http://bugzilla.opensuse.org/show_bug.cgi?id=1119621 Bug ID: 1119621 Summary: kernel 4.19 + i915 gives black screen/intermittent display Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Factory Status: NEW Severity: Major Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: masterpatricko@gmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- All 4.19 kernels I have tested (up-to-date Tumbleweed) have given only a flashing/intermittent display after bootloader on my laptop. After GRUB instead of the splash screen, I see the manufacturer image from the UEFI again and then the display spends most of its time off. Sometimes hitting keys (or just randomly, perhaps something to do with screen refresh) brings the display back for a moment and reveals system has actually booted and is operational, just with no display. Problem exists both on tty/console and in X (KDE), starting from the splash screen and continuing till reboot/shutdown. Booting and running kernels from 4.18 series work fine, completely stable, with no changes in configuration. "Recovery mode" also gives a steady tty display. No errors in Xorg.log or dmesg that I can spot.
