My problem involves the Gnome-screensaver in Xubuntu and 3D rendering (and the lack thereof). Xubuntu Hardy works on another machine (P4 1,7GHz, 512MB RAM, an old Nvidia card) with no screensaver/3D problems after installing the restricted driver. This troubled machine is even older, P3 Celeron 800 MHz, 320 MB RAM and an Intel 82815 card. The display shouldn't be to blame, as I have two identical 17" screens and have tried the P3 on both. Can it be up to the ancient processor that I can't have those 3D screensavers working, as RAM shouldn't be an issue (the P4 ran those screensavers even w/ 256 MB). Or does the problem lie with the integrated Intel video card? It looks to an untrained eye that the required x.org packages for my i815 chipset are installed, i.e. xserver-xorg-video-i810 & -video-intel.
I've tried (with no change whatsoever in behavior) to remove gnome-screensaver (even purge it), reinstall it as well as install the xscreensaver package as an alternative. This is not a matter of life and death, but I'd like to know what lies at the core of this problem. Besides, I'd like to have a few games like Emilia Pinball w/ 3d on the P3 machine. Nothing ambitious, for sure. I don't intend to enable (or need, for that matter) Compiz or anything. Just to keep this humming Celeron buddy in tune and not moping in the dark.
Of the default screensavers, the following work: Deco, Distort, Fiberlamp, Floating Ubuntu, Floating Feet, Fuzzy Flakes, Galaxy, MetaBalls, Penrose, Ripples, Shade Bobs, SlideScreen, Sonar, Swirl, Universe, Xlyap and the Pictures folder. I know that's more than a few to choose from, but I wonder if the rest could be working too.
Here's my glxinfo as illustration. It's mainly gibberish to me, but isn't 3D rendering supposedly working there? If something's missing or amiss, I'd appreciate you pointing me in the right direction. I can provide more info too, so long as I know where to look and what to type.
