Unable to set proper resolution/not detecting display properly

TekGiant picture TekGiant · Oct 14, 2013 · Viewed 7.1k times · Source

This is probably the farthest removed Q&A place to ask about this, but I've tried every other reasonable and/or obvious source I can think of with no luck.

I have both a BeagleBone Black and a Raspberry Pi that I'm working with.

I'm using a Motorola Bionic Lapdock to connect to either device as it's easier in my opinion then having to have a separate full blown monitor, keyboard and mouse hooked up.

First the RPi: with no crazy configuring of any kind, when I hook up the RPi to the dock, it recognizes the dock's 1366 x 768 resolution and both the CLI and the lxde GUI run on the correct resolution.

-However-

For the BBB: when hooked up, it doesn't recognize the monitor the same way and both the CLI and OpenBox GUI are stuck in a 700x568 (I might be slightly off with that number) resolution.

I've read up on editing the xorg.conf and different functions that the "xrandr" command is capable of. When I try

xrandr -q

I get a response about it not being able to detect something with the gamma output and then what the min, current, and max resolutions are. I know the lapdock is capable of the 1366x768 but it says the max is 700x568...

My /etc/X11 folder does not have an xorg.conf file generated and I didn't want to just go start trying to make one and mess things up.

So, my question(s) would be:

What would be the best route for me to take to force the correct resolution?

For the CLI I'm not sure if resolution has anything to do with it, but I would like the text to be smaller as it would be in a higher resolution environment. And as for the Openbox GUI I'd like it to be set to the display's capable 1366x768.

Update: I've tried to run:

sudo Xorg -configure

and it fails telling me that no displays were detected. I also thought maybe I'd check the xorg.conf file on my Raspberry Pi's Raspbian Distro (seeing as how the resolution and stuff is detected fine on there), but sadly that X11 folder doesn't have an xorg.conf file; however, it does seem to have other files relating to the X server that aren't on my Ubuntu distro. Also, I tried issuing the command:

xrandr -q

on my Raspberry Pi, but it reports that it "Can't open display". So, my conclusion at this point is that I can force the resolution and/or font of the CLI and the GUI without the OS recognizing exactly what the display is, but I don't understand what I can maybe copy over or look for on the Raspbian distro that's causing it to work properly where the Ubuntu distro isn't.

Thanks for any help.

As an updated additional question, I'd wonder if there's a driver I may need that I don't have? Are there any other generic drivers that might not come stock that I could download for this? I don't know of any proprietary drivers the Motorola Bionic Lapdock would require, so if anyone might have any ideas on what to check or download in regards to drivers that could help too.

Again here's another addition: I ran the following command that was recommended on another forum to check the edid information and output when an X session is initiated.

X -verbose 6 > ~/xlog.txt 2>&1

I was hoping maybe someone experienced in this could read the following output and see if they can figure out what I need to do.

First off, I see your question is from years back. I am no linux expert. I've been using a lapdock on a rpi B and a banana pi. I experienced trouble getting the native resolution to load because of various gamma errors (I'm guessing symptoms of a another problem) when I would have added modes through xrandr. For me on the banana pi running (armbian) debian jessie these steps got the BPI to boot the GUI to 1360x768.

added these lines to /etc/rc.local

fbset -g 1360 768 1360 768 32 -t 11799 208 72 22 3 136 5
fbset -g 1366 768 1366 768 32 -t 11647 216 72 23 1 144 3
fbset -g 1366 768 1366 768 32 -t 14301 200 56 19 1 144 3

There is probably a more complete way to address this issue and I may be wrong to suggest it for a beaglebone. Good luck
