Notebook Lenovo V15 G4 IRU

Recently bought Notebook Lenovo V15 G4 IRU Business Black from https://www.alza.cz/EN/lenovo-v15-g4-iru-business-black-d7988707.htm?setlang=en-GB

Main features:

  • 8 core CPU (12 threads - 4 cores are single threaded another 4 cores are multithreaded), 13th Gen Intel Core i5-13420H
  • 16GB RAM
  • GPU: Intel Raptor Lake-P [UHD Graphics] (note: higher Iris Xe mode requires dual-channel memory).
  • 512GB NVMe SSD (SK Hynix)
  • LAN: Realtek RTL8111/8168/8211/8411 PCI Express Gigabit Ethernet driver: r8169

Important hotkeys:

  • F2 to enter setup
  • F12 to show boot menu

Note: in setup - only local HDD OS are shown (not USB HDD), however when you use F12 for boot menu you will normally see also bootable OS from USB HDD.

Note: notebook has fan, however BIOS is by default in "Ultra Quiet mode" so it is very quiet (even more quiet than Cubi).

Hotkeys mapping: to press Fx key (for example F2) in your OS you need to also press Fn key (yes!)

Where is touchpad device?

  • surprise - it is not USB
  • surprise - it is not PS/2
  • it is actually "PCI I2C HID Device" (Huh!)
$ journalctl -b | grep SYNA2BA | sed 's/^.......................................//'

$ lspci | grep 15.1

00:15.1 Serial bus controller: Intel Corporation Alder Lake PCH Serial IO I2C Controller #1 (rev 01)

NOTE: proper support requires also ACPI entry (SYNA2BA6) related entries in NetBSD 11Beta:

TPD0 (SYNA2BA6) at acpi0 not configured
Intel 600 Series PCH-LP I2C 1 (miscellaneous serial bus, revision 0x01) at pci0 dev 21 function 1 not configured
iic0 at ichsmb0: I2C bus

While PCI device is detected by NetBSD.

OS Support

Fedora 43 Beta Workstation (GNOME/Wayland):

  • no issues
  • only in Fedora touchpad gestures work (left-click, right-click etc...)

Qubes R4.2.4

  • seems to work
  • that means that both NPT and IOMMU works - which is good sign

FreeBSD 14.3

  • everything works including GPU

NetBSD 11.0 Beta

  • GPU works, but only in EFI framebuffer mode (i915 driver does not support this GPU)
  • it is general issue with NetBSD:
    • on Zotac that i915drmkms driver crashes kernel (HD Graphics 500)
    • on Cubi it does not support GPU (Iris Xe)
    • same on Lenovo (UHD Graphics)

OpenBSD 7.7

  • important stuff works (NVMe, LAN, GPU)

To test X11 in FreeBSD, I followed https://docs.freebsd.org/en/books/handbook/x11/ with:

pkg update
pkg install xorg
pkg install drm-kmod
sync
kldload i915kms
# next run 'startx' as ordinary user
