What happens if you boot normally and run:
Code: [Select]
xrandr --screen 0 --size 1440x900

By boot normally, do you mean boot with the radeon.modeset=0 added? Because otherwise I don't have a terminal.
And doesn't using radeon.modeset=0 prevent the radeon driver from working or am I misunderstanding what it does?

yes with radeon.modeset=0

Well, this is weird. When it booted into grub, I didn't get the red Peppermint themed grub screen I've been getting. It was just black with blue text. Maybe because I had some updates in my regular distro before booting back into Peppermint? But anyway, I added the radeon.modeset=0 like I have tried many times in the past couple of days but this time it booted into the correct resolution! I didn't try the code above because the resolution is now correct. I didn't trust it since I didn't change anything so I rebooted, added the radeon.modeset=0 again, and it still booted into 1440x900.

So I guess I just need to know how to permanently add the radeon.modeset=0 so I don't have to edit the line in grub each time? Although, I still don't trust it, LOL!

My clipboard icon isn't in the tray and I don't see it in the menu or in the things to add to the panel. How do I get that back?

Also, it still says the radeon drive is unloaded so will this driver it's using be enough to handle light games like the radeon one did?

Hard to say about the games, you'll have to be the judge of whether the ati driver is as good as the radeon driver.
(which is really shorthand for "I haven't the foggiest")

To make it permanent...

Open a terminal and run:
Code: [Select]
sudo pluma /etc/default/grubfind the line that reads
Code: [Select]
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"and change it to
Code: [Select]
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.modeset=0"SAVE the file and exit pluma.

Back in the terminal run:
Code: [Select]
sudo update-grubReboot to test.

That didn't work. It booted to a black screen again. So I booted again and hit e to edit when the grub menu came up and the radeon.modeset=0 wasn't in the line. I added it so it would boot, then once booted I opened the file to make sure the changes I'd made in Pluma had saved. They had, the line is there, but it still won't boot correctly.  ???

I'm going to mark this solved since I can get it to boot into the graphical interface if I edit grub on boot. I'm not too happy with the driver situation but I"ll probably put an Nvidia card in it soon anyway since AMD has stopped offering the proprietary driver.

You should not have to keep manually entering it at the GRUB screen .. can you post the contents of your:
Code: [Select]
pluma /etc/default/gruband
Code: [Select]
pluma /boot/grub/grub.cfg
Please remember to encapsulate the output in "code" tags when posting it, to preserve the formatting.

I installed another distro, a non-Ubuntu based one (OpenMandriva) alongside, to see if the radeon driver I normally use on that computer would work, and it took over grub and Peppermint is now keeping the radeon.modeset=0 setting when I reboot. OpenMandriva did boot into the graphical desktop with the default radeon driver but my Wacom tablet didn't work and there was some other weirdness and no help to be had on their forum so I replaced it with Maui. Maui will not boot into a graphical desktop without the radeon.modeset=0 setting and even with that, it only offers the 1020x768 just like Peppermint did at first.

 I'm not expecting help with this here. I just thought I'd let you know what was going on. It's interesting that the Ubuntu based distros won't work with the radeon driver but a non-Ubuntu based one does. The older version of Netrunner that is also on the same machine is Ubuntu based and uses the radeon driver, so something has changed with the newer versions.

Yeah there were some major changes to all the ATI/AMD open sources drivers because of the new xorg version in 16.04

Is the resolution working now ?

In Peppermint, I can now set it to the correct resolution when booting with radeon,modeset=0, even though I couldn't at first and I didn't change anything.  In Maui, I cannot set it to the correct resolution with radeon.modeset=0 but I can if I boot into recovery, just like with Peppermint at first. I wish I knew what made it start working in Peppermint so I could do that in Maui, too.  It's frustrating.

I wanted to update this post with some new info, in case it helps anyone else having the same problem. I'm also running Maui on another partition and had the same problems with black screen on boot. With some help from leszek over there, I installed a newer kernel (4.7.2 kernel) from http://kernel.ubuntu.com/~kernel-ppa/mainline/ and with that kernel, the black screen problem seems to be solved! I haven't tried it on my Peppermint install because I'm not sure yet if I can run that kernel with no other issues.  It may work with less new kernels too, but that is the one suggested to me and the only one I have tried so far. I thought it was worth mentioning here.
