Good day Thanks for your response. Suspecting that there could be a problem with the card itself (rather inconveniently coincidental, since I just bought a new mobo, psu and ram after a power surge (as far as I can ascertain) killed my PSU and I wasn't sure exactly what was dead, and just wanted to cover my bases; also, as noted in the OP, I reloaded, going from 32bit Jaunty to 64bit -- that seemed like the most likely culprit since 2D was working fine and 3D worked for a while), I bought an XFX GTX260 -- I've wanted to upgrade for the last year or so anyways... No problems now. (:
I still find it odd that 2D worked flawlessly and 3D worked for a short amount of time -- about 5 seconds for glxgears and anywhere from 5 minutes to a few hours for GL screensavers... But perhaps there was a circuit in the "3D parts" (I'm no electronic engineer!) which was damaged and just needed to warm up a little through usage to become blatantly broken. I'm going to give the card to someone else to test -- will report back. If the card works fine for someone else, then I really don't know how how to proceed with debugging this. I would have to assume that if the card isn't faulty elsewhere, then someone else may encounter the same issue. I'm still annoyed by the "nvidia flicker" on my laptop -- but apparently that's a long-standing issue (allegedly the quick black flicker is from the onboard gpu changing power usage / clock levels). To answer all posed questions (because it would be rude not to (: ). Some answers are from memory, so please bear with me: 1) glxinfo showed the usual large amount of stuff -- with the gl extensions supplied by NVIDIA 2) Yes, the NVIDIA closed driver was not only installed, but in use -- lsmod confirmed this (I also started to wonder...) 3) I did have compiz-fusion enabled. Never had the problem before, but I do believe I tried disabling compiz and still found simple apps like glxgears to cause lockup. See the wierdness? Compiz-fusion worked fine (with all its GL interaction), but something with a little more demand wreaked havoc) 4) Yes, totally up-to-date. Compulsively so (: -d On Wed, Jun 10, 2009 at 12:41 AM, Dane Mutters <dmutt...@gmail.com> wrote: > On Mon, 2009-05-25 at 07:59 +0200, Davyd McColl wrote: > > 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.
