Hi Erwin, Afaik nouveau is supported on your hardware, thus please feel free to open a bug report [1]. As otherwise your email may/will get lost in the ML Please note that resolving it may take some time due to shortage of manpower In your case something wrong is happening in the TMDS initialization script thus your blank display Can you append "drm.debug=0x2 log_buf_len=1M" to your kernel command line and attach to your bug report 1. Your dmesg output 2. Your vbios [2] Thanks Emil [1] http://nouveau.freedesktop.org/wiki/Bugs [2] http://nouveau.freedesktop.org/wiki/DumpingVideoBios > > Thanks >

It appears that this bug report has laid dormant for quite a while. Sorry we haven't gotten to it. Since we fix bugs all the time, chances are pretty good that your issue has been fixed with the latest software. Please give it a shot. (Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git versions.) If upgrading to the latest isn't an option for you, your distro's bugzilla is probably the right destination for your bug report. In an effort to clean up our bug list, we're pre-emptively closing all bugs that haven't seen updates since 2011. If the original issue remains, please make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/ for what we need to see, and re-open this one. Thanks, The Nouveau Team
