Xorg problems on TP T540p

Hi,

I'm fighting with my new T540p and it's GeForce GT730M.
I tried to install nouveau first, now switched to nvidia drivers, but still same problem

(EE) No screens found(EE)

If I try to run X -configure I get
Number of created screens does not match number of detected devices.
   Configuration failed.
(EE) Server terminated with error (2).

What's wrong with it? is 730M not supportted yet? My nvidia version is 334.21 and as I checked on nvidia page they support my graphic card since 331.<something>

Hi,

this is my xorg.conf on T540p. Working like a charm. (Tweaked a bit for that touchpad without hw buttons..)
Drivers installed:

• xf86-video-intel

• nvidia

• bumblebee

I suppose, I've used

# Xorg -configure
# nvidia-xconfig

It should work.

Re: Xorg problems on TP T540p

Whenever using an nvidia card, either use:

nvidia-xconfig

or if you have X working through the vesa driver or whatever, launch nvidia-settings as root and enter a configuration for your display(s) there. Intel setups should automagically configure upon startx. Not sure on radeon cards.

In the future, please post the contents of:

/var/log/xorg.0.log

so that we can help you

Also, you were clearly going for nvidia drivers, but we need to know the specifics of your hardware. Does it have an intel card? Optimus? Can you switch between intel/nvidia/optimus in the bios, and what options have you tried? I happen to know that *most* T540s should have Optimus since my hardware is a T530, but many members arent going to know
