If your display manager is lightdm, you could change it to sddm and see if it helps.
su systemctl status lightdm # shows if it is active. Continue only if it is. systemctl disable lightdm systemctl enable sddm reboot
If not, please show the output of
pacman -Qs nvidia
I installed SDDM, and that works fine. Still a long delay until the desktop is visible after login still, but at least it works now. Thanks! :-)
New install of Antergos XFCE. On clicking the clock to access the login box, the screen goes black. If I login, it remains black.
I’ve tried switching to a TTY and back, restarted X with ctrl-alt-backspace.
If i press ESC, I can see the “An error was detected in the current theme…” requester. Load Fallback does nothing, Load Default brings me back to the login screen, Cancel gives me a grey screen with a white bar in the center.
GPU is a NV GF Go 7300 if that makes a difference.
EDIT: If i wait after logging in, the desktop does eventually load. The login screen remaining black is still a problem though.
It’s missing, because I didn’t think it relevant. :-)
I’ve set up a Win 10 VM with GPU Passthrough. Everything seems fine, apart from really bad mouse lag/stutter on the Win 10 guest.
An identical (test) setup using an image file, instead of the whole SSD, doesn’t have the issue.
I passed the whole SSD to Windows, but think i’ve messed up somewhere. I was expecting Win to see the SSD as it would on bare metal, ie as a Samsung SSD in Dev Manager, and that I could use the Samsung Magician software with it. Instead, it shows up as a QEMU disk, and no matter what settings i try in Virt Manager, or Win, I get terrible mouse lag, making the system unusable.
I made an identical VM setup for testing, using a RAW image file on my Linux SSD (Samsung 850 Pro), and that works fine.
Hi! Not sure which kenel you’re using so i’ll give a generic solution
sudo mkinitcpio -Pwill detect kernel and regenerate initramfs.
Brilliant, thanks! That seems to have done the trick. :-)
Kernel is 4.16.8-1-ARCH in case that matters?
I’ve been working through the guide at:
But I use systemd instead of grub. I’ve activated iommu via editing antergos.conf in EFI, which seems to work ok, after using “dmesg | grep -e DMAR -e IOMMU” to check.
There was no /etc/modprobe.d/vfio.conf present, so i assumed creating it was the way to go, using the ID’s from my setup hardware.
Edited /etc/mkinitcpio.conf as directed
Then there is a link which used to point to Regenerate the INITRAMFS, which has been re-directed elsewhere. So i’m kinda stuck now. Not sure what to search for, especially as anything referencing Grub is probably irrelevant to me.
dmesg | grep -i vfio after a reboot just returns nothing. Not even an error.
Any ideas, or is there a guide that would be more suited to me?
