Hello FreeBSD community! I am fairly new to the FreeBSD project. By chance is there a nightly branch targeting graphics development for the FreeBSD ecosystem for DRM and my guess is EFIFB.
I’ve come across some community development resources. I am mainly looking to contribute where I can DRM drivers https://www.freebsd.org/status/report-2025-04-2025-06/drm-drivers/ Robert ________________________________ From: [email protected] <[email protected]> on behalf of Charlie Li <[email protected]> Sent: Saturday, January 3, 2026 1:01 AM To: Ben Hutton <[email protected]>; [email protected] <[email protected]> Subject: Re: XFCE unusably slow when only on laptop screen Ben Hutton wrote: > Is anyone able to help? > > On further investigation it appears the latest drm updates do not work > well with a hybrid mode laptop.

Assuming you are using X, will need to compare Xorg.logs between external monitor connected or not. Note that mesa is the userspace side for Intel, x11/nvidia-driver is the userspace side for Nvidia. For Nvidia, x11/nvidia-driver and x11/nvidia-kmod (kernel side) have to match. Additionally, you may want to check if you have or need the appropriate graphics/nvidia-drm-kmod. > > >> On 30 Dec 2025, at 10:35 pm, Ben Hutton <[email protected]> wrote: >> >> Hi, >> >> I have an odd problem since doing a pkg upgrade earlier today.

My W550s, a few generations back, only does headless. -- Charlie Li ...nope, still don't have an exit line.
