Question Ubuntu 21.10 Xorg '/dev/dri/card0: No such file or directory' preventing intel graphics driver use; AIMB-218L SBC, Celeron N6211


Hi,

I'm trying to get Ubuntu 21.10 running on an AIMB-218L SBC. It is most essential that Ubuntu is able to use the hardware to it's full potential for benchmarking purposes, and as it currently stands I am not able to get Ubuntu to use the correct intel graphics driver with the iGPU on the N6211 processor. Disclaimer, I am not particularly well versed in linux...

Below is the Xorg.0.log:

This segment,

[   135.272] (EE) open /dev/dri/card0: No such file or directory
implies to me that it attempts to load the intel driver and runs into an issue.

If I use inxi -Fxxxa, I can see that the intel graphics have not bound with a driver, as it says
Code:
driver: N/A alternate: i915
In addition, I'm seeing 3D performance that is orders of magnitude less than what I would expect from the hardware; confirming, at least, that something is very wrong!

I have searched low and high for a solution to this issue, maybe it's a red herring caused by something else entirely, but any help would be greatly appreciated. Thanks in advance.

Does `ubuntu-drivers list` suggest a driver? If the suggestion from that previous command looks reasonable, try `sudo ubuntu-drivers install`

As far as I know i915 is included in linux kernel. Perhaps (just guessing) there's proprietary firmware needed; when you installed ubuntu did you check the box to allow "3rd party" drivers/software?

Re: DRI / X.org on ATX/ITX boards with a "mobile" CPU

Too little too late, so just for the record:

...I've just had trouble myselfs, making an ITX board with an Intel iGPU work for me. The person responsible for the install picked a recent Ubuntu Mint of all the possibilities, the stock kernel is 5.15.0-82. Interestingly, Debian 11 with a vanilla kernel 5.15.110 does not give me trouble on the same hardware...

My hardware is older, some ITX board with a BayTrail J1900 and an eDP available on a header. And, HDMI and VGA available at the coastline connectors.
I believe the Elkhart Lake on the AIMB-218 would also have eDP available.
So much for similarities.
As for differences in our scenaria, Elkhart Lake is (was at the time of the OP asking) still relatively new and rare silicon, I wouldn't be surprised if the OP had a more fundamental problem = basic support for the Elkhart Lake IGP in the i915 driver.

Anyway in my case, the symptoms were:
Right after installation (not done by me): the kernel would start DRI/KMS and boot to the two external LCD displays attached (via HDMI and DB15 VGA), sending them their respective native resolutions, mirroring the text console output on both of them. Next, the lightdm would appear on both screens, with the logon window only on one of them (i.e. two displays already "side by side"), both displays still in their respective optimal resolutions. After logon, the Cinnamon desktop would start with two black screens (alive in the background).
I tried installing gdm3 and shifting the startup to it, using /etc/X11/default-display-manager. After that, I got two black screens as soon as the GDM3 started = I wouldn't even see the "greeter" (login). From the text-mode FB console boot messages rolling on the screen, straight into black screens as soon as the Xserver would start.
Interestingly, after that, even if I tried to switch back to lightdm, that would not help. Still I'd get a black screen already for the display manager.
Next I tried getting rid of xwayland, to force the thing to use the i915 Xserver/driver directly. To no avail / nothing changed in the misbehavior.
I proceeded to try to investigate, how the display manager and sessions are handled under SystemD, noticed that there was some SystemD scaffolding around Xwindows, and pretty much gave up.

I also did notice the message "open /dev/dri/card0: No such file or directory" in the X.org log file... that's how I got here.

If we added "nomodeset" to the kernel command line, the display manager and the logged-in session would start up just fine, albeit with a default SVGA resolution and 4:3 aspect ratio.
I also noticed several threads, mentioning that Gnome didn't like scaling other than 100%... and found no way to configure that without a working graphical display...

What finally solved the problem on my part:

in the BIOS SETUP, section "Chipset Settings -> North Bridge" or something like that, there's a submenu for the IGP. And, there was an option to enable or disable the internal LVDS (actually eDP, I suspect). It was enabled. I disabled it, saved the config and reset the machine.

Voila, I now had dual-display graphics on the external displays, in native resolution.

I've seen such effects before. On "mobile" platforms, likely to appear en masse in notebooks, the Intel drivers tend to prefer the "built-in notebook display", i.e. TTL/LVDS/eDP. Unfortunately, those interfaces do not have a "presence detect" mechanism in the wiring towards the display. Thus, you may end up in a situation where the OS sends its output on a port that you don't even know exists somewhere inside your "embedded PC" box. This applies to all ATOM SoC's and I suspect all the nominally "mobile-flavoured" CPU's / SoC's that you'd expect to find in a notebook. Including their "embedded" twin SKU's. The "mobile" product family tend to have characteristic BGA/PGA packages, distinct from the "desktop" LGA footprints... and, the Intel graphics drivers can probably distinguish between these categories. Maybe the IGP is somehow earmarked. Interestingly, if you disable the LVDS/eDP in the BIOS, the Intel driver tends to follow suit - at least it did in my particular scenario.

Actually before looking into the BIOS, I've tried addressing this by adding "video=card0-eDP-1:d" at the kernel command line, which interestingly did not help. By trying some kernel cmdline settings for the desired outputs card0-VGA-1 and card0-HDMI-A-1, I noticed that they did affect the kernel framebuffer, but not the Xserver for the i915.
For the record, to get a listing of your IGP's outputs, made available by the kernel-space driver, ls -l /sys/class/drm/* .

I hope this may help someone down the road...
