Hello, I am running sid, and updated to X.org 1.20.0. Since then I cannot login.
I am running lightdm with xfce. lightdm comes up just fine, but when I login, after a second or two, it comes back to the lightdm login screen. I have an old graphics card (EVGA 6600GT) and monitor (NEC 1970GX) from 2005. They use the nouveau display driver. Has anyone else run into this problem? I am not sure if this is an xserver-xorg-core problem or an nouveau problem. The only change for nouveau that I am aware of is that xserver-xorg-video-nouveau was rebuilt against xserver 1.20. Below are the error messages that I could find. I'm not sure how to interpret the backtrace. from /home/myhome/.xsession-errors: dbus-update-activation-environment: setting XDG_DATA_DIRS=/usr/share/xfce4:/usr/local/share/:/usr/share/ /usr/bin/x-session-manager: X server already running on display :0 xfce4-session-Message: 14:51:48.954: SSH authentication agent is already running gpg-agent[1243]: WARNING: "--write-env-file" is an obsolete option - it has no effect gpg-agent: a gpg-agent is already running - not starting a new one (xfce4-session:1226): xfce4-session-WARNING **: 14:51:48.958: gpg-agent returned no PID in the variables Thunar: Cannot open display: xfwm4: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.0. xfce4-session: Fatal IO error 11 (Resource temporarily unavailable) on X server :0. from /var/log/Xorg.0.log: [ 7878.421] (EE) [ 7878.421] (EE) Backtrace: [ 7878.422] (EE) 0: /usr/lib/xorg/Xorg (xorg_backtrace+0x4d) [0x5571771ab6fd] [ 7878.422] (EE) 1: /usr/lib/xorg/Xorg (0x557176ff8000+0x1b73b9) [0x5571771af3b9] [ 7878.422] (EE) 2: /lib/x86_64-linux-gnu/libpthread.so.0 (0x7fdff8720000+0x11f50) [0x7fdff8731f50] [ 7878.422] (EE) 3: /usr/lib/xorg/Xorg (miRenderColorToPixel+0xe) [0x55717711fa9e] [ 7878.422] (EE) 4: /usr/lib/xorg/modules/libexa.so (0x7fdff5190000+0xf12b) [0x7fdff519f12b] [ 7878.422] (EE) 5: /usr/lib/xorg/Xorg (0x557176ff8000+0x13a786) [0x557177132786] [ 7878.422] (EE) 6: /usr/lib/xorg/Xorg (0x557176ff8000+0x12eaec) [0x557177126aec] [ 7878.422] (EE) 7: /usr/lib/xorg/Xorg (0x557176ff8000+0x5b008) [0x557177053008] [ 7878.422] (EE) 8: /usr/lib/xorg/Xorg (0x557176ff8000+0x5f008) [0x557177057008] [ 7878.422] (EE) 9: /lib/x86_64-linux-gnu/libc.so.6 (__libc_start_main+0xe7) [0x7fdff8381a87] [ 7878.422] (EE) 10: /usr/lib/xorg/Xorg (_start+0x2a) [0x557177040d0a] [ 7878.422] (EE) [ 7878.422] (EE) Segmentation fault at address 0x8 [ 7878.422] (EE) Fatal server error: [ 7878.422] (EE) Caught signal 11 (Segmentation fault).
