Arch Linux

whenever X is run with -sharevts in the form:

X :0 -sharevts [-novtswitch]

it runs with 100% CPU usage. the two are normally used together, however, it is linked almost solely to -sharevts this happens running stock kernels and xorg in current. it has only been tested with nvidia cards so far.

to recreate this, do the following:

at a true console (not a terminal like xterm or urxvt) type:

cp .xinitrc .xinitrc.bak
echo "exec xterm" > .xinitrc
startx -- :0 -sharevts


when X starts, and the xterm comes up, run top and look at the CPU usage for X

when done you can run:

rm .xinitrc
mv .xinitrc.bak .xinitrc

to recover your .xinitrc.
