Re: Raspbian Mate anyone?

I have installed the official Ubuntu Mate 18.04 image on several Pi 3B and 3B+ (rather than upgrade.) man pages work fine.

Re: No sound on Pi3b+

The audio hardware on the Pi 3B+ is shown as "Analog mono output" so no, there is not stereo. I do have a Bluetooth headphone receiver gizmo which does produce stereo sound from the Pi.

Re: No sound on Pi3b+

Sound works fine on the 3B+ with Ubuntu Mate 18.04. I just listened to "Locomotive Breath" by Jethro Tull :D I do not have a Pi 2. I do have a Zero and a Zero W but they run only Razpbian.

Re: Custom launcher on Panel or Menu?

Thanks BullittBourbon, I have sort of thrown in the towel on Raspbian. I had built a nice gateway, router, firewall, VPN sharing box from a Pi Zero. I had migrated down from an Intel box with CentOS 7 to a Pi 3B with Ubuntu to the Zero. It carried the load, however, Raspbian kept changing the names ...

I went back to 16.04. It does not provide for on-the-fly changing of display settings either.

Re: Rotate monitor image on 3B+ Ubuntu Mate 18.04?

Thanks aBUGSworstnightmare,

I was just trying to change it on the fly. I can do that with nVidia and Intel graphics drivers. I had never tried on a Pi. I will give your approach a try although I will probably leave the monitor in landscape most of the time.

Rotate monitor image on 3B+ Ubuntu Mate 18.04?

mate-panel --replace does not seem to be a viable answer. I ran it for a couple of hours and all appeared OK. Until I touched a window on the remote desktop. Then all sorts of mess let loose. Flashing panels, windows etc. I had to ssh to the machine and kill the vncserver session and start over. I a...

Re: mate-panel is eating my Pi (at least the memory and swap)

Thanks rpdom, There is a mate-panel --reset. However, that removed all the customization I had done to the top panel :( I see there is also a --replace option. That does not seem to disrupt any settings. I guess I might put that in my script instead of killall. I wish the Pi had 4 GB :mrgreen: Ken p...

paswordless sudo in Raspbian

This is consistent with other Linux distros with which I am familiar. My question is... How/why does the...

Re: Raspbian Mate anyone?

I will give the instructions on the linked page a try. Weezy is rather out of date. The current version of Raspbian, based on Stretch, uses systemd to control startup. startx no longer works. The command is systemctl isolate graphical.target.
