The system hadn't been updated for about a month. The updates included some xorg stuff and some xfce4 stuff. Today when the workstation's user logged in via gdm, she clicked the xfce4 "Migrate Config" option, something weird happened, and she ended up back on the gdm welcome screen. Now whenever she logs is via gdm, the screen immediately goes black and she is routed back to the gdm welcome screen again. When I have grsecurity enabled I get this in dmesg: Segmentation fault occurred at 000068e453633fdc in /usr/bin/Xorg[X:4777] uid/euid:0/0 gid/egid:0/0, parent /usr/sbin/gdm-binary[gdm:4775] uid/euid:0/0 gid/egid:1010/1002 She also tried skipping gdm and issuing startxfce4 manually but it fails in a similar way and displays "disconnected from session manager". I get this in Xorg.0.log: Backtrace: [ 74.799] 0: /usr/bin/X (xorg_backtrace+0x28) [0x49eeb8] [ 74.799] 1: /usr/bin/X (0x400000+0x62849) [0x462849] [ 74.799] 2: /lib/libpthread.so.0 (0x64727eac2000+0xf3f0) [0x64727ead13f0] [ 74.800] 3: /usr/lib64/xorg/modules/drivers/nv_drv.so (0x64727bed7000+0x112d0) [0x64727bee82d0] [ 74.800] 4: /usr/lib64/xorg/modules/libshadowfb.so (0x64727a682000+0x3db2) [0x64727a685db2] [ 74.800] 5: /usr/bin/X (0x400000+0x2da29) [0x42da29] [ 74.800] 6: /usr/bin/X (0x400000+0x2eda9) [0x42eda9] [ 74.800] 7: /usr/bin/X (0x400000+0x2475a) [0x42475a] [ 74.800] 8: /lib/libc.so.6 (__libc_start_main+0xe6) [0x64727dcb2ba6] [ 74.800] 9: /usr/bin/X (0x400000+0x242f9) [0x4242f9] [ 74.800] Segmentation fault at address 0x64727462bfdc [ 74.800] Fatal server error: [ 74.800] Caught signal 11 (Segmentation fault). Server aborting and when grsecurity is enabled I get this in dmesg: Segmentation fault occurred at 000064727462bfdc in /usr/bin/Xorg[X:4647] uid/euid:1003/0 gid/egid:1010/1010, parent /usr/bin/xinit[xinit:4646] uid/euid:1003/1003 gid/egid:1010/1010 I have tried disabling all security options in the kernel but I get the same results with the exception of the dmesg info. I tried re-emerging xorg-server, xf86-video-nv, xinit, and gdm. Strangely, after re-emerging xorg-server and xinit there were files to change in etc-update. I don't see how that's possible since I'm caught up with emerge -DuN world. revdep-rebuild comes up with nothing. I'm running an emerge -e world now. It's weird that the gdm welcome screen will load (which implies xorg) but nothing afterward. Any ideas? - Grant
