I have a Raspberry Pi 3B running Fedora AAarch connected to my TV.
After installed the latest version 31 updates, the display went weird on me. Monitor preferences list an "unknown" monitor with resolution 1824x984 and refresh rate 77 Hz, and colours are all wrong. What should be red or orange is blue, blue is red or brown, and I'm not really sure what everything else I see on the screen is supposed to look like, but the greens may be more or less right.
Any idea what's going on?
I'm using the MATE desktop.
If I connect my CentOS 7 laptop to the same HDMI port using the same cable, everything seems just fine.

No, but then I've not ran F-31 on a RPi for a month or two, I tend to move to dev releases pretty quickly and don't regularly use desktop UXes in testing.
First question is what updates were applied, the most likely candidates are kernel and mesa. If you reboot into the previous kernel does it start working again? How long between the updates, was it days/weeks/months since you last updated and rebooted?
I'm using the MATE desktop.
Custom image? Anything else custom or did you start with minimal/workstation/xfce and cross grade?
If I connect my CentOS 7 laptop to the same HDMI port using the same cable, everything seems just fine.
Well that's a mostly irrelevant comparison because none of the software is anywhere near Fedora.

So, do you reckon the Fedora 32 Beta will be usable?
First question is what updates were applied, the most likely candidates are kernel and mesa. If you reboot into the previous kernel does it start working again?
Now, there's something I haven't figured out how to do very easily, as I'm dumb enough to rely on a Bluetooth keyboard... Anyhow, I set the default to the last kernel but one via grubby, and rebooted. Still have the same issue.
How long between the updates, was it days/weeks/months since you last updated and rebooted?
It's been a couple of months, I think.
I'm using the MATE desktop.
Custom image? Anything else custom or did you start with minimal/workstation/xfce and cross grade?
This is a system that has been upgraded across several releases. I started off with an image available through arm.fedoraproject.org, or an earlier generation of that site - like the ones available under "Desktop Computing" now. I think it was F28, but I'm not 100 % sure. Obviously, I kept the image, but who can tell where I put it?

Depends on your definition of near, doesn't it? But it was mostly not a comparison at all; the point was that there is not likely to be a problem with the TV itself or the connection to it.

I've now tried a clean(er) install on the system, and still have this problem. Essentially, what I did was
1. Download "Fedora Minimal" and write it to the SD card. 2. Boot up the system in text mode 3. dnf groupinstall MATE base-x 4. systemctl set-default graphical-target
After this, I have a similar problem. Somehow the colours don't look quite as bad this time, but the resolution is clearly not right. xrandr reports
Screen 0: minimum 1824 x 984, current 1824 x 984, maximum 1824 x 984 default connected 1824x984+0+0 0mm x 0mm 1824x984 77.00
I'd really like to track this down further to a component the may cause the issue (or log that could tell me what's wrong), but quite frankly, I don't know where to start looking. One clue, though, I installed and ran "monitor-edid", and it said:
[toralf@lille-hjelper ~]$ sudo monitor-edid [toralf@lille-hjelper ~]$
Yep, that's right. Absolutely nothing. In earlier releases, it has given me actual data for the display.

No, wait. The problem is actually intermittent. Sometimes everything works (after a reboot), and I just found that when it does, I have
$ ls /dev/dri/ by-path card0 renderD128
$ ls /sys/class/drm card0 card0-HDMI-A-1 renderD128 card0-Composite-1 card0-Writeback-1 version
In cases where I get the problem, on the other hand, /dev/dri is missing, and /sys/class/drm only contains the version file.
