Hey! I recall mesa stuck at 3 or 3.3 for compat reasons. You should be able to "upgrade" your GL version with some env variables I think:
MESA_GL_VERSION_OVERRIDE / MESA_GLSL_VERSION_OVERRIDE

See: https://bugs.freedesktop.org/show_bug.cgi?id=96449

Just want to share my impression that power consumption seems to be mainly bios related. My arch install is not tweaked, and I do not run tlp since it kills my wifi. Back when bios ver. 1.1.7 (iirc) was out, power usage reported by powerstat dropped to 3-4 watt. After an upgrade to 1.3.x, I was not able to get this below 6.8 watt, and I experienced rapid battery drain and horrible fan activity. Now with 1.4.4, at least the termperature and fan issues seem fixed, and battery life has significantly improved. Power consumption is down to 5.1 watt idle. Dell is guinea pig'ing us!
Edit: For testing, I now accepted all changes recommended by powertop. With wifi connected and screen brighness relatively low (but not lowest), several open ssh connections and chromium and firefox open, I am down to 4.3 watt again.

Could you (i know it's a pain, but please please!) post pictures of your bios config? It'd be super nice for us to compare!
I'll take pics of mine, reset the bios and try again and see how battery does
I'll update to 1.4.4 as well. Thanks a lot!

Edit: Updated to 1.4.4 and reset BIOS -> Same power

Not sure what's going on with that. That is what you are seeing when you remove xf86-video-intel and switch to native? I'm on a different kernel branch... maybe that's why. The Intel branch is more smoother than mainline (at least for my setup). This is because they push their fixes into their branch first and it takes a few major version bump on mainline (regular linux kernel) to see these changes.

edit: native modesetting... not sure if it is in fact better atm. I don't notice the diff.

I've tried modesetting and removing intel Xorg config and xf86-video-intel completely. After reboot, compiz was slow. Back to SNA for me. I don't have any tearing or artifacts anyway (only the chromium v50+ flickering when maximized).

For those having issues with the USB-C to HDMI output. Per this comment I purchased this simple USB-C to HDMI adapter and now HDMI output works fine for me even at high resolutions.

Per your suggestion I bought the exact same USB-C to HDMI adapter (CableCreation), and I confirm that I am now able to have 4k output. It seems like the Dell's DA200 was to blame after all..

Any information if 2x 4K would be possible with any other adapter ?

If I comment 20-intel.conf and remove xf86-video-intel I can't adjust my backlight anymore (using Cinnamon as DE). If I keep xf86-video-intel but comment 20-intel.conf it works just fine, but the module /usr/lib/xorg/modules/drivers/intel_drv.so will be loaded anyway. Adjusting the backlight using the command line works in all cases.

Anyone else have high CPU usage while watching videos in chromium? I'm seeing 50-100% CPU usage from the "GPU Process".

Booting with 'i915.enable_rc6=0' had no effect.

no diff in power consumption between glamor+modesetting ddx and sna+intel ddx here (KDE/QT desktop since this sort of makes a diff). and in both cases chrome power consumption is rather bad - 3x more than firefox when both are idle, approximately, here... uff.

How good is your wireless connection out-of-the-box? (I use a freshly installed arch with gnome and networkmanager, that's what I mean with out-of-the-box here).

I tested it at 4 different locations each with a different router. And at around 6-7m distance with out any interference in between I lose connection. I did the same tests (i.e. 'watch -n 1 cat /proc/net/wireless' or ping) with several other devices (3 laptops and 3 mobiles) and with these other devices everything works just fine. And it's not due to other problems, such as channels etc.

With ping I have already around 10% packet loss at around 4-5m distance while all other devices have 0%.

I have the developers edition. So the Intel adapter:

lspci -k
---------------------
Intel Corporation Wireless 8260 (rev 3a)

dmesg | grep firmware
---------------------
[    1.577251] iwlwifi 0000:3a:00.0: loaded firmware version 21.302800.0 op_mode iwlmvm

I tried to disable 11n in modprobe and afterwards I tried it in the router settings. Didn't help. Then I tried to disable bluetooth. Only after I disabled it in the BIOS it got at bit better. But only a bit! All other devices have a way wider range.

Do you have similar problems or is your wireless just-fine-out-of-the box?

Did you update the bios to 1.02.10? This last version causes this issue very often

I don't have the dev version. I bought mine at release and it came, for my region, with a broadcom which I replaced with an Intel

3a:00.0 Network controller: Intel Corporation Wireless 7265 (rev 33)
	Subsystem: Intel Corporation Dual Band Wireless-AC 7265
	Kernel driver in use: iwlwifi
	Kernel modules: iwlwifi

From my experience the broadcom was working fine, although getting the drivers was an additional step. The intel is working fine for me too on both default linux-firmware and with linux-firmware-git-iwlwifi(currently used). Just a guess but not many in this thread will have your intel card, *shrug, who knows.

Hmm I thought there must be more people who bought the developers edition!?
So they probably have the Intel card as well, right?

olebowle · 2016-07-27 06:39:54

My Intel 8260 from the dev edition works just fine. I get the same output for lscpi -k and dmesg | grep firmware. The only issue I see is if I stream audio using bluetooth and download something big (with a high datarate) on wifi I get some dropped bluetooth audio packets. The range is good however.

Not sure, most of those who wrote in this thread had the 9350 prior to the dev release so that is why I assumed. I could be wrong.

Thanks olebowle and frank604 for your replies! Seems that no one else has this problem. So I started a new thread:

halka · 2016-07-29 12:00:37

I've installed the 8260 instead of the Broadcom (which started dropping wifi connections after a while) and it's working OK, at least WiFi stuff. However, my BT mouse keeps dropping out, and I had to disable and re-enable BT to get it working again.

e: nevermind, that seems to be an issue with the mouse. Audio keeps chugging along.

Did anyone find a solution to Chrome flickering? The workaround mentioned in this thread doesn't seem to do the trick anymore after about 50.0.2661.102-1.
