I tested a lot and there is a very high chance, that the problem is the DVI-monitor. I tried 2 different card-brands, Transcend and Patriot I tried 2 DVI-monitors and 1 HDMI-monitor I tried 3 Armbian images Every time I use a DVI-monitor the installation doesn't start with similar behavior of the power led of the monitor (on, off, different times) At the end I tried the newest Armbian_22.08.7_Rpi4b_jammy_current_5.15.74_xfce_desktop.img.xz with an HDMI monitor and everything worked fine. Putting this card, working with HDMI, in another PI400 with a DVI-monitor, it doesn't boot and the power led blinks as described. So maybe there is a developer, who can test with a DVI-monitor? On the other hand, there is 2022-09-22-raspios-bullseye-arm64-lite.img.xz which works with DVI. So maybe comparing the code could help. Of course I can do test with a special image, that outputs some log or use Bullseye to do some queries.

I have taken it from Xubuntu, since I had problems via the settings-interface to press alt+print. The other way is to use settings / keyboard / shortcuts (don't know the exact names in English). I have no problems with ctrl-print, but with alt-print definition using the settings.

I want to add, that after every trial I flash the image new and before I create 1 new partition table, so the old 2 partitions don't exist anymiore when flashing.

Armbian_22.05.4_Rpi4b_jammy_current_5.15.48_xfce_desktop.img.xz from the archive has the same behavior, but it could take longer that the monitor awakes, but then led on / off a.s.o How do I do a headless installation? SSH has to be allowed or is it allowed by default? Please note, I am talking of the desktop version. With Armbian_22.05.4_Rpi4b_jammy_current_5.15.48_xfce_desktop.img.xz putting in the sdslot, there is no network to connect. Read a little bit, but didn't find a bug. I fear it is the old hardware or maybe micro hdmi to dvi. What I can do else to use the other PI400 with the HDMI-Monitor and check if this works. Since this is so short after starting the install-card, there is no log or anything I can offer, just describe what happens. For me it looks like that the monitor is searched with a valid configuration and none is found.

Unfortunately not for me, same problems as described at After starting the montitor switches between on and off. I am using the 19"-monitor at the moment. It doesn't help to ignore that and wait untail there is an output at the monitor. Is it possible to do a headless installation with the desktop version and do the 1st steps via ssh?

Thank you very much, that is very good to hear. Did you test it with 4k too? Are you interested in the problems after an installation, which I had? In the meantime I managed most things, except 4k. Compare my other postings too. I think for a beginner, a few things should work out-of-the-box. My other PI400 worls fine now with Armbian installed with Armbian_22.11.0-trunk_Rpi4b_jammy_edge_5.19.11_xfce_desktop.img.xz. Just a feedback, I know this is not supported. Thanks a lot, I will give you feedback ASAP, maybe tomorrow. For unknown reasons I could not install Armbian_22.05.4_Rpi4b_jammy_current_5.15.48_xfce_desktop.img.xz, nothing happened on the screen, so I do a test install with 2022-09-22-raspios-bullseye-arm64-lite.img.xz at the moment to be sure not to be fooled ny a broken hardware. I am back with my 19" monitor, which is preferred because of the size.

Here is a solution: Put these lines into ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml if it does not exist <property name="&lt;Alt&gt;Print" type="string" value="xfce4-screenshooter -w"/> <property name="Print" type="string" value="xfce4-screenshooter"/> <property name="&lt;Shift&gt;Print" type="string" value="xfce4-screenshooter -r"/> You can add the key via settings too, but to add alt-print can be a little bit tricky. Try to do it in 2 steps, first alt, then with editing add print. For me, editing the file is easier.

See thread The XFCE download was removed now.

I know https://armbian.hosthatch.com/archive/rpi4b/archive/ but these files are a lot older, 5.15.48

It is no problem to install 2022-09-22-raspios-bullseye-arm64-lite.img.xz, so I have no broken hardware, would be really happy to install Armbian 😉

I am only sure, that Armbian_22.11.0-trunk_Rpi4b_jammy_edge_5.19.11_xfce_desktop.img.xz works with my hardware, maybe Armbian_22.11.0-trunk_Rpi4b_jammy_current_5.15.70_xfce_desktop.img.xz too. For sure I have problems with newer Armbian_22.11.0-trunk_Rpi4b_jammy_current_5.15.73_xfce_desktop.img.xz and Armbian_22.11.0-trunk_Rpi4b_jammy_edge_5.19.15_xfce_desktop.img.xz So where can I download older versions?

Back again to stable: Armbian_22.11.0-trunk_Rpi4b_jammy_current_5.15.73_xfce_desktop.img.xz I cannot install with a Nec Multisync EA232WMi (FHD, 1920x1080) too The monitor power led shows permanent on, the screen is black for 5-10 min. So maybe the problem is the micro-hdmi dvi cable?

Same problem with Armbian_22.11.0-trunk_Rpi4b_jammy_edge_5.19.15_xfce_desktop.img.xz

Armbian_22.11.0-trunk_Rpi4b_jammy_current_5.15.73_xfce_desktop.img.xz Raspberry PI400 Viewsonic VP930 (1280x1024) I checked the sha-sum and flashed 2 times a Patriot SXDC-128GB-card. When I boot the PI400 the monitors LED changes from green (power on) to yellow (standbye) for half an hour, when I start the PI400. It looks like there is a problem with this old monitor which supports 1280x1024 only. Don't know, if the boot routine checks the monitor, but the green LED can stay for 2sec, sometimes for 30sec. BTW Xubuntu 22.04 with an SSD works fine with the same hardware.

CRTC: 0 CRTCs: 0 I would like to setup 4k with a PI400. I found https://docs.armbian.com/User-Guide_Fine-Tuning/ and followed the instructions Did I something wrong, or is this simply a bug?

I con do a screenshot with scrot and a terminal, but a screenshot with the P400 and PrtScn-Key does not work. Can anybody help me please?
