Thanks scruss, The printer was discovered just fine. The installation process seemed to have died just towards the end. To make thing better the printer itself just died after a paper jam. I have had it for a LONG time. A replacement is on the way and due Wednesday. I will play with the new printer ...

I have a Pi 3B+ running Ubuntu Mate 18.04 with all current updates. I attempted to add a network printer (Brother HL5170DN) which is accessible on my LAN. I went through the normal Add a printer drill. I did notice that it seemed VERY SLOW and the system would freeze during the process - no mouse re...

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

Thanks bjtheone

I am seeing similar answers here https://ubuntu-mate.community/t/error-u ... 3b/20001/7

Yes. I am looking at some replies over there.

I am getting this error on 3 of 3 Pi 3B+ computers so I suspect it is a bigger picture issue rather than my systems: root@taylor23:~# apt-get upgrade Reading package lists...

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.

Sound works fine on the 3B+ with Ubuntu Mate 18.04. I just listened to "Locomotive Breath" by Jethro Tull

I do not have a Pi 2. I do have a Zero and a Zero W but they run only Razpbian.

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 ...

taylorkh

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

taylorkh

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.

I just hooked up a new (to me) refurbished Dell 1280 x 1024 monitor to a 3B+. $33 US delivered! As the monitor can pivot so as to present a Portrait layout 1024 x 1280 I decided to give it a try. I found that the monitor configuration under System; Preferences; Hardware; Display said the monitor was...

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...

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...

I have a Pi 3B+ running Ubuntu Mate 18.04 (originally upgraded from 16.04 and now the official image - same issue) which is run headless as a Bit Torrent client. Briefly it is configured thus: On-board NIC manually set to an IP address on my LAN, firewalled to prevent Internet traffic - only ssh and...

I am setting up a Pi 3B+ with Ubuntu Mate 18.04 with the goal of remote access using x0vncserver (from the vnc4server package) to allow connecting to a Mate desktop on the Pi rather than a virtual desktop. I have done the latter but it is not meeting my needs for this project. So far I have: install...

Thanks W. H. Heydt, The last VGA monitor I purchased was in 2011. It was an Acer 19" wide screen. It is still working fine on the wife's PC. The monitor on my test bench is a Samsung 17" which I purchased in 2007. Still works great. My other VGA monitor is a 15" Star Tech which I purchased in 2006. ...

I have several Pi 3B and 3B+ computers. I have one monitor with a DVI connector and a HDMI to DVI cable does the job. I have also used HDMI to VGA converters to connect to a couple of older VGA monitors. All work fine using Ubuntu and Raspbian. Yesterday I came across the CentOS 7 with KDE image. I ...

Thanks tpyo kingg,

That explains it exactly.

The Raspbian documentation https://www.raspberrypi.org/documentation/linux/usage/users.md explains how to add a user, make the user a sudoer and optionally to grant them passwordless sudo access. This is consistent with other Linux distros with which I am familiar. My question is... How/why does the...

taylorkh

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.

Ken

The trick is to start with the raspbian-lite image - with NO gui. I have tried installing Mate over top of Raspbian with the LXDE desktop but there does not seem to be any way to select the desired environment. I believe this has to do with the window manager and I am not familiar with how to do tha...

And i it even runs on a Pi Zero-W. Not very fast but it does run

I just popped the card from the 3B+ into the Zero-W and it booted right up.

I am running Ubuntu Mate 18.04 on a Pi 3b and 4 Pi 3B+ computers. I started with UM 16.04 on the 3B and by a combination of trickery enabled the image to boot a 3B+ and performed a do-release-upgrade to get to 18.04. This has been working well except that man pages are broken on 18.04 :( I have trie...

Thanks Douglas11, This all sounded nice in theory but the Pi Zero-W is proving somewhat troublesome as I described in this thread on the Troubleshooting forum https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=233247 At the moment I am experimenting with the Zero-W and WiFI. I had a heck of a t...
