[Solved] PRIME abused and broken on an optimus laptop

Hey there!

So I broke the PRIME GPU setup and now my laptop will not work with any HW acceleration at all. I tried to follow the official PRIME setup, Optimus with NVIDIA graphics only, Optimus mixed and many more combinations.

In the end, the only way to access GUI is to boot [into black screen], switch to tty and do `startx`.

My setup: Dell G5 with a nvidia 2070.
I'm using lightdm with i3-gaps

Various outputs (while being `startx`ed into i3):

$ xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x46 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 4 associated providers: 1 name:modesetting
Provider 1: id: 0x1ef cap: 0x2, Sink Output crtcs: 4 outputs: 4 associated providers: 1 name:NVIDIA-G0
 $ prime-run glxinfo | grep "OpenGL renderer"                                                                                                                                                                                                                ✔  23:05:48

mkinitcpio.conf

# vim:set ft=sh
# MODULES
# The following modules are loaded before any boot hooks are
# run.  Advanced users may wish to specify all system modules
# in this array.  For instance:
#     MODULES=(piix ide_disk reiserfs)
MODULES=(i915 nvidia nvidia_modeset nvidia_uvm nvidia_drm)
#MODULES=()

# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image.  This is run last, so it may be used to
# override the actual binaries included by a given hook
# BINARIES are dependency parsed, so you may safely ignore libraries
BINARIES=()

# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in any way.  This is useful for config files.
FILES=()

# HOOKS
# This is the most important setting in this file.  The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added.  Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
##   This setup specifies all modules in the MODULES setting above.
##   No raid, lvm2, or encrypted root is needed.
#    HOOKS=(base)
#
##   This setup will autodetect all modules for your system and should
##   work as a sane default
#    HOOKS=(base udev autodetect block keyboard keymap filesystems)
#
##   This setup will generate a 'full' image which supports most systems.
##   No autodetection is done.
#    HOOKS=(base udev block keyboard keymap filesystems)
#
##   This setup assembles a pata mdadm array with an encrypted root FS.
##   Note: See 'mkinitcpio -H mdadm' for more information on raid devices.
#    HOOKS=(base udev block keyboard keymap mdadm encrypt filesystems)
#
##   This setup loads an lvm2 volume group on a usb device.
#    HOOKS=(base udev block keyboard keymap lvm2 filesystems)
#
##   NOTE: If you have /usr on a separate partition, you MUST include the
#    usr, fsck and shutdown hooks.
HOOKS=(base udev autodetect modconf block keyboard keymap encrypt lvm2 filesystems resume fsck)

# COMPRESSION
# Use this to compress the initramfs image. By default, gzip compression
# is used. Use 'cat' to create an uncompressed image.
#COMPRESSION="gzip"
#COMPRESSION="bzip2"
#COMPRESSION="lzma"
#COMPRESSION="xz"

It would be great if I could at least properly use Nvidia GPU

Re: [Solved] PRIME abused and broken on an optimus laptop

In the end, the only way to access GUI is to boot [into black screen], switch to tty and do `startx`.

That doesn't suggest anything is broken here.

Let's start by creating a clean environment. Uninstall optimus-manager and remove all these files

==> /etc/X11/xorg.conf.d/10-nvidia-drm-outputclass.conf <==
==> /etc/X11/xorg.conf.d/10-optimus-manager.conf <==
==> /etc/X11/xorg.conf.d/10-optimus-manager.conf.bak <==
==> /etc/X11/xorg.conf.d/20-nvidia.conf.test <==
==> /etc/X11/xorg.conf <==

Hand yourself a little leeway, https://wiki.archlinux.org/title/LightD … TTY_output and reboot.
If you cannot get into lightdm, move to TTY1, *don't* startx but paste the xorg log,  "cat /var/log/Xorg.0.log | curl -F 'f:1=<-' ix.io"

Re: [Solved] PRIME abused and broken on an optimus laptop

[    12.396] (EE) Screen 1 deleted because of no matching config section.
[    10.887] (==) ServerLayout "Layout0"
[    10.887] (**) |-->Screen "iGPU" (0)
[    10.887] (**) |   |-->Monitor "<default monitor>"
[    10.887] (**) |   |-->Device "iGPU"
[    10.887] (**) |   |-->GPUDevice "dGPU"
[    10.887] (==) No monitor specified for screen "iGPU".

There's a bogus configlet around:

ls -R /{etc,usr/share}/X11/xorg.conf*
grep -i igpu /{etc,usr/share}/X11/xorg.conf*

Edit: also

lsinitcpio /boot/initramfs-linux.img|grep nvidia

and see https://wiki.archlinux.org/title/NVIDIA … de_setting (the kernel parameter isn't there either)

You're right, I forgot to run `grub-mkconfig`, now it's there.

Re: [Solved] PRIME abused and broken on an optimus laptop

Please post it first, but

You're right, I forgot to run `grub-mkconfig`, now it's there.

This is probably far more important.

Re: [Solved] PRIME abused and broken on an optimus laptop

head -n 999

You can just "cat" them…

/usr/share/X11/xorg.conf.d/10-nvidia.conf looks like a (tampered with?) leftover from optimus-manager to use the nvidia chip as primary GPU while the server references the intel chip.
Get rid of that.
The output redirection in the xinitrc likely deals w/ this (and you probably don't have the same redirection triggered in your lightdm scripts)

If you always want to use the nvidia chip, we'll deal w/ that afterwards, but for now we want a stable baseline.

I rebooted the system afterwards, but no change visually

There's however a very significant change in the Xorg log - the nvidia chip is readily available now…

Yup, but doing it this way includes the filenames

It works! Now I can successfully boot into lightdm greeter and everything seems to be working afterwards. Thank you!

If you always want to use the nvidia chip, we'll deal w/ that afterwards, but for now we want a stable baseline.

I'd prefer to have a proper setup, with intel being the primary GPU and using `prime-run` to run games etc., but I can try figuring it out on my own, you already helped me a lot!

Thsi should be the status quo anyway - you can confirm it w/ "glxinfo -B" and "prime-run glxinfo -B" which should reveal the intel chip in the first and the nvidia one in the second instance.

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

I see that both still use Nvidia, what kind of method would you recommend to switch the cards? Not optimus I guess?

Re: [Solved] PRIME abused and broken on an optimus laptop

Yup, the nvidia chip is preferred and it's what has the output attached, so you'll need https://wiki.archlinux.org/title/PRIME#Reverse_PRIME (config and xrandr stanza, make sure to use the correct provider labels)
For lightdm you'll then need the display-setup-script to be set, https://wiki.archlinux.org/title/LightD … ng_monitor

Any idea why 

lspci | grep VGA

would only see the Nvidia GPU?

Re: [Solved] PRIME abused and broken on an optimus laptop

What's the unfiltered output of "lspci"? Xorg certainly detects two cards.

Re: [Solved] PRIME abused and broken on an optimus laptop

Sorry for not getting back to you, I wasn't much at the PC.

My bad, `lspci` doesn't have `VGA` text in its output for Intel as it calls it "Display controller". Either way, for now my PC works good enough for me and I will consider this resolved. Thank you so much for your help!
