Summary: Missing EDID through NV11 (nouveau) driver causes suboptimal modeline Product: Drivers Version: 2.5 Kernel Version: 3.3.0 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri@kernel-bugs.osdl.org ReportedBy: petr.pisar@atlas.cz Regression: Yes

Since kernel 3.3.0, I cannot get capabilities of my CRT monitor connected to NV11 (GeForce2 MX/MX 400) graphics card. This causes setting graphics mode in framebuffer console and X11 to 60-MHz vertical refresh rate.

Last known working kernel is 3.2.11 (85 MHz).

The change is graphics output names is solely driver issue. The card has only one physical connector.

The missing EDID data can be seen in Xorg log which I'll attach.

Adding video=1024x768M@85 kernel parameter helps, but there is some weird horizontal offset on the screen. Adding modelines that have been autodetected by Xorg with old kernel into xorg.conf fixes the refresh rate issue in Xorg running on 3.3.0 kernel.
