From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030120 Description of problem: After exiting an app (typically Gnome Terminal), there is a lowe probability of losing the mouse pointer. The mouse continues to function properly, but you can no longer tell where it is. Incidence seems to be about once every 50 or so terminal normal exits. Possible race condition exacerbated by timing differences in the Athlon architecture. Secondary confirmation from Elton Woo (see phoebe-list Feb 16 messages), who is also running an Athlon processor. Version-Release number of selected component (if applicable): How reproducible: Sometimes Steps to Reproduce: 1.Normal exit from a terminal session. Actual Results: No mouse pointer sometimes. Expected Results: Mouse pointer is always present. Additional info: Athlon 1GHz, 521MB, nVidia geForce4mx, nv X11 module, Generic PS2 scroll-mouse.
Whatever this problem is, it is extremely unlikely to have anything whatsoever to do with you both running Athlon processors. I think you are jumping to conclusions very prematurely. You did not indicate what specific version of XFree86 you are running. When filing bug reports against a beta release or rawhide, please always include the exact version-release of the software you are using. Recommendation: Upgrade your beta install to the latest rawhide packages of XFree86, the kernel and other relevant software. If the problem persists, please attach your X server log file and config file, and get others who are experiencing this problem to please do the same so that there is more information to go on.
