[Libdlo] 1. udlfb doesn't choose 1920x1200 and 2. mplayer shows no video on framebuffer

[Thomas Siedlich]

Hi!

Kernel: Linux 2.6.39.1 - vanilla
OS: Debian squeeze but tested with testing, too

I have a HIS Multi-View II Adapter with a EIZO FlexScan S2431W monitor connected, which has a native resolution of 1920 x 1200.

Syslog shows during connecting:

------------------------------>8----------------------------------

I get a green window of 1600x1200 so I think the device is working.

You can see in syslog that 1920x1200 is a valid mode. But why chooses udlfb 1600x1200 instead?


The next problem is:
I tried to use the 1600x1200 framebuffer with mplayer:
mplayer -vo fbdev:/dev/fb1 Sintel.2010.Theora-VODO.mp4

mplayer plays the video (better: I see status messages and hear the audio) but nothing happens on the framebuffer. It stays green.

syslog:
--------------------------8<----------------------------------

Jun 20 22:05:10 hawk kernel: udlfb: released /dev/fb1 user=1 count=0
-------------------------->8----------------------------------


I think I should fix theese two issues first before I try to use X on the framebuffer but how?

Do you have an idea what can be wrong?

Thanks.
