oh fuck the new version of Xorg is completely fucking broken — there’s something fucked up with hald or the xf86-input-mouse driver or something diddling up in the old USB stack. At times the screen will just stop being fucking drawn until I move the mouse.

• Whenever I do a scroll the scrollwheel a single notch, the entire thing freezes until the next mouse event.
• Double clicking doesn’t fucking work most of the time (freezes screen until next mouse event).

Fucking balls this is gay.

UPDATE: Recompiled x11-servers/xorg-server with WITHOUT_HAL (uncheck option in `make config`), then added

Option "AllowEmptyInput" "off"

To the ServerFlags stanza, and now everything seems to be back to normal, hooray.
