Back
Both CRT and SVIDEO are connected on a ATI Radeon 8500 using the Shrike
XFree86 4.3.0 radeon driver. X will not come up unless I unplug SVIDEO
and reboot the box.
log and config:

http://jimcable.home.mindspring.com/rh9/XFree86.0.log
doc:

XFree86 4.2 had Option "CrtScreen " that worked around this behavior and
I could always leave the SVIDEO connected. This option is not found in
4.3.
Now I don 't really mind that SVIDEO doesn 't work with the radeon driver
(see my workaround below), but I do mind having to reboot every time
that I forget to unplug the bloody SVIDEO cable and want to use the
radeon driver.
So after spending two days juggling Options in XF86Config, I have placed
my hopes on a patch that will free me from evil reboots.
QUESTION: Is it possible to patch around this behavior (or even get CRT
+ SVIDEO out working) in
xc/programs/Xserver/hw/xfree86/drivers/ati/radeon_driver.c?
Thanks,
Jim
WORKAROUND
ATI Radeon 8500 CRT + SVIDEO does work using fbdev at 800x600
1) grub.conf > append "vga=788 " to the kernel line
2) XF86Config >Device >Driver = "fbdev "
3) XF86Config >Screen >Display >Depth 16
4) XF86Config >Screen >Display >Modes "800x600 "
This configuration works great for playing video/dvd from xine. BTW
vga=788 is the only mode that seems to work. vga=789 causes the colors
to shift blue on both CRT and SVIDEO. Using vga=791 and vga=792 causes
SVIDEO to go blank. 1024x768 SVIDEO works in windows so ATI must be
doing some magic in their driver. I haven 't tried radeonfb yet. Perhaps
it will work at 1024x768.
