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 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.
