Besides the size difference, which one would you choose for OpenRGB on Arch Linux? Had a Keychron K8 Pro that I didn't get to work. Now it died, so have to replace it. Price wise they're 50 for the Alienware (new) and 75 for the Razer (open box, as new). Please help me decide. Thanks!
Update if anyone finds this thread later: I went with the Razer BlackWidow V3 and also got a Basilisk V3 to match it and they work very well with OpenRGB, I would definitely recommend them! I’m slightly annoyed by the green switches on the keyboard (sound and the feeling when typing) but that’s of course unrelated.
I would recommend the Razer. Razer devices are some of the best supported in OpenRGB as they all use one of a few different protocols and we have extensively tested all of them. If it isn't already supported it should be easy to add. I personally have no experience with the Alienware keyboard but have plenty of Razer devices.
If I may ask you another question regarding support: I have a Corsair Capellix H115i cooler, 2x ML140 RGB PWM fans and 4x LL120 RGB PWM fans. They are all connected to the commander core that came with the pump. OpenRGB detects the commander core and for a brief moment I was able to control three of the smaller fans (another one the same model not however) but now I can't control anything. Are these devices not supported or is there something I can do to make it work?
I'm not familiar with the Commander Core specifically, but did you set the zone sizes properly? You need to tell ARGB controllers how many LEDs are attached to each channel in order for them to work. You can edit the size by selecting the Zone in the Zone box and clicking Edit.
I'm not sure if another driver could be overriding it. There is a corsair_cpro driver in Linux that prevents OpenRGB from working with a Commander Pro but I don't know about Commander Core. Does it even get detected? Tried running OpenRGB as root?
