From 1acf566195e135bc0b557ecb8ad5395b47d9ad27 Mon Sep 17 00:00:00 2001 From: Max Staudt Date: Wed, 18 Jan 2017 19:10:12 +0100 Subject: [PATCH] drm/bochs: Implement nomodeset Up until now, the bochsdrm driver didn't handle the nomodeset option at boot, and didn't provide a "modeset" module option either. This patch implements both. The new parameter can be used by specifying bochs-drm.modeset=0 at boot time.
