor lags!
