JRiver Media Center 21.0.90 for Debian (Wheezy) ARM
newbluesman:
I've been using MC on my Beaglebone for well over a year without a problem, through several OS changes and eMMC flashes. I just put the latest Debian on an SD card, booted and reinstalled JRMC21 - and when I open it, the entire window (screen, if maximized) is white. I redid everything again, but the result is still the same - a blank white patch. Any ideas would be gratefully accepted!! Thanks.

The most likely cause is that you haven't set the framebuffer color depth to 32 bit. I don't have a beaglebone, but on the Raspberry pi, it's as easy to fix as adding twoi lines to the config.txt
--- Code: ---framebuffer_depth=32
framebuffer_ignore_alpha=1
--- End code ---
If there's a similar option on the beaglebone, I would start investigating there.

Thanks - I'll do it when I get home from work and report back! FWIW, I haven't had to do this before through several setups of MC on various Ubuntus, Debians etc. I've also flashed and run Rune and Daphile on the 'bone at different times - but stuff happens.

I only know that the all white window is a sure fire sign that the framebuffer color depth is wrong. On some of my ODROID SoC's the issue was uncorrectable as their drivers only supported 24 bit output, which ruled them out for MC use. I'm not sure why it would work one day and not the next, but I would suspect a graphics driver/X11 update or change.

It's not the entire screen that's white - it's only the MC window. If I maximize it, the entire screen is white but otherwise, only the MC portion is affected. The rest of the display is black with the BB logo and taskbar normal, and all other GUIs display and work fine.
