Created attachment 304770 [details] dmesg Hi everynoe, Component: Asus Expertbook B2502CVA OS: Ubuntu 22.04.2 LTS I am having a keyboard issue after installing Ubuntu 22.04 LTS on my Asus ExpertBook B2502CVA, I discovered that the built-in keyboard is not functioning. The keyboard works perfectly under Windows 11, which leads me to reasonably suspect a hardware compatibility issue with Linux. I found that BUG 216158, Bug 216864, Bug 217323 has similarities to my situation, attachment is my dmesg.

Can you try latest mainline (currently v6.5-rc4)? You also need to attach external USB keyboard to your laptop while building the kernel.

I have tried using the 6.5.0-060500rc4-generic kernel today, but unfortunately, the built-in keyboard still not working.
@Bagas any update about this issue?
Could you try if this patches help (and report back to the list) https://lore.kernel.org/all/20230808103335.95339-1-hdegoede@redhat.com/

I don't quite understand how to manually apply the patches mentioned in the link you provided, and I'm concerned about destroying my current development environment. Do you have any recommended kernel version that would allow me to upgrade and test using the mainline kernel?
Can you reproduce this in 6.8.7?

Hello for me the same problem with recent Ubuntu 24.04.1 Kernel 6.8 I tried also Zabbly kernel - no help (6.10.11-zabbly+) dmesg attached br Bohuslav
UPDATE: helpfull link: https://bugzilla.kernel.org/show_bug.cgi?id=216158 adding this section to file drivers/acpi/resource.c helped; if someone could do an official patch it would be great :-| { /* Asus ExpertBook B2502CVA */ .matches = { DMI_MATCH(DMI_SYS_VENDOR, "ASUSTeK COMPUTER INC."), DMI_MATCH(DMI_BOARD_NAME, "B2502CVA"), }, }, how to compile the kernel for ubuntu when someone interested e.g. there https://davidaugustat.com/linux/how-to-compile-linux-kernel-on-ubuntu
Thank you for reporting this. I have submitted a patch adding the DMI quirk for this upstream: https://lore.kernel.org/linux-acpi/20240927141606.66826-4-hdegoede@redhat.com/
Hello, I am having the same issue: Asus ExpertBook B1502CV Keyboard not working for any Debian-based OS (Ubuntu, Lubuntu, Kubuntu, Kali, Debian). But working with Fedora, Windows etc. Could you help in resolving? Thank you.
Hi Nirmal I can only suggest you to do the same as I did - open the link 'how-to-compile-linux-kernel...', but before compiling it, add this section to the file drivers/acpi/resource.c. For me it was the solution btw maybe in advance check if 'B1502CV' is compete boardname - with dmidecode utility br Bohuslav { /* Asus ExpertBook B1502CV */ .matches = { DMI_MATCH(DMI_SYS_VENDOR, "ASUSTeK COMPUTER INC."), DMI_MATCH(DMI_BOARD_NAME, "B1502CV"), }, },
(In reply to Nirmal Chathura from comment #14) > I am having the same issue: Asus ExpertBook B1502CV All B1502CV models should be covered by the kernel after this commit: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/acpi/resource.c?id=158d0f3700fd7190df609a0a61294f29ae698d9e Which is available in recent kernels like Fedora is using and should have been backported to stable kernel series like those used by Debian. Please contact your distribution's kernel maintainer asking them to backport all the recent changes to drivers/acpi/resource.c: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/acpi/resource.c?id=158d0f3700fd7190df609a0a61294f29ae698d9e Note AFAIK most have already been picked up by Greg in the various stable kernel series.
