[Bug 201342] Re: Uses single refreshrate for separate X screens
Noticed this again recently because the primary screen appears to have switched between driver versions. Despite what's said above, on my hardware the driver seems to pick the screen it syncs to and does not respect the primary setting for this purpose. Previously this meant that I had flipped my monitor cables around (and flipped the screen config around in Windows) so that the synced display was my primary display and the tearing was on the secondary. Now the sync has shifted to the other display so I guess I'll be flipping my cables around again. This is most noticeable when playing video as one does not drag screens around constantly. I have a feeling that in many cases bugs like #151674 are probably also attributable to this fault. Isn't this down to some awful kludge in X that identifies displays by a concatenation of their resolution and refresh rate - the end result being that you can't have two displays with identical resolutions and refresh rates because that would mean X couldn't tell them apart? It would seem to be worth checking this rumour out but I don't have the time or grok C and X well enough. -- Uses single refreshrate for separate X screens https://bugs.launchpad.net/bugs/201342 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 201342] Re: Uses single refreshrate for separate X screens
I can confirm this issue on my Dell laptop (D830, Quadro NVS135M GPU with 190.18 binary nvidia drivers). My external CRT operates at 85Hz, while my laptop runs at 60Hz, but Compiz can only use one refresh rate for both screens. Compiz should be able to set one refresh rate per x screen, instead of one refresh rate for everything (glXSwapBuffers calls are independent for each screen / OpenGL context). -- Uses single refreshrate for separate X screens https://bugs.launchpad.net/bugs/201342 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
