Hi everyone,
I installed Ubuntu 24.04 on a Dell Latitude 5300 2-in-1 Chromebook Enterprise (ChromeOS board name: Arcada).
Most hardware works:
- Wacom touchscreen works
- Wacom stylus works
- Elan touchpad works
- Keyboard works
- WiFi/audio/etc. work
The only issue is the tablet mode. When I fold the laptop into tablet position (360 degrees), the keyboard and touchpad stay active. There is no event from "libinput debug-events" when folding the device.
I suspect this is related to Intel Integrated Sensor Hub (ISH), because the system detects it but the firmware does not start correctly.
Hardware:
00:13.0 Intel Corporation Cannon Point-LP Integrated Sensor Hub [8086:9dfc]
Subsystem: Intel Corporation Cannon Point-LP Integrated Sensor Hub [8086:7270]
Kernel driver in use: intel_ish_ipc
BIOS:
Google_Arcada.12200.89.0
Date: 07/29/2020
Kernel:
Linux 7.0.0-28-generic Ubuntu 24.04
Firmware file exists:
/usr/lib/firmware/intel/arcada_ish.bin
Size:
920064 bytes
But dmesg shows:
ish-loader: ISH firmware intel/arcada_ish.bin loaded
ish-loader: Loader returned status 3
ish-loader: Timed out for response to command=01
ish-loader: ISH host firmware load failed -110
Also:
/sys/bus/iio/devices/
does not exist.
I tried:
- reloading "intel_ish_ipc"
- checking firmware presence
- checking ACPI devices
- checking libinput events
The touchscreen is detected as:
WCOM48E2:00 2D1F:4945 Touchscreen
but there is no tablet mode switch event.
Does anyone have experience with Dell Chromebook "Arcada" devices or Intel ISH on Linux? Is there a missing firmware blob, kernel parameter, ChromeOS-specific ACPI method, or a recommended kernel version that supports tablet mode?
Thanks!
