so how to apply this patch for ubuntu or is there any chance to run monitor through bb-xm image u have said earlier

27

That's a "kernel" patch..

You need to 1st download the kernel source for your particular build..

so:

git clone git://kernel.ubuntu.com/ubuntu/ubuntu-precise.git
cd ubuntu-precise

git checkout origin/Ubuntu-3.2.0-23.36 -b tmp
zcat /proc/config.gz > .config
patch -p1 < ../../test.diff
make ARCH=arm menuconfig
make ARCH=arm uImage
sudo cp arch/arm/boot/uImage /boot/uImage

Good Luck!

If that's too much, pay someone to do it for you...

hey , the image dt-beagl-xm that i have downloaded works well with putty and it shows all the three i2cs so is there any chance to enable the hdmi of xm so that i can use monitor

29

2 hours ago i asked you for your exact monitor model, such that i
could tell you how to override it..

You refused...

model number is AC512. srry monitor is of acer

31

Add to the top of /boot/uboot/uEnv.txt

optargs=video=DVI-D-1:1024x768@60e

the 'e' forces output
1024x768 : obviously the resolution..
1280x720 (the old default..)

So try a couple..
