Glad to hear it. FWIW, I haven't noticed any loss of functionality in any programs since disabling sys_ioperm/sys_iopl. I now have them disabled even in non- hardened/gresecurity kernels as well. The remainder of this message applies to the list as a whole: I'm happy to report that the patch worked: the Intel integrated graphics drivers now work with "privileged I/O" disabled as well. In hopes that others might benefit as well, I filed a bug report at BGO: https://bugs.gentoo.org/show_bug.cgi?id=456220 >From there you can also download the patch as a single file (as opposed to the 3-part series from mailing list to which I linked in my initial post). I tested against x11-base/xorg-server-1.13.2. Instead of failing, my Xorg log now emits the harmless message during initiation: "xf86EnableIOPorts: failed to set IOPL for I/O (Function not implemented)" I don't know whether the Gentoo X maintainers will appreciate the significance, so feel free to add comments if you think it's worthwhile. Hopefully the changes will be merged upstream soon. Dave
