Marhaba – مرحبا
While it requires a certain amount of risk acceptance, due to the fact you install software in Dom0, it might be healthier for you if you calm the blue light on your computer screen.
A great guide has been posted at the QubesOS forum: https://forum.qubes-os.org/t/blue-light-filter-in-xfce-redshift/540/4
Since booting with the latest QubesOS 4.2.3 USB fails with blackened screen, I found this post suggesting booting with an older Qubes 4.1.2 USB, succeeding in installing Qubes OS.
Older Qubes 4.1.2 ISO: https://ftp.qubes-os.org/iso/Qubes-R4.1.2-x86_64.iso
Follow these instructions: https://www.qubes-os.org/doc/installation-guide/
Upgrade the box using these suggestions and change the kernel parameters when booting:
modprobe.blacklist=xen_acpi_processor rd.driver.blacklist=xen_acpi_processor
When upgrading Qubes to 4.2.3, whonix templates fails since the older versions are not maintained, so you might have to delete them and recreate these afterwards.
When finishing the installation and upgrading dom0 for the final time, remember to put the above kernel parameters into the /etc/grub2.cfg. I believe this might be a struggle after every kernel update from here on 🙂
Suspend is not working either. Screen turns dark and nothing happens
Enjoy!
Update: recommend to exchange battery when dealing with an older laptop. Got 2+ hours instead of 30 minutes buying a cheap battery on amazon: Amazon 7xinbox battery
Suspending the laptop is not working. even closing the lid just turns screen black, even with every power management tool I know set on not doing anything. Also, after running for some time, sound turns awful and a reboot is needed, so I tried Ubuntu on this device and everything just works. I absolutely adore QubesOS on my Intel NUC, but this laptop is not a sensible choice for QubesOS. Other hardware is recommended, sadly. The support is non-existing.
