A few minor issues with dual displays.
 

I have 2 monitors(and 2 display cards), and the displays themselves work fine. I am using the setup where each display is its own instance of x(I think thats how to describe it, I can't drag windows between them, but the mouse moves freely between them)

Anyways, I have a few minor issues with it. Firstly, I changed my startup runlevel to 5, so it boots up to a graphical login, and this works fine. However, the computer crashes if I use the ctrl+alt+backspace shortcut to restart X.(this worked fine when the runlevel was set to the default 3?)

Also, on my second display, I have the desktop set to align icons to the grid, problem is this doesn't work, and the icons float around wherever they want, but on the main monitor this works fine(using KDE). I also have a random issue with font sizes on the second monitor as well, most of the time they will be "regular" sized, but on occasion, when I login they are smaller(which is how I would prefer it to be, but I can't figure out anything different that changes the sizes of the fonts on each reboot, and its random as to whether or not they are the same as the last reboot)

Using slackware 11.0, running a 2.6.22-rc2 kernel.

Any help would be greatly appreciated
