[Libdlo] undefined symbol: xf86InterpretEDID

[Alexander Todorov]

Hi folks,
I've followed the instructions from the MultiSeat wiki page and I get an error
when X is loading the displaylink_drv.so library.

Under /dev/usbseat/5 I have a groupping of display, keyboard and mouse. Running
the X command from the usbseat.sh script by hand gives:

# /usr/bin/X -br :5 -audit 0 -nolisten tcp -novtswitch -sharevts -config
/tmp/tmp.vvsaUb3519

/usr/bin/X: symbol lookup error:
/usr/lib/xorg/modules/drivers/displaylink_drv.so: undefined symbol:
xf86InterpretEDID

The displaylink_drv.so comes from xf86-video-displaylink-0.3 which, IIRC
compiled without errors on my machine.

This is on line 300 in displaylink.c :

    299         ioctl(fPtr->fd,DL_IOCTL_EDID, edid);
    300         DLMonPtr = xf86InterpretEDID(pScrn->scrnIndex, (Uchar *) edid);
    301         xf86PrintEDID(DLMonPtr);


Any idea what's going wrong? In the mean time I'll continue googling.

Regards,
Alexander.
