i915 laptop screen turning Off and back On

what should be its specifications?
I've been testing Asus Vivobook X1407CA with 15.1 for a couple of months. Here is dmesg. It's 16/512GB RAM/SSD.

* Graphics is blured after the first boot, but after a restart or lid down/up, it works:

vgapci0@pci0:0:2:0: class=0x030000 rev=0x03 hdr=0x00 vendor=0x8086 device=0x7dd1 subvendor=0x1043 subdevice=0x1fe3
vendor = 'Intel Corporation'
device = 'Arrow Lake-P [Intel Graphics]'
class = display
subclass = VGA

* XFCE is working. I tested only the basics that come out of the box:

kld_list="i915kms if_rtw89"
lightdm_enable="YES"

* Wifi is working:

rtw890@pci0:1:0:0: class=0x028000 rev=0x00 hdr=0x00 vendor=0x10ec device=0xb851 subvendor=0x105b subdevice=0xe100
vendor = 'Realtek Semiconductor Co., Ltd.'
device = 'RTL8851BE PCIe 802.11ax Wireless Network Controller'
class = network

* Bluetooth is recognized, but it doesn't start out of the box:

ugen1.3: <Realtek Bluetooth Radio> at usbus1
ubt0 on uhub0
ubt0: <Realtek Bluetooth Radio, class 224/1, rev 1.00/0.00, addr 2> on usbus1

# /etc/rc.d/bluetooth start ubt0
/etc/rc.d/bluetooth: ERROR: Unable to setup Bluetooth stack for device ubt0

* The ACPI errors seem to be harmless and might be fixed by a firmware update. Settings in /boot/loader.conf:

debug.acpi.layer="0"
debug.acpi.level="0"


* Touchpad and sound work. Hot keys don't.

I use it as a second notebook, mostly without a desktop. It's 14" with a relatively new chipset, and it's affordable.
 
I don't think it will make any difference.
This problem happens since I remember, so downgrading drivers it's like going back to the version I had a couple of years ago and end in the same result.

It looks like you have Haswell which is mature (no major driver changes any platform in years), but swapping takes less than a minute (don't even have to reboot iirc if unloaded/reloaded, but probably should)
