Install hangs with radeon R5 230 as primary output video card

Hello all,
in bios I have selected the pcie slot in which the radeon R5 230 is plugged in. As seen in this screenshot, the install hangs at this point: https://imgur.com/YONf33t
As seen here: https://en.wikipedia.org/wiki/List_of_A … sing_units
the card is a caicos and therefore should have radeon support: https://www.x.org/wiki/RadeonFeature/

If I switch the pcie slot in bios to the nvidia card I have, the usb install environment works with no problems.
I'm using legacy mode (no uefi) since my board's uefi bios support lacks for video cards with larger memory sizes (which my nvidia card has).

Card appears to work properly within windows when I boot into windows with it

The linux install I used is: archlinux-2019.02.01-x86_64.iso

Any help would be greatly appreciated!

Greetings,
DF

Re: Install hangs with radeon R5 230 as primary output video card

Sometimes triggering uevents can take a considerable (like minutes) amount of time, how long did you wait ?

If I switch the pcie slot in bios to the nvidia card I have,

What brand and model is your motherboard and which bios setting are you changing ?
What processor and does it have an integrated gpu ?

My motherboard is: gigabyte GA-X79-UD5
https://www.gigabyte.com/Motherboard/GA … -dl-driver
I have bios F12, F13w didn't work with my nvidia card in either uefi or legacy mode. The BIOS setting I am changing allows you to set a pcie slot used for the graphics being used. You can see the setting called "Init display first" in a screenshot on page 51 of chapter 2-5 entitled "BIOS Features" in the manual:
http://download.gigabyte.eu/FileList/Ma … -ud5_e.pdf

The paragraph about the setting reads as follows from the manual above:
Init Display First
Specifies the first initiation of the monitor display from the installed PCI graphics card or the PCI Express
graphics card.
  PCIe Slot1
Sets the graphics card on the PCIEX16_1 slot as the first display. (Default)
  PCIe Slot2
Sets the graphics card on the PCIEX8 slot as the first display.
  PCIe Slot3
Sets the graphics card on the PCIEX16_2 slot as the first display.
  PCI
Sets the graphics card on the PCI slot as the first display.

Here is the CPU I have:
https://ark.intel.com/content/www/us/en … 0-ghz.html
As you can see, onboard graphics is not possible/offered by this chip.

What are your thoughts on the theory that on that pcie slot 1 (which is currently used by the nvidia card) there is some setting not fully being changed over from pci slot 1 to pcie slot 3 when using that "Init display first" setting?

I also tried installing fedora and waited 10min before giving up. I made it as far as this background image, but with no menu or windows -- just a mouse: https://zdnet3.cbsistatic.com/hub/i/r/2 … dora29.png

Thanks for your suggestion, I will wait longer with the arch install again and report back again...but not holding my breath though :-/

Have you tried simply taking out the Nvidia card? Not to sound condescending, but it's quite an obvious troubleshooting step to take - it wouldn't surprise me if Linux tries to activate both cards and barfs on it.

An option that doesn't involve taking out the card is to blacklist the nouveau module.

Re: Install hangs with radeon R5 230 as primary output video card

The option that you suggested without taking out the video card worked very well.
I was able to hit the tab key while booting off the arch install on my usb key and enter "module_blacklist=nouveau" as a kernel parameter.

Thanks again to both of you for your help!
