Screen flickering on devices with Intel graphics
---
A possible cause can be buggy Intel graphics power management. 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 -e /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.
