I have just bought a new computer (with an Intel Core i9 10850K CPU, so a Intel UHD Graphics 630 CPGPU).
It is shown here:
$ lspci -v
00:02.0 VGA compatible controller: Intel Corporation Device 9bc5 (rev 05) (prog-if 00 [VGA controller])
DeviceName: Onboard - Video
Subsystem: ASUSTeK Computer Inc. Device 8694
Flags: bus master, fast devsel, latency 0, IRQ 144
Memory at 6000000000 (64-bit, non-prefetchable) [size=16M]
Memory at 4000000000 (64-bit, prefetchable) [size=256M]
I/O ports at 3000 [size=64]
Expansion ROM at 000c0000 [virtual] [disabled] [size=128K]
Capabilities: <access denied>
Kernel driver in use: i915
Kernel modules: i915
I am trying to setup an ArchLinux on it, but when it comes to starting SDDM, I get a black screen with a cursor at startup.
I have followed the Xorg wikipage by installing xorg-server and xf86-video-intel.
Additionally, as specified in the Intel graphics wikipage, I have created /etc/X11/xorg.conf.d/20-intel.conf with:
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
EndSection
After digging into my logs I get the following ones:
$ systemctl status sddm

I have also tried a sddm-greeter:
[23:38:20.242] (II) GREETER: High-DPI autoscaling not Enabled
[23:38:20.244] (WW) GREETER: could not connect to display
[23:38:20.244] (II) GREETER: Could not load the Qt platform plugin "xcb" in "" even though it was found.
[23:38:20.244] (EE) GREETER: This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: wayland-org.kde.kwin.qpa, eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.
While my Xorg.0.log gives me a classical:
(EE) Failed to open authorization file "/var/run/sddm/{1d4eff37-b951-4f1a-aaed-3371dfcdcb66}": No such file or directory
Which usually indicates that my video driver is not correctly configured, while I am able to perform a startx.
Here are the relevant installed packages:
local/libdrm 2.4.102-1
local/linux 5.8.14.arch1-1
local/sddm 0.18.1-3
local/sddm-kcm 5.19.5-1 (plasma)
local/xf86-video-intel 1:2.99.917+908+g7181c5a4-1 (xorg-drivers)
local/xorg-server 1.20.9-2 (xorg)
Is there anything I have neglected? Thanks by advance.
