[Klug-general] Graphics card glitches

[Michael E. Rentell]

G'mornin' all,

Two or three years ago our illustrious colleague from Indie IT in 
Birchington provided me with a bespoke sooper dooper desktop compooter 
which has served me very well and still does. About a month ago the 
graphics card blew (NVIDIA 256Mb - make unknown).

I replaced it with a boxed inno3D 512 Mb card which claimed to be nvidia 
authorised GeForce 9400. My version of Linux is PCLinuxOS 2010 (32-bit) 
This is essentially Mandriva for dummies but improved by Synaptic. It 
has recognised this card as NVIDIA 'cards not working with nv'.

It seems to function reasonably well but occasionally the screen goes 
black for about 3 seconds. It then recovers and is fine. This happens 
more frequently with graphically intense programs like 
GoogleEarth/Streetview or Stellarium etc. I wondered if this was a 
driver problem. However, I also have a Vista 64-bit (sorry!) on another 
partition and I have installed the windoze drivers which came with the 
card. Same problem.

Any ideas? Thanks be to all.
