hornett Share Posted April 2, 2004 Hi there, in every distro I've ever tried, the transparent dragging effect on the desktop is very slow if i use the 'nv' driver for X. If i use the official 'nvidia' or even 'vesa' drivers, the transparency is very smooth. To recreate what I'm talking about, start in on corner and drag the mouse quickly across to the opposite corner on a blank desktop. PS the new version of FC2test is amazing! I'm just upgrading it to 2.6.4 with apt-get :D Link to post Share on other sites

I'm just upgrading it to 2.6.4 with apt-get :D well depending on your hardware specs and the fact that X doesn't use dma support for its graphics rendering any transparent items are going to run a little slow. enabling graphic specific drivers for your video card does help as you can see in your tests. i still think dma should be added to X, life would be perfect and all the computer nerds would have supermodel girlfriends that dont think, just cook, clean, and well.. the other thing ;-p Link to post Share on other sites
hornett Author Share Posted April 2, 2004 But kemical- what I dont understand is why the VESA driver runs transparency a lot faster than the nv ones. I thought the VESA was a very basic, legacy option there for compatibility not performance. Link to post Share on other sites
kemical Share Posted April 2, 2004 could be a number of things, i dont know your machine so i would not be able to troubleshoot it Link to post Share on other sites
hornett Author Share Posted April 2, 2004 OK, so am I right in thinking that this situation is not usually the case with the nv drivers and a GeForce MX card? Link to post Share on other sites

hornett Author Share Posted April 2, 2004 OK thank you very much for your help, I will have another hunt around the net for some answers. Link to post Share on other sites
Tek Share Posted April 2, 2004 Why would you want to use the nv driver over nvidia anyway? The nv driver has no 3D accelleration. Link to post Share on other sites
hornett Author Share Posted April 2, 2004 Because even the latest nvidia driver makes X crash under the 2.6 kernel. Link to post Share on other sites
hornett Author Share Posted April 2, 2004 Yes, I am torn between 2.4 /2.6 over this also. 2.6 runs so much faster for me thom it is unreal. Link to post Share on other sites
