[Solved] Does anyone have dual screen on AMD R9 270X card?

Postby debianneedstuning » 2018-02-19 03:35

[Solution] /etc/modprobe.d had a file related to the proprietary driver fglrx which had to be removed(or contents commented out).
Apparently, if the file exists in /etc/modprobe.d is it acted upon, even if the driver is not actually loaded.
Once that file was removed, the dual screens were "registered" by the open source driver and the boxen was no longer locked into vesa driver.
xrandr stopped having the gamma error and it was easy enough to use the "display' program to set up dual screens.

The origianl questions was;
The question is specifically for this card.
# inxi -G
Graphics: Card: Advanced Micro Devices [AMD/ATI] Curacao XT [Radeon R9 270X]
Display Server: X.org 1.16.4 driver: vesa tty size: 105x39 Advanced Data: N/A for root
#

debian_version is 8.10 aka jesssie.
Web searching indicates that there might be a solution under V9 aka Stretch, but I want to be sure that I can drive it in dual screen under open source drivers and not revert to proprietary drivers like a previous card.

Long version and background; I'm getting back to a problem that has been on the back burner for over a year and trying to get dual monitors working again.
Previously i've achieve this on a early, different card(Hd7790), but it used the proprietary fglrx drivers, which were a bit bleeding edge and AMD wasn't too responsive on their forum.
Using xrandr just results in the gamma error, which indicates the drivers can not really acess the card.

# xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1920 x 1080, maximum 1920 x 1080
default connected 1920x1080+0+0 0mm x 0mm
1920x1080 0.00*
1280x1024 0.00
1280x960 0.00
1024x768 0.00
800x600 0.00
640x480 0.00

It should list two screens and have labels for the sockets like DPI-0 & DPI-1. It was actuaslly DFP6 & DFP7 under fglrx driver.

I've read the wiki on AMD drivers, but only the vesa driver gives this default screen. None of ATI, Radeon or AMDGPU will load. Xorg just gives a No Sccreen message. Funnly, if there is no /etc/X11/xorg.conf file, then it loads the ati driver, but still gives the default window.

So i've only got one outstanding option to try, but before I enter that world of hurt with other stuff breaking, I wanted to make sure that it was worth the effort.

I don't have a jessie system booted up right now to check, but the man page for radeon or amdgpu will tell you what devices are supported on the version you have installed. You can also use lspci to find the vendor id and search for that in the modinfo output for whatever driver you want to check. lspci -k should list what drivers are available on the system for the device.

Code: Select all
# lspci -nv | grep VGA
00:02.0 0300: 8086:a011 (prog-if 00 [VGA controller])
# modinfo i915 | grep A011
alias:          pci:v00008086d0000A011sv*sd*bc03sc*i*


Searching on the internet for the id string, is sometimes helpful also. If the card is newer than the kernel on jessie, then that would be a clue to why it isn't working the way you expect.

The card and the proprietary driver were released in 2013.
I've now upgraded to stretch and there is the same result.

modinfo says it just isn't supported by the i915 in either jessie or wheezy. Same module anyway.
Seems like I'll have to wat for a hack/update of the module

You misunderstood, the i915 driver is for intel, I only used that as an example because it suits my hardware. Did you find the vendor id of the card? Did lspci -k list any drivers for it?

Are you installing the non-free firmware that the open AMD driver still needs in order to run correctly?

And don't run inxi as root, as you can see from the output, some information is then blocked. It's generally bad practice to run anything as root unless it really requires it.

Thanks, both your posts helped lift the brain fog.

TL:DR I need to look closely at xorg.conf stuff. The system isn't doing the correct stuff auto-magically.

Steve;I used the proprietary stuff about three years ago for a year, but finally became fed up with the bleeding edge nature. and AMds non response to problems, so went back to basic OS drivers and sadly just moved the high graphics stuff to a MS Os system. i'm now have another go at getting abetter card working high quality graphics under Debian.

Long Version; we have a home SOHO and currently there are number of Debian boxen at various versions and I'm the tech support/CTO/3LA/etc.

I usually use screen one of the desktop for local boxen admin and run a root terminal and a user termianl for doing stuff. When I was running the inxi stuff, as you pointed out it doesn't give info to root, but when I ran inxi in the user terminal is went "huh?" as it was for somewhere logged into another boxen that is kept bare mnimal, so brain went inxi is a root only.

So I wasn't aware that the kernel was actually using the "radeon" driver, nor could see any think vga/screen related in the lsmod listing.. The Intel i915 didn't make sense, but there are "intel" drivers in the sound and other modules, so I gave it a try.

Also, web searching indicated that there were(had been?) some problems with utilising this card and a kernel custom reconfigure might be on the cards in the future. meanwhile i've got the disaster of the stretch upgrade to unravel.

End result; rtadeon knows about the card, but xorg.0.log says;
grep EE /var/log/Xorg.0.log
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.

Are you installing the non-free firmware that the open AMD driver still needs in order to run correctly?


The free xorg drivers still require non-free firmware. In Jessie, the package for the stock 3.16 kernel is https://packages.debian.org/jessie/firm ... ux-nonfree

The package for newer kernels in Stretch or jessie-backports is called firmware-amd-graphics.

Do you get error messages in
Code: Select all
dmesg | grep firmware
?

I suspect, based on recent update, that fglrx is still being invoked and incoporated into the kernel.
I've removed the dkms package.
How do I trigger a kernel rebuild to ensure it is no lonker interferring?
