Hey Dirk, I can also take care of sending in the quirk, how would you like to be credited? I'd just add a "Suggested-by: Dirk Holten <dirk.holten@gmx.de>" in the commit if that is fine for you ^_^ (In reply to Christian Heusel from comment #4) > Hey Dirk, > > I can also take care of sending in the quirk, how would you like to be > credited? > I'd just add a "Suggested-by: Dirk Holten <dirk.holten@gmx.de>" in the > commit if that is fine for you ^_^ Dear Christian, thank you for taking care of the fix! The credit is the least that matters for me but your suggestion is of course fine for me. Thank you again |
Created attachment 307004 [details] dmidecode I am following several bug reports for new model laptops of different brands with a non working internal keyboard, in my case the LG Gram Pro 16 2-in-1 (2024) model name 16T90SP. Internal keyboard not working at all (tested up to Kernel 6.11) Adding this model to the quirks list in drivers/acpi/resource.c /* * DMI matches for boards where the DSDT specifies the kbd IRQ as * level active-low and using the override changes this to rising edge, * stopping the keyboard from working. */ + /* LG Electronics 16T90SP */ + .matches = { + DMI_MATCH(DMI_SYS_VENDOR, "LG Electronics"), + DMI_MATCH(DMI_BOARD_NAME, "16T90SP"), fixes the problem and makes the internal keyboard work. I would be thankful if this model could be included in the list in future kernel versions. @Paul Menzel has taken care of several of these requests so I kindly put him in CC for this bug report.
