[12:27] <zx2c4> also, cool https://usercontent.irccloud-cdn.com/file/Ww768WV1/image.png
[13:24] <apw> zx2c4, the wheels are grinding ... as distros go we are pretty quick
[13:26] <zx2c4> Sure sounds it!
[13:26] <zx2c4> Aside from the sausage making process of course
[13:27] <apw> zx2c4, that is as much as anything about multiple checks and balances
[17:05] <zeripath> Hi! I've recently got a HP Omen 15 - it's got fancy keyboard backlights and I was wondering about how I could get them configured from linux without going in to windows
[17:06] <zeripath> I've discovered that they're attached to the ACPI names(?) "\_SB_.WMID.LM02" to get and "\_SB_.WMID.LM03" to set 
[17:07] <zeripath> so if I do echo "\_SB_.WMID.LM02" | sudo tee /proc/acpi/call > /dev/null; && sudo cat /proc/acpi/call; echo;
[17:07] <zeripath> I'll get something that I can read the values for the current backlight settings from
[17:08] <zeripath> but I don't know how to structure the Set
[17:08] <zeripath> I've got the DSDT.dsl 
[17:08] <zeripath> but I don't know how to read it.
[17:09] <zeripath> What's interesting is that the windows client does a very different thing
[17:10] <zeripath> it appears to send commands to 131081 -> (Which maps to 0x20009 which is what these things are mapped to) 
[17:13] <zeripath> can anyone help me or give me some pointers?
[18:32] <sarnold> zeripath: have you seen the acpica-tools package?
[18:33] <zeripath> sarnold: heya! 
[18:34] <zeripath> as in acpiexec?
[18:36] <zeripath> so I used iasl to get the dsdt.dsl - which is where I've found the name
[21:18] <tomreyn> WMI as in (Ms) "Windows Management Instrumentation", IIRC?
[21:19] <tomreyn> and i think someone wrote a client for linux to make these systems work at all.

[21:21] <tomreyn> zeripath: ^
[21:26] <zeripath> tomreyn: Is there a userspace way of querying these?
[21:27] <tomreyn> zeripath: this is all i know really, sorry.
[21:31] <zeripath> So I think hp_wmi_perform_query() might show the way to do it but I'd rather do something in userspace at least to test stuf
[21:32] <zeripath> Interesting the commmand number would be 0x20009 which is substantially higher than the ones in that function
[21:34] <zeripath> The fans would be actually 0x20008 
[21:39] <tomreyn> do you have "ACPI Error: Method parse/execution failed" for something involving \_SB_.WMID? i read 5.2.1 got some patches about HP WMI ACPI table parsing.
[21:42] <tomreyn> actually 5.4.2, namely https://bugzilla.kernel.org/show_bug.cgi?id=201981
[21:42] <ubot5> bugzilla.kernel.org bug 201981 in BIOS "ACPI Error Method parse/execution failed \HWMC, AE_AML_BUFFER_LIMIT - HP Envy x360" [High,Resolved: code_fix]
[21:44] <tomreyn> zeripath: see what you have in sysfs
[21:47] <tomreyn> +   lsmod | grep hp-wmi
[22:07] <zeripath> There are a few of these errors - but I'm fairly certain that linux doesn't know about these LEDS
[22:25] <zeripath> tomreyn: So I don't have hp-wmi as module in lsmod and I can't modprobe it either
[22:27] <zeripath> I'll have another think about this tomorrow. Thanks for your help
[22:28] <tomreyn> hmm should have been a module though?   grep HP_WMI /boot/config-$(uname -r)    tells me CONFIG_HP_WMI=m
