Please use the fake kms driver instead “dtoverlay=vc4-fkms-v3d”

it its known that the full kms driver isnt compatible with tvservice plus other restrictions

EDIT:
Also with the fake KMS you can rotate the display from /boot/config.txt so I suggest @michmich using it as the preferred method in the wiki

Hi guys

Im new to the forum and this project but I have some small experience with the Pis and having the same issue

I think that its related to the video driver, using ‘sudo raspi-config’ and changing the video driver to one of the GL drivers resulted in a much lower cpu load in my case.

Doesn’t matter if you choose full KMS or fake KMS as long as you dont use the legacy non-GL driver.

It took my 4 CPU from full 100% to idle bellow 35%

Im sure someone else with this problem can confirm this

@ndom91 try the fake KMS if you want to use TV service

It’s what I do

@bradau no sorry, thats not my case

if you dont have any problem with the full kms maybe you will have to search of a tvservice alternative, something that works on any linux desktop and not specific to RPI

Hi @ndom91
tvservice isnt compatible with the KMS driver, you need to use fkms to retain that compativility

Hi Gregory

Im using MagicMirror-FootballLeagues

It works by just adding the league 467

EDIT:

If someone is using it without luck be sure to use an api key and place showUnavailable as true

hi @binderth
the fake-kms was created for keeping omxplayer compatibility but you need to add the “–no-osd” flag to the omxplayer command line

you might want to try it

dont bet on it, but changing line 101 of node_helper.js to

var args = ["--no-osd", "--live", "--video_queue", "4", "--fps", "30",

might do the trick

@schmo90 mmm havent had that problem, everything its working fine

Have you deactivated the screensaver as its shown in the wiki?

Also, are you using a module like MMM-Remote-Control to turn off the screen?

If you see a black screen and the mouse but nothing else you are probably missing “sudo chvt 6 && sudo chvt 7” in your statement after turning hdmi back on. You can test it in ssh after forcing the issue.

Also if you are concatenating commands like Hein-Jan did with “tvservice --preferred && sudo chvt 6 && sudo chvt 7” have in mind that commands after && are only executed if no errors are found. So maybe “tvservice -p” its working correctly but its giving some feedback and things after && aren’t executed.

You could force it by using ; as a separator instead of && so it doesn’t look for an answear

@e3v3a
You can check it in the config.txt

or just do a “tail /boot/config.txt | grep dtoverlay” to check what version is enabled

all the rest of my configuration is the default one after a fresh install from the current version of MM and Raspbian, I havent touched anything from electron
