Bug#613755: base: Laptop does not recover after suspend
 

Hello:

How do I unload the nvidia driver and return to the driver that
originally came with Debian? And, how do I reload the nvidia driver
back again?

thanks

Is the bug reproducible if you don't load the nvidia driver?

Cheers,
Julien

Hi: the bug is reproducible... I've changed xorg.conf from

Section "Device"
Driver "nvidia"
EndSection

to:


Section "Device"
Driver "vesa"
EndSection

and restarted. the problem persists. Even after suspend, the screen
will not turn on with the vesa driver, with the nvidia driver at least
there were the 3 lines displayed as described before.

cheers,

Jorge.

I assume Julien was talking about the kernel module. One way to test
without it would be to remove any nvidia-kernel-* packages you have
installed, in addition to making the change

> Section "Device"
> Driver "nvidia"
> EndSection
>

> EndSection

you mentioned and restarting. Alternatively you can try blacklisting
the module in /etc/modprobe.d and regenerating your initramfs, though
that's not as simple. You can tell whether the NVIDIA driver is
loaded by checking for the line

nvidia: module license 'NVIDIA' taints kernel

in dmesg.

Later, to reinstall the NVIDIA driver, all that should be needed is to
install the nvidia-kernel-* packages you removed before (or remove the
entry in /etc/modprobe.d and regenerate your initramfs, if you chose
that route).

If you find time to do this, please attach full "dmesg" output from
booting with and without the nvidia driver.

Thanks and hope that helps,
Jonathan

Hi Jorge,

Another quick thought.

It would also be interesting to know whether you can reproduce this
with version 3.0.0-1 sid. (If version 3.0 works, then we would look
for the version that fixed it to backport the fix to squeeze.)

Thanks again.
Jonathan
