From dcfe2666ffd6316b764801db82092bc62db56e6f Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Mon, 12 Feb 2007 00:55:21 -0800 Subject: [PATCH] [PATCH] fb_videomode_to_var: reset virtual screen parameters fb_videomode_to_var(): reset the virtual screen parameters when converting from an fb_videomode to an fb_var_screeninfo. Without this the old virtual screen parameters are kept. Hence you cannot switch to a video mode with a lower resolution on frame buffer devices that don't support virtual screens and panning, as values are not supposed to be rounded down when they don't fit. I also reordered the assignments to match the order of the individual members.
