DWC Interface to SBC resizing with M81 or ATX off
-
Thanks. Probably one for @chrishamm
-
The question is how do you resize the web interface. Do you start Chromium with an extra command line parameter? Using a dev pixel scale has worked well AFAIK, see https://forum.duet3d.com/topic/13693/duet-3-pi-hdmi-touchscreen?_=1590147732853
I made a change to DWC2 in 3.1.0 to disable manual zoom so double-clicks on cell phones don't cause any zoom. So I am quite surprised to see this happening on your setup.
-
@chrishamm I resize the web interface manually using a mouse and keyboard by holding the keyboard control button and scrolling the mouse wheel a couple clicks. The slightly smaller size allows the 7" Pi display to provide more information.
As far as starting Chromium I'm full stock no changes to the command line. I do get a notice that Chromium needs an update, but shouldn't apt-get update/apt-get upgrade cover that?
-
Yes, updating Chromium via apt-get should work but I have not yet checked if the latest version from the Raspbian mirrors is up-to-date.
Please try to change the Chromium start script and don't use manual zoom. I suspect that manual zooming can cause the glitch you're seeing.
-
Can you give a little more detail on changing the Chromium start script? The details here https://forum.duet3d.com/topic/13693/duet-3-pi-hdmi-touchscreen/6?_=1590147732853 are kind of cryptic as to that method. Will edit accordingly. Thanks.
-
@chrishamm To confirm, this is what needs to be edited?
# If you want to make the DWC on your attached touchscreen bigger: sudo nano /usr/bin/launch-dwc # Add this at the end of the line --force-device-scale-factor=3 # You can use fractions, like 2.5. Change and reboot until it looks good to you. -
Yes, append that to the line where
chromium-browseris started and runlaunch-dwcto check your changes. -
Thanks! 0.85 scale looks good - will run a print or two to see if this corrects things.
-
@chrishamm ran a couple prints and after adding the fix, the display still zooms out of control
Also DWC becomes unresponsive -
@Wally I am sorry to hear that but I find it hard to believe that this isn't caused by your Pi config or display. If you had to make any system adjustments for the display, please share them as well as your config and print file. I'll try to reproduce this problem then.

@chrishamm here you go:
Note the screen zoom didn't happen with RRF 3.x Release candidates up to #10, I jumped from 10 to 3.1.0, and then the current release 3.1.1
I had installed xscreensaver with
sudo apt install xscreensaverBut uninstalled xscreensaver it when this started happening.
No change after uninstall.my config.g file:

@chrishamm I have a work around; however, it makes me ask what was done "to disable manual zoom so double-clicks on cell phones don't cause any zoom" ?
My work around, use:
--force-device-scale-factor=2.7AND disconnect my USB mouse & USB Keyboard connected to the Pi. Then power on the system & boot, and DWC start, then connect mouse and keyboard. After doing that, the zoom problem doesn't appear. The 7" display with touch screen appear to be setup for touch screen, larger scroll bar, buttons, etc.
Does your tests include using a USB Mouse & Keyboard? -
@chrishamm Follow up, verified that if a mouse is attached to the Raspberry Pi USB port, the re-zoom happens, confirmed with 3 different mfg of USB mouse (or mice?) . No mouse - no re-sizing or zooming ...
-
@Wally I always have a mouse attached to my Pi 4 and I have never seen this problem on my setup.
-
@chrishamm - finally figured this out. I was using 5V from the 6HC mainboard to power my display. During power off with M81, the 5V line voltage to the display would vary a lot (enough to cause the problems seen). Connecting the display to a separate (dedicated) 5V power source has eliminated the problem reliably. Probably should have used an O-Scope to quantify the variation; however, the cleaner power clears up the display.
