I was having the same issue on my P50 back in April. But everything is working now. I don't know about P70.

Awesome.  Do you know what changed to fix the problems?  What issues did you have?

Everything worked out after a patch on Gnome in May and maybe on Unity as well. Also some fixes on the Linux kernel from 4.6-rc and above.

Re: P50 / P70 linux experiences ?

I currently have the P50 runing with Ubuntu 16.04. I have gotten the external monitor working with HDMI directly and mDP to HDMI. How I got things working is to go to additional drivers and install the Nvidia proprietary drivers. I rebooted and went into the BIOS and changed the video to discrete graphics. Once I booted up I was able to my built-in display with 2 other displays (total of 3) working.

 

With all that being said I am having some issues when I lock my screen. After waking up after a screen lock the HDMI display fails to come back on. I solve this by restarting the computer. The display connecting straight to HDMI is being routed through a DVI to HDMI adapter. Not sure if that is causing a problem or not. I will have to continue mess with it and let you all know if I have any progress.

 

Has anyone had similar issues?

Tried a P50 (Xeon, ECC, 4k screen) in late February with Fedora 23, and had issues with video (unless I used nVidia-only, the bottom of the screen was off the screen) and with suspend (the laptop locked up early enough in the process that nothing was even logged).

I get the impression that those issues have been resolved in the interim, and that about all that's "problematic" is multiple monitors (if only you could get the P50 with just Intel video, things would be awesome, as they are with the X1 Carbon).

I'd like to use Fedora 24 and I'd not mind confirmation that people are having success with the Xeon & 4k screen.

Hi i2000,

I already posted in this forum a step-by-step description. Please mind that it was used for 4.1 kernel.

For the newest, 4.7 kernel the "ultimate bumblebee" process stacks at the step, when nvidia-bumblebee tries to compile the nvidia driver (4 kernel objects). There is a workaround for that, where you have to modify the source codes - 3 lines all together - and finish this step manually.

After that it works robust.

The only reason why I upgraded from the 4.1 higher than 4.3 (i.e. 4.7) is that I use virtual machines and their full screen support was buggy with the preliminary hardware support of the former kernels.

So if you use a kernel that is older than 4.3, my post should work for you as well for bumblebee installation.

Otherwise come back to me, I will post here the modifications for newer (e.g. 4.7) kernels.

Hi jeh72,

Please find my earlier post with step by step instructions. The only constraint is that it can be used up to 4.6 kernel, but with the latest there are additional steps.

Great! I may try it after my traveling.

Re: P50 / P70 linux experiences ?

Hello all,  I've finally had some time to try getting the discrete graphics to work (on the P50) and it has been a mess.

 

It seems like a number of other users have had success using prime-select with the propriatory drivers on Ubuntu 16.04.  However, I just simply cannot get it to work.  I was able to get bumblebee and optirun working but for the time being I'd really prefer to use prime-select (most of the time I only need to use intel, it's not a big deal to occasionally log out when I need to use a projecter).

 

I've tried a number of things but I'm always running into problems such as:

- Log in loop after prime-select nvidia (problem loading glx)

- Kernel module signing problems (despite signing exactly the same way as I had before with no problems)

- Black screen when booting (error driver ebridge is already registered)

- Jockey just doesn't seem to work, it installs but never switches to nvidia correctly.

 

Obviously I can't expect much help solving this very diverse list of problems (which result from different attempts after clean installs).  But what I'm hoping is that some Ubuntu 16.04 users might post what kernel, nvidia driver, etc. version you are currently using successfully and what steps you took to install, blacklist nouveau, etc.

 

I'm at clean install stage now, and it appears that the current stock kernel and nvidia-361.42 are not playing nicely.  Given that so many users seem to be having no problems, it'd be great to save myself some time and just copy what has worked for other users.

 

Thanks in advance for any help.

Okay, I was able to get the nvidia drivers working. However even with BIOS set to Discrete only, I still can't use my hdmi port. Guessing it might be this (https://support.lenovo.com/us/en/solutions/SF16-T0051) non-linux specific bug, but I'm wondering how other posters earlier in this thread were able to use hdmi?
