    I work with Raspis, the Parallax Propeller board and a wide variety of add-ons, hats, modules and you-name-it for both and I write-up reviews from what I find. I'm used to the amount of research, tweaking, hacking and sometimes disappointment from attempting to use these things. You'll find five drivers from official to tweaked-version-of-the-favorited-tweak, eventually getting the right combination of settings in some obscure file somewhere. The most frustrating time is waiting for some part to arrive, something they *could* have been mentioned on the description (like a logic converter, say). <_< I will say that I'm pretty familiar with the inner workings of Raspbian Jessie.

    The chassis is for a Raspi supercomputer, for what it's worth. Once finally assembled, you guys will see it after I do.

    Looks like this thread discusses a promiscuous logging issue with several people complaining of an unresponsive Raspberry if they leave it on for hours.

    I've noticed that my own /var/log/syslog was filled with "rsyslogd-2007: action 'action 19' suspended, next retry is..." messages like these people. I've adjusted my /etc/rsyslog.conf as they suggested and it no longer logs this type of message.

    More info

    There's a bug with /dev/xconsole which is self-perpetuating an error, which tries to log that error, which tries to use /dev/xconsole...

    You can easily hook whatever HDMI source you have to it to test. With a bit of luck just disconnecting/reconnecting the cable in the process will fix it :)

    Hello,

    I just changed my broken LCD screen with that model and my touch screen is not oriented like the display? Any idea how I could fix that? I tried a bunch of thing like touchscreen-inverted-x touchscreen-inverted-y in the boot.txt but no success

    Yea, the touch sensor has to be configured with the correct oreintation (the boot.ini) and calibrated.

    For some reason, only display_rotate=2 works on my side and the subsequent lines for touch dont do anything:

    dtoverlay=rpi-ft5406,touchscreen-inverted-x=1,touchscreen-inverted-y=1

    Thats the line I had already tried previously :(

    Im starting to wonder if the screen I bought has a defect with the touchscreen. Its kind of weird that the default touch is not aligned with the display at all and that no fucntions affecting its orientation seems to work.

    If this were just a Pi issue I would say update to the latest version of Raspbian (Buster) as well, but if you do that on a C2 or R2 the Robo menus will cease to function because those are driven by an outdated version of a plugin used on OctoPi that is no longer supported or developed.
