I recently did an apt-get upgrade on my system. Sadly, this completely broke X. To fix things, I manually installed task-x-window-system-core since apt-get was holding it back. I configured the system during the set up script and X still wouldn't start claiming that the configuration files were wrong. I ran XF86Setup and reconfigured X, and though it could successfully start the X server, startx would still fail claiming that the configuration script was wrong. I then installed xserver-svga and now X starts fine. However, I'm curious if I'm running X 4 or 3.x.
dpkg claims: ii xserver-common 4.0.1-10 files and utilities common to all X servers ii xserver-common 3.3.6-18 files and utilities common to XFree86 3.x X ii xserver-svga 3.3.6-18 X server for SVGA graphics cards ii xserver-vga16 3.3.6-11 X server for VGA graphics cards ii xserver-xfree8 4.0.1-10 the XFree86 X server But I know for a fact that an unpatched XF86_SVGA for 3.3.6 doesn't work correctly with my video card (s3 savage 4) so I don't think it's using 3.3.6, but 4 seemed to fail until I installed xserver-svga 3.3.6-18. How can I tell what's running?
