Re: Mozilla Thunderbird Versions

A couple of us had a thread on this a couple of months(?) back. The other guy pulled the Debian (or at least a non PiOS version) of Thunderbird and it apparently did not have the slowness problem. Which is why I posted the above. For me at least the PiOS version works OK, after it is up an running. ...

Re: Maximum SD card interface speed

IF I remember correctly the chip for the SD card reader is limited to 40MB/s and the USB chip is limited to 350MB/s(total, Pi4). Jumping from a 100MB/s flash drive to a 300MB/s USB SSD drive(Sandisk) made a HUGE improvement in daily desktop performance.

Re: Raspbian vs Pi OS

I do not think that it really can be based on Raspbian. The major reason for the name change was that the 64 bit version would not have anything Raspbian in it. It also would not make sense to keep the 32bit and 64bit different. Keeping them the same or at least as close as possible(to me) would mea...

Raspbian vs Pi OS

First does an installed Raspbian (32bit) just become Pi OS upon a "standard" update?

After reading the vlog on why the name was changed, I am left to wonder if Raspbian (including the PC version) will continue. Will it become a stand alone OS, will it "morph" in Pi OS, will it just die off?

Audio after 5/28/20 update

This is about the only persistent problem I have had with my Pi4, which I use as a daily driver. The audio stopped working (again) after today's update. It still works if I use VLC and manually change the audio, so it is not a hardware issue. The only hardware oddity is that it is a DVI monitor usin...

Re: Raspberry Pi 4 boot-over-USB with NVMe drive

You probably could have saved yourself a ton of work by just using the usb-boot.zip utility. It pretty much automates all the work you did. The utility is available here on the site. Just do a search for it. RonR does a great job of supporting it.

Alex, thanks for catching that. I had it exactly backwards.

However, it still leaves the question of why the above line(first post) works when hard coded but not when variable coded(as it was originally)?

Cannot get headphones to work after a new monitor.

Re: Raspberry Pi 4 boot-over-USB with NVMe drive

While I would prefer a direct USB boot, I do not understand the impatient foot tapping. As far as I can tell the only speed difference between a hybrid boot and a direct boot would be in booting itself. Considering how short booting is now with the hybrid boot, I doubt you will see much over a ten s...

Re: Raspberry Pi 4 boot-over-USB with NVMe drive

While I would agree that it gets here when it is ready and linked boot is good enough until then, I would disagree that there is no real world advantage.
For starters you will no longer need to have access to the SD card. This is a pretty big deal(PITA) in case design.

Re: New Thunderbird SLOW startup

There was a notice that Thunderbird and the calendar (Lightning?) were separated into two units. So you MAY be seeing a Lightning issue and not a Thunderbird issue. OR it may be a linkage issue between the two.
