Ubuntu Jaunty Xorg Display Issue

Samuel · December 9, 2009, 4:09am

I installed firefox, xterm and openssh-server on my Ubuntu 9.04. No
else.

RobertCNelson · December 9, 2009, 4:14am

I bet xterm brought in a package that conflicts with it.. I'll test
that tomorrow..

It should be pretty safe to force it.. "sudo dpkg -i --force-all"

Hi Robert,

Yes that is correct. I can't seem to remember what happened with the
fbdev. I am sure it didn't work correctly (I would have cheered if it
did that!). I believe it failed with the display flickering.

Regards,
Neel

HI, Nelson:
omapfb works well in 9.10. Thanks!

On 9.04 I re-do my SD card and avoiding installing xterm. After "sudo
dpkg -i --force-all xserver-xorg-video-omap3_0.1.1-2_armel.deb" and
reboot, GDM is failed to be launched.
When I manually start GDM, I get those from shell
ubuntu@beagleboard:~$ gdm
gdm[2644]: WARNING: GDM file gdm-daemon-config.c: line 2042 (): Cannot

sudo gdm is also tried, still get failure:
ubuntu@beagleboard:~$ sudo gdm
gdm[2471] GDM already running, Aborting!
GDM already running, Aborting!

Since this issue only on 9.04, I think I will switch to 9.10
Thanks for quick help!

Samuel · December 10, 2009, 8:21am

Hi, Nelson:
I followed SGX Video Acceleration guide to install something in Ubuntu
9.10:
wget -c http://rcn-ee.net/deb/kernel/beagle/karmic/v2.6.31.6-x6.0/omaplfb.ko
wget -c http://rcn-ee.net/deb/kernel/beagle/karmic/v2.6.31.6-x6.0/pvrsrvkm.ko
sudo mkdir -p /lib/modules/2.6.31.6-x6.0/kernel/drivers/gpu/pvr/
sudo cp *.ko /lib/modules/2.6.31.6-x6.0/kernel/drivers/gpu/pvr/
sudo depmod -a omaplfb

(I didn't update my kernel since I assume my 2.6.31.6-x6.0 kernel is
up-to-date)

Everything is ok, while I didn't find any performance boost on GNOME.
I just curious about what's expected effect when SGX Video
Acceleration enabled? How to identify SGX Video Acceleration works?

Thanks!

RobertCNelson · December 10, 2009, 12:59pm

Hi Samuel,

You won't see any boost in the current GNOME.

You can check by "dmesg | grep PVR" or by running the demo's in the SDK..

Hi, Nelson:
I already get code from https://code.launchpad.net/~beagleboard-kernel/+junk/2.6-stable
via bzr.
I found following content from src folder:
build_deb.sh
build_kernel.sh
build_sgx_modules.sh
create_diff.sh
diffs (folder)
patches (folder)
patch.sh
readme.txt
sgx (folder)
sync_angstrom_patches.sh
system.sh.sample
version.sh

How can I build a kernel via menuconfig? I didn't find step guide from
readme.txt.
Need I manually download untouched kernel src and, manually patch and
execute some batch?
Any hint?
Thanks a lot!

Samuel · January 20, 2010, 1:00pm

BTW, I am doing on a X86 linux machine, anything special need I step
up for cross kernel compile beside rootstock?
Thanks!

RobertCNelson · January 20, 2010, 1:05pm

run build_kernel.sh, it'll complain about missing things and tell you
what to do.. After those dependences are met, run it again and it'll
download kernel patches and patch accordingly and bring up menuconfig.

Regards,

RobertCNelson · January 20, 2010, 1:06pm

Just a cross compiler... Read system.sh.sample...

Samuel · January 20, 2010, 2:25pm

Thanks Nelson for quick help!
I assume that: To setup tool-chain(OE), I only need following
angstrom step 1-2 of http://www.angstrom-distribution.org/building-angstrom
and copy system.sh.sample to system.sh
then execute build_kernel.sh

Thanks!

RobertCNelson · January 20, 2010, 2:33pm

Actually all the way to Step 3 : "MACHINE=beagleboard bitbake
base-image" as we need a 'good' cross compiler... Otherwise you can
use CodeSoucery's Cross compiler, just download and extract it. Then
change the CC line in system.sh to where you built angstrom, or
extracted CodeSoucery...

Regards,

Samuel · January 21, 2010, 3:55am

Thanks, I choose CodeSoucery's Cross compiler, build_kernel.sh and
build_sgx_modules.sh works fine, while I got error of build_deb.sh

......
HOSTLD scripts/kconfig/mconf
scripts/kconfig/mconf arch/arm/Kconfig

*** End of Linux kernel configuration.
*** Execute 'make' to build the kernel or try 'make help'.

./build_deb.sh: line 89: make_uImage: command not found

Any idea?
Thanks!

RobertCNelson · January 21, 2010, 3:58am

Yeah, i saw that when i merged 2.6.32.4 to stable... either do a bzr
pull (it's fixed), or remove that line and the one following it and
replace it with make_deb

Regards,

Samuel · January 21, 2010, 4:39am

Hi, Nelson:
I followed you step, now my ./build_deb.sh looks like:
if [ -e ${DIR}/system.sh ]; then
. system.sh

  dl_kernel
  extract_kernel
  patch_kernel
  copy_defconfig
  #make_menuconfig
  #make_uImage
  #make_modules
  make_deb

I get another error :
...

cc1: error: unrecognized command line option "-mno-thumb-interwork"

make: *** [debian/stamp/conf/minimal_debian] Error 2

I guess I should set my arch to beagleboard in someplace, while I
don't know the equivalent of "MACHINE=beagleboard bitbake base-image"
of CodeSoucery's Cross compiler.

Any more guide?

Yeah, run it natively on an any arm based device...

Line 9 Warns: echo "This should be run natively on arm"

However you can make it work by changing line 74: change:
"--cross_compile -" to "--cross_compile=${CC}"

Or do a bzr pull, since make-kpkg is being replaced by deb-pkg and
with 2.6.32 i've converted it...

Regards,

RobertCNelson · January 21, 2010, 2:11pm

Followed guide to change line 74 of cross_compile and get following
error after 2 hrs building:

Your system has issues, that is slow... The beagle can do it in 2-3
hours... build_kernel.sh usually takes me 2-3minutes MAX with ccache
enabled... I leave deb generation to my actual arm builders...

Weird... Well it builds just fine on arm:

http://rcn-ee.homeip.net:81/dl/farm/log/archive/2.6.31.11-x11.0_1.0-jaunty.txt

In any case, I fixed this yesterday when i merged 2.6-dev into stable...

Using Angstrom's Cross Compiler...

Update your bzr repo...
