Hi,
I had to reinstall the system from stage4 after a repair, on a new hard disk. First I had serious difficult to understand why at the begin the system didn't start (kernel panic - cannot open root device), at the end I discovered that I had to change the config because something had changed:
Code:
lshw before:
       *-isa
             description: ISA bridge
             product: HM65 Express Chipset Family LPC Controller
             vendor: Intel Corporation
             physical id: 1f
             bus info: pci@0000:00:1f.0
             version: 04
             width: 32 bits
             clock: 33MHz
             capabilities: isa bus_master cap_list
             configuration: latency=0
        *-storage

             vendor: Intel Corporation
             physical id: 1f.2
             bus info: pci@0000:00:1f.2
             version: 04
             width: 32 bits
             clock: 66MHz
             capabilities: storage msi pm ahci_1.0 bus_master cap_list
>>             configuration: driver=ahci latency=0
             resources: irq:41 ioport:4088(size=8) ioport:4094(size=4) ioport:4080(size=8) ioport:4090(size=4) ioport:4060(size=32) memory:d1708000-d17087ff

Code:
lshw after:
        *-isa
             description: ISA bridge
             product: HM65 Express Chipset Family LPC Controller
             vendor: Intel Corporation

             capabilities: isa bus_master cap_list

But the disk is the same (?)
Code:
     *-scsi
          physical id: 0
          logical name: scsi0
          capabilities: emulated
        *-disk
             description: ATA Disk
             product: ST320LT020-9YG14

I don't understand what changed (the cable?) and if it's better now...
EDIT: I think they changed the option in the bios, now I selected the AHCI option and is as was before... (but another "OS" didn't appreciate the switch)

But now I had problem with gdm that starts but is locked, just the waiting cursor appears. I stopped gdm and tried startx as normal user but I got the message:
Code:
xauth: file /home/<user>/.serverauth.20440 does not exist
Fatal server error: cannot move old file "/var/log/Xorg.1.log" to "/var/log/Xorg.1.log.old"
(EE)

If I exec startx as root, it starts without problem. Some info:
Code:
 $ groups <user>
wheel audio video usb users plugdev <user>

Code:
# mount
rootfs on / type rootfs (rw)
/dev/sda6 on / type ext4 (rw,noatime,data=ordered)    << no nosuid
proc on /proc type proc (rw,relatime)
tmpfs on /run type tmpfs (rw,nosuid,nodev,relatime,mode=755)

/dev/sda7 on /home type ext4 (rw,noatime)
binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,nodev,noexec,nosuid)
/dev/sda5 on /root/TMP type ext4 (rw)

Code:
 $ cat /etc/fstab
# /etc/fstab: static file system information.
# <fs>                  <mountpoint>    <type>          <opts>          <dump/pass>
/dev/sda6               /               ext4            noatime         0 1
/dev/sda7               /home           ext4            noatime         0 1

proc        /proc        proc    defaults             0 0
shm         /dev/shm     devtmpfs   nodev,nosuid,noexec  0 0

What can I check/do?

EDIT: the problem was solved removing polkit, recompiling with revdep-rebuil and recompiling xinit
