https://bugzilla.kernel.org/show_bug.cgi?id=42616 Summary: Radeon Kernel Mode Setting sets wrong mode Product: Drivers Version: 2.5 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx ReportedBy: thomas.jones@xxxxxxxxxxx Regression: No I have a Radeon HD 3470, connected to a Dell P2010H monitor via Display Port. The monitor's native resolution is 1600x900, and everything works correctly with UMS, however if I use KMS I cannot use that mode, I can use at least 1024x768, 1280x1024, and 1152x864 with KMS, but no matter how I try I cannot get it to work in 1600x900. I have tried with the CVT timings, (reduced blanking and not) and with the ones provided in the monitor's EDID. If I attempt to set any of those modes (the 1600x900) with KMS on the monitor claims that I'm using an unsupported mode. UMS works just fine though. I'm running Fedora, and I don't think this is a regression in the kernel since I don't think this computer has ever worked with KMS. Right now what I've done is I have set the kernel command line to boot with 1152x864 and KMS, then I tried to use xrandr to change modes and the monitor just complained. dmesg doesn't seem to have anything useful to say, and neither does Xorg.0.log -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
