I've now tried a clean(er) install on
the system, and still have this problem. Essentially, what I did
was
- Download "Fedora Minimal" and write it to the SD card.
- Boot up the system in text mode
- dnf groupinstall MATE base-x
- 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
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 ~]$
[toralf@lille-hjelper ~]$
Yep, that's right. Absolutely nothing.
In earlier releases, it has given me actual data for the display.

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?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.
