Re: Intel 13700k iGPU not recognised

Hi Felix and Kaelyn

Thank you for the prompt and detailed reply! 

I get mesa being too old for my CPU, and I also tried installing a newer mesa version (that I found packaged in the wild, could also be that it wasn't perfectly packaged but it built fine). 

What confuses me more is the output of lspci, I just booted a new Guix installation  iso and dropped into a terminal, and this is the output from lspci:

00:00.0 Host bridge: Intel Corporation Device a703 (rev 01)
00:02.0 VGA compatible controller: Intel Corporation Device a780 (rev 04)
00:08.0 System peripheral: Intel Corporation Device a74f (rev 01)
00:0a.0 Signal processing controller: Intel Corporation Device a77d (rev 01)
00:14.0 USB controller: Intel Corporation Device 7ae0 (rev 11)
00:14.2 RAM memory: Intel Corporation Device 7aa7 (rev 11)
00:16.0 Communication controller: Intel Corporation Device 7ae8 (rev 11)
00:17.0 SATA controller: Intel Corporation Device 7ae2 (rev 11)
00:1c.0 PCI bridge: Intel Corporation Device 7ab8 (rev 11)

00:1c.3 PCI bridge: Intel Corporation Device 7abb (rev 11)
00:1f.0 ISA bridge: Intel Corporation Device 7a86 (rev 11)
00:1f.3 Audio device: Intel Corporation Device 7ad0 (rev 11)

03:00.0 SATA controller: ASMedia Technology Inc. ASM1062 Serial ATA Controller (rev 02)

Just for reference, the kernel version: (but I had the same problem with the 6.2.7 kernel)
Linux gnu 6.0.10-gnu #1 SMP PREEMPT_DYNAMIC 1 x86_64 GNU/Linux

Before mesa, shouldn't the kernel take care of these devices? When on a different distro I get:

00:00.0 Host bridge: Intel Corporation Device a703 (rev 01)
00:02.0 VGA compatible controller: Intel Corporation Raptor Lake-S UHD Graphics (rev 04)
00:08.0 System peripheral: Intel Corporation Device a74f (rev 01)
00:0a.0 Signal processing controller: Intel Corporation Device a77d (rev 01)
00:14.0 USB controller: Intel Corporation Alder Lake-S PCH USB 3.2 Gen 2x2 XHCI Controller (rev 11)
00:14.2 RAM memory: Intel Corporation Alder Lake-S PCH Shared SRAM (rev 11)
00:16.0 Communication controller: Intel Corporation Alder Lake-S PCH HECI Controller #1 (rev 11)
00:17.0 SATA controller: Intel Corporation Alder Lake-S PCH SATA Controller [AHCI Mode] (rev 11)
00:1c.0 PCI bridge: Intel Corporation Alder Lake-S PCH PCI Express Root Port #1 (rev 11)
00:1c.1 PCI bridge: Intel Corporation Alder Lake-S PCH PCI Express Root Port #2 (rev 11)
00:1c.3 PCI bridge: Intel Corporation Device 7abb (rev 11)
00:1f.0 ISA bridge: Intel Corporation Device 7a86 (rev 11)
00:1f.3 Audio device: Intel Corporation Alder Lake-S HD Audio Controller (rev 11)
00:1f.4 SMBus: Intel Corporation Alder Lake-S PCH SMBus Controller (rev 11)
00:1f.5 Serial bus controller: Intel Corporation Alder Lake-S PCH SPI Controller (rev 11)
02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05)
03:00.0 SATA controller: ASMedia Technology Inc. ASM1062 Serial ATA Controller (rev 02)

So might be that the problem is elsewhere, besides mesa?

Thank you and best regards,
Erik
