From: Juha Nieminen on 15 Apr 2008 23:24 I am running Suse 10.2. I have an ATI Radeon X800 and thus I cannot use ATI's own linux driver for this reason: http://ati.cchtml.com/show_bug.cgi?id=499 (Yes, I have tried it. The X800 card runs hot like a grill with ATI's driver.) For this reason I'm using the 'radeon' device driver. Problem is: No 3D acceleration, so OpenGL programs can only run in software mode. However, that's not the major problem. The huge problem is that after running an OpenGL program a few times (usually two) the system hangs completely. (And I really mean completely: It becomes absolutely unresponsive. No keyboard lights, doesn't respond to any outside attempt at contact. It's completely hung.) The only solution is a hard reset. I can live without hardware-accelerated OpenGL (although I'm not happy with that, of course). However, any program being able to completely crash my system by simply opening some OpenGL windows is not a good thing. This is a major problem. Any suggestions?

Get an Nvidia card. For best price/perf I recommend a 7600GT. An 8600GT is too slow... anything better that's contemporary costs too much (don't need DirectX 10 in Linux). You can get a 7600GT for about $50 USD slightly used. Even less if you get a 7600GS (but it's not as fast). A 7600GT is enough to handle the most torturous 3D games available in Linux today (UT2004, Doom 3, Quake 4, even Half Life 2+ if you know how to make that work). There may come a day when we'll all switch to ATI (once the FOSS driver is working). But that looks to be at least a year or more away. With the Nvidia, there are some working drivers from Nvidia (proprietary), you may have to compile the kernel module (not hard). I recommend version 100.14.19. There are lots of problems with ATI even in Windows... If you don't need games, then even the lower end Nvidia cards are fine. Might even find somebody throwing away an old one.

I also use this computer to play games in Windows (the only use for Windows I have, actually). Thus 3D performance is crucial.

Thus 3D performance is crucial. Wish I had better news. Even Radeons that "work" have always caused me grief. |
