After lates update yesterday I get black screen on my integrated display.
I use HP Elitebook 840 G5 for a while and didn't had problems with the system.
It runs Slackware current.
On boot the last line that is visible on the main display is:
Code:
[ 6.487831] fb0: switching to inteldrmfb from EFI VGA
The system boots successfully but without the main display showing any sign of life.
External displays (e.g. over HDMI) working without problems.
I tried with option 'nomodeset' in elilo.conf, and got console login
but can not start graphic mode.
I need some suggestions to fix the issue.
