https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D220043 Bug ID: 220043 Summary: Waveshare 7'' USB touchscreen display not fully supported Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: usb Assignee: freebsd-usb@FreeBSD.org Reporter: bcr@FreeBSD.org Created attachment 183528 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D183528&action= =3Dedit Collection of usbconfig dumps and info I bought the following device [1] (without the bicolor case) for my raspber= ry pi 0.=20 The device can be used on any computer with an HDMI interface and acts as a small secondary monitor. I wanted to use it on my RPI-0, but I encountered = the following problems: - When I boot the system, it tries to sync to the proper resolution, result= ing in horizontal lines being printed. No text is visible. This continues even after the RPI-0 has finished booting. When I switch to another monitor and back, the Waveshare display displays the login screen as usual. However, the bottom part is cut off. When rebooting with the Waveshare connected, it tri= es to detect the resolution again without success (horizontal lines again). It seems to not get the proper screen resolution and even when I hook up another monitor, switch back to the waveshare, and login, it is missing par= ts of the right side of the screen and the bottom parts (for example, I can't = see the end of a man page).=20 The manufacturer provides these instructions for Raspbian (config.txt): max_usb_current=3D1 hdmi_group=3D2 hdmi_mode=3D1 hdmi_mode=3D87 hdmi_cvt 1024 600 60 6 0 0 0 I tried setting the 1024x600 resolution in rc.conf for vt, but it had no effect. I saw the 5'' model from the same manufacturer work correctly with FreeBSD,= so I assume the 7'' model needs just a few adjustments. The output of usbconfi= g is attached.=20 Let me know if you need more information. I can test patches and provide feedback.
