Description of problem: I can't login. I just get dumped back in the LXDM login screen. (Details below.) Version-Release number of selected component (if applicable): lxdm-0.4.1-6.fc20.x86_64 How reproducible: 100% Steps to Reproduce: 1. ensure .dmrc looks like: [Desktop] Session=Lubuntu 2. try to login via lxdm Actual results: - after entering password, screen goes blank (as usual) - brief delay (maybe 0.5 sec?) - I'm dumped back in the login screen Expected results: - successful login Additional info: The workaround is easy: edit .dmrc so it looks like [Desktop] Session=LXDM Alternately, delete .dmrc. Incidentally, this situation came about because I'm switching one laptop from Ubuntu to Fedora. When I installed Ubuntu (well, really, Lubuntu), it setup that .dmrc file. I should be able to port my home directory to the new OS without mysterious login failures! Also, BTW, a perfectly valid "Expected result" would be an error message along the lines of "unknown session type 'Lubuntu' in .dmrc". Even if I was blocked from logging in, at least that would tell me what the problem is and where to fix it.
Oh yeah: /var/log/lxdm.log is not terribly helpful. I'll attach it if you want, but I don't see any mention of .dmrc or "Lubuntu" there. I strace'd the lxdm-binary process to see who was reading .dmrc. Here's the relevant snippet of strace output, with PID and timestamps: 1764 16:04:15.911669 open("/home/greg/.dmrc", O_RDONLY) = 9 1764 16:04:15.911817 fstat(9, {st_mode=S_IFREG|0644, st_size=27, ...}) = 0 1764 16:04:15.911851 read(9, "\n[Desktop]\nSession=Lubuntu\n", 4096) = 27 1764 16:04:15.911885 read(9, "", 4096) = 0 1764 16:04:15.911911 close(9) = 0 1764 16:04:15.911954 open("/usr/share/xsessions/Lubuntu.desktop", O_RDONLY) = -1 ENOENT (No such file or directory) Process 1764 is lxdm-binary: $ ps -fwwp 1764 UID PID PPID C STIME TTY TIME CMD root 1764 1 0 16:03 ? 00:00:00 /usr/sbin/lxdm-binary

There is nothing we can do. It the Lubuntu guys think they need to run a custom session with the name of the distro, it will never work elsewhere.

FWIW, I *believe* this worked under Fedora 19. For a while, I was dual-booting the laptop in question into both Ubuntu 13.04 and Fedora 19, and did not see this problem. It only bit me when I wiped the disk, installed Fedora 20, and copied my old home directory back.
