Which log file shall I check?

Hi folks,

Ubuntu 1010 desktop 64 bit running on VM of VBox

On login as user a warning popup and disappeared promptly. I was not able to read it.

On;

$ ls /var/log/

alternatives.log  dmesg.2.gz      messages.1
apparmor          dmesg.3.gz      messages.2.gz
apt               dmesg.4.gz      news
aptitude          dpkg.log        pm-powersave.log
auth.log          faillog         pycentral.log
auth.log.1        fontconfig.log  samba
auth.log.2.gz     fsck            speech-dispatcher
boot              gdm             syslog
boot.log          installer       syslog.1
bootstrap.log     jockey.log      syslog.2.gz
btmp              jockey.log.1    udev

daemon.log.1      lastlog         user.log.1
daemon.log.2.gz   lpr.log         user.log.2.gz
debug             lpr.log.1       vboxadd-install.log
debug.1           lpr.log.2.gz    vboxadd-install-x11.log
debug.2.gz        mail.err        VBoxGuestAdditions.log
dist-upgrade      mail.info       VBoxGuestAdditions-uninstall.log
dmesg             mail.log        wtmp
dmesg.0           mail.warn       Xorg.0.log
dmesg.1.gz        messages        Xorg.0.log.old

Please advise on which log file I can find that warning? TIA

Hi, satimis
Apart from the VBox logs, you should, as you may know, try something like
$ tail -200 /var/log/syslog | less
or
$ tail -200 /var/log/auth.log | less
or
$ tail /var/log/Xorg.0.log | less
or
$ dmesg | less

Of course, on a VM, you may have to check both the client and host logs to get info on some problems.

I can't help you being specific about VBox (I don't know/use it)

But can you say if the VM boot and stays running even if you are not able to log? or it crash/exit? It may help to identify the problem.
There may be some VBox tools to help you debug the problem. Or a VM text console, or a remote log with terminal,...

I'm pretty sure this will not help you much, but, just in case...

Luis
