 AN!Wiki :: How To :: Thinkpad P70

Adventures in getting Linux supported on the Thinkpad P70 with the Nvidia M600M .

  • So far, Fedora 23 is a bust.

CentOS 7

 Note: This is based on Dedoimedo's tutorial, except updated for UEFI and using proper systemd calls.

BIOS;

BIOS

Disable Secure Boot, enable UEFI booting and use discrete video.

Install the OS

  • Press e and add nomodeset i915.preliminary_hw_support=1, then press 'ctrl + x' to boot.
 Note: XFS appears to hang when trying to sleep CentOS 7 on the EPEL 4.4.2 mainline kernel used here. For now, use 'ext4'.
Note: The Wireless NIC will not be available during the install.

Install CentOS 7 using the ext4 filesystem and install the "GNOME Desktop".

Preparing the OS

Update the OS and reboot. 

yum -y update
reboot

Install ELRpo kernel-ml

The wireless card won't work on the stock kernel (yet), so we'll install the ELRepo mainline kernel. 

rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm

Make the mainline kernel the default kernel. 

grub2-set-default 0
Note: Don't reboot yet.

Blacklist 'nouveau'

 Note: We're going to black-list the nouveau drivers for the binary Nvidia driver install. We need to reboot now to load the new kernel, so we will blacklist the driver now.

Blacklist nouveau in grub. 

cp /etc/default/grub /etc/default/grub.original

Change the GRUB_CMDLINE_LINUX line to: 

GRUB_CMDLINE_LINUX="rd.lvm.lv=darkmatter_vg1/root i915.preliminary_hw_support=1 rdblacklist=nouveau"

If you see a second Intel entry, you're still in 'Hybrid' mode.

Install Dependencies

Make sure dependencies are installed: 

yum install gcc make

Make Sure the Running Kernel and the Kernel Source Match

Verify that the active kernel matches the kernel source: 

uname -r

4.4.2-1.el7.elrepo.x86_64

rpm -q kernel-ml-devel

kernel-ml-devel-4.4.2-1.el7.elrepo.x86_64

Here, the version is 4.4.2-1 for both, so we're ready. If not, fix it before proceeding.

Download the Latest Nvidia Driver

 Warning: The binary driver will only work on the kernel it was compiled against! If you update the kernel, you will need to repeat the following steps to get your GUI back.

Download the latest Nvidia drivers for the Quadro M600M:

Product Type: Quadro
Product Series: Quadro Series (Notebooks)
Product: Quadro M600M
Operating System: Linux 64-bit
Download Type: Linux Long Lived Drivers
Language: English US

Save the file (NVIDIA-Linux-x86_64-361.28.run in this example) and make sure it is executable. 

chown 755 NVIDIA-Linux-x86_64-361.28.run

-rwxr-xr-x. 1 755 digimer 84M Feb 17 20:47 NVIDIA-Linux-x86_64-361.28.run

Install the Driver

 Note: The next steps are much easier to do over SSH.

Switch to the command-line only (what used to be init 3): 

systemctl isolate multi-user.target

PolicyKit daemon disconnected from the bus.
We are no longer a registered authentication agent.

Run the script to install the Nvidia drivers. 

./NVIDIA-Linux-x86_64-361.28.run

For reasons not yet solved, some conditions (booting, etc) will leave you with a black screen.

Intel Wireless 8260

Currently, there is a problem with the v4.4.2 kernel where the wireless comes up, but it takes a while. You can see this in dmesg;
