xfce4-battery-plugin currently displays the % of the battery, but it doesn't show the time (or does it need a while to figure out how much time is left?)

I did do a sudo poweroff when power was below 5%. When it first powered down, I connected the AC and restarted. The plugin immediately powered down again, as it didn't know AC was connected. |

52 | Core | Bug Report | Medium | X11-Touchscreen: Fullscreen-Issue when the mouse cursor ... | Closed | |
Task Description
There are some issues with the touchscreen using X11 and fullscreen apps which use their own mouse cursor.
The mouse cursor tends to shift around when it comes outside of the normal screen area.
This can be seen with SuperTux: The mouse cursor is a penguin. Move that close to the edge of the screen and it jumps around and then is shifted to the real touchscreen.
Thanks to a bug in SuperTux, this can also be fixed: Go into the Level Editor and go back into the main menu:
On top of the penguin mouse cursor is the normal X mouse cursor, which will not Shift anymore.
Aditionally, I tried the Hatari Menu (running on 640x480) and AlephOne (running on 800x480).
Both use the standard X mouse cursor and both are working fine.
I guess that the mouse cursor gets confused if it has negative values. |

31 | Core | Bug Report | High | X11 Crashing with omapfb | Closed | |
Task Description
Cleaned up a bit.
* Mouse is inverted if you run SDL Games from the console.
* Mouse is not properly calibrated when you run SDL Games under X fullscreen. Fixed with notaz patch that also fixes the X11-Crash with omapfb (see below)
Regarding the X11-Crash when using SDL-Fullscreen-Apps together with omapfb:
notaz nailed down the problem: It's actually xf86-input-tslib's fault-
omapfb only acted as catalizator here, causing SDL to use different code path and call different X functions.
His patch also almost increases the touchscreen problem (see above): It runs perfect for games in 800x480.
However, on small issue is left on apps with lower resolution which use their own mouse cursor:
As soon as you move the mouse outside of the game resolution (i.e. SuperTux runs 640x480), the mouse cursor stops at the end of the virtual screen and you have an offset.
This only seems to happen when the game uses it's own mouse cursor. If you go to the level editor of SuperTux and leave, the normal X cursor appears and the problem doesn't occur anymore.
So this is probably something that needs to be fixed in the game, not in the driver.
A compiled version (for testing):
http://notaz.gp2x.de/tmp/tslib_drv.so --- needs to be copied here: /usr/lib/xorg/modules/input/tslib_drv.so |

Task Description
I noticed that when I tried Quake 3 a while back that I would lose my internet connection. Only the very first time I tried it did it ever find a couple thousand servers and let me join a map. Since then, it always dies and I never see any servers.
I wasn't too concerned yet because maybe it's just Q3 doing something but tonight mplayer was running full screen and then suddenly it started chugging and the network manager popped up that it was trying to connect (spinning logo at the bottom). Since you only get one shot at network manager per boot, it was a lost cause.
The correlation I make here was that I'm sure the CPU was under heavy load for both cases but I haven't tried other programs to see what happens. I didn't have any games on this card tonight. Can anyone repeat this problem or is it a known issue? |

Task Description
The next kernel offers switching between a joystick / keyboard mode.
In joystick mode, the DPAD and ABXYRL Buttons behave like a joystick buttons and have no keyboard mappings.
In keyboard mode, the DPAD and ABXYRL Buttons have keyboard mappings and are NOT registered as joystick.
The normal keyboard keys are not affected by this.
PXML needs to have a switch added for that and pnd_run should change the mode according to that switch.
When the PND app has quit, it should always go back to keyboard mode.
The commands are the following:
echo 1 > /proc/pandora/game_button_mode # keyboard mode
echo 2 > /proc/pandora/game_button_mode # gamepad mode |

Switching between DPAD and keyboard does increase CPU usage on X A LOT. It even tends to crash ALSA if done too extensive.
According to notaz, this is due to some very old crap that's still included in X.
Internally it has one mouse and one keyboard, everything else is copied every time you press a key and bunch of callbacks are called, messages are sent to all screens and windows.
New tests from EvilDragon:
Disabling xfwm4 makes things better (ALSA won't crash anymore), but it still lags. Running it in minimal X (directly from .xinitrc) strangely fixes this - X won't eat up more than 17% CPU,
regardless how many buttons you press.
OLD Entry:
The qwerty controls when pressed are causing the system to slowdown making the application running to pause/delay. Ive seen in a least 2 application glquake and supertux. For example pressing space would cause the hiccups and shortly after the pressing stopped the application would regain normal running speed. The other joystick/nub controls work fine. glquake is getting controls direct from the event files. Supertux is using the SDL layer.
This was done on angstrom image from dec 19th.
EDIT: More tests done by EvilDragon with the latest image (pandora-xfce-image-omap3-pandora-20100102-new-kernel-fn-n-m-support.tar.bz2)
When you play with the DPAD and press a keyboard button, the app is making the small pause. You can press as many keyboard buttons as you want after that, there won't be another pause.
BUT as soon as you press the DPAD again, it pauses again. Then the next pause does happen when you press a keyboard button, etc.
So it feels like it pauses when you switch between DPAD and keyboard.
The most important thing: This only happens when you run SDL Games from X. It doesn't occur when running SDL games from the console. |

Task Description
My current configuration is:
Rootfs on first SD Card, 2nd partition.
If I put my WIZ SD Card with tons of files into the second SD Slot while booting, pndnotifyd eats up about 95% of CPU time.
After about 8 - 9 minutes, it stopped eating the CPU and the system is working normally.
This doesn't happen when I put in the card when XFCE4 is already running.
Using LSOF, I can confirm it's crawling where it shouldn't:
pndnotify 1825 root 6r DIR 179,9 1441792 62488 /media/mmcblk1p1/roms/c64/Tapes
Could it be that on first initialization it hasn't loaded the config and crawls through the whole SD Card?
On a side note: I got 44700 files on that SD Card... so if it needs about 8 minutes, that does mean it can do over 5000 files a minute! |

I'm replying in-forum:
An interesting point -- opening the lid turning the screen on, but you're still in lower power mode. The question then becomes --
Since you enabled low power mode (using the power switch), thats the logical way to un-low power mode.
Two outcomes come to mind ..
When opening the lid, one of:
i) wake up from low power mode, or
ii) Don't turn the screen on when in low power mode
(or a variation of (ii) -- flash a warning "hey, I'm in lower power, bugger off, and hit the power switch")
I can code something in; probably occured due to in my prototype, I broke the power switch, so I didn't use low power mode near the end ;) |

73 | Base OS | Feature Request | Medium | Nub: Change mouse speed, fix scrolling and add mouse bu ... | Closed | |
Task Description
Currently the nubs can be set to three different modes:
mouse, scroll and absolute
Mode 1 (mouse) works fine, but the speed is a bit slow.
Mode 2 (scroll) has inverted scrolling and it would be nice if scrolling speed would change according to how far you move it
Aditionally, I would suggest adding another mode: mbuttons (Mouse buttons).
At the moment, you can use the nubs as mouse but don't have any mouse buttons.
I think it would be very convenient if you could set the nubs as mouse buttons:
Move the nub left for left click, right for right click, up for double click and down for middle click.
That way, each user could use the left nub for mouse and the right nub for mouse buttons or vice versa. |

56 | Core | Bug Report | Medium | Movie Playing (Totem, VLC and MPlayer) | Closed | |
Task Description
Not really a bug report, just an information what issues what player has (tested using image from Feb 22nd).
MPlayer is missing a library in this image:
libxxf86dga1
Installing that one manually does make it work.
* VLC:
Plays things, but switching to fullscreen and back causes VLC to start having issues.
I wouldn't recomment VLC.
* Totem:
Works well (fullspeed video playing) when you disable the sidebar.
With the sidebar enabled, it doesn't play videos in fullscreen.
Menus are behind the video overlay as well as the controls in fullscreen mode (which is a bummer).
Needs about 10% more for the same movie than MPlayer (and therefore, stutters more often when mmcqd eats up CPU power)
* MPlayer:
Works well (fullspeed video playing) when video out is set to XV.
Audio out needs to be set to OSS. If set to Alsa, it segfaults when scrubbing around or doing a fast forward (see segfault below).
Runs very well in fullscreen, including controls on the bottom.
Does have issues displaying videos in windows (usually shows black, unless you resize the window).
Cache should be set to 40000. This will almost remove the stuttering when mmcqd accesses the SD card.
Menu is behind the video stream as well.
Only bad thing about Gnome MPlayer is, that you can't run it in fullscreen automatically when a video is loaded.
So basically, MPlayer is the best we have at the moment.
Fullscreen is really working flawlessly. Maybe we could change Gnome MPlayer to some fullscreen GUI (like the MPlayer for the Wii, etc.).
For a first release, it already works well enough.
Just need to make sure we include default settings as described above (most important: OSS sound!)
In case anyone wants to debug, here is the segfault that happens when using ALSA and fast forwarding:

33 | Core | Bug Report | Low | mmcqd eating lots of CPU power when writing | Closed | |
Task Description
EDIT:
Tried a remount with noatime and this seemed to work very well. CPU usage when writing still goes higher, but not as high as before.
Very common problem, seems to happen on all systems (just do a google search for mmcqd).
Just run SuperTux, wait about 10 seconds at the title screen and it will hang for a few seconds (while mmcqd goes up).
Same problem as on the GP2X where we also had hangs occuring.
I wonder if there's something that can be done here?
Some suggest to change mmcqd priority. Some other sites do try to remove features of mmcqd.
Another option is to mount async (like on the gp2x).
As the Pandora usually isn't switched off the hard way but should be shutdown properly, this could be a good solution.
That would mean that our suspend mode needs to call sync before shutting down.
Maybe pnd_run.sh could also run sync after a game quit?
Here are some interesting reads that might help us:
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg16345.html : "wait_for_completion is blocking call. Please check 'omap_mmc_request'"
http://www.mail-archive.com/davinci-linux-open-source@linux.davincidsp.com/msg08732.html - He disables some stuff in mmcqd which lowers CPU usage. |
