@iamagrilledguru:matrix.orgiamagrilledguruOk. I'll do this one key at a time then :)22:33:33
@iamagrilledguru:matrix.orgiamagrilledguruHow do I get secureboot ?22:33:52
@iamagrilledguru:matrix.orgiamagrilledguruI saw a package that adds the mok key22:34:08
@qzed:matrix.orgqzedYeah, essentially set up a bootloader with SHIM, then install the package to get the MOK with which we sign the Surface kernel with.22:34:45
@iamagrilledguru:matrix.orgiamagrilledguruIs it as simple as installing it ?22:34:48
@qzed:matrix.orgqzedDepends on the distro22:34:53
@iamagrilledguru:matrix.orgiamagrilledguruSetup a bootloader with shim ? how ?22:35:14
@iamagrilledguru:matrix.orgiamagrilledguru(Debian)22:35:18
@iamagrilledguru:matrix.orgiamagrilledguruWhat is signed and checked ? The kernel and the initrd ?22:36:03
@qzed:matrix.orgqzedI think debian enables secureboot by default, so it should have set that up for you already. You can try that by booting into the distro kernel with secureboot enabled.22:36:57
@qzed:matrix.orgqzedIf that works you'll just have to install the package and follow the instructions it prints when installing.22:37:14
@qzed:matrix.orgqzedThe kernel is singed and checked. I don't think the initrd is.22:37:54
@iamagrilledguru:matrix.orgiamagrilledguruThanks22:41:11
@iamagrilledguru:matrix.orgiamagrilledguruAs it is my debian does not boot with secureboot22:41:38
@iamagrilledguru:matrix.orgiamagrilledguruI want to use my surface as a whiteboard. What do I need to get the pen working ?22:43:03
@qzed:matrix.orgqzedThere's some documentation on secure boot with SHIM here: https://wiki.archlinux.org/title/Unified_Extensible_Firmware_Interface/Secure_Boot#shim22:43:30
@qzed:matrix.orgqzedDebian probably also has some documentation on that22:43:40

What device do you have?
22:43:50
@qzed:matrix.orgqzed * There's some documentation on secure boot with SHIM here: https://wiki.archlinux.org/title/Unified_Extensible_Firmware_Interface/Secure_Boot#shim22:45:52
@iamagrilledguru:matrix.orgiamagrilledguruSurface go22:46:00
@qzed:matrix.orgqzedIIRC the touchscreen/digitizer is a fairly standard HID device on that series. So it should work out of the box. Application support on Linux is another thing though...22:47:54
@qzed:matrix.orgqzedSome applications treat the pen and touchscreen as mouse in a fallback way.22:48:24

@iamagrilledguru:matrix.orgiamagrilledguruI was considering open board22:53:36
@iamagrilledguru:matrix.orgiamagrilledguruIf I want a good expérience i need an app that uses wacom library and then use the one provided by surface linux ?22:54:43
@qzed:matrix.orgqzedWhat wacom library? As far as I know the kernel has standard input events for pens, I don't think there should be any library necessary.22:56:36
@iamagrilledguru:matrix.orgiamagrilledguruI saw a patched wacom library in the surface linux repo and my pen is a wscom one. So I guessed that was needed for pression 22:59:35
@qzed:matrix.orgqzedAh, that's only necessary to help Gnome detect what's a built-in pen display and what's an external pen tablet. It's pretty much only used for rotating the pen and touch input with the screen when rotating the device.23:00:57
@qzed:matrix.orgqzedSo it's only for detection, it doesn't handle any input at all.23:01:30
@iamagrilledguru:matrix.orgiamagrilledguruNoted. Thanks23:07:02
