Bug 8229

ok, it's been several years since I could use the "ati" driver from x.org AND
watch movies. I use ati for 3d accel, and I like to watch movies. So I would
switch to vesa or do mplayer -fs -vo x11 -zoom file; But I joined #xorg-devel
and they told me to do 

"sudo apt-get install xvattr; xvattr -a XV_SWITCHCRT -v 1;" and this fixed the
problem. And benh said it was a problem with the driver. And I asked if I should
file a bug, and airlied said yes so here it is. The log is below with them
talking with me, maybe that is better to understand then what I wrote so far.


21:33 < Jones_> benh: here?
21:35 < benh> Jones_: yes
21:37 < Jones_> benh: I have this R200 QM Radeon 9100 card, and I can't play
movies(libxv1?). It's been like this for a few
                years. From Fedora Core(a few years ago), through debian and now
on Ubuntu edgy.
21:37 < Jones_> I'm using the x.org "ati" driver on it.
21:38 < Jones_> I'm sshed into this box, and I did gdb /opt/xorg-debug/Xorg pid;
but I'm not sure how to get information
                from gdb, about the driver or such.
21:38 < airlied> Jones_: what does it do? crash when you play the movie or just
display garbage?
21:38 < benh> 9100 isn't r200 is it ?
21:38 < benh> it's rv250 no ?
21:38 < benh> or 280 even
21:39 < benh> not sure which
21:39 < Jones_> youtube/flash work fine with videos, and if I switch to "vesa"
that works also. Or I can do in mplayer,
                "mplayer -fs -vo x11 -zoom file" but with if I just click on a
movie with the "ati" driver, I get a black
                screen with audio working fine.(been like this for years)
21:39 < Jones_> benh: Radeon 9100
21:39 < benh> looks like an Xv issue ... hrm...
21:39 < benh> yeah, maybe wrong crtc
21:40 < Jones_> benh: not sure, I'm physically looking at the card and it says
"Radeon 9100 128M DDR V/D/VO" on the sticker.
21:40 < airlied> there is an XV_SWITCHCRT attrib..
21:40 < Jones_> But lspci shows me "01:00.0 VGA compatible controller: ATI
Technologies Inc Radeon R200 QM [Radeon 9100]"
21:40 < Jones_> no, I just have one lcd monitor.
21:40 < benh> yeah, it's probably unrelated to the card model, let me find this
xattr thing
21:41 < Jones_> The video card has dvi an s-video. And the blue one(vga?), I
always use the blue one.
21:41 < Jones_> I don't know that much about hardware.
21:41 < benh> it's possible that it's outputing video to the DVI instead or
something like that
21:41 < benh> let me check
21:41 < airlied> try installing xvattr
21:41 < Jones_> k
21:41 < airlied> apt-get install xvattr
21:41 < airlied> hopefully it exists in debian or ubuntu..
21:42 < Jones_> yes it's installing
21:42 < benh> xvattr -a XV_SWITCHCRT -v 0
21:42 < benh> or
21:42 < benh> xvattr -a XV_SWITCHCRT -v 1
21:42 < airlied> 9100 is an R200 alright..
21:44 < Jones_> http://www.rafb.net/paste/results/mbZVOY12.html
21:44 < airlied> try one, then play movie, if it doesn't work try the other..
21:45 < Jones_> k
21:46 < Jones_> When I switch to 1 it works
21:46 < Jones_> aww, this is awesome
21:46 < Jones_> So libxv1 tried to output to 0? But it should have outputted to 1?
21:47 < Jones_> Do I file a bug on the package libxv1?
21:47 < airlied> Jones_: not really sure what the best way to fix it, the driver
should be better at guessing..
21:49 < benh> it's not libxv fault
21:49 < Jones_> Well as far as I'm concerned it's fixed.
21:49 < benh> airlied: well, the driver might not know he's using the analog
output...
21:49 < Jones_> If I need to run a script on startup that's fine. But if I can
file a bug so it's fixed for others with this
                card I want to do that.
21:50 < benh> or rather on which crt he's connected
21:50 < benh> he might have a picture at all by luck :)
21:50 < benh> bad output routing
21:50 < benh> Jones_: it might work for others depending on where the monitor is
plugged too or other bits like that
21:50 < Jones_> So it could be a defective card?(I got it from newegg about 4
years ago)
21:50 < benh> Jones_: or other OEM cards with the same chip wired differently
21:50 < benh> no
21:50 < benh> it's the driver being a bit dumb
21:50 < Jones_> And I've been too cheap to replace it.(but thankfully I didn't
replace it since it works awesome with
                aiglx/compiz hehe)
21:52 < airlied> benh: true.....
21:52 < Jones_> Well I got the ati driver from x.org, and I checked the
changelog, and I saw benh _*_AT_*_
                kernel.crashing.org had the most significant changes to the ati
driver, so I whoised benh on freenode and
                came here and asked. heh
21:55 < benh> hehe
21:55 < benh> I didn't play with Xv bits tho :)_
22:00 < Jones_> So do I do this command everytime I restart? or is it saved in a
config file somewhere now?
22:02 < airlied> Jones_: on restart..
22:03 < Jones_> airlied: Do you know the config file to change so this is
permanent? Or just dump a 2 line script in
                /etc/init.d/xv_fix.sh; then add link in /etc/rc2.d?
22:04 < airlied> Jones_: you have to do it after X starts..
22:04 < Jones_> ahh ok, So I'll have gnome do it I guess.
22:05 < airlied> Jones_: I'm not sure if there is an xorg.conf option....
22:07 -!- HuntsMan_ [n=hunts@pc-72-70-83-200.cm.vtr.net] has joined #xorg-devel
22:07 < Jones_> k, well thanks a lot for the help airlied / benh; I really
appreciate the help.
22:07 -!- HuntsMan [n=hunts@pc-72-70-83-200.cm.vtr.net] has quit [Read error:
104 (Connection reset by peer)]
22:07 < Jones_> Should I file a bug with bugzilla.freedesktop.org ?
22:08 < airlied> Jones_: I think we know about it already but no harm filing it..
22:08 < Jones_> k
22:08 < airlied> it's just difficult to fix..
22:11 < Jones_> I don't see "Driver/ati" listed in bugzilla. Should I do
"Driver/Radeon"?
22:11 < airlied> Jones_: yes...
22:14 < Jones_> k
