[Dri-users] GL User Error : * ; without a current contex

[Yann D. <ya...@so...>]

Hi there !

I've got a 3dfx 3000 with 8mo RAM ( rare card ! ) and I cannot launch any GL stuff when DRI is enabled, otherwise my 
system is get frozen ( I got  to log from another box and kill every X process !!)

I use Xfree86 4.2.1 on a i386 debian distrib ( branch unstable ), kernel 2.4.19 (agpgart and everything recommended by 
the doc is in memory) and DRI is enabled :

I installed all libs GLUT, GL, xlibmesa, libglide (pretty old)...bla, bla, bla and I even recompiled the GLide with the 
h3 option (BTW pain in the ass)... I still have the same problem all the time :

Is it a gcc problem? or should I build Xfree myself and give up the debian packages ?

this is what glxinfo with the LIBGL_DEBUG set returns to me :

BTW If I launch gears, It's the same : every GL function reports the same error "without a current context"


Sorry for my poor english and thanks for your feedback !
