My Desktop has Firefox Web Browser 47.0 and Firefox ESR 52.4. No obvious difference in how they work. All Google will tell me is, ¨Firefox ESR is intended for groups who deploy and maintain the desktop environment in large organizations such as universities and other schools, county or city governments and businesses.¨

Both handle my email just fine. (With Midori, I get the ¨slow¨ version of my email.) Any reason I should use one or the other?

Something else I´ve been meaning to ask. My kernel 4.18 download came with the .dtb files, cyrus.eth.dtb, cyrus_p5020.dtb, and cyrus_p5020_eth_poweroff.dtb. I´m no longer sure whether I´m using one of those, or using the one I got for MATE 16.04. How does one decide?

I would recommend you to use the device tree blob cyrus_p5020_eth_poweroff.dtb. It has poweroff support. ;-) That means you can power off your X5000 with Linux.

Whee! The first one worked!


Except when I try to turn
Code: Select all
setenv bootargs root=/dev/sdb2
fatload usb 0:1 1000000 uImage-4.18
fatload usb 0:1 2000000 cyrus.dtb
bootm 1000000 - 2000000
and run it, it fails to read the kernel. And thereafter it also fails to read it from usb 1:1 as well as from usb 0:1 or 1:1 with root set to sdc2!

Very frustrating. I finally had to reboot and enter the lines one by one to get Remix up.

You tried to boot uImage-14.8 but in my point of view you wanted to boot uImage-4.18.

Egads! I really hate dementia. :cry:

I have just had a new scare. I ran lsblk just for the heck of it, but it is very different from Saturday! What was sda on Saturday is now sdd. What was sdc is now sdb. There is no sda, no sdc. What the heck is going on? The UBUNTU icon is missing from Desktop, too.

Please choose the keyboard layout English (US).

Menu System - Preferences - Hardware - Keyboard. After that select the tab Layouts and then the button Add. Choose United States and then English (US). Afterwards click on the button Add and move up English (US) to the first place.

I should have edited my reply. I fixed my keyboard right away. But I chose a slightly wrong keyboard and I am not immediately able to fix it. My System > Preference > Hardware has changed and is at the moment different from yours (see below). Mine no longer has Keyboards, Keyboard Shortcuts, or Mouse. I also lack Control Center under Preferences. Meanwhile, Right-click > Change Desktop Background continues to do nothing.

One more worry. There is at least one program that I used a lot in MATE 16.04 (Gnucash) that is not available in Remix. Have I totally lost 16.04? My Uboot Ubuntu script did not include a ¨setenv bootargs" command and I have no idea how and where it found the MATE .img. Would it still be around somewhere?

Something is wrong with your Remix installation. Could you please copy the img to the partition again?

My attempts to download it have failed so far. This is likely the reason:

I am astonished, and so far haven´t been able to come up with a solution. Presumably ¨This computer¨ refers to /dev/sdb2 as in
Code: Select all
├─sdb1    8:17   1     1G  0 part /media/amigaone/5913-1FA6
└─sdb2    8:18   1  28.8G  0 part /

Firefox in my MATE 16.04.5 did not handle new desirable features of Gmail. I was advised to install REMIX. Now my Gmail works as it should, although sometimes extremely slowly.

I can drag needed files over from Xenial Xerus home directory to REMIX, but apps are a different matter. At least one I used a lot in the old MATE is, according to apt-get install, not available for REMIX. I needed to boot MATE 16.04 for things other than email, but since installing REMIX, "run ubuntu" in Uboot no longer worked. Had the REMIX install wiped it out, I wondered.

I had been puzzled by the "ubuntu" script. I remember almost nothing of the install process for the MATE it launched, but I subsequently launched it with
Code: Select all
usb reset ; fatload 0:1 1000000 uImage-cyrus ; fatload 0:1 1c00000 cyrus.dtb ; bootm 1000000 - 1c00000
Thus the puzzle: How in the world did Uboot know where to find the root program? With REMIX I need to supply a location by setting bootargs.

That remains a mystery that I hope some kind reader will solve for me, but I soon (well, not really soon) realized from the fact that I could open Places > MATE in the REMIX menu bar and retrieve needed files that the program had not been obliterated, and after a while I found it, to my utter surprise, in the fifth partition of my X5000 hard drive! I thought I had read that Ubuntu should not go on the same drive as AOS, but I must have misread. With 75% of that drive so far unallocated I know where I am going to move my REMIX to! (And free up a valuable USB slot.)

One other puzzle that I could use some tutoring on: The main hard drive used to be /dev/sda. Now it is /dev/sdc (as I had noted earlier in this thread). What makes it change? And if I remove that USB drive that currently has REMIX on it, after copying it to a /dev/sdc6, will it change again?

I guess I'm always going to need more tutoring.
