I'm guessing you mean slow video performance. > dmesg | grep -i firmware > [ 2.072553] i915 0000:00:02.0: firmware: failed to load > i915/kbl_dmc_ver1_04.bin (-2) > [ 2.072556] firmware_class: See https://wiki.debian.org/Firmware for > information about missing firmware > [ 2.072558] i915 0000:00:02.0: Direct firmware load for > i915/kbl_dmc_ver1_04.bin failed with error -2 > [ 2.072559] i915 0000:00:02.0: [drm] Failed to load DMC firmware > i915/kbl_dmc_ver1_04.bin.

And if yes, how do go about getting them? In general, you can search for the specific filenames on http://packages.debian.org/ to see which packages you need, and then install those packages. You'll either need to download the packages manually (not recommended), or add contrib and non-free to your sources.list. Doing the latter allows you to receive upgrades to these packages in the future, so it's the recommended way. See <https://wiki.debian.org/SourcesList#Example_sources.list> for specific syntax. After editing sources.list, "apt update" and then "apt install pkgnames". Here are two of them: unicorn:~$ dpkg -S i915/kbl_dmc_ver1_04.bin firmware-misc-nonfree: /lib/firmware/i915/kbl_dmc_ver1_04.bin unicorn:~$ dpkg -S rtl_nic/rtl8153a-3.fw firmware-realtek: /lib/firmware/rtl_nic/rtl8153a-3.fw You can use packages.debian.org, or apt-file, to get the names of the rest.
