webcam model and driver

Can someone confirm that the webcam is working? What's the make and model? I was under the impression that the 7390 is quite similar to the 7390 2-in-1 hardware-wise, but the latter doesn't have any drivers for the webcam at the moment (something about needing Intel IPU4). I'm wondering if the drivers for the 7390 can work in the 2-in-1. Shapeshifter (talk) 01:37, 16 January 2020 (UTC)

It is supported out-of-the-box, works with cheese. Driver is uvcvideo?

Video Section

Is the xf86-video-intel package also not recommended for the 7390 (i.e. not 2-in-1 version)? and if so, is it still a problem? Further the instructions for `acpilight` are purely Xorg specific and don't suggest the existence of alternatives. Wouldn't a link to backlight suffice? In which case I suggest to completely omit it from this page. Bloor (talk) 14:22, 3 March 2020 (UTC)

Using xf86-video-intel I had serious (rendering) problems displaying 3D accelerated (OpenGL?) applications, like atom, alacritty, ...
I wasn't able to use xbacklight and had to revert to acpilight, so at least a note might be warranted. Sasvari (talk) 15:06, 3 March 2020 (UTC)

I haven't tried to run a Xorg environment on the machine, so I can't really say much about it. If you say it is a problem and therefore deviates from suggestions by other more general wiki pages, it should stay up. For the backlight, however: I use `brightnessctl` from the community repo without issues. It installs a udev rules script similar to what is suggested on this page. But since all that information is available on the page for backlight, I can't see the reason for us to have duplicate information. Bloor (talk) 16:55, 12 March 2020 (UTC)
