Yes, I have well working backspace by using fvwm. I've tried XFCE as well, that has backspace also.

It was interesting that xfce's battery monitor reports some percentage value, just needs to look a bit closer if it is real or not...

Mesa update breaks ti-omap3-sgx-bin and vice versa. Working on it.

Re: Arch Linux ARM on N900
 
Here's a nice view of my setup with e17. Quite useful although it's a posed photograph as I normally use plain text mode. The xterm window shows the battery status read from UPower daemon. The shown percentages seem correct to me. In the background runs XEmacs which has a nice and simple builtin irc client btw.

As xorg runs so fine (thanks to the configuration provided in the n900-configs package) and ssh, too (turn off power saving (iwconfig wlan0 power off) when experiencing “laggy” connections), charging and bluetooth will be my next items.

You don't need to worry about charging, just plug it in and thank Pali :)

I got crashes with bluetooth, didn't spend that much time tinkering with it though. Tip: You need to set hw address for it via sysfs before loading firmware.

How can I verify that it's charging?
Älä hakkaa, what's the upower command? Just upower gives me nothing and I can't see anything useful in the man page.

Update:
Quote:
<Skry> cat /sys/class/power_supply/bq27200-0/status
<Skry> cat /sys/class/power_supply/bq24150a-0/status
One line would be
Code:
cat /sys/class/power_supply/*/status

Re: Arch Linux ARM on N900
 
It appears int_ua has some trouble with the musb modules failing at boot. Most notable effect you probably will see is the charger not getting detected. To easily check:
Code:
dmesg | grep 'usb\|isp17'
There's been some trouble before so if you see similar behavior, and if the shutdown/poweroff trick does not help, please let me know. Both of my installs are working fine, so I can't really investigate more. In case there are more people with this problem, I need to move those drivers in-kernel, which I know will solve this.

Also,
I updated ti-omap3-sgx-bin, it is in the repos and seems to work fine with the latest mesa.

Those wanting to try out the new kbd map for VT, can wget it from here.
People living in command line might be pleased to hear that there is now Alt+B,F,R,Y and previous/next VT in the volume keys. Otherwise it is pretty much the same as us layout of xkb map, so scrolling in console etc works. This is the best thing so far with this whole project, I hardly ever need to start X anymore.

Re: Arch Linux ARM on N900
 
@ int_ua, probably upower service wasn't running: systemctl start upower.service or systemctl enable upower.service will start it for a session or permanently. upower -e as shown in my screenshot will then list (enumerate) power devices and upower -i /org/freedesktop/UPower/devices/battery_bq27200_0 will show actual battery data like charging/discharging status, native path in the filesystem etc.

Interesting, there we have another link to the actual device. But either way only reads out battery status. For charging, the known failure with musb modules at first boot occurs on my setup too, but shutdown -r now does the trick. With that workaround at hand, it's a low-priority bug I'd say.

Have you succeeded with the illume profile?

You can get all the info from /sys/class/power_supply/bq27200-0/uevent too.

Well, it's mostly a big annoyance :) I rarely boot to Maemo these days so I'm not that much affected by this. It would be technically interesting to know why this happens though, and I have my suspicions about it. I heard there are similar problems with beagleboard, and apparently there's been some work upstream which I need to take a look at.

-->Charging is working fine on my device.

-->SGX
Most probably I have missed something important, but SGX does not work.. I've installed the sgx-bin and fbdev-sgx packages started the powervr service, some sgx processes are there,but just have fbdev seg fault in Xorg.log

Do you have any idea?

-->USB NIC
I've one, based on AX88178 chip, already compiled its driver on N900. I'll test it just need proper cable to be able to connect (USB NIC<-->N900).

-->Overclocking
Is that already possible in any similiar way as with kernel-power?
