mouse curser disappears

mouse curser will disappear on my main monitor when coming out of sleep or if i get many things going on. have to reboot to get it back.

What video card you have? And what driver is in use?
You can choose "Default" theme for cursor in Settings -> Mouse. The Pearl theme may work buggy with few drivers.

i have nvidia quadro onboard asus M2NBP-VM CSM motherboard.
NVIDIA Quadro® NVS 210S+NVIDIA nForce®

its not the proprietary driver.
its one that someone recommended on the reaper forum.
nouveau drivers i think.
