I confirm that after installing libdrm-2.4.18 and recompiling all the other packages like usual, it fixed the problem, thank you, it was the third update I had problem with, this one seems stable for now about a week. <div class="gmail_quote">On Mon, Mar 15, 2010 at 4:14 PM, Keith Packard <<a href="mailto:keithp@keithp.com">keithp@keithp.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div class="im">On Mon, 15 Mar 2010 15:52:41 -0400, Jérôme Poulin <<a href="https://mail.google.com/mail?view=cm&tf=0&to=jeromepoulin@gmail.com">jeromepoulin@gmail.com</a>> wrote: > #6 <signal handler called> > #7 drmmode_ConvertFromKMode (scrn=0x7f2540, kmode=0x0, mode=0x1e9c4d0) at > drmmode_display.c:240 > #8 0x00007fe72ab87427 in drmmode_output_get_modes (output=0x7f7190) at > drmmode_display.c:831 </div>That "can't" happen as drmmode_ConvertFromKMode should only be called when you actually got modes from the kernel. I'd suggest updating to libdrm 2.4.18 and then getting a more complete backtrace ("bt full") if you're still seeing crashes. -- <a href="https://mail.google.com/mail?view=cm&tf=0&to=keith.packard@intel.com">keith.packard@intel.com</a> </blockquote></div>
