Only this time I used the firmware files from the Meego CE image.

- Wireless works like it should
- Keyboard is OK now (I can type numbers)
- Stable, not a single crash for over two hours

However it's still VERY slow.
It boots up fast but after login to Unity it will become a nightmare:P
Firefox takes op like 2 minutes to open, and 3 minutes before I can type in a URL
"top" shows me that Xorg, gnome stuff and Unity are taking up all of my memory and cpu usage.

I already tried setting elevator=noop and using ext4 for rootfs with noatime but no luck in getting it faster.

I'm going to install the Meego CE image onto my NITDroid partition and rip out the sgx drivers/xorg config to see if I can get EGL working in Ubuntu.

Install lxde, I did that, and ubuntu become nearly as fast as maemo. Have in mind "universe" repo (where lxde resides) is commented in /etc/apt/sources.list, you should enable it manually

How do you emulate right mouse button in Ubuntu?

Code:

export GTK_MODULES=libgtkstylus.so

or something else?

STATUS: Booted-gdm-lxde
REVISION: 77, unchanged
MICROSD: 8 Gb, class 10
BOOTLOADER: U-Boot for Nokia RX-51 with BootMenu (updated version 2012.04)
OPTIONS:
selected_image_source: ubuntu-daily
selected_firmware_source: meego
dist_upgrade: 0
selected_kernel: stock (later purged and installed: http://talk.maemo.org/showpost.php?p...&postcount=151)
boot_parameters: root=/dev/mmcblk0p3 rootwait console=tty0 omapfb.vram=0:2M,1:2M,2:2M mtdoops.mtddev=2 nosplash elevator=noop panic=20

At the first bootup I had to do the first time configuration (timezone, language, etc...) it worked quite well but after I wasn't able to log in so I have instaled gdm and lxde. I also installed vlc, Midori, ubuntu-restricted-extras, synaptic. The keyboard layout works and I can switch to tty8 (ctrl+fn+volume) but I cannot get back from it. Some errors occour but I think they will disappear after I update the system

I can browse the web quite well with Firefox not Midori (strange?). During the first few boots the sound semmed to be broken, but when I was trying out the capability of the browsing realised that the sound started working - Facebook chat sound was working. I was able to mount the MyDocs directory and acces all my files. Picture viewer works just fine (fast zooming, bit slow opening).

EDIT:
Cpu scaling is working 249-600mhz. I was able to toggle the screen brightness, the keyboard lights and when I plug in a charger the phone recognices it, but won't charge the battery. I was able to read some data about the battery (charge,voltage,%). Basically I was just looking around in /sys/class. I'm wondering if someone could write a small control-panel like application from we can control screen brightness, keyboard lights, read battery infos.

Keep up guys because this is getting really awesome!

I have made a sort video about the keyboard leds. I was able to light up the keyboard and turn on the RGB led and get various colors as well.

I have modified the rc.local file to get keyboard lights on get the internal swap working and to stop the wlan number incremental. See here.

Code:

#!/bin/sh -e
hwclock -u -s
loadkeys /lib/udev/keymaps/nokia-n900-keys.map
ifconfig wlan16 hw ether 00:1f:df:89:02:89
echo "120" > /sys/class/leds/lp5523:channel0/brightness
echo "120" > /sys/class/leds/lp5523:channel1/brightness
echo "120" > /sys/class/leds/lp5523:channel2/brightness
echo "120" > /sys/class/leds/lp5523:channel3/brightness
echo "120" > /sys/class/leds/lp5523:channel7/brightness
echo "120" > /sys/class/leds/lp5523:channel8/brightness
exit 0

I've found a charging script which seems to be working: link (I am not responsible if something goes wrong. Do not use this unless you now what are you doing.)
I've installed i2c-tools, libi2c-dev and python-smbus.

Code:

i2cset -y -m 0x77 2 0x6b 0x04 0xc9;
status=$(i2cget -y 2 0x6b 0x00)
echo status=$status

# next register 0x03 is device ID, always 4b and r/o; so we skip to 0x04
i2cset -y -m 0xff 2 0x6b 0x02 0x8c;
# 0x8c = 3v5 + .640 + .040 + .020 = 4V200, BE CAREFUL and DON'T CHANGE
# unless you know what you're doing. 4V2 is ABS MAX!
i2cset -y -m 0xff 2 0x6b 0x01 0xc8;
i2cset -y -m 0xc0 2 0x6b 0x00 0x00;

# tickle watchdog, while status indicates 'charging from wallcharger'
#while [ $(i2cget -y 2 0x6b 0x00) = 0x90 ] ; do
while [ $(i2cget -y 2 0x6b 0x00) = 0x10 ] ; do
	echo charging...
	sleep 28;
	# reset watchdog timer:
	i2cset -y -m 0x80 2 0x6b 0x00 0x80
done
echo "charging finished, status(reg0)=$(i2cget -y 2 0x6b 0x00)"

Charging seems to be working as my script show the increase of the voltage and the percentage as well.

I installed lubuntu with all it's default packages and it runs amazingly fast, but I couldn't get the DSP to work for faster video playback.

I followed along the instructions from shr,
http://shr-project.org/trac/wiki/Dev...tallGuide#DSPs

I don't know what's wrong, here is what I did:

copy over dsp libs from maemo
modprobe bridgedriver base_img=/lib/dsp/baseimage.dof
installed libgstreamer-plugins-base0.10-dev
I compiled gst-dsp on the device from
http://code.google.com/p/gst-dsp/
then copy the resulting libgstdsp.so /usr/lib/gstreamer-0.10/

then tried to play videos with gst-launch-0.10, the performance is actually much worse than just using gnomemplayer, which means the dsp isn't being used.

does anybody know what's required to correctly use the dsp ?

thanks !

No Idea, but since it is a Kernel from Meego I'd look there: http://wiki.meego.com/ARM/N900/Tips_and_Tricks/DSP Doesn't ubuntu have something in it's repositories?

it works fine now, the problem was with the way the file was played.
I originally used
gst-launch-0.10 -v playbin2 uri=file://<file>

the video plays full speed with no audio when using
gst-launch-0.10 filesrc location=<file> ! <demux> ! queue ! dspvdec ! omapfbsink
as stated on meego wiki.

I will search for a way to get playback with sound.

It could be that framebuffer memory is too low for HW resizer to work with xvimagesink, so it falls back to SW resizer (videoscale). Try to increase VRAM in kernel paramters, right now KP50 uses CONFIG_OMAP2_DSS_VRAM_SIZE=8, which allows HW down-scaling of videos upto 1280x720.

Also you may give the logs to see what is the pipeline for playbin2. And you may try to pass flags=103 to playbin2 (allow only native resolutions)

EDIT:

also you could pass parameters to playbin2, which decoder and which videosink to use
