[SOLVED] Ubuntu Studio 18.04 GPU config

stampede · 12-03-2018, 08:26 PM

Hi all,

I had this working on a previous install of Ubuntu 17.10, same laptop, I was able to enable and disable my laptop's GPU via the following:

Code:

Enable built in CPU/GPU.
sudo prime-select intel
Enable video card.
sudo prime-select nvidia

Digging into this I noticed this command didn't present my GPU.

Code:

#lspci -k | grep -A 2 -i "VGA"
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)
	Subsystem: ASUSTeK Computer Inc. Haswell-ULT Integrated Graphics Controller
	Kernel driver in use: i915

So knowns are this is isolated to Ubuntu Studio. I really like Ubuntu Studio, so I rather not just reformat. It's actually quite fast on this laptop. The boot speed is ridiculously fast.
My thought is this could be a missing Kernel module? I'm a little out of my zone with kernel modules so any help would be appreciated!

You have Optimus hardware (dual GPU), so you need to complete a more complicated installation process that accounts for the dual GPU. Bumblebee is the generic description of the instructions you need to follow to have a working prime-select command. It's not specific to Studio. Any Bumblebee instruction set for Debian, *buntu* or Mint should be able to get you where you need to go.

When lspci doesn't show what you're looking for, try inxi instead (with -Gxx expressly for video info).

NVidia/Prime driver installation instructions should handle kernel modules without you needing to get directly involved with them.

try this command to see what you have:

Code:

lspci -k | grep -iEA5 'vga|3d|display'

Thanks,

Here are the two outputs I got.

Code:

#lspci -k | grep -iEA5 'vga|3d|display'
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)
	Subsystem: ASUSTeK Computer Inc. Haswell-ULT Integrated Graphics Controller
	Kernel driver in use: i915
	Kernel modules: i915
00:03.0 Audio device: Intel Corporation Haswell-ULT HD Audio Controller (rev 09)
	Subsystem: Intel Corporation Haswell-ULT HD Audio Controller
--
04:00.0 3D controller: NVIDIA Corporation GK107M [GeForce GT 745M] (rev a1)
	Subsystem: ASUSTeK Computer Inc. GK107M [GeForce GT 745M]
	Kernel driver in use: nouveau
	Kernel modules: nvidiafb, nouveau

And then inxi (Great tool never knew about this)

Code:

#inxi -Gxx
Graphics:  Card-1: Intel Haswell-ULT Integrated Graphics Controller
           bus-ID: 00:02.0 chip-ID: 8086:0a16
           Card-2: NVIDIA GK107M [GeForce GT 745M]
           bus-ID: 04:00.0 chip-ID: 10de:0fe3
           Display Server: x11 (X.Org 1.19.6 )
           drivers: modesetting,nouveau (unloaded: fbdev,vesa)

           OpenGL: renderer: Mesa DRI Intel Haswell Mobile
           version: 4.5 Mesa 18.0.5 (compat-v: 3.0) Direct Render: Yes

MrMazda, what do you think is the best way forward? I followed the process for installing NVidea compatibility in Ubuntu and for both recommended drivers things haven't worked.

At first I thought it was Wayland // X Windows compatibility issues, because I'm pretty sure the NVidea drivers only work on X-windows systems. I have the Cinnamon desktop installed on my Ubuntu Studio 18.04 install. But checking for X windows, and trying the included XFCE desktop yielded no solutions.

Code:

# loginctl show-session c1 -p Type
Type=x11

Followed what process exactly? There is more than one path that can be taken with Optimus. What exactly does "haven't worked" mean? If you found and followed Optimus instruction for Studio, *buntu, Debian and/or Mint and couldn't get it working to your satisfaction, maybe you should try the highly praised Archlinux instructions. I can't follow them, or tell whether they or some other might be best, because I don't have the special hardware combination you have. Maybe if you stated which model laptop you have, someone who has one like it could offer more useful help. Maybe the best plan would be go back to 17.10, then do a do-release-upgrade or apt dist-upgrade, which is how I would have proceeded. Fresh installs are fine for those who like cleaning house, but I'm not one of them. I like to take maximum advantage of my already invested effort.

ondoho · 12-07-2018, 02:05 AM

you should start with ubuntu's own instructions if possible (help.ubuntu.com i think).

Reviewing the Optimus installation methods, I think I've fallen into a dependency loop.

Code:

The following packages have unmet dependencies:
 libnvidia-ifr1-390 : Depends: libnvidia-gl-390 but it is not installed
 libnvidia-ifr1-390:i386 : Depends: libnvidia-gl-390:i386 but it is not installed
 nvidia-driver-390 : Depends: libnvidia-gl-390 (= 390.77-0ubuntu0.18.04.1) but it is not installed
                     Recommends: libnvidia-gl-390:i386 (= 390.77-0ubuntu0.18.04.1)
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

MrM, your right I should have done a dist-upgrade rather than re-install. It's a bad habit. While I like the current UbuntuStudio installation. Maybe it's best to go back to vanilla Ubuntu and try again from there. Weighing what's more important GPU vs Low Latency Kernel, I'd say GPU probably wins out.

ondoho · 12-18-2018, 01:13 AM

from that output, i would try

Code:

apt --fix-broken install libnvidia-gl-390

or simply

Code:

apt install libnvidia-gl-390

stampede · 12-18-2018, 08:01 PM

Hey ondoho,

I tried those commands and it comes back with an error. Previously when I ran #sudo ubuntu-drivers devices it recommended the nvidia-340 driver which I installed, after installing it didn't work. I re-ran the command and 390 was recommended. It looks like it's unable to fully clean up the nvidia-340 install.

I've also tried a few purge commands I found, but no luck. At best it brings me back to the dependency message I posted earlier.

my guess would be that you need to uninstall -340 first.

in any case, i recommend to make an effort to find out which is the proper nvidia driver for you.

i also searched your dpkg error, and lo and behold: 2nd search result seems to directly pertain to your problem! seems to, i didn't check.
lesson learned: always search before posting.

stampede · 12-27-2018, 09:17 PM

Thanks for your help ondoho, I did run through a number of ways to uninstall 340 but kept hitting roadblocks. None worked.
While this was all going on I kept getting pop-ups stating system-error. Well, one morning I go to start my PC and it doesn't start... the best I managed to get it is to the grub menu.

I should have taken that moment to practice solving issues in grub, but I took the easy way out and backed up what was on the disk and installed a new O.S. Ubuntu Studio, it's been great but it's me. not you. ..

Anyone stumbling across these posts, sorry there is no solution, Ubuntu 18.04 works great just be careful which version of the nvidia driver you install. I'm going to try my luck with OpenSuse Tumbleweed. I have been running it on VM's for sometime, and it's proved nothing but stable also. Interested in seeing what the desktop experience is like.

You shouldn't expect much detectable difference between VM and hardware with TW (unless you install to BTRFS with snapshotting fully enabled, which I don't do). Also, openSUSE doesn't have a "the desktop experience". It has Gnome(3) and KDE/Plasma to choose from on the main desktop installation screen, but also offers Mate, KDE3, XFCE, LXQt, LXDE, Enlightenment and more as easily additional or alternative options when enabling additional repos either during or subsequent to completing installation.
