[Bug 567260] Re: xserver-xorg-video-omap* fail due to no /dev/fb
given that we only support one kind of board with the current kernel and all of these boards default to having /dev/fb0 as their default video device i think the safe quick-fix would be to just change the above DEFAULT_DEVICE definition (fb1 is used by the xv code in that driver in the same way). indeed a proper fix would be to add any kind of autodetection mechanism that checks for existence of fb0 fbdev_open() and fbdevHWInit() from xorg-server/hw/xfree86/fbdevhw/fbdevhw.c seem to provide something like that. -- xserver-xorg-video-omap* fail due to no /dev/fb https://bugs.launchpad.net/bugs/567260 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Olivier, I agree with this quick fix. I can try that on my OMAP4 board whenever you make a fix available. we can think about the right method for 10.10 -- xserver-xorg-video-omap* fail due to no /dev/fb https://bugs.launchpad.net/bugs/567260 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Attached patch is what I have been using on my omap zoom2 to solve this bug. In long term proper fb searching is probably needed. But in short term /dev/fb0 will always be the correct fb. ** Patch added: fb-search.patch http://launchpadlibrarian.net/44951669/fb-search.patch -- xserver-xorg-video-omap* fail due to no /dev/fb https://bugs.launchpad.net/bugs/567260 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I tried the patch on OMAP4 board.

[Bug 567260] Re: xserver-xorg-video-omap* fail due to no /dev/fb
The other way to solve this problem would be add a section in /etc/X11/xorg.conf.

shashi: thanks for that snippet, though note that we dont use xorg.conf by default anymore but indeed it can be used as a workaround ... the requirement for a packaged driver though is to work without the file and use the autodetection mechanisms provided by xorg. -- xserver-xorg-video-omap* fail due to no /dev/fb https://bugs.launchpad.net/bugs/567260 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
