thanks for your reply I join to this mail the file you were asking for.
but my trouble seems to be resolved. X11 was craching at start. In fact it did'nt start at all. the problem was due to "/usr/X11R6/lib/modules/drivers/mga_hal_drv.o" file. this file was not lincked to something. It was deleted and X11 start again. the solution was found by a friend of mine. I do apologize because I am a roocky in Linux, so I can't help you a lot. Thanks for developping Debian Linux. If you need some more informations, i will try to find answer to your questions. B Riou
