/opt/xorg/lib/xorg/modules/drivers/ undefined symbol: xf86SetDGAMode

Question asked by hboetes on May 27, 2013

Since the current xorg has a bug that prevents me to load more than 5 touchscreens -- Yes I have 9 touchscreens for this project -- and since the new version promises to have full multitouch support I installed xorg from git in /opt/xorg.


After changing the symlink in /etc/X11/X to the right binary, adding /opt/xorg/lib to the librarypath, setting up all the symlinks to be able to use the binary driver package from /opt/xorg I got this error:


/opt/xorg/lib/xorg/modules/drivers/ undefined symbol: xf86SetDGAMode


While both Xorg and the driver have that symbol:


$ grep xf86SetDGAMode /opt/xorg/lib/xorg/modules/drivers/ /opt/xorg/bin/Xorg

Binary file /opt/xorg/lib/xorg/modules/drivers/ matches

Binary file /opt/xorg/bin/Xorg matches


I got the feeling I am missing something obvious. I suspect that the fglrx installer script:

links against the default installed version of xorg, and not the version installed in /opt/xorg


How can I do that?
