laggy mouse in games ubuntu lucid
 
hi all, first post here so be nice :D

i have a geforce 8600m gfx card with the 256.35 drivers. running kubuntu lucid with intel dual core.

any game that i try has a mouse lagging issue:

every 10-20 seconds the mouse will start lagging severely with delays around 600 milliseconds between updates. the game's framerate however does not drop. I am using a synaptic touchpad -- i have tried disabling the driver in xorg.conf but to no avail. Any workarounds possible or must i wait and hope that nvidia will fix it?

thnks!

I've seen bugs like this; they are game specific, not operating system or graphics driver related.

Would you mind disclosing which game you are having problems with?

nexuiz,sauerbraten, boswars,"battle tanks" (stupid little 2d tank killing thing) and AssaultCube. basicly every game ive tried....

Nexuiz i play in glx mode (not sdl) due to a bug in sdl that causes my mouse to not work randomly. sauerbraten/assaultcube are sdl, not sure about the rest.

ok, a little more info:

Xorg uses 100% CPU when the lagging occurs. It also seems that moving the mouse does not trigger it -- just playing the games. behaves perfectly normal in my DE.

ok more info:

I have a dual core btw, so 100% CPU is only one core.
also, i killed plasma-desktop and the Xorg spikes went away but the games are still laggy feeling (the fps is at 60). I was looking through my nvidia settings and i have digital viberence on -- maybe this could be the problem. going to try later.

turning off digital viberance didnt fix it. im out of ideas.

think i fixed it, i had an activity in kde with a slideshow for a wallpaper, and set it to change every 59 seconds. every time a wallpaper changes x uses a lot of cpu for a nice fade effect, so that was what was causing the mouse lagging. sorry to bother you all. :headexplode:
