Firsly it is worth noting that I am not a Linux expert... in an earlier life I did a lot of development for PowerPC with VxWorks and ThreadX RTOS... I have just returned to a bit of hands on to build a demo system...
So: I have just purchased the Efika MX... and at first was pleased (surprised) when out of the box the screen came up and I configured machine details [time zone etc...] However, once the machine proceeded past this phase of boot up it black screened.
I have now read numerous posts about black screening...
i) Some of them go back to 2010/2011 - and I am surprised that the problem is still happening. I have tried quite a few different monitors and TV's [with HDMI input]. [Note: for most monitors I am using a HDMI to DVI connector]
Q - Is there any updated OS revision / new drivers that can be installed to rectify this problem?
ii) The screen worked fine during configuration phase, albeit not with the greatest resolution - i guess with basic HDMI port drivers. it would seem that once the full suite of HDMI drivers are installed the problems occur.
Q - Is it a back up solution to disable the installation of these drivers and to run with those used during boot phase?
iii) I can login to the Efika via the serial port so it is coming up OK without the screen working... can I make any changes once booted [as temporary solution] to enable my monitor?
iv) Any other thoughts on this subject are welcome please?
I really like the packaging and the spec of this device - and for the prototype I am producing was really hoping for as close to an OOTB experience as poss - just wanted to write the application layer and assumed such an established device would be perfect! Any help would be greatly appreciated.
