A unified reply to a question about the display of debian69

@tommythorn sorry for late response.
Generally, xrandr couldn’t be modified default resolution and you need add a auto script like this

root@starfive:/etc/xdg/autostart# cat default_pixel.desktop
[Desktop Entry]
Version=1.0
Name=pixel
Exec=/root/pixel.sh
Terminal=false
Type=Application
Categories=
GenericName=
X-GNOME-Autostart-Phase=Initialization
X-KDE-autostart-phase=1
NoDisplay=true

and the pixel.sh contains how to use xrandr to indicate a specific resolution like this:

root@starfive:/etc/xdg/autostart# cat /root/pixel.sh
#!/bin/sh
xrandr --output HDMI-1 --mode 1280x720 -r 50

reboot and hope that works

Hi,
have the same Issue.
I dont even get any Output.
Tried all steps mentioned here.

Here is my Post:

Got errors with cursor freezing in Debian image

Have the same Problem, none of my Displays work. On a iiyama 4k Display i get the Black Screen with a Mousecursor that freezes after 5 seconds. On a Samsung T220 that is capable of 1680x1050 i get no Output at all. The T220 only have VGA and DVI. I Use a DVI to HDMI Cable. Output of modetest: root@starfive:~# modetest -M starfive -c Connectors: id encoder status name size (mm) modes encoders 116 115 connected HDMI-A-1 470x300 1 …

@kira

1）vi /etc/lightdm/lightdm.conf
2) Add display-setup-script=xrandr -s 1920x1080 under [Seat:*]
3) Reboot the system or type “systemctl restart lightdm”

Thanks for the heads up! Worked like a charm! Dell U3219Q here …

@Michael.Zhu
I was following the steps here but didn’t make any progress.

modetest -M starfive -D 0 -a -s 116@31:1920x1080-60.00 -P 39@31:1920x1080@YUYV -Ftiles

Works for me…It displays the pattern that Tommy also posted.

However setting lightdm.conf does not lead anywhere after a reboot.
If I try running sudo xrandr -s 1920x1080 I just get the Can't open display message.

Any further advice on debugging this?

Can you try to flash a latest version of debian VisionFive 2 Debian Image 202303 Released(latest) and set the SD boot mode to start up?

[developandplay]

Thanks Michael that works perfectly!
The colors were a bit weird on initial boot up but after change the resolution that seems solved.
Oh and I needed to adjust the dip switches as you mentioned in the release post.

I see you added support for 4k resolution now.
Not sure how “hardcoded” that is.
The 1440p monitor I’m using seems to only go up to 1080p with the VisionFive 2.

[developandplay]

Ok the pink tint comes back after some minutes and can seemingly only be removed by setting the screen resolution again.
Is this a common issue?

[kira]

you can run the script under /opt and reboot.
