Good day I've used Ubuntu for quite some time (years), following upgrade cycles on 32-bit and staying clear of 64-bit just because a lot of people have reported having a hard time of it. I recently installed 64-bit Jaunty on my laptop (HP Pavillion dv9352 with NVIDIA 7600 go graphics) and it worked so swimmingly that I decided to finally do a clean 64-bit install on my desktop instead of just dist-upgrade'ing to Jaunty as I would have normally done.
Things have been good for a while -- but the problems have started as soon as I've required 3D applications to work. It started when I switched from "Blank Screen" to the "BlinkBox" screensaver. I came back to my machine to find it locked up after a while. This process was repeatable. Suspecting gnome-screensaver, I uninstalled and installed xscreensaver instead -- no change. And other 3D screensavers (like Bouncing Cow) cause the same issue. When I was playin Diablo II via WINE last night, I got a lockup after about 20 min play. All system temps are well within normal operating ranges -- the hardware doesn't seem to be the problem. <ALT>-<SYSRQ> keys still work, so the kernel is still alive. Suspecting graphics, I've downgraded from the 180 driver to the 173 -- same effect. The older 96 (iirc) driver doesn't seem to allow compiz, but does seem to suck just as much -- glxgears brought the system to a standstill, with occassional response from the mouse cursor -- but nothing else. I must also note here that glxgears quite reliably reproduces the system lockup for the 173 and 180 drivers. My next recourse is to try the beta (185) drivers from NVIDIA. I would have already but the download I left going overnight apparently broke somehow: the installer is complaining about a checksum mismatch -- so I'm re-downloading. What I want to know is: is this common for 64-bit systems (to have dodgy proprietary (ie, NVIDIA / ATI) drivers)? I've seen a lot of posts online about similar issues but they range right from Warty days -- has this always been an issue? Should I have rather just stuck with 32-bit? And does anyone know of aything other than trying the beta drivers which I can give a bash? I'm not a hectic gamer, but I do like to play something now and then (doom, quake, diablo, serious sam, etc), and it sucks that I'm unable to use a simple GL screensaver. Any ideas are appreciated. -d -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Truth doesn't cease to be just because you don't agree with it.
