So my queries before I proceed: Is the installer ISO, "firmware-10.9.0-amd64-netinst.iso", from the link: https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/current/amd64/iso-cd/firmware-10.9.0-amd64-netinst.iso, sufficient for the purpose?
Are the steps (i summarise your points): a default installation will include xserver-xorg-video-nouveau, To use the modesetting DIX instead of the nouveau DDX on a fresh installation, it may be sufficient to do nothing specifically regarding X drivers ... ... sufficient to purge xserver-xorg-video-nouveau and restart X to engage the modesetting DIX. ... Query: you meant apt-get purge xserver-xorg-video-nouveau ? Could you please help with the exact line? A note: it has repeatedly been checked that default nouveau never worked with the nvidia chipset of my laptop. Any last minute advise please? Best, Rajib
