[SOLVED] Intel Iris Graphics 6100 driver

Toonses82 · 04-03-2016, 04:22 PM

I just installed Debian 8.3.0 with a Cinnamon desktop. Things are working pretty well, but I think I need a graphics driver. The display looks fine, but every time I long in, I get a notification that says I'm running in "Software Rendering Mode." The notification says:
Cinnamon is currently running without video hardware acceleration and, as a result, you may observe much higher than normal CPU usage. There could be a problem with your drivers or some other issue.

I got this same notification on another computer with a Radeon 4500 graphics card. Installing "firmware-linux-nonfree" which includes the appropriate driver solved the problem. However, I don't know what to do on this PC. It is an Intel NUC (NUC5i7RYH) with Intel Iris Graphics 6100. When looking at Gnome System Details, the graphics line says "Gallium 0.4 on llvmpipe (LLVM 3.5, 256 bits)."

Since everything worked fine with Linux Mint, I figure there must be some driver out there that I can install, but a visit to the Intel support page only revealed windows drivers. Can anyone tell me what to look for? I'd prefer something in the Debian repositories.

Thank you,
-Kris

If I remember correctly it is Intel Skylake 5th generation? In Linux+X there are two drivers, one in kernel and the other one in Xorg. Both drivers must be fairly up to date for your graphics. I'm guessing kernel 3.x.x will not do. Anyhow, inspecting dmesg and Xorg log should give good clues what's going on.

Yup, backports driver will be necessary to have a driver for 6th generation Intel processors.

The NUC5i7RYH uses a 5th generation Intel Core i7-5557U processor with Intel Iris graphics 6100. I believe it's a Broadwell chip.

I added the backports repository and successfully upgraded the Kernel. Here's the before-and-after:

Code:

User@Office-NUC5:~$ uname -mrs
Linux 3.16.0-4-amd64 x86_64
User@Office-NUC5:~$ uname -mrs
Linux 4.4.0-0.bpo.1-rt-amd64 x86_64

I rebooted and am still getting the "Software Rendering Mode" message, so it isn't fixed yet. Presumably, something has to happen with the Xorg driver, but it's not readily apparent what I should do. /var/log/dmesg was empty, but /var/log/Xorg.0.log has the following output (truncated for brevity):

Ah, thank you for that information. It seems I'm running Xorg 1.16.4 and I need to upgrade to Xorg 1.18.1. However, looking through Synaptic with backports enabled, I don't see any obvious Xorg upgrade available. How should I go about making the upgrade? Again, I prefer to stick with the Debian repositories if possible.

Not necessarily, maybe upgrading to 1.16.5 will suffice.

You need to see Xorg and Intel driver changelogs to determine what version you need as minimum. https://packages.debian.org/ tells 1.18.2 is available.

I looked through the package lists and it seems that Xorg 1.16.4 is the best I can do in Jessie. Jessie-Backports doesn't offer anything newer. If I look at Stretch, I see 1.18.2 available, but I'm hesitant to use packages untested in Jessie. What do you think? Bad idea?

Emerson · 04-04-2016, 05:45 PM

You may get away building a new intel driver for 1.16.4 by hand. Or you can wait until Jessie gets a new driver. You could open a Debian bug requesting driver upgrade, this should give you at least clear understanding where you stand.

Ok, I think we've identified the problem and how to solve it. I need a newer Xorg, I just need to figure out what approach I want to take. Maybe I'll make that jump over to openSUSE Tumbleweed I've been thinking about. Thanks for the help.

AS far as the idea of using the Stretch Xorg in Jessie, I'd say don't bother. Mixing stable & testing will ALWAYS, given a long enough timeframe, lead to issues.
