Re: Troubleshooting X performance problems?
Try playing with the InitialPixmapPlacement setting available with the nvidia-settings command to see if it makes any difference in the performance. From a terminal window:
where x is a number 0 - 4. No restart of X is necessary. Try with different values and see if there is any improvement. |

Thanks, I just tried what you suggested for values between 0 and 4.. unfortunately it doesn't seem to improve anything. I'm rather confused -- I figure an NVidia Quadro is a pretty powerful card. My smaller D420 laptop, with integrated intel graphics, handles it much better than this bigger laptop.
Is there some de-facto standard for measuring graphics performance? Maybe that would help debug what's wrong here. I suppose maybe the number that glxgears reports, but I have no benchmark to compare it against, nor do I really trust those numbers as any indication of graphics performance.. |

| Your issues are with 2D performance. glxgears is a 3D application. You may want to look at gtkperf for benchmarking 2D. Although that is only likely to tell you what you already know: 2D rendering is slow.
What version of the nVidia driver are you using? |

2 edits | Epyon9283: thanks, I'll have a look at that. How is the 3d performance with those drivers? I just looked at their page, and they make no mention of supporting nVidia Quadro cards, though... I'll poke around a bit.
benyto: Thanks. I'm using the latest version of the nVidia driver, which is 185.18.14 (for x86_64). My old desktop, with its GeForce 6600, never showed any such problems (though to be fair, it's a desktop video card, of course). |
