I have a NetBSD 8.0 installation on a USB stick, working fine on an asus laptop.
Now I have another lenovo laptop[1] that boots fine using the same stick but for HDMI not showing any output. $ uname -a NetBSD asusnetbsd 8.0 NetBSD 8.0 (GENERIC) #0: Tue Jul 17 14:59:51 UTC 2018 mkre...@mkrepro.netbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC amd64 x86_64 AMD 686-class NetBSD Please the following dmesg message, also let me know if I should grep for more: $ dmesg | grep -i hdmi hdafg0: HDMI00 2ch: Digital Out [Jack] HDMI cable is connected right from boot time and it shows nothing during boot. I don't think it's an X11 matter. But just in case it matters I am using native X11 and xrandr shows: $ xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 1366 x 768, current 1368 x 768, maximum 1368 x 768 default connected 1368x768+0+0 0mm x 0mm 1366x768 0.00 1368x768 0.00* Would appreciate help to get this work.
