Dell Latitude 7490
The Latitude 7490 is virtually identical to the Dell Latitude 7480 with the exception of an upgrade to Kabylake-R processors (8th gen).
What works
- Basic hardware (display, touchpad, trackpoint, keyboard, WiFi, Ethernet, Bluetooth, audio, hibernation, etc.)
- Keyboard backlight control
- Screen backlight control
- Fn/Hotkeys, including Fn-lock
- Contact SmartCard reader
- Qualcomm Snapdragon X7 LTE Modem
- USB-C (connected to Android phone, was able to charge phone and read files)
- USB-C power delivery
- DisplayPort Alternate Mode for USB-C
- USB-C Display port with D6000 docking station (triple screen with dual 4k works) + power delivery
- Thunderbolt 3.0 (shows up in gnome-settings, works with Dell TB16 dock (Ethernet, DisplayPort @120hz, USB, power delivery, etc))
What does not work
- Fingerprint reader (tracked at https://gitlab.freedesktop.org/libfprint/libfprint/issues/88)
- Presumably NFC
What was not tested
- Contactless SmartCard (probably works since it was detected by
pcsc_scan
- TPM 2.0 (There is an error in the output of dmesg,
tpm tpm0: A TPM error (2314) occurred attempting the self test
)
