Thinkpad t420s - Help with video card on Ubuntu 11.04

Hi,

 

I just purchsed a Lenovo t420s with the following system specs:

 

Intel Core i7-2620M Processor (2.70GHz, 4MB L3,1333MHz FSB) with Intel
14.0" HD+ (1600 x 900) LED Backlit Antiglare Display, Mobile Broadband Ready
NVIDIA Quadro NVS4200M Optimus technology (1GB)
6 GB PC3-10600 DDR3 SDRAM 1333MHz SODIMM Memory (2 DIMM)
128GB Solid State Drive, Serial ATA
Intel WiFi Link 1000

 

It's a really good machine, but unfortunately I am having problems making it work with Ubuntu 11.04. I am a long-term Linux user, a python developer and a supporter of open source software, I cannot use Windows for my purposes and  I need help to enable my vide card drivers.

 

I did a fresh install of Ubuntu 11.04 on my system, and updated all packages. I then installed the ltest Nvidia drivers available, and ensured that Optimus is disabled in the BIOS. After rebooting, nvidia-settings complained that my system isn't configured to rnu the drivers and I must run nvidia-xconfig so I did.

 

After running nvidia-xconfig, my system wouldn't want to run Xorg, and stayed in terminal mode. I checked the xorg log and found this:

 

    (!!) More than one possible primary device found
    (II) Primary Device is:
    (EE) No devices detected.
    
    Fatal server error:
    no screens found

I saw something about this error here : ftp://download.nvidia.com/XFree86/Linux-x86/270.41.03/README/README.txt

 

I am running version 1.7 ov xorg, so this should be fixed. I tried to nvidia-xconfig --enable-all-gpus but it still wouldn't work.

 

The Ubuntu market is now at about 15 million Desktop users, and many more with other Linux distributions, I think Lenovo would greatly benefit by contributing to Ubuntu and helping the software be compatible with the hardware they sell.

 

Could someone please help me with this?

 

Kind regards,

 

Benoit

Re: Thinkpad t420s - Help with video card on Ubuntu 11.04

This will not help, but I recently tried 11.04 on a
Z560 (with just intel graphics) and had no luck
getting it to work. Previous versions work fine.

Is there any other linux distro that will serve your purpose?
