I'm running Ubuntu 10.04 with the KDE manager. To make a long story short (long story below) it now takes a long time for the KDE user login window to appear after reboot. Basically, for a minute or two I'm simply starting at the background to the usual log in window but have not place to user name, enter password, etc. My current workaround is simply to wait, but it is frustrating.

Two questions:

  • is there a quick way to bring up the login window if it's not present?
  • what can I do so I don't get this behavior?

Interestingly enough, if I log out, I do get the login window immediately. It's only after reboot that it takes a long time to appear.

(Background: why am I rebooting? I have a dual boot machine and I do need to do some things in Windows XP for my job.)

The long story is that since upgrading to 10.04 LTS -- about April, 2011 -- I sometimes get a message when rebooting that X windows has dropped into low resolution mode. I'm then presented with some choices. Usually I simply power cycle at this point. Today, I foolishly chose "reset to defaults." Fortunately I had a saved copy of /etc/X11/xorg.conf, so I overwrote the existing xorg.conf with the save copy and rebooted.

Have you checked /var/log/dmesg and the like (eg system) to see if you can see what the problem is. There's also bootchart (IIRC) that creates a graph of the boot and shows where delays are happening. It's KDM (or GDM or LightDM or whatever) that brings up the login window, you could try using one of the others to see if that makes it quicker.
