dicas01Ao ligar o micro hoje obtive o seguinte erro:

xauth: file /home/cabelo/.serverauth.2265 does not exist
xauth: (stdin):2: unknown command "c89508c0dd252761ead18eedfb3c1ffe"
Fatal server error:
(EE) Cannot move old log file "/var/log/Xorg.0.log" to "/var/log/Xorg.0.log.old"
Please consult the The X.Org Foundation support 
at http://wiki.x.org
for help. 
xinit: giving up
xinit: unable to connect to x server: Connection refused
xinit: server error
xinit failed. /usr/bin/Xorg is not setuid, maybe that’s thr reason?
If so either use a display manager (strongly recommended) or adjust /etc/permissions.local

Para resolver o problema inseri o número  /boot/grub2/grub.cfg o numero 5 no final (sudo init 5), mas até agora não entendi o motivo do problema. A seguir um exemplo:

linux /boot/vmlinuz-3.11.6-4-desktop root=UUID=e0620689-7b58-4886-a267-c0e9d7414895 \
resume=/dev/disk/by-id/ata-ST9500420AS_5VJ6G26A-part5 \
splash=silent quiet showopts 5
