Going by the PCI ID you posted earlier (from lspci output), and looking that ID up in the LKDDB, it appears that the kernel module for the graphics component of this chip is i915.ko: https://cateee.net/lkddb/web-lkddb/DRM_I915.html On my system (tracking current testing), I have: $ find /lib/modules/`uname -r` -name i915.ko /lib/modules/3.16.0-4-amd64/kernel/drivers/gpu/drm/i915/i915.ko So: yes, Debian has a driver for this integrated graphics controller. Did you try the command based on 'lspci -k' which I gave earlier? I think we've tracked down the driver you probably need, but I'm fairly sure that command would have been an easier way of finding out what driver(s) you're actually currently using. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
