<p dir="ltr">Hi,</p>
<p dir="ltr">Sorry for your troubles.</p>
<p dir="ltr">Unfortunately that's expected if you have an optimus system, that's how they are wired up. Install bumblebee-nvidia and primuslib and you will be able to use the discrete card on demand via the optirun command.</p>
<p dir="ltr">> so I install nvidia-xconfig and generate the xorg.conf, but when I reboot I can't get into the desktop with "device not found" error, then I add <br>

<p dir="ltr">Sorry, but that was a unfortunate move :-) xorg.conf is autogenerated these days, we should really put a warning or something. Anyway that's an expected outcome, you can't simply use the Nvidia drivers as the main driver on an optimus system, they are not wired that way. Bumblebee is the correct solution.</p>
<p dir="ltr">I'd suggest to clean up the xorg conf and try again with bumblebee and drivers from the repository. 352.79 in backports/testing/unstable is very stable and supports all hardware supported by 355 and 358, so no need to use those.</p>
