Re: chromium-browser *used* to work on a pi0w, not now

I've found the culprit really is rpi-chromium-mods, not chromium itself. The fix to get a working chromium v65 back is: Downgrade rpi-chromium-mods package to the last compatible version, and then put a hold on it to stop it upgrading again: sudo apt-get install rpi-chromium-mods=20180302 sudo apt-m...

"raspberry pi desktop for pc" is packaged from Debian linux, so should work where Debian does.

Re: chromium-browser *used* to work on a pi0w, not now

IIRC the changes mentioned in my linked thread above the ( to make chromium work on pi1/zero) were eventually put into the raspbian repos.

- maybe not applied for later versions of chromium....

Install earlier compatible version of chromium:

Code: Select all

 sudo apt-get install chromium-browser=60

Re: USB Boot For Gateway 4530GZ Not Working

Often USB drives will show up in the bios as HDDs, not as usb/removable.

With the usb plugged in, go into the bios,
and change the HDD priorities to show the lexar first.

The built-in persistence is brilliant; I don't know why more distros can't/won't do this, but it's fantastic.
A quick and simple way to have persistence on many distros is to use multibootusb. I use that for Mint & Ubuntu.

Re: Static IPs for 45 Raspberry Pis!

A more sensible approach might be to just have unique hostnames and access via those.

Raspbian has mDNS, so will respond to hostname.local (raspberrypi.local by default)

Writes are similar at around 20 meg/sec:

but oddly the RAMdisk doesn't max out the interface on samba writes;
I expected 35 meg/sec but only got 20meg/sec, same as USB HDD:

Re: samba allow write all users

You need far less than that:

Code: Select all

[Home]
path = /home/pi
read only = no
guest ok = yes
Then also

Code: Select all

sudo chmod a+w /home/pi 
Insecure, anyone can read/write - but gets the job done.
