xawtv-3.30+xfree-3.3.6: Workaround for "Couldn't find per display information"

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hi,

running xawtv (compiled in Suse-7.0) on my
machine with XFree86-3.3.6 will exit as soon
as you move the pointer with the message:

Error: Couldn't find per display information

The same has been reported by others and is in 
Gerd's KNOWN_PROBLEMS.

WORKAROUND:
- change "config.h" by commenting this out:
  #define HAVE_LIBXXF86DGA 1 
- make (again)

Any X-perts here?

Gunther


MORE INFORMATION:
=================
1) Compiling with dga it you get:

./xawtv -v 2
This is xawtv-3.30, running on Linux/i586 (2.4.1)
visual: id=0x20 class=4 (TrueColor), depth=16
check if the X-Server is local ... **** ok
x11 socket: me=localhost, server=localhost
xfree_dga_init
DGA version 1.1   <----- xfree-3.3.6 has DGA !
...
ioctl: VIDIOCGAUDIO(0,TV,vol=65535,balance=0,bass=0,treble=0,mode=0x1,step=0): ok
PropertyNotify WM_NAME
PropertyNotify KWM_WIN_TITLE
keypad: timeout
PropertyNotify WM_NAME
PropertyNotify KWM_WIN_TITLE
Error: Couldn't find per display information

-> it seems it doesn't bomb when calling a dga function

2)
Note: XFree-4.0.2 will show "DGA version 2.0".
