Everything was working fine until I pulled in the latest mesa from git and recompiled. Then gnome started going only into fallback mode. In dmesg I was getting: gnome-session-c[3618]: segfault at 100010001 ip 00007f0419ae0570 sp 00007fffd3204870 error 6 in nouveau_dri.so[7f0419a64000+495000] When in fallback mode, if I ran glxinfo it would also segfault: glxinfo[3729]: segfault at 100010001 ip 00007ffe31f49570 sp 00007fff22a85df0 error 6 in nouveau_dri.so[7ffe31ecd000+495000] Going back to commit b328949a37fee7b0f68ed3e068ffc4426c083042 fixed it. I'm afraid I have no backtrace but if someone can point me to some quick instructions I should be able to try to get one in a few days. Here is what lspci says my card is: 01:00.0 VGA compatible controller: NVIDIA Corporation G86M [Quadro NVS 135M] (rev a1) I'm using a very mixed Debian testing/unstable/experimental, kernel 3.2.0-2, amd64, on a Dell Latitude D630 laptop. (BTW, nouveau works moderately well on my box. I can run Gnome 3 but the zoom animations look like crap, maybe because the card stays in low-power mode. (I used to run the nvidia blob with Compiz, and I had to deactivate power saving to get good animations then.) After about 20-30 hours of use I usually get some kind of memory corruption, or X locks up, and I have to reboot. However, the 2d acceleration rocks, much faster than the blob! Makes it worth it.) Anyway, thanks to everyone for your great work!
