Not sure if I am doing something wrong at all or not. But I've been trying the wheezy image from here. While I can get everything installed ok I've a problem with video acceleration.
I've managed to install the packages and have taken note of the changes here to do with installing the packages and kernel for video acceleration. But unless it is something I'm not doing right, performance dosen't exactly seem to be all that great even with acceleration.
I noticed that one thing that I could do btw to improve performance just a little was to turn down the colour depth. I did this by doing the following;
I changed the part where it says "bpp=32 to bpp=24" and this helped after running
$ mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr
To recreate the boot.scr image. This helps and it is quite noticable but I'm still finding the whole thing to be still quite sluggish. Video playback too is similarly slooow - even a simple low resolution video has problems playing either with vlc or mplayer (the best output driver I could find for video was SDL; none of the others worked except for X11 which was very, very slow indeed).
So far I've tried xfce4 and kde (which I'm using right now) though there really isn't much in terms of performance between them both. Kde 4 does have one or two nasty bugs for example with plasma applets -- the left mouse button dosen't work with them (for example, clicking on kde's usb mount icon in the system tray brings up a list of devices to mount, but you can't choose any of them! There is also a system settings problem with changing the look of the pointer as well, which just crashes) .
I'm wondering is there any way to check or accelerate 2D performance at all? I understand the accelerated X drivers work for 3D but maybe 2D isn't doing anything at all? *confused! Although dropping the colour depth down I am thinking what I am doing isn't really *properly* speeding things up!
I would try the debian jessie image though the website says that the acceleration is for wheezy only....

Hello all :-) !
Not sure if I am doing something wrong at all or not. But I've been trying the wheezy image from here. While I can get everything installed ok I've a problem with video acceleration.
