From b22a15a5aca34c8f59b770f858b1c21d347175e0 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Fri, 12 Nov 2021 14:32:29 +0100 Subject: Documentation/admin-guide: Document nomodeset kernel parameter The nomodeset kernel command line parameter is not documented. Its name is quite vague and is not intuitive what's the behaviour when it is set. Document in kernel-parameters.txt what actually happens when nomodeset is used. That way, users could know if they want to enable this option.
