There are several graphics chipsets which don't support DRI (acceleration) in 24-bit mode. ATI Rage 128 is one of them (very common in somewhat older laptops). I need to use 16-bit cause 24-bit makes the system noticeably slower.
Conversely, what would it hurt to put export XLIB_SKIP_ARGB_VISUALS=1 in the firefox start-up script? Would it change the appearance or functionality of anything in any way? -- Flash plugin problem with ARGB visuals causes crash https://launchpad.net/bugs/14911 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
