fails to start without -nodga option

[Lukas Sabota]

Binary package hint: xawtv

I'm running Edgy on x86. When I start xawtv, I get this output:
This is xawtv-3.95, running on Linux/i686 (2.6.17-10-386)
X Error of failed request: XF86DGANoDirectVideoMode
  Major opcode of failed request: 136 (XFree86-DGA)
  Minor opcode of failed request: 1 (XF86DGAGetVideoLL)
  Serial number of failed request: 65
  Current serial number in output stream: 65

I'm ready and willing to provide more information to fix this bug.

TEST CASE:
 Make sure the system is effected: On a gutsy system with NVidia graphics
 run:
  xdpyinfo -queryExtensions | grep NV-GLX
 which should return something like
  NV-GLX (opcode: 146)
 Try to run xawtv from the command line.

Thank you for your bug report.

Can you still reproduce this? If so, does it go away if you run xawtv with the -nodga option?

xawtv -nodga

[Diego Gaustein (gregorovius)]

I can reproduce this on latest Feisty. It does work with the -nodga option. I believe it's related to the nvidia-glx drivers.

[Philippe Chabbert (p-chabbert)]

Same problem with feisty, AMD64, nvidia 7600GS and Pinnacle pctv card (BT878).
Error message when starting xawtv in a terminal :

This is xawtv-3.95.dfsg.1, running on Linux/x86_64 (2.6.20-15-generic)
X Error of failed request: XF86DGANoDirectVideoMode
  Major opcode of failed request: 136 (XFree86-DGA)
  Minor opcode of failed request: 1 (XF86DGAGetVideoLL)
  Serial number of failed request: 67
  Current serial number in output stream: 67

xawtv was working fine on my old pc (same tv card, dapper and nvidia legacy driver for a Geforce2)

[houstonbofh (leesharp)]

One more on Feisty with nvidia 7xxx graphics. Easy workaround (-nodga) that is not trivial to find. I am surprised that this bug has been around so long with no change.

[Jorge Suárez de Lis (ys)]

What about adding a wrapper script that adds -nodga by default if an nvidia driver is detected?

------------------8<--------------------

#!/bin/bash

unset ARGS
if [ `xdpyinfo -queryExtensions | grep NV-GLX` ] ; then
  ARGS="-nodga"

/usr/lib/xawtv/waxtv.bin $ARGS $@

------------------8<--------------------

[Mihai Niculescu (q-quark)]

I have the same problem and output information just as Philippe Chabbert, except I have Intel P4, Nvidia GeForce 2 MMX, I use nvidia restricted drivers and my Tuner is Kworld

[houstonbofh (leesharp)]

This bug was marked "expired" today. However, since the last activity I have helped several people involved in the zoneminder project using ubuntu with this bug. It is still unpatched, and still a problem. The wrapper script is a viable patch, so why not use it before letting the bug die on the vine?

[Diego Gaustein (gregorovius)]

I agree with houstonbofh, if the solution is to simply add a wrapper script, it should be done before closing this bug... MOTUs? :)

Try: xawtv -nodga

This is a bug in wrapper. Could you apply patch from
http://bugs.debian.org/444447 and tell me if it helps (should work
without passing -nodga).

blokeinlondon, I commented on a similar issue in bug number 111147.

[Tormod Volden (tormodvolden)]

In Gutsy, with an ATI Radeon Mobility X700 and xserver-xorg-video-ati, I also have to use -nodga, otherwise it craps out with
"X Error of failed request: XF86DGANoDirectVideoMode"

[Colin Dean (colindean)]

Running gutsy amd64, nvidia-glx-new on an 8800 GTX and an OnAir HDTV-GT USB capture card. I did read somewhere that the OnAir card wasn't supported, but that was in Edgy. I can't confirm that it's working at all in Gutsy because, well, I don't know how to confirm it other than to use xawtv and lsusb, which shows some information about the adapter (but getting that working is not a goal of this bug)

[Peter Funk (pf-artcom-gmbh)]

7.10 (gutsy): We patched the shell-wrapper script /usr/bin/xawtv:

Replace the line number 12 which contains the following
  if [ `xdpyinfo -queryExtensions | grep NV-GLX` ] ; then
with either
  if [ "`xdpyinfo -queryExtensions | grep NV-GLX`" ] ; then
or more elegant
  if xpdyinfo --queryExtensions | grep -q NV-GLX ; then

This is because the command returns something like
NV-GLX (opcode: 146)
which is invalid as a CONDITIONAL EXPRESSION in bash
without the surrounding quotes.

After that the patch xawtv started without the problem.
This trivial patch should make into the gutsy package.

[Peter Funk (pf-artcom-gmbh)]

Please apply the trivial patch to the shell wrapper script /usr/bin/xawtv, which I described
https://bugs.launchpad.net/ubuntu/+source/xawtv/+bug/76501/comments/18
Thank you very much.

[Tormod Volden (tormodvolden)]

This has been fixed in Hardy, so please file a SRU or backport request if you want it fixed in Gutsy.

[Peter Funk (pf-artcom-gmbh)]

This is my first StableReleaseUpdate Proposal for Gutsy:
1. statement explaining the impact:
  xawtv will not start up due to shell script syntax error (For end users this
  as serious as a segfault on startup in a binary application), if the system
  in question is equipped with a NVidia graphics card and driver.
  NVidia graphics cards are widespread, so many users are effected.
  Without this patch the program is unuable on Gutsy with a NVidia.
2. how the bug has been addressed:
  see https://bugs.launchpad.net/ubuntu/+source/xawtv/+bug/76501/comments/18
  or the description of https://bugs.launchpad.net/ubuntu/+source/xawtv/+bug/157547,
  where Luca Falavigna wrote:
  xawtv (3.95.dfsg.1-7) unstable; urgency=low
  * Applied Tim Connors's patch for xawtv wrapper (Closes: #444447)
3. A patch:
  Since only a single line of code is effected, a patch file is overkill.
  See https://bugs.launchpad.net/ubuntu/+source/xawtv/+bug/76501/comments/18
4. Detailed instructions how to reproduce the bug:
  Try to run xawtv from the menu or the command line on a computer equipped
  with NVidia graphics. Try the command
    xdpyinfo -queryExtensions | grep NV-GLX
  first to make sure the test system is effected by the problem: This should return
  a line similar to this string here: " NV-GLX (opcode: 146)"
5. A discussion of the regression potential:
  Almost no risk, because the patch only removes a trivial shell syntax error.

And if a patch is needed, here is the debdiff.

[tpost001 (tpost001)]

Intersting. I have an ati All-In-Wonder 8500DV (R200) and I am having similar troubles. I got the tv to work once. Don't know what went wrong since. When I try xawtv -nodga I get:

This is xawtv-3.95.dfsg.1, running on Linux/i686 (2.6.22-14-generic)
xinerama 0: 1280x1024+0+0
Warning: Cannot convert string "-*-ledfixed-medium-r-*--39-*-*-*-c-*-*-*" to type FontStruct

I can set the configurator as many times as I want and click save, and I still get the same. The values don't want to stick. I personally think that the program is looking for stuff that was put somewhere else.

[Tharakan (tharakan)]

The wrapper script for xawtv has most of what is here in the discussion, but for people who don't have an NVIDIA card, xawtv still does not start with the default /usr/bin/xawtv script. I have an ubuntu 8.04 and the default error message (without adding a manual -nodga) still gives the same XF86DGANoDirectVideoMode error message.

For me, (contrary to what peter funk added on 29th Feb 2008), the if condition without the double quotes works fine for me.

That is rather than this script (which comes with ubuntu 8.04)...

if [ ! "$XAWTV_USE_DGA" ] &&
   [ -n "`xdpyinfo -queryExtensions | grep NV-GLX`" ] ; then
        ARGS="-nodga"
fi

the following script atleast gets xawtv working for me :

if [ ! "$XAWTV_USE_DGA" ] &&
   [ -n `xdpyinfo -queryExtensions | grep NV-GLX` ] ; then
        ARGS="-nodga"
fi

I am not a shell script expert, and so please pardon my ignorance, if I be talking something out of the blue here.

try to edit /etc/X11/xorg.conf
add this in that file :
