Unable to open GUI in Maverick 10.10 with BeagleBoard XM RevA

GoogleGroups

Hello,

recently I received my beagleboard XM. I've installed Maverick 10.10
demo following the steps showed in:

http://elinux.org/BeagleBoardUbuntu#Maverick_10.10_2

It seems the installation has been successful, no errors loading
kernel and mounting FS, but I can't see the GUI on my dvi monitor.

I've attached the bb to a DVI monitor by a HDMI-DVI cable. I also have
attached the bb to a PC (RS232-USB) in order to debug. When I turn on
the bb I can see uboot and kernel booting in the shell of the PC and
nothing in the DVI monitor. When the FS is booting, the monitor turns
on and I can see the same image in both: PC and dvi monitor. Later, I
can see in the dvi monitor how the GUI begin to boot but few seconds
later the image disappears.

In abstract:

- Ubuntu seems to be well installed.
- DVI monitor runs ok (at least text).
- GUI doesn't run.

I've proved with 3 different monitors and 2 different HDMI-DVI cables,
but still not working.

I look forward a little of help.

Thanks a lot.
Manu.

add more detail about above

I assuming you actually built the GUI version

I installed a demo image from same place. Does the command prompt work and display a file sytem with ls?

but it was required I update after getting networking up

Thank you Mark,

What does mean "build the GUI image"? I did:

setup network: "sudo ifconfig -a" and "sudo dhclient usb1 or eth0"
sudo apt-get update
sudo apt-get install xfce4 gdm xubuntu-gdm-theme xubuntu-artwork
xserver-xorg-video-omap3

I didn't do:

Advanced: Build Image:

fixup.sh: http://rcn-ee.homeip.net:81/dl/updates/omap-image-builder/tools/fixup.sh

Built with rootstock trunk (ARM native mode, run directly on
beagleboard):

sudo ./rootstock --fqdn omap --imagesize 2G --dist maverick --serial
ttyS2 \
--login ubuntu --password temppwd \
--seed btrfs-tools,i2c-tools,nano,pastebinit,uboot-envtools,uboot-
mkimage,usbutils,wget,wireless-tools,wpasupplicant \
--script fixup.sh --components "main universe multiverse" \
--kernel-image http://rcn-ee.net/deb/maverick/v2.6.35.9-l9/linux-image-2.6.35.9-l9_1.0maverick_armel.deb

...because I thought it would be an extra option.... besides: I didn't
understand what means (how to execute):

fixup.sh: http://rcn-ee.homeip.net:81/dl/updates/omap-image-builder/tools/fixup.sh

Network was running ok. I can see the prompt in the console of the PC
(debug port) but not in the DVI monitor (beagleboard).

As you can guess: I'm almost newbie in unix systems.

Thank you.
Manu.

Everything is good up to hear and exactly what i'd expect you to see
with those images I've posted..

Later, I
can see in the dvi monitor how the GUI begin to boot but few seconds
later the image disappears.

What 'gui' are you running that isn't appearing? as the minimal image
by default doesn't have a gui...

In abstract:

- Ubuntu seems to be well installed.
- DVI monitor runs ok (at least text).
- GUI doesn't run.

double check the 'boot.scr' in the fatfs parition of the sd card..

compare with: http://elinux.org/BeagleBoardUbuntu#U-Boot_Boot_Scripts

Regards,

I can't directly edit boot.scr since is a binary file... but I found
the way in this link:

https://wiki.ubuntu.com/ARM/BeagleEditBootscr

Anyway... I formatted the SD and installed all the system again:now I
can see Ubuntu's Desktop :wink:

By now the only inconvenience I can see is the color depth: I'm not
sure if the monitor works ok (never used til now) or I have to change
from RG565 to RGB666 or RGB888. I will prove...

Thank you very much Robert and Mark.

Regards.

Hello again,

my problem with the monitor was solved :slight_smile: ...the digital input of the
monitor doesn't work right :frowning:

I decided to install the full image for OMAP3:

https://wiki.ubuntu.com/ARM/OMAPMaverickInstall

Looks very nice but the desktop runs quite slow (netbook edition).

Does anyone can explain me what I should do to get the desktop
(gnome) of the PC version of ubuntu.

Thank you.
