The problem isn't that the hardware is old. The problem is reproducing
the issue. Unfortunately my NV18 died (currently looking to replace
it), but with a very plain WindowMaker + no weird anything setup, my
recollection is that everything worked fine. And I wasn't willing to
take the plunge and install/use gnome... perhaps I should do that next
time with a throw-away account so that I don't mess up my stuff. I
guess XFCE isn't as heavy though.

I thought I provided some advice in the bug on how to do just that.

Hi Illia,

I will send you an NV18 card of your choice if you can commit to fixing
that bug.

Unfortunately I can't make that guarantee. Especially since I've
already tried and was unable to reproduce. I do have a bid on a NV17
or NV18 card on ebay, so just don't outbid me for it :)

I have an nv 17 too (now using lxle 12.04 with nvidia last binary).

With lxde desktop, even lighter than xfce, you should be able to find out
the problems easily. Screenshots in bug 51477 .

Thank you.
