After an update LXDM gives me a black screen and I have to reboot several times for it to work. Here is my LXDM log: ** Message: 1447857384: add xserver watch X.Org X Server 1.18.0 Release Date: 2015-11-09 X Protocol Version 11, Revision 0 Build Operating System: Linux 4.2.6_1 x86_64 Current Operating System: Linux masters 4.2.6_1 #1 SMP PREEMPT Tue Nov 10 07:19:29 UTC 2015 x86_64 Kernel command line: BOOT_IMAGE=/boot/vmlinuz-4.2.6_1 root=UUID=a50727de-d384-4a4b-991a-92e83aff0ffb ro loglevel=4 Build Date: 12 November 2015 06:40:40AM Current version of pixman: 0.32.8 Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.
