Sorry that I cannot give more detailed summary because I don't know which package causes this. I installed kde 4.2 on my laptop. When this bug happens,every program hangs when starting. strace output like this: strace smplayer: .... connect(14, {sa_family=AF_FILE, path=@"/tmp/.ICE-unix/3622"...}, 22) = 0 fcntl64(14, F_SETFD, FD_CLOEXEC) = 0 write(14, "\0\1\0\0\0\0\0\0"..., 8) = 8 read(14,*********hang here******************* strace vi .... connect(3, {sa_family=AF_FILE, path=@"/tmp/.ICE-unix/3622"...}, 22) = 0 fcntl64(3, F_SETFD, FD_CLOEXEC) = 0 write(3, "\0\1\0\0\0\0\0\0"..., 8) = 8 read(3,**************hang here************ This _sometimes_ happens about half an hour after X starts and maybe _unproducable_ for everyone. I googled yesterday and found ubuntu has this problem too. https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/58171 since when I cannot open vi without '-X' option,this should be related to xorg-server Reproducible: Always Steps to Reproduce: 1.start kde and login 2.wait.you can do anything to kill time:-) 3.well,something happend.you found you cannot open any gui program anymore now.

Just a wild guess, but according to your "emerge --info" you're using nvidia-drivers which has some nasty bugs in version 180.35. Please have a look at bug #260441 in case you're using that version. If downgrading the driver fixes your problems, please mark this bug as duplicate of the above mentioned bug.
Re-open if appropriate.

But when I remerge the world =nvidia-drivers-180.35 was masked and I installed =nvidia-drivers-180.29.So **maybe** this is related to nvidia-drivers problem.
