(Solved / answered) How to enable i915.alpha_support=1

Post by Massively ignorant » Thu Mar 08, 2018 1:19 pm

Greetings all,

This will be somewhat confusing due to some issues with where some replies were placed. I'm very grateful to the respondent for the information provided, it's that somehow information pertaining to my inquiry in the thread: Key board and mouse lag / response delay, got into my thread about Kernel Swapping. For full details on my particular machine and for the pertinent background to this query please peruse my thread: Key board and mouse lag / response delay.

In the thread about Kernel swapping, my respondent wrote; enable i915.alpha_support=1Key. Well I have no idea what that means or how to do it. My respondent has been providing me information about my Keyboard and mouse lag / response delay issues. I have requested the most recent post from that respondent be moved to my thread about lag / response delay. However as of this writing, the post I'm making reference to was still in my thread about Kernel swaps.

As confusing as all that is, I still have questions about how to enable i915.alpha_support=1Key.

For anyone who has had the fortitude to have waded through that swamp, and would be willing to explain the matter or point to an explanation, I would be most appreciative.


Thank you and respectfully, Massively ignorant

It probably means to add to the kernel GRUB_Cmdline: i915.alpha_support=1.
