[Dycool]

Your Issue:

I just installed holoISO and when it appears the screen to choose the language, the screen is filled with graphical glitches. I cant even see the languages.

For any one that want to run latest holoiso on intel igpu:

TLDR: DON'T
it's not supported, the hardware support is removed.

Details

• intel drm driver from holoiso repo is removed
  • no iris, i915 driver found in /usr/lib/dri
• intel igpu require some config that already removed
  • env: INTEL_DEBUG=noccs
  • [optional] hybrid laptop requiregamescope parameter: --prefer-vk-device=<your igpu id>
• glitch in desktop mode
  • incompatible linux kernel, cause igpu keeping crash.

it's not meant that holoiso is bad, it just focus on better performance and other AMD variant handheld PC support.

Prepare

tested on ISO Update 5.0.1 (image snapshot20230823.1454)

I gonna use another pc to modify via ssh, so we need network connection.

• wired: just plug cable to laptop
• wireless:
  • press Ctrl+Alt+2
  • login to root
  • type: nmcli dev wifi connect <wifi name> password <wifi password>

find the ip of this laptop

• type: ip addr, and show like:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: enp2s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000
    link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff
3: wlo1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff
    altname wlp0s20f3
    inet 192.168.1.100/24 metric 1024 brd 192.168.1.255 scope global dynamic noprefixroute wlo1
       valid_lft 591sec preferred_lft 591sec
    inet6 fe80::96c3:775a:54e7:5db3/64 scope link noprefixroute
       valid_lft forever preferred_lft forever

we can see our ip is 192.168.1.100.

now, we execute from other pc to access: ssh root@192.168.1.100

Fix Gamemode

do full system update first: pacman -Syu, we need newer holoiso installation to modify.

Revert graphic driver

excute:

pacman -S extra-main/libva-mesa-driver extra-main/mesa-vdpau extra-main/opencl-mesa extra-main/vulkan-intel extra-main/vulkan-radeon multilib-main/lib32-libva-mesa-driver multilib-main/lib32-mesa multilib-main/lib32-mesa-vdpau multilib-main/lib32-vulkan-intel multilib-main/lib32-vulkan-radeon

Add holoiso hardware profile for this laptop

glitch fix

echo export INTEL_DEBUG=noccs >> /usr/lib/holoiso-hwsupport/him_devicequirks/$(cat /sys/devices/virtual/dmi/id/product_name | tr -d '[:space:]').sh

reboot.

[Optional] hybrid gpu support

1. find igpu id: lspci -knn:

......
00:02.0 VGA compatible controller [0300]: Intel Corporation Iris Plus Graphics G1 (Ice Lake) [8086:8a56] (rev 07) (prog-if 00 [VGA controller])
......
03:00.0 Display controller [0380]: Advanced Micro Devices, Inc. [AMD/ATI] Topaz XT [Radeon R7 M260/M265 / M340/M360 / M440/M445 / 530/535 / 620/625 Mobile] [1002:6900] (rev d3)

8086:8a56 is what we need.

2. add to hardware profile to ask gamemode launch on igpu

echo export HOLOISO_GAMESCOPE_ADDITIONAL_OPTIONS=\"--prefer-vk-device=8086:8a56\" >> /usr/lib/holoiso-hwsupport/him_devicequirks/$(cat /sys/devices/virtual/dmi/id/product_name | tr -d '[:space:]').sh

3. reboot

NOTE: run game on discrete gpu: modify game lauch option like this video: https://www.youtube.com/watch?v=9m5RzZ1P1g8

Fix Desktop Mode

even we success to enter gamemode, but still glitch in desktop mode.

Revert linux and firmware

execute:

pacman -S core-main/linux-firmware core-main/linux-firmware-marvell core-main/linux-firmware-whence extra-main/linux-zen extra-main/linux-zen-headers

reboot
