Thanks tom , but actually , all off this doesn't really mean something for me . I was so impatient so i 'm installing a SARGE ( testing ) that migth be more stable : the Knoppix seams diferent from the debian , and because i canot understand nothing , i canot use the help . BUT , i' ll try again , Do you think that the last sarge ( beta4_installer ) can support the help you gave me ?

hi,

this is a nvidia/debian/linux 2.4.x issue, i've spent quite some time figuring out what's wrong and working around it. TLS = thread local storage btw.

i suppose knoppix and debian are similar enough for this approach to work. i use nvidia drivers 5336.

try this first: install linux 2.6 but since that's way from being actually stable, it might not be what you want. this worked for me but broke other things.

another approach: rename the directory /usr/lib/tls to /usr/lib/tls-nvidia or something else. do make sure there are only opengl libs in that dir, then run ldconfig. this should fix the problem, but might prevent your X server to start properly.

then to start the X server, do something like: mv /usr/X11R6/bin/X /usr/X11R6/bin/X.orig

disable setuid by running chmod -s rename /usr/X11R6/bin/X.orig

and replace X with this script:

--

#!/bin/bash

# workaround for nvidia TLS problem # removed setuid bit on the X binary to # make sure LD_PRELOAD works

# this means you cannot start X as a normal # user. (i.e. using startx)

export LD_PRELOAD=
/usr/lib/tls-nvidia/libGLcore.so.1
:/usr/lib/tls-nvidia/libGL.so.1

exec /usr/bin/X11/X.orig $*

Hi all I 'm newbe on pd on linux ( knoppix on hd ) , It was really funny to play with gem and pdp, but i 've installed the nvidia driver and thoses library do not want to be loaded anymore , saying :

tried /usr/lib/pd/extra/Gem.pd_linux and succeeded /usr/lib/pd/extra/Gem.pd_linux: libGL.so.1: cannot handle TLS data Gem: can't load library

tried /usr/lib/pd/extra/pdp.pd_linux and succeeded /usr/lib/pd/extra/pdp.pd_linux: libGL.so.1: cannot handle TLS data pdp: can't load library

tried /usr/lib/pd/extra/pidip.pd_linux and succeeded /usr/lib/pd/extra/pidip.pd_linux: /usr/lib/pd/extra/pidip.pd_linux: undefined symbol: pdp_packet_header pidip: can't load library

Do someone know what does it mean ? i' ve tried to use my old drivers ( nv or fbdev ) but it did not change nothing .

Thanks 3o3
