Given that the modesetting driver with acceleration is causing a hard
freeze, the most viable alternative to try is the legacy xf86-video-intel
driver. This driver, while older, can sometimes offer better stability on
specific hardware generations.
To use the intel driver, you will need to create or modify your xorg.conf
file (typically located in /etc/X11/) to specify the driver and an
appropriate acceleration method.
Recommended xorg.conf Configuration:
Section "Device"
Identifier "Intel HD Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
Option "TearFree" "true"
EndSection
