-== Well known 'error' message ==
-
-'''Problem''':
-
- I was still having a problem running Neverwinter Nights: when I ran the
- program I would simply get the useless 'Error' message, which should be well
- known to those in the NWN Linux community. Why?
-
-'''Solution'''
-
-
- NWN did not work because it requests (since the beta4 client or so) a
- 32bit buffer size (though for no good reason, since it doesn't request
- an alpha size, so 24bit would be enough, which would avoid all the
- trouble...). However, up until very recently (last week in the cvs) the
- X Server wrongly reported all true-color visuals with the root-depth
- (which is only 24bit). This change is somewhere in the server side glx
- code, and ends up afaik in libglx.a (btw if the snapshots don't contain
- libglx.a then that will probably continue to be a problem - never tried
- the snapshots myself, always using CVS). (You can easily check if you
- have the fixed version with glxinfo - the "bf sz" is the value in
- question.)
-
- The reason it works with older XFree86 versions is in old releases the client
- side code (I believe this all ends up in libGL.so?) (also errornously) simply
- ignores minimal buffer sizes asked by an application - thus the app could ask
- for a minimum buffer size of 32bit and just get back a 24bit buffer instead
- if no buffers with 32bit were available. This was fixed some month ago and
- the client now gets back the error it should receive, which broke NWN.
-
- So, if you happen to have a libGL version with the glx visual matching code
- changes but not an X server which reports the buffer size correctly you have
- a problem. If this is still a problem today with the snapshots, then probably
- libglx.a (at least I think that's the correct file) is not included in the
- snapshots.

-== Bad lightening ==
-(maybe this is not the correct place for such a hint, but as there already was a NeverWinterNights section...)
-
-'''Problem:'''
-
-Some part of the scene is not lightened correctly (it is flickering).
-
-'''Solution:'''
-
-Seems that this is a problem with TCL.
-Just set R200_NO_TCL=1 (or use the ConfigurationOptions to disable TCL in newer version) then it should work fine (but with no TCL of course).
-This problem is fixed in current CVS and snapshots, so disabling TCL should no longer be necessary.
