Recently installed NetBSD 9.1 amd64 on USB stick and booting a laptop. x11 is starting, but the screen looks garbled. Even xinit xterm opens xterm but even the prompt doesn't appear correctly. (Looks something like video synchronization going wrong.)
X -configure shows driver as "intel". Tried changing it to "vesa", but that doesn't start. dmesg shows it as i915drmkms0. Would prefer base x11 to work. Let me know if any more information would help. -- Mayuresh
