Re: XPS 15 9570 and Ubuntu

What wifi speed are you getting with speedtest.net? I tried killer 1535, intel 9260, intel 8265, and they all work but I can never get more than 25 mbp/s. Even though my 5 year old macbook can get 80 mbp/s, and on the same laptop with windows i can get 80 mbp/s also. Does everyone settle for less optimal speed or not notice it, or is there something wrong with my setup?

Re: XPS 15 9570 and Ubuntu

I have installed Ubuntu 18.10 on the 9570 this evening and this is what I had to do to make it work:

  • First update BIOS and all firmware and drivers in Windows
  • Shrink the Windows partition by 100GB to make room for Ubuntu
  • Reboot and disable Secure Boot, set Thunderbolt Security to "No security" and change disk type from "RAID" to "AHCI" in BIOS
  • Install Ubuntu, but on hitting "Restart Now" the computer freezes and I have to hold the on/off button for 10+ seconds to turn it on
  • On reboot, hit "e" on the GRUB screen and add the following kernel parameters "nouveau.modeset=0 rd.driver.blacklist=nouveau" and hit Ctrl+X to boot with these params
  • On successful boot, add the same parameters to /etc/default/grub and run "update-grub"
  • Install tlp and run "systemctl enable tlp"

The computer now runs nicely with 5-7W power dissipation on light surfing with screen brightness at 30% (aka couch-mode), all keyboard function keys work and I get 6 ms ping + 300Mbit/s up and down from speedtest.net( (basically identical to Windows) using the Killer 1535, no instability issues so far. There seems to be issues with Bluetooth (dmesg says "Bluetooth: hci0: last event is not cmd complete (0x0f)"), I look into that later. I will also try connecting to my TB16 tomorrow at work and report back how that fares.

Update: Everything works on the TB16 except audio and sometimes flaky(?) ethernet.

Update: Bluetooth audio to external speaker works well.

Re: XPS 15 9570 and Ubuntu

Also experiencing unstable ethernet connection with the XPS 15, Ubuntu 18.04 and Tb16 combination. 

At startup ethernet works fine, notification shows 3 connected blocks . But after a while a questionmark shows up in the icon although everything still works fine. Then sometimes the connection fails and won't come back only after rebooting.

Another small issue is that at startup, after about 30 seconds after logging in, the screen goes black for a couple of minutes, 2 to 3 times.

Windows (dualboot) works fine with the thunderbolt, updated all drivers, bios etc.

Anybody a suggestion?

@Aak2: The TB16 ethernet issues are fixed in latest kernel of Ubuntu 18.10. Relevant patch: https://github.com/torvalds/linux/commit/0b1655143df00ac5349f27b765b2ed13a3ac40ca

@oddbjornk  thanks for the reply.

I installed latest kernel available (4.20.3-042003-generic) which seems to have solved both issues. The screen doesn't turn black short after startup any more and the ethernet-connection seems stable as well so far.

Only the icon still shows a disconnected ethernet ( questionmark.png) , no problem, just a bit confusing:.

Make sure that you set the wired connection to 100 Mb/sec - the Gb interface is the one that has an issue.

Make sure that Secure Boot is disabled in BIOS since the drivers are unsigned. I was getting the same error in my case.

Update your kernel to the latest. I'm running 4.18.3, also make sure you have nouveau.modeset=0 in your /etc/default/grub. I had the same issue and the kernel was going into a endless panic trying to sleep the processor cores. Disabling nouveau driver fixed this issue.


Does one still have to append the lines:
nouveau.modeset=0
in /etc/default/grub

Even though one is not using noveau as the graphics driver for the 1050Ti card on the 9570?

Any suggestions getting suspend to work again after S3 was removed from the 1.3.x BIOS? My laptop nearly caught on fire in my backpack earlier this week. I'm now having to shut it down before packing it away l.


Could anyone verify that the computer can be put to sleep without issues on Linux with a running BIOS is higher than version 1.3 (Dell removed S3 after 1.3)?
