Xrandr crtc0 error, not switching resolution

Changes · 01-18-2014, 09:13 PM

I'm running Picuntu 4.5 on a MK808B Android stick. I followed these instructions to get the Mali drivers running, and it does run the GUI, but I can't change resolution. The stock apps for changing it have 1920x1080 among the ones I can select, but if I do they don't actually change it. When I try manually with xrandr I get a brief flicker and an error. Sometimes the taskbar gets extended past the limit of the actual screen, but other than that nothing changes.

Xrandr attempt to switch and error

I don't know where I'm going wrong. Can you spot any obvious mistakes?

Hi
Can you post what xrandr commands you're using? Most times 3 iterations of xrandr commands are required = newmode, addmode, and output.

I did; they're in the "attempt to switch and error" pastebin, first line. The 1920x1080 mode is already present as seen in the verbose report, I try to switch to it but it fails.

I'm afraid at this point I'm grasping at basic straws. I know almost nothing about the MK808 but a little that I've read (seems cool). I just have a fair bit of experience with hinky monitors with less than compliant EDID that I often have to jump through hoops to get to display properly. I would guess that you've already researched your monitor to know it's requirements and capabilities at given ports, so all I can is wish you good luck.
