This was from: lxde-x86_64-20100309.23.iso


selinux-policy-targeted-3.7.10-4.fc13.noarch
selinux-policy-3.7.10-4.fc13.noarch

lxdm-0.1.0-0.1.fc13.x86_64
lxpanel-0.5.4.1-2.fc13.x86_64

To recreate:
Boot from liveusb.

You cannot log in using lxdm, even with setenforce=0

tried root, live, liveuser, goes in a loop user<>passwword.

logged in as liveuser using telinit 3 during boot.

startx

No lxpanel. 

used lxterminal to "yum groupupdate LXDE"

lxpanel appears, along with abrt flasher.

This is the menu-cache report.
There was a lxpanel report, but problems with "debug" packages preventted backtrace being made. Best I could get is below line

Frank, one thing at a time please. The SELinux or login issues are not related to this.

For the SELinux problems, please make sure you have lxdm-0.1.1-0.1.20100303gite4f7b39.fc13 (from updates-testing) installed. If you still have problems, with this version, please reopen bug 564320 and submit the reports from sealert (not abrt!) there.

Sorry, as it's purely a live-boot not an install, thought they may be.

May have to wait for this to get into nightly build.

No selinux on this yet.
