original Xomap binary does not make difference, it is the kernel (both mine and the one from jott). Just flashing kernel without rotation support restores camera and media player functionality. Looks like the kernel patch messes up something or the extra functionality confuses overlay code.

Just out of curiosity is it possible to get the required parts of the kernel compiled as a module instead of having to reflash the entire kernel?
Or is something having to be changed in the kernel that prevents this from happening, I can't say I've looked into the rotating of the screen much so I have no idea what is actually being done.

It's a shame video & camera do not work in normal mode, I would be perfectly content if it didn't only work in the rotated modes.
On a seperate note, I think its killed canola 2 too. Canola2 only shows a green screen.

Ahh ok cool makes sense now, so its actually patching the existing kernel not compiling in anything extra as such.
Cheers.

gtalk fails too. It rejects calls and disconnects right away after making connect!

Tried this yesterday and it works rather nicely, though it is by no means flawless.
I think most of the killer bugs have been mentioned already, so i shall not elaborate.
Still, rotating the screen is a very useful feature.

The kernel would and i'm pretty sure the xserver would. But you would have to use xrandr at cli to rotate screen.
I must add I do not use kde, but it's an educated guess.

I have uploaded updated kernel that seems to work with media player and camera.
http://fanoush.wz.cz/maemo/kernel-2....otation.tar.gz
Basically I reverted two changes below back to original state
While the idea in those changes looks good for normal screen, it messes up resolution of overlay/video/camera plane because it uses values from LCD panel resolution (panel->x_res,panel->y_res =800x480) which is wrong for (smaller) overlay plane.
With stock kernel after playing Nokia_N810.avi video it looks like this
With the code above in effect, resolution is changed to 800,120 which is not ideal :-)
Omitting those changes seems to not to break anything visible and allows overlay plane to work (even in rotated mode). Still, this quick 'fix' is not correct and better code is needed. Please report if this kernel makes anything worse.
