A workaround seems to be disabling 'kernel mode setting'. (https://wiki.ubuntu.com/X/KernelModeSetting)

Since I am a clueless user ;-), I am not sure how to do this. I tried these two things:

1. execute this command (as root):

echo options i915 modeset=0 > /etc/modprobe.d/i915-kms.conf

2. edit /etc/default/grub; change the line starting with GRUB_CMDLINE_LINUX_DEFAULT to

GRUB_CMDLINE_LINUX_DEFAULT="splash quiet nomodeset"

and then: update-grub
