Re: Using Raspberry PI 3 for remote desktop sessions?

I would not use WoA as it’s very slow on the Pi and really only licensed for the Insiders testers in Windows and not for commercial use. If you are using VNC on the servers you can use the RealVNC viewer on the Pi. Failing that, try rdesktop Remmina or NoMachine Advantage of the latter is that you ...

Re: Cannot reliably set static IP address

OK, so that's the Pi-Hole server back up serving DNS and DHCP, including all of my DHCP address reservations which I have copied back in place from my backup (by copying everything in /etc/dnsmasq.d from the backup to the new setup). Now just need to get samba, kodi and my hi-fi music player sofware...

Re: Cannot reliably set static IP address

Hmmm. It seems Pi-Hole installs dhcpcd if it is not already present on the system. Luckily this has not affected the reliability of my static IP address assignment. It seems if an interface is configured in /etc/network/interfaces, then this "claims" the interface and prevents dhcpcd from messing wi...

Re: Cannot reliably set static IP address

I decided to approach this from a slightly different angle and removed dhcpcd altogether. I then configured the ethernet interface using the "traditional" method using /etc/network/interfaces and all is working reliably. I'm slightly surprised nobody seems to have spotted this apparent bug before :o

Cannot reliably set static IP address

Hi folks. I am having a rather strange problem. The problem is that when I attempt to assign a static IP address to the ethernet interface, sometimes when the Pi boots up it is set correctly, other times it seems to ignore the configuration and instead gets assigned an IP address by the DHCP server ...

The warning in rpi-update actually comes fro mthe firmware repo, https://github.com/Hexxeh/rpi-firmware/blob/master/NOTICE.md. And is currently out-of-date, since it warns about bumping the kernel to 4.19, which is the current kernel version available from the package repos. If the warning is that ...

Re: Two LAN9514 chips on one raspberry.

This won't be a problem, for several reasons. Firstly, the LAN9514 built into the Pi uses a custom USB device ID: I would not expect the firmware to set the MAC address on any 'standard' LAN9514 which may be present. Also, you can set the MAC address to whatever you want in your chosen OS: this is v...

Re: Model 3 A+ Display issues on 55 inch screen

think you are right as without a MMU Memory Management Unit there is no translation to virtual addresses or multiple virtual addresses. Makes no difference if there is no MMU on the GPU - it just means the GPU has to always use physical addresses. And it was you who suggested that. You seem to have...

So which version of chromium as its been like that for a long time but what happens in pixel? What version is needed for that?
If it has always been like that - microstutters and high load - then it won't get any better by going back a version.
