can't boot from dedicated gpu after -Rns systemd-vgaswitcheroo-units

schueni1 · 2016-12-15 12:54:17

Hi,
I installed the systemd-vgaswitcheroo-units as suggested in the setup guide for my machine:
https://wiki.archlinux.org/index.php/MacBookPro10,x

It does what it should do. My machine now always boots with the internal intel gpu.

Now I uninstalled it and tried to boot from again from the dedicated (nvidia) gpu. I executed the command:
cd /path/to/gpu-switch
./gpu-switch -d

and tried to reboot, but it always gets stuck, if i don't force to boot it from the internal graphics card with the command:
./gpu-switch -i (executed from a bootable usb-drive)

Is there any way to solve this without reinstalling Arch?

Are you using xf86-video-nouveau or nvidia proprietary drivers ?

schueni1 · 2016-12-16 14:29:26

I'm using the open source driver. I think it is called nouveau.

Yes, it is.

Try switching on the discrete card again, rebooting and waiting about 2 minutes .

Does CTRL + ALT + Fn work to give you a tty ?

If not, reboot and use "journalctl -b -1" to get the logs from the problem boot .

These are the errors I get when I try to boot with the dedicated gpu. I also get other errors, but they are the same as with the integrated gpu. So I assume the rest is not important.

Looks like we'll need more info to continue.

please boot to multi-user.target (see systemd wiki page) .

post /etc/mkinitcpio.conf , lspci -k and dmesg (this may be very big, better use a pastebin site.)
