x360 OLED burn in
I'm new to this wiki, so I didn't want to modify anything without permission from the "maintainers"...
The x360 features an OLED display which is prone to burn in. To prevent severe contrast of burned in pictures, most manufactures implement a burn in protection algorithm - mostly pixel shifting - in order to reduce the contrast of the burned in picture making its appearance less obvious. The x360 unfortunately lacks such an implementation both in Windows and Linux OSes. However I have written a small kernel patch (or maybe it's more of a hack) for the i915 kernel driver causing the picture to be shifted imperceptibly effectively reducing the effects of burn in. Of course I am willing to share and I thought this might be the right place to do so.
- Hi, welcome to the wiki! In general every wiki contributor can contribute to our common content, considerate that you ask. See the quicklinks at the left for our help pages. With respect to your contribution for an
i915patch, let me make a remark: this wiki focuses content on Arch and we strive to keep source code in the articles to a minimum (too long is unreadable and out-dates). Given, to use your patch will require frequent rebuilding/patching on kernel updates, I suggest that you first look into packaging it into the AUR (and look at DKMS, perhaps AUR is related to your patch too). This will make using it for you and any other user much easier. Likewise the description in the wiki gets simpler & more accurate over time. - Hope that makes sense. --Indigo (talk) 18:28, 26 November 2018 (UTC)
