Using vc4-kms-v3d lost control on tvservice

@gregoryorciuch I am in the exact same boat as you, and I have not had any luck as of yet. Tried the normal overlay and the “fake” kms, to no avail. To be honest, I’ve just given up for a little bit until people that know what they’re doing have found a solution or the drivers are more stable. I might just do a fresh raspbian install and start anew, to see if that fixes things.
As a side note that doesn’t help much right now, using ‘vcgencmd monitor_on’ (or ‘off’) if you’re able is much, much better than ‘tvservice’.

@pyrosmiley thanks for sharing your experience. Actually because I cannot wakup the screen I put /sbin/reboot in crontab, that is nasty solution but works. But it costs the reboot.
-
@gregoryorciuch Yeah, it’s an ugly solution, but it works! I’d do the same, but my screen is blanking after about 25 minutes at most, and I just can’t justify a full reboot ever half hour.
-
@gregoryorciuch I just remembered – are you using a PIR sensor? It seems like that’s been the source of the problem for a lot of people, and there seems to be a fix. Unfortunately, I am not so that doesn’t impact me and I didn’t remember to mention it.

Hi Gregory
tvservice isnt compatible with the KMS driver, you need to use fkms to retain that compativility -
@cdelaorden I’ve changed the driver from kms to fkms and tvservice commands are now working as is display_rotate=1 in config.txt which is great, the issue I now have is transitions on the screen, compliments changing, news headlines etc are not smooth at all in fact they are quite jittery, any suggestions?
-
@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
