Surface Book 2 #595

Hi there,

i just tried Ubuntu 19.10 on my Surface Book 2. After the clean install all i've done was:

sudo apt-get update sudo apt-get upgrade

and then according to the readme:

sudo apt install git curl wget sed git clone --depth 1 https://github.com/jakeday/linux-surface.git ~/linux-surface cd ~/linux-surface sudo sh setup.sh

the setup script ran without any errors. After booting the surface kernel everything seems to work. Except that the cursor is stuttering heavily and that the system freezes after undocking the tablet part. Only a reboot will help.

What did i miss?

Thx for any help!

I solved these issues by disabling the Nvidia GPU by

makring sure the Nvidia proprietary driver is not installed
adding modprobe.blacklist=nouveau to GRUB_CMDLINE_LINUXDEFAULT in /etc/default/grub_
creating /etc/modprobe.d/blacklist-nouveau.conf, contents:
```
blacklist nouveau
options nouveau modeset=0
```
Not sure if both is needed...

That is indeed working. But how can i use the dGPU and still be able to detach/attach the device? The readme suggests that this should work out of the box with the custom kernel. Or am I wrong?

My SB2 doesn't have the NVidia graphics so I didn't experience that problem. However I did experience a problem with 1 CPU being pegged for "kernel" threads (mostly ACPI stuff) when I upgraded to Ubuntu 19.10 this morning. This resulted in average cpu load of 2.5+ instead of the more typical 0.5 or less. The problem was resolved when I reinstalled surface-linux, but I notice that Ubuntu 19.10 defaults to Kernel 5.3.0-19, whereas surface-linux is still on 5.1.15. To get surface-linux to load I had to go into the advanced section and specifically select it. To save myself that hassle going forward, I changed the grub configuration to always load the last-used kernel instead of defaulting to the newest.

This tool https://github.com/qzed/linux-surfacebook2-mshw0153 helps changing the GPU:
