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.
Signed-off-by: Javier Martinez Canillas javierm@redhat.com ---
Changes in v4: - Don't mention the simpledrm driver and instead explain in high level terms what the nomodeset option is about.
