Hi,

Is there any reason to have all the lines commented in the config file 20-omapfb.conf for xorg-x11-drv-omapfb? Mind to paste what you mean exactly?

Have a look on 20-omapfb.conf file in xorg-x11-drv-omapfb: https://build.opensuse.org/package/files?package=xorg-x11-drv-omapfb&project=openSUSE%3AFactory%3AARM We have 20-omapfb.conf file: ******************************************************************************** #Section "Monitor" #Identifier "Configured Monitor" #EndSection #Section "Screen" #Identifier "Default Screen" #Device "Configured Video Device" #EndSection #Section "Device" #Identifier "Configured Video Device" #Driver "omapfb" #Option "fb" "/dev/fb0" #EndSection ******************************************************************************** All lines are useless like this, we should remove the #.

Maybe kernel driver changed and xorg driver was not updated accordingly?

Dirk, the beagleboard on your desk has a working omapfb configuration. Mind to tell me which IP it has today, so I can extract the necessary information?

It does not get an IP address atm as the ethernet is not working, but you can connect to the screen session as root@oldboy Greetings, Dirk -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

You are using tha latest git sources? If so, Ethernet is not working due to USB clocks problems.

Hrm, this is what I could find. Probably doesn't help you too much though :(. I do remember that I had omapfb working, but with occasional black screens, since it was exceeding the GPU bus bandwidth.

That is what I did (replace omapfb by fbdev driver) to get it working. I tried to patch omapfb xorg driver to reflect those changes: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blobdiff;... but no effect.

Hi Guillaume,

This was requested by the xorg maintainers when I submitted the package.

Ok. It seems we can use omapdrm (staging driver) with those tools: https://github.com/robclark/xf86-video-omap Currently with omapfb, we use thsose tools: http://cgit.pingu.fi/xf86-video-omapfb/ Guillaume

Regards,

Joop.
