From b32fd10dd6fc1292d78a3a6a6cb87e1ad904f142 Mon Sep 17 00:00:00 2001 From: Pascal Rigaux Date: Mon, 28 Feb 2005 23:06:31 +0000 Subject: - remove ddcxinfos, replaced by monitor-edid (which is in a separate package) - add many resolutions (they are structured by aspect ratio for next move) - put the "Monitor preferred modeline" from EDID in xorg.conf - for this ModeLine must be exported from the monitor section - specifying a VendorName|ModelName in auto_inst is valid, don't overwrite it with edid probe - the strange /dev/zero needed (?) by ddcxinfos is no more needed - field {size} is now {diagonal_size}, and is no more "corrected" - add @CVT_ratios and @CVT_vfreqs (unused at the moment) - Getopt::Long is needed by monitor-parse-edid --- tools/ddcprobe/x86emu/debug.c | 431 ------------------------------------------ 1 file changed, 431 deletions(-) delete mode 100644 tools/ddcprobe/x86emu/debug.c (limited to 'tools/ddcprobe/x86emu/debug.c') diff --git a/tools/ddcprobe/x86emu/debug.c b/tools/ddcprobe/x86emu/debug.c deleted file mode 100644 index ed8f2f0e0..000000000 --- a/tools/ddcprobe/x86emu/debug.c +++ /dev/null @@ -1,431 +0,0 @@ -/**************************************************************************** -* -* Realmode X86 Emulator Library -* -* Copyright (C) 1996-1999 SciTech Software, Inc. -* Copyright (C) David Mosberger-Tang -* Copyright (C) 1999 Egbert Eich -* -* ======================================================================== -* -* Permission to use, copy, modify, distribute, and sell this software and -* its documentation for any purpose is hereby granted without fee, -* provided that the above copyright notice appear in all copies and that -* both that copyright notice and this permission notice appear in -* supporting documentation, and that the name of the authors not be used -* in advertising or publicity pertaining to distribution of the software -* without specific, written prior permission.
