No one seems to be able to help me with this.
Mouse movement in Linux native games doesn't work. Not on my USB mouse or mousepad.
Games like Urban Terror, Warsow, Duke Nukem 3D (eduke32), Sauerbraten, etc.
Ironically, games in Wine (Team Fortress 2, Peggle Deluxe, Worms Reloaded, etc.) and JAVA (Minecraft) work great.
This is my hardware:
Intel Core2 Duo T8100 @ 2.10GHz
3 GB RAM
GeForce 8600GT 512MB (current driver 260.19.12)
Razer Salmosa
Synaptics Mousepad
I run Ubuntu 10.10. In Ubuntu 10.04, Linux native games worked.
