In the current X, if Xinerama is enabled, GNOME apps hang (gnomecc, evolution, etc), and kde3 hangs kicker & konqueror (possibly more). Disabling Xinerama makes everything happy and work just fine. This was tested with the shipping mga drivers and also the Matrox proprietary drivers & hal. No difference at all was noted.
I'll be glad to provide whatever troubleshooting legwork is requested. Can anyone else with a G450 confirm this? -- Brad Felmey
