Good Day, In the Grub menu, where you are prompted to choose between Graphical install, Install, and so on, you can hit 'e' to edit the Grub entry and prepend the line: set gfxpayload=keep Then hit 'F10' to proceed to the installation. This will conserve the resolution used by this menu, which should be readable, contrary to the following steps. Other values should be possible if you want a better, still readable, resolution: set gfxpayload=1280x1024x32 This may answer at least the first question, hopefully.

Another key is the i7-6700HQ provides HD 530 Intel video. Intel + NVidia usually equates to "Optimus" which makes nouveau.modeset=0 even more pointless, since only the Intel GPU drives the video outputs and may use KMS.

How can I set OS resolution > during install? An alternative suggestion to Curt's is to utilize the kernel's KMS. Curt's suggestion included disabling KMS with either the nomodeset or nouveau.modeset=0 string on the installer's cmdline. Including video=2560x1440 or video=1920x1080 should increase the font sizes without disabling KMS. Including either nomodeset or nouveau.modeset=0 for installation generally means its included in /etc/default/grub and /boot/grub/grub.cfg on the installed system, continuing KMS blockage, and making video performance suffer greatly. Both are intended as troubleshooting workarounds, though traditionally, non-FOSS drivers have required disabling KMS full time. Another key is the i7-6700HQ provides HD 530 Intel video. Intel + NVidia usually equates to "Optimus", which generally means a requirement to follow special instructions for installing either OS or NVidia drivers. These you can find by using Optimus, Prime and Bumblebee as search keywords. Optimus instructions on https://wiki.archlinux.org/index.php/Optimus are reputedly very good, in case any you find for Debian seem inadequate to task. Note too that there are three potentially competent DDX drivers for NVidia, the non-FOSS from NVidia, plus the two from Xorg, nouveau and modesetting. The newer technology modesetting is the upstream default, included in the server package since 4 years ago, but most installations manage to override it by installing all optional DDX drivers via virtual (meta) package, including xserver-xorg-video-nouveau. BTW, upstream's name for DDX drivers takes the form xf86-video-, helpful to know in evaluating search results. Having the nouveau DDX installed blocks the modesetting DDX unless explicitly configured not to via /etc/X11/xorg.conf*. IOW, if you purge xserver-xorg-video-nouveau, or explicitly configure its use, before installing NVidia drivers, you get an opportunity to test whether you even need to add the non-FOSS DDX. -- Evolution as taught in public schools is religion, not science.
