I am trying to install Ubuntu mate on my rpi2. But so far, I am only getting a black screen (I don't even see a the colorful splash screen) I installed NOOBS on my MicroSD card to ensure that the card is not faulty, and NOOBS booted up instantly. I cross checked the md5 hash from Ubuntu mate's website, so my download was not corrupted. And since I am using HDMI to DVI-D cable, I un-commented the line hdmi-force-output=1 in config.txt (There was no need to do this step while installing NOOBS) I also removed all the peripheral devices (only HDMI & power cable are there at boot) And also the green light blinks for a few minutes, and now only red light is on.

uncomment #hdmi_safe=1

This should work. I have seen similar reports, and suspect there is some difference in the Ubuntu Mate.

If this gets you a display, you can explore the modes available.

  • It worked! Thanks. Although the display resolution was very low. But I fixed that in config.txt I am guessing it's a bug in mate?
