FAAD2 appears to not be compiled with fixed point decoding. My version of libfaad compiled with fixed point used 2-3x less cpu than the provided one. It's not enough to provide the switch to the configure script. the file libfaad/common.h has to be edited and a define uncommented. Line 68 in the v2.7 source.

/* #define USE_DOUBLE_PRECISION */

The appdata folder was corrupted on my SD card from an unclean eject this made the folder read only until i ran a repaired it. MiniMenu still displayed all my PND files.

When clicking to launch the app would try to load crash and then return to MiniMenu without any visible error. This was pretty confusing and i thought it might be a good fix for a troubleshooting guide.

Battery remaining percentage in MiniMenu does not update unless you change tabs back and forth.

This is only really an issue when leaving the unit charging and not using it. It gives the appearance that it is not charging until you swap tabs around.

Hi there,

Many games depend on sdl-perl. Perl and sdl are part of the base OS, but not not the connection between the two.

Cheers,

I added:
iface usb0 inet dhcp

And ran:
ifup usb0

But dhclient simply prints usage.

When the Pandora runs out of memory and the Out-Of-Memory killer fires, the Applications/Settings/xfce4/panel/panels.xml loses the entries for the menu button and the power monitor.

When a X window which is displaying GLES2 render output is:
- Either dragged out of the visibile screen region (?)
- Is made larger than it was at the creation time of the GLES2 context
then:
- The performance will drop significantly as the EGL buffer swaps won't occur as fast as before,
- The render output will be corrupted and flicker
- In rare occasions crashes the application or locks up the entire system (which forces you to remove the battery)

The problem can not be solved without restarting the application (Possibly forcing players to complete the same goals again as they were unable to reach a savepoint or similar things).

This was confirmed in Mupen64Plus and the PowerVR GLES Samples and some of my own projects (which are, however, based on the PowerVR samples).
As I didn't see any other reports about this problems (but had it confirmed by other Pandora users too) I would expect that it can be fixed by using a newer X, kernel or combination of them as other OMAP users would be effected too.

When I have received my Pandora, I got an SD Card but it was not formated. I didn't have any card reader so I didn't now what was wrong (the Pandora or the SD Card).

When an unformated SD Card is inserted in the Pandora, it should be nice to ask if we want to format it.

On OS Zaxon (hotfix 3).

With "xfconf-query", the resolution is 800x480@60 Hz.
But with the tool in the menu "Settings" -> "Display", the resolution is 800x480@0 Hz.

With Java (opensdk-6-jre 6b18-1.8),

GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice().getDisplayModes()

return 1 display mode that is 800x480@0 Hz with a BPP of -1.

It seems to be the reason that GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice().getDisplayMode() return null
and when closing a java application that goes in fullscreen mode to throw an exception (invalid display mode).

With both Hotfix 3 and Hotfix 4 Beta the Run PND Application menu item fails to do anything.

Possibly related problem is that PND files newly copied to SD card are not recognized and entered on desktop as expected.
When you go to Thunar and right click - execute the PND file, nothing happens.
Possible fix by copying the PND to another folder on the SD card with Thunar.
This makes at least two PND files I had work.

Still no response with "Run PND Application" menu, though.

When booting the pandora-OS from sd-card by using the official tar, you will end up with your sd-card being mounted twice: once as / and once as /media/<label>. I solved this by adding "/dev/mmcblk0" to "/etc/udev/mount.blacklist". Maybe this should be added to the default tarball? I'm not sure as it might be used in other ways maybe (beside SD-card-installation)?

Background: I ran "updatedb" as root and have been notified by a message that there was a mount-loop. After adding the above modification the system still booted fine and "updatedb" ran nicely without a warning.

I am running PandoraOS from sd-card installed with the official tarball "pandora-rootfs.tar.bz2".

I noticed that the control/keyboard-mapping in vi does not work correctly after switching to root (for example sudo su-). I solved this by copying over my users .vimrc to root-homedir. This should already be included in the tarball.

The patch implementing screen blanking uses the /usr/pandora/scripts/op_lid.sh script to control LCD backlit:
http://git.openpandora.org/cgi-bin/gitweb.cgi?p=openembedded.git;a=blob;f=recipes/xorg-driver/xf86-video-omapfb/pandora_backlight_dim.patch;h=4a0b8432d083c6e7297192a2920c7a777ae3d098;hb=16f3fff44323bd6b4349d909667b51a2fef3f278

The same result can be achieved by using the sys interface:
/sys/devices/platform/twl4030-pwm0-bl/backlight/twl4030-pwm0-bl/bl_power

This approach makes driver independent on particular distribution. The proposed patch is attached.

Try clearing shortcuts in Start->Settings->Window Manager->Keyboard. That doesn't work (for me).
This is a problem because these shortcuts are blocking key-combination in apps, like for example the keymapper in dosbox (CTRL+F1) or refreshing content (CTRL+F5). I tried manual editing or even deleting the configuration file, but changes are not recognized and the file recreated on reboot.

Ok, I just want to say that there is something missing about the font on the base image. I cant get what (at least for now)

Here is an issue : http://www.gp32x.com/board/index.php?/topic/54282-getting-vnc-viewer-to-work/

With my current Ogre build I get :
Warning: Unable to load any usable ISO8859 font
Error: Aborting: no font found

I've googled but so far no solution :(

That still need to be configurable, but chris_c does a good job I'ld like to see integraded in the main image :
http://www.gp32x.com/board/index.php?/topic/58794-a-script-to-shutdown-after-charging/
and :
http://chrisc.bedroomcoders.co.uk/?p=77

http://trac.wader-project.org
http://trac.wader-project.org/wiki/Developers

this would be really usefull to monitor reception/network of mobile broadband dongle and it also counts ur mobile data usage (for those that have limits).

It'll have to be in the SKEL.
/etc/skel/Applications/Settings/Thunar/uca.xml

People can replace the contents of their current uca.xml file with the following to gain this functionality now.

Zaxxon Hotfix 5.

Example (dropbear is running):

------------------------
~# nc -vvvv localhost 22
Notice: Real hostname for localhost [127.0.0.1] is localhost.localdomain
Total received bytes: 0
Total sent bytes: 0

~# telnet localhost 22
SSH-2.0-dropbear_0.51
------------------------

All required libraries seem present, strace output is inconclusive.

Problem - Login Screen does not accept all symbols of the form Fn+char
Reproducibility - always
Actual results - the characters :?#|$€"‘£¥@!_ do not work on the Login Screen with the Pandora's keyboard. When fn then the corresponding character is pressed, nothing is added to the string.
Expected results - these characters should appear just like any other character
Work Around - an external keyboard was able to enter these characters
Aditional Information - While the characters :?#|$€"‘£¥@!_ do not work, the characters ;/\'-+=`() work just fine.

opengles and op_power.sh don't like each other very much.
whenever returning from low power to full power mode again, opengles rendering is just dead.

the reason for this issue are following 2 lines within op_power.sh

18 echo 0 > /sys/devices/platform/omapfb/graphics/fb0/blank
...
66 echo 1 > /sys/devices/platform/omapfb/graphics/fb0/blank

if these lines are removed/commented, the gles rendering just resumes fine.

using evdev xorg drivers and not the tslib drivers you can receive pressure axis data however there is
a problem with the values reported by the ads7846 module and the evdev driver has no calibration property for pressure

using
xinput test touchscreen
you can see the pressure axis ranging from 120-ish for hard press to about 150-170 for light press (low pressure values can
be quite erratic)

I could possibly hack the evdev module to possibly do something with this odd and narrow range of values, but I rather think looking
at the source that the ads7846 module needs some work.

is there a git tag that has a known working configuration? as I've had problems getting the kernel to compile the last few times I attempted...

Found I'd kept some notes about making the Pandora's wake on alarm function work...

drivers/rtc/rtc-twl4030.c

twl4030_rtc_remove (for when the driver is removed) and twl4030_rtc_
shutdown (for when the system is shutdown) functions need to change. Or at least the shut down does.

oh YUK who's been using goto....

changes in drivers/rtc/rtc-twl4030.c

twl4030_rtc_remove
commented out //mask_rtc_irq_bit(BIT_RTC_INTERRUPTS_REG_IT_ALARM_M);

twl4030_rtc_shutdown
replaced
// mask_rtc_irq_bit(BIT_RTC_INTERRUPTS_REG_IT_TIMER_M |
// BIT_RTC_INTERRUPTS_REG_IT_ALARM_M);
with
mask_rtc_irq_bit(BIT_RTC_INTERRUPTS_REG_IT_TIMER_M);

twl4030_rtc_suspend
replaced
// mask_rtc_irq_bit(BIT_RTC_INTERRUPTS_REG_IT_TIMER_M |
// BIT_RTC_INTERRUPTS_REG_IT_ALARM_M);
with
mask_rtc_irq_bit(BIT_RTC_INTERRUPTS_REG_IT_TIMER_M);

twl4030_rtc_init
added (before return!)
twl4030_rtc_alarm_irq_set_state(true);

Should probably check reg 0x2B with mask 0x08 to see if alarm should be left enabled or not ?
but only in twl4030_rtc_shutdown and ?remove? NOT in twl4030_rtc_init
should remove ever happen ???

I'm guessing it's best to not enable the alarm irq's all the time???
