"cat /proc/mtrr" shows nothing configured regardless of whether the X11 server is running. I only see a diagnostic message to the effect of the MTRR not existing when X11 exits. Possibly significant: prior 3.X kernel versions would cause the X11 server to exit with a corrupted display after about 3-5 invocations. Machine was otherwise usable, but had to reboot remotely to recover the console display. The "no MTRR" issue in 3.1-rc1 has thus far meant no display corruption on X11 server exit: have run "startx" at least 10 times since booting 3.1-rc1. -- ------------------------------------------------------------------------ Bob Tracy | "Every normal man must be tempted at times to spit rct@frus.com | upon his hands, hoist the black flag, and begin | slitting throats." -- H.L.
