Hello,
im having a large amount of trouble with setting up the Reterminal the way i want. At the moment specificly the drivers are breaking PI-OS.
What is happening: After installing the default 64-bit (!) PI-OS via raspberry pi imager, the system boots normally, but the lcd-display doesnt work. When installing the drivers in the way it is proposed by seeedstudios "Install reTerminal drivers after flashing new Raspberry Pi OS/ Ubuntu OS or Other OS" guide, the device boots, but the lcd doesnt work, everything is very laggy, the desktop symbols move underneath the taskbar and the resolution is wrong. When trying to open arandr/screen configuration i get the error from xrandr that “Randr” extension is missing.
When i comment out the “dtoverlay=reTerminal” line in /boot/config.txt, arandr works after the reboot. If i comment it in i get the error again. So it probably has to do with the drivers.
For some reason when booting, the raspberry shows that its booting the “32-bit” version of Pi-OS. If i install the “shipped with reterminal” image, downloaded from the seeedstudio site, it also says 32bit.
Doesn´t seem to make any problems related to that tho.
Ive tried Ubuntu OS from the pi imager software, but there the drivers dont even install properly. Im getting multiple errors which i can reproduce, but i dont have the logs on me right now.
Ive tried the 32bit version of pi-os / reterminal pi-os and have the same problems.
Ive tried also installing ubuntu the way descripted in " Q10: How can I install Ubuntu on reTerminal?", but the scripts provided do not make the lcd-screen work.
All these problems appeared after a regular ive had a regular “Pi-OS Reterminal” installed, which i accidently bricked while trying to fix the rotation of the screen. Starting with the next image installation i cant get the reterminal LCD to work.
This is my second problem: The rotation of the LCD-Screen seems impossible to fix and using a second display often does not work or works poorly. No matter what i do, at some point it reverts to its default orientation.
At first i disabled the iio-sensor-proxy service, specifically the acceleromotor, which caused the screen to rotate when the device was physicly rotated. Then i set the rotation in arandr to right, so the screen is rotated in the right way. So far so good. Worked fine until i connected a screen to the hdmi port. The screen instantly reverted to its original “portrait” orientation. Manually setting the orientation back to “right” worked, but after the next boot it reverted back to the portrait orientation. Setting lcd_rotate or display_lcd_rotate in the /boot/config.txt doesn`t work either.
But, for some reason, the Pi-OS/Ubuntu OS/Gnome login screen is always in the right orientation.
Even though even the console is always wrongly rotated when booting into terminal instead of the GUI in PI-OS.
Another weird behavior, ive tested 3 displays:
- An LG with 2560x1080, which is stuck at 640x480 in arandr for some reason (HDMI)
- A Waveshare touch display (HDMI) which doesn`t work at all (works with ubuntu (not ARM) normally)
- An old AOC 1920x1080 (HDMI) which works 100% correct with arandr
This was a lot, i hope someone can help me with all my confusion.
Have a nice day!
I think it has something to do with the firmware on the board the CM4 sits on which does not like the “apt upgrade”. If i remember correctly it was somewhat broken after that.
