https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D253159 Bug ID: 253159 Summary: Display issue on HP Laptop: Can't boot with any FreeBSD Product: Base System Version: Unspecified Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: pioruns2020@gmx.com Hi all, I've tried 3 FreeBSD based distributions on my laptop. Unfortunately, it doesn't even boot on it, causing CPU to hang completely (I can tell be slow= ly blinking Caps which indicates CPU freeze), requiring physical power off and power on again. I've tried all available safe mode and other options. Sometimes, it doesn't lock up, but it never goes further than initial boot menu, after that it's only text console with garbled screen where nothing c= an be read, it's just all messed up, instead of text it's all messed up pixels= in inclined bunches where text lines supposed to be. I think this has something to go with display screen resolution. I have 1366x768 LCD. I remember once wanted to have higher resolution in Linux GRUB and result was the same, garbled inclined lines and nothing readable. Hardware is HP Probook, AMD A8-4500M APU with 8GB RAM. GPU is called Radeon= HD 7640G (I think it's embedded in this CPU). On Linux, everything is working = out of the box. Solution: add some safe mode with fixed resolution of 640x480 or something,= or fix underlying problem with display resolution. Distros tested: NomadBSD 1.4-RC1 amd64 (based on FreeBSD 12.2) GhostBSD 21.01.20 amd64 (based on development branch of FreeBSD) MidnightBSD 2.0.3 amd64 (based on FreeBSD 11) HW details: Machine: Type: Laptop System: Hewlett-Packard product: HP ProBook 4545s v: A1019D1103 serial: <superuser required>=20 Mobo: Hewlett-Packard model: 17EA v: KBC Version 54.20 serial: <superuser required> UEFI: Hewlett-Packard=20 v: 68CPD Ver.
