Black screen after installing Cachyos (official version)

Issues & Assistance
1

Hi all,

Rather than necrobumping an existing thread, I have a very similar issue as the one described here: Black screen after installing cachyos (beta) desktop - #4 by ptr1337

I.e. black screen after installing Cachyos from USB. I ran the latest official version of Cachyos. The USB booted fine using the open source drivers. My box is a rather old bird, with an Nvidia 8400 graphics card. However, it runs fine on Nouveau in other Arch-based linuxes (for example Biglinux).

I installed the Gnome desktop.

I ran the bug report script and told it to upload its contents.

Manual startx gives errors, the (I hope) significant ones being,

  • Failed to load Nouveau (does not exist)
  • Failed to load nv (does not exist)
  • Failed to load vesa (does not exist)

And the cursor keep on blinking on an otherwise black screen…

Likely, you need to remove the installed nvidia driver on such a old card.

Check with pacman -Qs nvidia and then check, which nvidia packages are installed.

It’s been a few days but I wanted to report back that the proposed solution worked and I’d like to details the steps for other noobs like myself who also have nvidia hardware that is no longer supported by nvidia drivers.

  • sudo pacman -Qs nvidia to list installed nvidia packages
  • For each package found run: sudo pacman -R [name of package]
  • Some packages cannot be removed due to depencies. For now, just ignore that.
  • sudo pacman -Qs nvidia to list packages that could not be uninstalled
  • Again run: sudo pacman -R [name of package]
  • Some packages can still not be removed. Doesn’t matter, just leave them.

And finally, reboot. After this you should see the GUI running on nouveau.
