Graphical Environments & Desktops • Graphics issues after reinstalling Debian with no DE

> Laptop: LG Gram 14" - Intel Alder Lake i7-1260P - uses integrated graphics

Yesterday I've reinstalled Debian only with 'standard system utilities' selected in taskel (since I want to configure everything myself to learn about the system more). I've followed the Debian's Linux Installation Guide
My steps after first reboot: installing `xorg`, `awesomewm`, copying default Xorg config to `/etc/X11/xorg.conf` setting up `.xinitrc`. Starting X session is fine, the window manager by itself works fine but there are critical graphical issues, for example:

• Using the Kitty terminal (it's a GPU based terminal) I get major lag/freezes/tearing, characters pop-in/cease to exist, etc. In comparison, xterm is working fine.
• Watching videos in Firefox is like ~5 fps.
• While trying to draw in Krita the canvas freezes.

Things I've tried:

• Checking if firmware is installed: updated `sources.list` file, ran `# apt install firmware-linux* intel-microcode` but everything was already up to date (QUESTION: should I try `apt install firmware-intel*` or is it unnecessary?)
• Updated the kernel: to `6.10.11+bpo-amd64` but no difference.
• Checked Kernel Modesetting: for some reason I had no `/etc/modprobe.d/i915-kms.conf` and I made one with `options i915 modeset=1` settings, no difference (QUESTION: did something go wrong with the installation of the drivers if I didn't have such file? Because DebianWiki says KMS is enabled by default)

Other info:
Debian 12.6 with KDE used to work just fine on my laptop. Also currently I don't have any sound but it's probably unrelated to this issue.
