This is a known issue: http://wiki.archlinux.org/index.php/Xorg_input_hotplugging#My_mouse_is_jerky.2Funcontrollable_in_SDL_apps.2Fgames.21_WTF.3F https://bugs.launchpad.net/ubuntu/+source/libsdl1.2/+bug/189958 http://www.gentoo-wiki.info/TIP_Activating_wheelmouse_support_in_Xorg#Uncontrollable_mouse_in_SDL_apps At least in my case,I was suffering this with enemy-territory and editting xorg.conf for adding omit xfree86-dga "solved" the issue for me What exact info do you need exactly? Thanks!
Peter, just a quick question : what kind of interactions are there between evdev and DGA? Even with newer versions of the server, mouse+DGA seems to work, while evdev+DGA goes completely haywires. Any clues? Should I just tell users to disable DGA in SDL and/or in their xorg.conf? Cheers

Put a couple of xf86Msg(X_ERROR, "..."); into xf86PostMotionEventP (hw/xfree86/common/xf86Xinput.c) to check if the data is the same. Do you see any differences there?
This is a mass change of bugs. Bugs assigned to me that haven't been updated in the last 3 years are closed as WONTFIX, because, well, let's at least be honest about it. Please do not re-open unless you have a really good reason to do so (e.g. you're fixing it yourself). If it hasn't been fixed in the last 3 years, it probably won't be fixed anytime soon either. Sorry.
