Re: Buster bug report thread

I fixed it by modding /boot/config.txt overscan_left=-48 overscan_right=-48 overscan_top=-48 overscan_bottom=-48 hdmi_drive=2 With hdmi_drive=2 to enable HDMI audio. Although my primary audio is pulseaudio over the network (less resource intensive on the client machine(s)). Oddly setting those all t...

Re: [solved] RPi 4 unable to connect to WiFi

I've had issues where turning on an LCD display near the TV or LED lights would interfere with ATSC signal reception (OTA TV). On an older HDTV (circa 2006). You might fool around with some tin foil to shield things. Assuming the wifi is not near the TV/Display. I originally got my mom to switch to ...

Re: How do I get multiple backgrounds back?

I tend towards more wm/de agnostic ways. And otherwise use xsetbg to set the background image. Or I use xsetroot to set the background to a solid color. $ xsetbg -brighten 122 -gamma 1.8 image.png $ xsetroot -solid rgb:00/22/00 $ xsetroot -solid Blue4 Although I'm not sure what you're referencing.

Re: Buster bug report thread

On a RPi 4b 4GB, after update, when I reboot with the monitor plugged in, there's overscan (underscan?). Resulting in a non-native resolution with a large black border where pixels should be. IF I boot with the screen unplugged from HDMI, this is NOT an issue. But if I boot with the screen plugged i...

Re: Raspi 4 file server disappointing transfer speed, degradation and segfaults

Probably of no use to you, but I just setup a ZFS two usb disk mirror shared over NFS and haven't had any issues. But no encryption, unless ZFS defaults to encrypted. It works rather nicely and transfer speed is good enough over the 10/100 switch. Only took about 12 hours to get 400GB-ish of data on...

Re: Upgrade from pi 2B rev 1.1 to pi 4B(4GB)

I was NOT able to use the image I made for the RPI 3B+ on my new RPi 4B 4GB. I had to do a NOOBS install. Sadly lacking in linux instructions. But you literally unzip the image into the fat filesystem the SD cards ship with. Which gives you two options to install on the card at boot time: Raspbian o...

Re: jackdbus crashing regularly in raspbian after update.

Still stable with the arbitrator (snd-aloop / alsaloop), even with multiple sources hitting the RPi at the same time. On the plus side I can push the RPi 3B+ to 24 bit and 192kHz. Which adjusts the alsaloop a bit. One quirk is having to stop / start pulseaudio (client side) to another user if I swit...

Re: Why do I have an dynamic (DHCP) IP address if setting a static IP address on Raspian Lite Stretch?

It's because dhcpcd is running at boot. My post boot steps involve stopping it and wpa_supplicant, since I'm only using ethernet. Of course avahi-daemon also sets up a network at boot (if you don't set one), which is another thing I stop (although certain things start it up again) and adjust with ip...

Re: How to set display brightness on the Raspberry Pi?

you can adjust the backlight as such # echo 32 > /sys/class/backlight/rpi_backlight/brightness which takes values 0-255 as indicated with max_brightness in the same path. For my 3B+ with the 7" screen. On my x86 systems you can adjust X with xrandr (when NOT nVidia). $ xrandr --output HDMI_SOMETHING...

With the current setup, it is consistently dying at 1 hour of use. Almost exactly 1 hour. Plus 2-ish minutes but that's probably how long it takes me to reload the client to start using audio again.

Re: One of my Pi:s cannot connect to internet, needs 192.168.x.x, gets 169.254.x.x.

Seems like avahi-daemon is stomping on your toes. (steps on mine too). It sets up a default ip/route when it thinks it didn't find one. Which overrides the route you "want" to take. $ sudo ip addr del 169.254.156.66/16 dev eth0 $ sudo ip route add default via 192.168.1.1 dev eth0 Is a regular part o...

It failed of course. But it took an hour-ish, and 45-ish on subsequent fails. So it's "better".
