These are the files I downloaded:- total 58M -rw-rw-r-- 1 ian ian 936K Nov 15 18:37 linux-firmware-image-4.12.0_4.12.0-4_i386.deb -rw-rw-r-- 1 ian ian 11M Nov 15 18:37 linux-headers-4.12.0_4.12.0-4_i386.deb -rw-rw-r-- 1 ian ian 46M Nov 15 18:37 linux-image-4.12.0_4.12.0-4_i386.deb To work out which kernel was being installed I did:- dpkg-deb -c linux-image-4.12.0_4.12.0-4_i386.deb Looks like kernel '4.12' is being installed. Booted system with kernel 4.12. The graphics problem did _not_ occur. Did uname -a. Got:- Linux hawking 4.12.0 #4 SMP Fri Nov 10 04:04:10 EST 2017 i686 i686 i686 GNU/Linux IDEA. Given that setting the GRUB environment variable GRUB_GFXPAYLOAD_LINUX to text solves the problem, could this be happening:- * That GRUB is doing something different with its handling of graphics * That the Kernel's graphic driver is taking advantage of some graphics mode setting that GRUB was doing before, but now no longer does?
