FreeBSD 12.2 intel graphics bug
I updated my laptop to FreeBSD 12.2 and could no longer start X. My laptop is a Lenovo Thinkpad T470 with intel graphics.
The quick and dirty workaround was to configure X to use the vesa driver rather than the intel graphics driver.
# /usr/local/etc/X11/xorg.conf.d/driver-intel.conf Section "Device" Identifier "Card0" Driver "vesa" # Driver "intel" # Option "DRI" "3" EndSection
After this change I could start X, but the vesa driver is slow.
I found the fix in a tweet.
The problematic package is drm-kmod. The fix is to rebuild it from the ports tree.
Instructions copied from tweet:
# svnlite release # portsnap auto # make -C /usr/ports/graphics/drm-fbsd12.0-kmod build deinstall install clean
Switch the X config to use the intel driver again, and reboot, and X will be working again with the intel driver.
Here’s the contents of my /usr/local/etc/svnup.conf:
