Hi all,
i am newbie in linux system, i install backtrack on a virtual machine.
while start following some tutorials, i face lot of problems only with nvidia-driver.
for example, if i try to apt-get install chkconfig, the result will be as below:
Reading package lists... Done
Building dependency tree
Reading state information... Done
chkconfig is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.
1 not fully installed or removed.
After this operation, 0B of additional disk space will be used.
Setting up nvidia-driver (256.40-bt1) ...
FATAL: Module nvidia not found.
dpkg: error processing nvidia-driver (--configure):
subprocess post-installation script returned error exit status 1
Processing triggers for libc-bin ...
ldconfig deferred processing now taking place
Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1).

by the way my laptop is lenovo.
can anyone advise please as i since 3 days, i am still in the same place without any move.
i think by mistake i install nvidia-driver, i dont know if i must remove it.

I really appreciate any kind of help.
Thanks in advance
