[Résolu] erreur overlay apres install drivers fglrx

salut aux utilisateurs de ubuntu (ubuntu, c'est bien),

j'ai installé les drivers propriétaires ATI comme expliqué dans ce post :http://forum.ubuntu-fr.org/viewtopic.php?id=2487 (très bon, dit en passant)

Ca a fonctionné, mon score à glxgears a explosé .
Mais lorsque j'utilise TVTime ou XawTV, j'ai des problèmes .
TVTime plante immédiatement :

collomb@caribou:~$ tvtime
Running tvtime 0.9.15.
rtctimer: Cannot set periodic interval: Permission denied

    Failed to get 1024 Hz resolution from your RTC device.  High
    resolution access is necessary for video to be smooth.  Please
    run tvtime as root, set tvtime as SUID root, or change the
    maximum RTC resolution allowed for user processes by running this
    command as root:
        sysctl -w dev.rtc.max-user-freq=1024
    See our support page at http://tvtime.net/ for more information.

Reading configuration from /etc/tvtime/tvtime.xml
Reading configuration from /home/collomb/.tvtime/tvtime.xml
xvoutput: No XVIDEO port found which supports YUY2 images.

*** tvtime requires hardware YUY2 overlay support from your video card
*** driver.  If you are using an older NVIDIA card (TNT2), then
*** this capability is only available with their binary drivers.
*** For some ATI cards, this feature may be found in the experimental
*** GATOS drivers: http://gatos.souceforge.net/
*** If unsure, please check with your distribution to see if your
*** X driver supports hardware overlay surfaces.
collomb@caribou:~$

Quant à XawTV, il ne fonctionne que si je le mets en "grabdisplay" à la plaçe de "overlay" :

collomb@caribou:~$ xawtv
This is xawtv-3.94, running on Linux/i686 (2.6.10-5-386)
WARNING: v4l-conf is compiled without DGA support.
WARNING: couldn't find framebuffer base address, try manual
         configuration ("v4l-conf -a <addr>")

ioctl: VIDIOC_OVERLAY(int=1): Invalid argument

Re : [Résolu] erreur overlay apres install drivers fglrx

J'ai trouvé la solution sur le site de tvtime

1. tvtime not starting when using the Radeon FireGL drivers

With the Radeon FireGL drivers, the user has the option of having OpenGL use an overlay surface, giving 3D graphics without tearing, or video overlay surfaces for multimedia players. This can be set in the Device section for the fglrx of your /etc/X11/XF86Config-4 using:

    Option  "VideoOverlay"       

or

    Option  "OpenGLOverlay"     

To use tvtime, you MUST select VideoOverlay instead of OpenGLOverlay. The tvtime bug report on this is bug 787142.

il faut donc ajouter la ligne

Option  "VideoOverlay" "on"

dans /etc/X11/xorg.conf. Ce  qui donne chez moi

Section "Device"
	Identifier	"ATI Technologies, Inc. Radeon 9200 (RV280)"
	Driver		"fglrx"
	BusID		"PCI:1:0:0"
    Option      "VideoOverlay" "on"
EndSection

et voilou.

Astuce qui fonctionne aussi sous Breezy

En passant par le post qui explqiauait comment installer les drivers ATI simplement, je me suis retrouvé à plus pouvoir afficher TVTIME:
une petite ligne dans Xorg.conf et voilà...
