This was broken due to bogus manipulations + of a register between the 2 entities. This fix is a big "violent" in + that it always enables the analog output regardless of what is + plugged. It should work though (at the expense of some additional + power consumption). A proper fix should be easy to do once Alex gets + his output mapping rework in. + 2006-04-21 Dave Airlie <airlied@linux.ie> * src/radeon_driver.c: (RADEONRestoreMode): diff --git a/src/radeon_driver.c b/src/radeon_driver.c index a4951775..7180a879 100644 --- a/src/radeon_driver.c +++ b/src/radeon_driver.c @@ -1,5 +1,5 @@ /* $XFree86: xc/programs/Xserver/hw/xfree86/drivers/ati/radeon_driver.c,v 1.117 2004/02/19 22:38:12 tsi Exp $ */ -/* $XdotOrg: driver/xf86-video-ati/src/radeon_driver.c,v 1.92.2.15 2006/04/21 00:44:58 airlied Exp $ */ +/* $XdotOrg: driver/xf86-video-ati/src/radeon_driver.c,v 1.92.2.16 2006/04/21 00:46:53 airlied Exp $ */ /* * Copyright 2000 ATI Technologies Inc., Markham, Ontario, and * VA Linux Systems Inc., Fremont, California. @@ -7776,13 +7776,21 @@ static Bool RADEONInitCrtcRegisters(ScrnInfoPtr pScrn, RADEONSavePtr save, ?
