I believe that is the cause of this error: [ 254.402384] nouveau E[ PGRAPH][0000:f0:10.0] ERROR nsource: DATA_ERROR nstatus: BAD_ARGUMENT [ 254.402411] nouveau E[ PGRAPH][0000:f0:10.0] ch 3 [gnome-shell[2575]] subc 7 class 0x0697 mthd 0x0208 data 0x04060348 These should be "harmless" though (in that they'll just cause rendering to fail, not apps to crash). You can grab the patches at <a href="http://lists.freedesktop.org/archives/nouveau/2013-October/014671.html">http://lists.freedesktop.org/archives/nouveau/2013-October/014671.html</a> <a href="http://lists.freedesktop.org/archives/nouveau/2013-October/014672.html">http://lists.freedesktop.org/archives/nouveau/2013-October/014672.html</a> They should apply on top of mesa-git. Also, you didn't mention what version of mesa you're using, but there's a nv30/40-specific bug in the 9.2.0 release which is known to be triggered by gnome-shell. It is already fixed in mesa-git on both master and the 9.2 branches. However this: [ 258.941658] gnome-shell[2575]: unhandled signal 11 at 00000000 nip 0be2f384 lr 0be2f2d8 code 30001 appears to be a bug in gnome-shell (or one of its libraries... so I guess it's possible it's in mesa/nouveau as well). Perhaps run it in gdb and look at the backtrace? Or maybe it indicates some trouble in its stdout/stderr, not sure where that goes in your setup.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
