Description Stefan Dirsch 2004-07-14 07:07:02 UTC

I just updated to current CVS and recognized that the (binary-only) 
nvidia driver for Linux no longer works with that version. Error 
messages are:

unresolved!

I verified that the nvidia driver still works with CVS of 04-06-27, 
but is at least broken with CVS of 04-07-07 and later. Simply using 
the Xorg binary of 04-06-27 fixes the problem.

Meanwhile it could be reproduced.

Hi 

I built xorg CVS this past weekend and got the same error's trying to 
use nvidia's driver. I'm not signed up for the mailing-list but feel 
free to forward this email there.

I can also confirm nvidia driver doesn't work with the cvs build from 07-11 I built.

This can be very easily changed back, which I have now done.  In the 
future, if you find other areas where the code has caused ABI problems, 
please let me know and I will fix the problems.

I still need to investigate if this really fixes the problem. Should be done 
in some hours.

Just verified. The reverted change fixes the problem. :-)
