Re: P50 / P70 linux experiences ?

I was looking at one of those docks but on the US store there was a but of user views saying that they do not work under Linux. I guess it could be them complaining that not all the ports work, or they could have been old reviews and things have changed since then.

@caltinay - what desktop environment are you using?  I've used intel-virtual-output on a w520 recently and got a lot of screen tearing even when moving windows around.  

 

Also, have you tried using the HDMI output on the laptop itself?

@jeh72: xfce4 on Debian stretch. I had tried the laptop's HDMI port directly prior to installing bumblebee, i.e. only running NVIDIA directly. I don't believe the new setup would make it magically work but I should probably test at some stage...

Re: P50 / P70 linux experiences ?

Does any Ubuntu users tried recent kernels? The recent kernel upgrade on Ubuntu 16.04 with kernel 4.4.0-47 broke my dual monitors (one external) on my P50. I then tried kernel 4.8.10, but it's not compatible with the tp-smapi 0.42 power manager. What is the latest working kernel for P50/70 for now? Thanks.

@i2000s: did you try switching to hybrid graphics and back to discrete graphics?

If that trick fixes your dual monitor problem (with the latest Kernel - I am running Fedora 24 with Kernel 4.7.3-200 on my P50 and it works with three displays) it is not an Ubuntu issue but a (known) issue of the Lenovo P50 firmware.

All right, I am reporting back: kernel 4.8.10 works on my P50 now. I uninstalled tp_smapi, virtualbox5.0.24 and then replaced them with acpi_call, acpi-bat and virtualbox 5.1.10. So far, dual monitors, TLP and others work fine for me. The only drawback I have noticed is that the PC power saving status went back to PC2 level from PC3 level on kernel 4.7.0. Maybe this is temporary.

 

I didn't try the discrete/hybrid graphics setting, because the latest kernel works now. One thing is that if I suspend the computer and then come back, I need to use the settings/display to switch back to dual monitor mode. Otherwise, it's one screen mode. I don't why, but it's ok for me.

Re: P50 / P70 linux experiences ?

2016-11-24, 3:16 AM

[I posted this elsewhere, in response to a specific question that pretty much no one has read, and I thought it would be much more useful to people here...]

 

I've been using my new P70 with KDE Neon (which is Ubuntu 16.04 LTS with the very latest Plasma 5 and other KDE and QT packages) for about two weeks now, and it's been an excellent experience! I'm using a very recent kernel, as everyone with a Skylake processor needs to do. In fact, if you're on anything below 4.8, you shouldn't even bother reporting problems until you update your kernel -- support and fixes for so many things are in these latest versions that most or all of your problems are most likely already solved, and you just have to apply the solution. I'm also using the v16 Thunderbolt drivers, which I updated from Windows 7.

 

Here are a few random observations that I've made:

 

  • Using hybrid (Intel+Nvidia) graphics, I had some wonkiness using a second display. This was almost completely solved by switching to dedicated Nvidia graphics in the BIOS. The only problem that persists is that the P70 cannot adjust the brightness of external displays. But that was also the case of my last laptop, a Toshiba, so I assume this is an Nvidia thing. (For the record, I'm using the latest proprietary Nvidia drivers). 
    • What works:
      • Connecting a second display to the HDMI port with an HDMI cable.
      • Connecting a second display to the USB-C/Thunderbolt port through an HDMI adapter.
      • Connecting a second display to the USB-C/Thunderbolt port through a VGA adapter.
      • Connecting a second display to the Mini DP output through a VGA adapter.
      • Connecting a second display to the HDMI port with an HDMI cable and a third display to the Mini DP output through a VGA adapter!
    • What does not work:
      • Connecting a second display to the USB port using a USB to VGADisplayLink adapter. I tried this with the latest drivers from the DisplayLink site, but no luck. 
      • Using both the HDMI and  USB-C/Thunderbolt ports simultaneously results in neither external monitor working.

Some of these problems, like the USB video not working, c ould be because this is still unsupported, but it could also be because the adapter is not working well or is not properly designed. After all, these things are almost invariably cheap Chinese stuff.

 

Other things that work:

  • The webcam works perfectly.
  • The keyboard has three levels of backlighting -- high, low and off. It responds to both the keyboard (FN+Spacebar) or the OS power management settings. 
  • Audio works flawlessly when it works. And it worked perfectly for me for about a week, when it suddenly stopped working both in Linux and at boot time (where I have the BIOS configured to beep on password prompts), but not, strangely enough in Windows 7, which I dual boot to -- it never stopped working there. I tried every imaginable thing to fix the Linux audio for two days, to no avail. And I was sure it had to be a Linux problem, since audio worked in Windows. Then, by accident, my machine froze on boot and I had to do a hard power off, and since then sound works again in Linux and at boot time! This makes NO sense to me, due to the fact that sound worked in Windows at all times.
  • The mic works fine.
  • Wifi and Ethernet work perfectly.
  • Bluetooth works perfectly. In Windows 7, on the other hand, while it can pair with devices, it can't receive audio or send/receive files, meaning Bluetooth is useless there. A big win for Linux!
  • The ExpressCard interface works perfectly with the one card I have, which provides 2 USB 3.0 ports. Note that in Windows 7, the ExpressCard is not even recognized and even with the manufacturer's drives it doesn't work there.
  • The multimedia keys work fine, though a couple (like the magnifying glass on F10) need to be custom set to do something.
  • The card reader works perfectly with SD and SDHC cards. I haven't tried anything else in it.
  • I replaced the ODD with a 2 TB HD using a third-party HD adapter, and it works perfectly.
  • I have a 2 TB Crucial SSD drive in the internal hard drive bay. Flawless.
  • Also, though I've read in many places that the NVMe cards on the P70 can only be up to 512 GB, this is false -- I have two 1 TB NVMe units installed and working perfectly.
  • The track point device works, but there's no way to configure it that I can see.
  • The track pad works very nicely.

 Things that do not work:

  • Fingerprint reader in Linux. Aparently this sends an encrypted datastream that no one has been able to reverse engineer. HOWEVER, you can indeed use the fingerprint reader for pre-boot authentication once you've enrolled your prints through Windows and have configured the BIOS appropriately. I don't know if this would survive uninstalling Windows, though -- that would depend on where the fingerprint enrollment data is stored.

Unknowns:

  • 3G/4G modem. Haven't tested it, nor do I have the SIM or data plan to do so.
  • SmartCard. I have nothing to test this with. 

Random comments:

  • Battery life is what I'd expect with so many drives and such a big screen and Nvidia card always on -- I'm getting 2.5 to 3 hours on a charge, doing normal office stuff and streaming video about half the time. That's with the dedicated Nvidia card! The only tweaking I've done is to install TLP.
  • The P70 has the best keyboard I have ever used! Absolutely stunning.
  • It is back-breakingly heavy, but anyone who wants this level of performance knows what they're getting into and accepts that, I think.
  • It's also quite huge -- it barely fits in a laptop backpack I bought that is for 17.3" devices.
  • The screen (I got the 1920x1080 non-touch model) is good. Bright enough for any indoor conditions. It's the first matte screen I've had and while the colors are less brilliant than on a glossy screen, they're quite good all in all.
  • The speakers are actually fairly decent for a laptop. Music still doesn't sound very good (little bass, excessive mid frequencies), but watching movies is no problem.
  • This is a very quiet machine! Even when gaming, with the Nvidia GPU at or close to 100% (a mere M600M), the fan is barely noticeable, and the temperature stays low.
  • I wish the front edge and corners were a bit rounder -- they're actually quite sharp, with the corners feeling like they've been sharpened. I'm actually considering filing them down a bit with a nail file, as I'm beginning to develop a rash on the bottom of my forearms below the wrists.
  • The bottom access hatch is very convenient, with just 5 screws needed to open it. 
  • The screen hinges could be tighter. It's not a problem now, but I worry that with time it will become one.
  • Do not ever pick this thing up with one hand -- it's massive weight will likely cause damage to some plastic part or another, and it's so heavy that there's a non-trivial chance it will drop from your hand.
  • Why oh goddamned why did you switch the FN and CTRL keys around, Lenovo? There are all kinds of areas you can innovate in -- the positions of keys with years of muscle memory behind them is not one of those areas.

All in all, I'm enormously pleased with the P70 and using Linux on it.

Hey Bazinger, thanks for posting that—it's consistent with most of my experience with the P70. I wa wondering with ODD replacement HDD adapter you used and what the height of the 2 TB drive is—also is it SSD or not?

 

One more thing, with powertop, what's the lowest C-state you've seen?

Re: P50 / P70 linux experiences ?

Hi,

 

I am having problems installing nvdia drivers on Arch. I am an Arch newbie and I am just experimenting, so I tried to install Arch on external USB drive, so I can test it. I used Antergos installer. My DE is Cinnamon. After installation, I tried to install nvidia drivers. First I tried version 375, but after installation, only grey screen with mouse cursor is shown. Then I tried version 340 and result was message “Cinnamon just crashed. You are currently running in fallback mode. Do you want to restart Cinnamon”. I then tried manually to install 367.57 version of drivers but without success. I tried all those options both with Hybrid Graphics and with Discrete Graphics.

I have no idea what to try next, so any help would be highly appreciated.

 

My configuration is: Xeon m1505, 64 Gb, Quadro m2000m, 4k.

Can't help you out on Arch, but on KDE Neon --which is just Ubuntu 16.04 LTS with the latest Plasma 5 added-- Nvidia drivers worked out of the box for me (I have a P70 with an M600M card).

I had one oddity with KDE and dual monitors using the hybrid graphics, so I just switched to discrete in BIOS and that problem fixed itself.

If you're a diehard Arch lover, this will not matter to you, but if you're distro hopping, try something Ubuntu based -- they put a lot of work into getting Nvidia cards to work well.
