Created attachment 13661 [details] Xorg.0.log of the session. On my setup: * Mandriva Cooker (updated as of 2008-Jan-10). * Pentium 4 2.4 GHz. * GeForce 4 MX. * Screen: ViewSonic VA-903m * xorg-x11-7.2.0-2mdv2008.0 * Nouveau drivers - mostly up-to-date git master, installed using the instructions on the wiki. * x11-server-1.4-18mdv2008.1 I'm getting jitters on the screen - sudden movements of several pixels in a certain region that disappear after a fraction of a second. I don't recall seeing it a week ago or earlier. I'll attach an Xorg.0.log file and an IRC log of #nouveau.

Does this still occur with current git? I think i once saw my screen in a similar state, some regions more than others, were the letters were shaking a bit. Like watching a bad crt, when in fact it was a digital flat panel. Does it occur consistently, is there anything you can do to speed it up?

I'm not sure if I had it since I upgraded to kernel-2.6.24 and updated Nouveau with it. > I think i once saw my screen in a similar state, some regions more than others, > were the letters were shaking a bit.

However, sometimes it appears shortly after I restart X from the command line (K -> Logout and then startx again). Regards, Shlomi Fish
Could you make a picture of it?

Any chance you could try Option "Randr12" in your device section? It's a new modeset system, that will hopefully replace the old one in the forseeable future.

So, what happened? Could this be a hardware failure, e.g. gpu running hot and having the crtc scanout jumping?

However, my old GeForce 4 card broke, and had to be replaced, and I bought an ATI Radeon HD 2600 card, which I'm using with the radeonhd driver (and which works mostly perfectly). I don't remmeber what happened after I enabled randr12. Feel free to close this bug. Regards, -- Shlomi Fish
