HDMI config problems after Raspberry Pi TW 4.15.13 -> 4.16.6 update

Mon Mar 18, 2019 9:31 am

I just updated Tumbleweed from 4.15.3 -> 4.16.6 on my Raspberry Pi 3B (not +), and I found that the HDMI settings are incorrect: 3-4 characters are lost off the left side of the screen, and several lines are lost at the beginning. (Was working fine on 4.15.3.) Looking at the /boot/efi/config.txt files (which was changed between releases), I see that there are driver changes but no obvious changes in HDMI parameters that I could tinker with.

This seems to be an issue only when booting in multi-user mode. Starting XFCE, the windows seem to come up just fine with no missing parts on the menu bars or icons.

I copied the following config.txt settings from Raspbian's config.txt boot file and inserted them right after the "dtoverlay=rpi3-hdmi" setting in TW 4.16.6:
Code:

Code: Select all

hdmi_force_hotplug=1
config_hdmi_boost=4
overscan_left=24
overscan_right=24
overscan_top=16
overscan_bottom=16
disable_overscan=0
but the HDMI behavior in multi-user mode didn't change (not surprising, but I had hoped that fixing it would be just that simple).

I referred to the site referenced in the config.txt header, "https://www.raspberrypi.org/documentati ... /README.md" and the video settings it cites, and so I also tried "hdmi_safe=1". While that resulted in REALLY BIG letters during initial boot, the login screen was similarly cut off on the left.

Any suggestions where else I might look or settings I should change? It appears to be an issue with rpi3-hdmi, but I can't find documentation on how to change its settings.

This is only a minor nuisance, but as I frequently run in multi-user mode, I'd like to fix it for myself. In general, the graphical support in XFCE seems faster and the system more responsive. Whoever's doing this work: Nice job!

This forum is basically dead. If you will find ANY help, then via the ARM mailing list of opensuse or in the "Install/Boot/Login" forum for opensuse. Just mention ARM/raspi and malcolm lewis might be your man, if he sees any chance to help...
Kind regards
