Title:
Black Screen on 18.04 + Intel Graphics with Kernel > 4.15.0-47
Status in linux package in Ubuntu:
Fix Released
Bug description:
Hi,
we've been running 18.04 (w/ Xubuntu) + 4.15.0-47 kernel for a while
now (on Minix Z83-4 devices w/ Intel X5-Z8350 CPUs), which is working
fine.
After upgrading the kernel to a newer version (> 4.15.0-47), HDMI
output is not available anymore, i915 reports an invalid EDID version
via dmesg I dropped the full dmesg output on Pastebin:
https://pastebin.com/jXTqAzkQ
As a start I'm blaming the Linux kernel since booting 4.15.0-47 kernel
works just fine.
Known faulty kernel versions are:
- 4.15.0-58-generic
- 4.15.0-59-generic
- 5.0.0-25-generic
Not sure how to best collect logs and system information for you since
I'm not used to debugging black screens. However, SSH access is
possible. I am happy to provide more information, if needed. We can
also install and test experimental kernel versions.
Note: This happens then attached via a standard HDMI cable as well as with a
HDMI-DVI cable on different monitor setups.
