You can try disabling it by adding `i915.enable_rc6=0` boot flag. To do this from a running system and make it permanent, run the following terminal command: 1. {icon terminal}`EDITOR=gedit sudo /etc/default/grub` File ///etc/default/grub// will be opened in `gedit` with administrator privileges (so be careful with the next step). 2. Find the //**GRUB_CMDLINE_LINUX**// line 3. Change it to look like this: ``` GRUB_CMDLINE_LINUX="i915.enable_rc6=0" ``` 4. Save the file. Restart for this to take effect. NOTE: Instead of `gedit` you can use a text editor of your choice.
