The last year, probably longer, I have been dealing with increasing stability issues that seem related to some graphics subsystem and that I can not find a clear solution to.
The problems have gotten worse over the years, are most prominent in Gnome 3 and Unity, a bit less so in KDE 4 and even less so on XFCE. Some of the problems are (non-exhaustive):
- Fullscreen video only works intermittently and mostly not. This is most pronounced with Totem but occurs with Dragon Player, MPlayer, VLC, etc etc.
- Maximizing Console windows (gnome-terminal) has a significant (say 5-6 seconds) delay
- Chrome starts heavily glitching after using it for a while
There are more smaller artifacts and I have tried researching each of them in isolation and/or combination, have ended up on epic questions and comment threads where all sorts of issues are debated in the compositing/nvidia/xorg/whatever realm. None of the approaches has been successfull for me so far.
I have reached a point where I am considering that perhaps I may be suffering from a poorly supported graphics card and the increasing use of the GPU in Linux in recent years may be making this more prominent. I have a very recent mainboard/CPU/RAM combo but have been dragging along my NVIDIA Geforce 6600 GT for a while now. Wikipedia lists it as being released in 2004, which in GPU terms is probably paleolithic.
Before I spend a not insignificant amount of money on say an NVIDIA GTX 660 I was wondering if someone can offer some insight on whether this strategy has any chance of success or whether I would be better off trying something else?
I know this question is very broad and vague and without knowing my exacty symptoms/problems it is almost impossible to answer, but perhaps having certain generations of old(er) video cards is a known problem in the Ubuntu community.
