thank you so much for the replys

i will chek this tonight when i have time and se if it works to move(link/copy i ment

) that file
and i use nvidia glx 1.0-8756
its quite strange other gl aps works like muppen64 and my gl screensaver also works
edit:
it seems that i dont have libGl.so.1 only as a link to libGL.so.1.0.8756
edit2: the output of cat /etc/ld.so.conf is
/usr/local/lib
/usr/X11R6/lib
/usr/i486-slackware-linux/lib
/opt/kde/lib
/usr/lib/qt/lib
