https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=249357 Bug ID: 249357 Summary: graphics/drm-fbsd12.0-kmod: Doesn't work on AMD E-300 (Radeon HD 6310/PALM) laptop Product: Ports & Packages Version: Latest Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: x11@FreeBSD.org Reporter: kumba@gentoo.org Flags: maintainer-feedback?(x11@FreeBSD.org) Assignee: x11@FreeBSD.org I have this old laptop that I've ran FreeBSD on since the 10.x-RELEASE days, and although slow, it generally works for my needs. It's powered by an AMD E-300 APU w/ embedded Radeon HD 6310 GPU (PALM). On a late ~2019 ZFS BE with xorg-server-1.18, running 12.1-RELEASE, everything, including hardware-accelerated compositing, still works. However, after the xorg-server-1.20 update, hardware-accelerated compositing no longer works. It looks like glamor fails to initialize (eglInitialize() fails), so compiz falls back to software rendering, which is unusable. I tried a variety of things, including building xorg-server and mesa from ports, but nothing works, so all I am left with is trying to get newer KMS drivers to work. However, trying drm-fbsd12.0-kmod, when /boot/modules/radeomkms.ko is loaded during boot (via /etc/rc.conf), the screen will get "frosty", is about how I can describe it. It literally looks like it ices over, with this white haze that quickly spreads out from the edges of the LCD inwards to the center. The console text inverts to a medium'ish gray color, like attempting to read a sign in heavy, dense fog, and the machine is completely locked up. The only way to recover is to hard-power the machine off by holding the power button down for ~5 seconds. I have gone as far as building branch drm-v5.0-fbsd12.1 from the kms-drm github repo. Same effect as above. drm-legacy-kmod is the only KMS drivers that will work. I am primarily using the modesetting driver, but have also tried the radeon driver from x11-drivers/xf86-video-ati to no avail. I have also updated the base system to 12.2-BETA1, and that hasn't helped any either. Open to any ideas for testing. I'll likely end up just retiring the machine and moving the drive to something newer, but figured to at least open a bug in case it turns out to be a silly quick fix. -- You are receiving this mail because: You are the assignee for the bug.home | help
