1: I installed the latest version of Archlabs on a new AMD Ryzen 5 - 8gb ram machine, and Nvidia+Radeon graphic cards, it turns out that until I run the “startx” command, I have a lower resolution than when i3 is charging. How to remedy this? (I use the Nvidia card for now).
2: And for the management of the ram, when I run htop, I can see that only 7gb are taken into account. Where is the missing gb?
Perhaps it is reserved for something else? thx in advance.
Sounds like kernel mode setting is not enabled, see this guide for NVIDIA cards.
Early KMS start is also a possibility: https://wiki.archlinux.org/index.php/Kernel_mode_setting#Early_KMS_start

Looks like your firmware (“BIOS”) may be reserving some memory, the kernel will also take a small amount (but not a gigabyte).
You could trawl through
dmesg, that should record what the kernel is doing with memory allocation.
Have you tried adding
nvidia-drm.modeset=1 as a kernel parameter (as suggested in my link)?
The resolution can be forced: https://wiki.archlinux.org/index.php/Kernel_mode_setting#Forcing_modes_and_EDID
So do I have to run sysctl -p nvidia-drm.modset=1 ?
I’m a bit scared touching those kernel things…
Or maybe should I set this GRUB_GFXMODE=1920x1080 in /etc/default/grub ?
No, you need to add a kernel command line parameter using the bootloader.
For GRUB, add the parameter between the quotation marks on the GRUB_CMDLINE_LINUX line in /etc/default/grub then save the file and update the configuration with
grub-mkconfig -o /boot/grub/grub.cfg
This method was linked from the ArchWiki page, @Alad has made it into a tv-tropes style link-fest

What is the output of

Ah, I’ve just read the (rather prominent) note on the ArchWIki page for kernel mode setting:
So it looks like you need to use nouveau to get a high resolution console screen.
To bad, anyway thanks again, I 'll go with that un-Aesthetic mode hahaha
Sorry cause I’m not a native english man and you took time to read thoses articles for me, so I’m greatfull. I will be happy to help if one day you need.
I finaly got rid of the nvidia-390xx driver, I’m not a gamer and nouveau does the job.
